[RCSE] Re: Soaring V1 #8465
Chip, Soon I don't think you will need that regulator. Hitec just released a new set of receivers and they are all rated for 3.7 to 7.4V. Funny but that maps to 1 and 2 cell lithium. ;-) Best Regards, Ed Anderson From: Chip Willis [EMAIL PROTECTED] To: soaring@airage.com Subject: Lithium Ion batteries Message-ID: [EMAIL PROTECTED] FWIW, I haven't seen many people discuss it, but I have been using Li-ion batteries for a while. I flew the entire two day contest at the Fall round up, on a single charge. I use Fromeco 2400 two cell batteries, and I checked the voltage periodically and I had plenty to spare. I could have flown for another two hours I estimate. Again, this is in a 3 servo Ava so not too much draw there. I use a MPI 6v regulator to step down the volts, and so far so good. I am building a Supra now, and It is quite an investment, so i'm thinking of running dual batteries in it. I was flying giant scale and running dual rx batteries is almost standard over 30 percent airplanes, and with the sizes available, redundancy kinda makes sense. Anyone else doing this or thinking of it? Chip RCSE-List facilities provided by Model Airplane News.

[RCSE] Re: Soaring V1 #8466
Darwin, The excitement around the DX7 is the promise of glitch free, shoot down proof flying. Most of the soaring population are having a great time on lesser radios than the 14MZ, the 9303 or even the Futaba 9C. For them the DX7 has plenty of capabilities. The Spektrum DX6, which was released last year for parkflyers and small gliders. It received strong acceptance and has been extensively field tested by users. There are literally hundreds of reports posted on the forums. Spektrum suggests 1500 feet for the radio/receiver, but there are many reports out beyond 3000. That doesn't surprise me as my Hitec receivers are rated for a mile but I have seen informal reports that they still work at 2 miles. Seems a 50% derating is standard procedure. The real issue has been around signal view. The DX6 receiver is actually two receivers in one with two antenna oriented at 90 degrees. If one loses the signal, the other can still hold it. But, due to the short wavelength, there was concern that large dense RF shielding objects, like glow and gas motors or fuel tanks, could blank the signal to both antenna. That is why the new receiver has two pieces that spread apart by 2 inches. This makes it much hard to blank the signal to both receivers. http://www.spektrumrc.com/DSM/Technology.aspx My interest will be on how it does with carbon fuselages. These carbon fuselages give many 72 MHz receivers trouble, or at least reduces their effective range. Also the DX6 had warnings about metallic coverings and white coverings with are rich in metallic content. I don't know what they are saying in that regard these days. If you read the field reports, the DX6 has performed at longer ranges and with fewer incidents then might have been expected. Certainly it has proven to be at least as good as the 72 MHz FM systems when working within 2000 feet in electric and glider models. And there are a number of people who have flown them in their glow planes and reported good success. If the DX7 and the new receiver live up to their advertised performance, then it should not take Spektrum very long to get this technology into a JR 9303 as their radios are based on JR chassis. The DX7 may not be up to contest radio standards but I wouldn't be surprised if that is intentional. Open class sailplanes are probably the models that are flown at the greatest distances of all hobby RC models. Perhaps they are not ready to target the contest sailplane market.

[RCSE] Anyone have Hartmut's new email address?
Hi Guys, I was wondering if anyone, (including Hartmut if you are reading this) has his email address, I had a question about the Picolario sensitivity settings. For me it a fun toy but since he was the USA distributor, he had a better idea about how to set them for TD use. Looking for his email address Gordy
[RCSE] Two things that can annoy a Picolario
Hi guys, John Luetke and I were playing with the recent version of the Picolario and found that no matter what we would do we couldn't get it to 'zero' the altitude. Turns out that the best time to test it is not after flying all day in a rain storm ;-) Blowing in the pick up tube to get a sound reaction, puts moisture in the chamber and that will always cause a misread. But a cold unit will show the same thing. They are designed for accuracy once 'warmed' up and running, so by turning it on for about a minute, then turning it off to re calibrate the altitude should do it. Storing it in a warm dry place is best between uses, so if its in your fuse, in the garage, car of some such where it gets cold and warm it can pick up humidity. The fix is to bring it in and hold it under an acetylene torch for an hour or soof if you don't have that, some where warm and dry. Probably saving some of those little desiccant bags might be a good thing to keep with it. GordyLouisville for a day or so, next stop...North Jersey
Re: [RCSE] Spread Spectrum
I have to say that I view this is the single most important development in RC since the advent of proportional radios. SS offers essentially glitch free operation while eliminating the possibility of being shot down by some knuckle-head. It will make running a contest a breeze. No more worries of flight groups based on frequency conflicts. Contests will run faster and this may even enable us to try some different formats. Plus think of having 40 plane flight groups!! SS will revolutionize other areas of RC as well. I know this pains many of you to think about, but there is a great big ol' world of RC out there and this will have an enormous impact on everyone in the hobby. The current physical design of the DX7 type of RX may make some installations challenging, but I think that these issues will be successfully overcome as time passes. Plus, other vendors may have deferent solutions. What I know is that if a radio maker does not offer SS very quickly that they will be left in the dust. And I predict it will be a very rapid transition due to the overwhelming advantages of these systems. And Chuck pointed out my major worry - physical blanking. The dual RX set of the DX7 appears to solve this problem. Others say they have a different way to do it, but in the end I think this will not be a serious issue. Exciting times to be sure.

Re: [RCSE] Lithium Ion batteries
Very different technology; The charge algorythms used within cellphones and other personal equipment are locked down to the cell-count for that device, with other safegaurds. The original question about using Lithium technology for sailplanes, at the moment it does not warrant their use for a couple of reasons. First the form factor, those cells which would adequately meet the current demands are relatively large (18650 - 18mm dia x 650mm length). Although the size of prizmatics would fit our current moldies, they offer no where NEAR the required current demands due to their internal structure. I suspect the poster who used Lithiums in his sailplane was able to do so because the aircraft's size allowed it...

Re: [RCSE] Lithium Ion batteries
prizmatics would fit our current moldies, they offer no where NEAR the required current demands due to their internal structure. I am curious what you feel are the current demands of a typical 6-servo TD ship. I can give you some documented loads from other uses. Raptor 50 heli with 5 mid-sized digital servos in 3D - 2 amps average, 5 amp spikes. (Fromeco has data on their site) 40% IMAC plane w/14 Large digital servos - 3 amp average, 20 amp instantaneous loads during snap roll series. The EMCOTEC site has this data. 10 large digital servo 38% Extra (mine) - 2.5 amp average current load. 8 large digital servo 33% Edge - 1.5 amp average load. I have also determined that my 6-mini-digital servo TD ships average about 350 mA for the load. RCSE-List facilities provided by Model Airplane News.

[RCSE] Lithium Ion batteries
Why do so many people want to put a fire bomb in a transmitter or in a model other than electric? The NiMh batteries in my Evo will last about four times longer than I will ever fly in one day. If, by chance, I do fly longer than normal, then I will simply recharge the transmitter with the SiriusCharge mounted in my van. In fact, I normally use the SiriusCharge to charge my transmitter and model on the way to the field so I always start with a full charge. I haven't been very happy with the service I have gotten with the NiMh and Li-ion batteries in my cameras and computers so I have decided to stick to Nicads for my model and replace the NiMh battery in my Evo with a 1100 mah Nicad battery when the existing battery dies. I will only have enough battery to fly three times more than normal but I can live with that. Chuck Anderson RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Lithium Ion charging
One can not put too fine a point on Doug's comments about NOT using your NiCD/MH charger on Lithium technology...

Well, generally a charger's job is to put a certain amount of current into your battery, and a NiCd/NiMH charger does that as well as a LiPo charger. What really differs is how they turn off -- a NiCd/NiMH charger turns off when it sees a peak (or just after a certain amount of time for an old one) and a LiPo charger starts slowing down at a certain voltage, and finally stops at 4.2 volts/cell. So, if you sit there and watch your voltage as you charge your batteries very carefully, you can charge your LiPo pack with a NiCd charger. However, the charger will not turn itself off automatically, and will happily overcharge your battery if you forget to turn it off yourself -- which will ruin the battery at best, and could cause it to catch fire if you're unlucky. It's easy to get distracted and forget to watch the charger, so I'd strongly suggest not doing this. You can get a low end LiPo charger for 2-3 cells for as little as $12 (http://www.nitrorcx.com/eeclipolilib.html) if your pack has a balancing connector, and for $25 (http://www2.towerhobbies.com/cgi-bin/wti0001p?I=LXHNW5) if not. Or you can get lower power 12v-110v inverter for around $20 if you want to power your charger at the field. Considering that your battery probably costs more than these chargers, and is so easy to ruin just by getting distracted, I'd strongly suggest just getting the right charger -- Doug McLaren, [EMAIL PROTECTED] RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Lithium Ion batteries
More than what a prizmatic can offer when it is needed most...howzat? Average consumption is usually not the issue, high (current) loading which causes the PTC (an over-current protection device present on all lithium cells) to activate and reduce current flow is. If activated by exceeding the cells operating parameters, it essentially heats up rather quickly (time-based on the load excursion) reduces current flow to near-zero. On prizmatics, where the cell's specification is to deliver relatively low current for long periods, it can act rather quickly and take it's sweet time recovering. This goes for all PTC's actually. Another trait is the recovery time is not consistant from cell-to-cell (PTC to PTC). We did experiements to look at the complete system including awg on harnesses, connector losses, and various load supplies (NiMH versus NiCD) as it relates to high speed flight. We rigged flaps and ailerons to measure actual surface deflection (using separate onbaord linkages and positioning measuring equipment) to record deflection during launch phase and hi-G pull-outs (where surface loading is the highest) and then proceeded to change the above mentioned parameters. Amongst other things, we observed servos falling below their operating V thresholds, especially on configurations where PWR and GND have been shared between more than one load (not something I recommend at the best of times). Average consumption tells you little. It is the loading that occurs at maximum surface pressure that dictates operating system integrity. On most aircraft this is hardly noticeable. But those which may employ Lithium thechnology where the PTC has been activated, you will notice in a hurry... Simon Van Leeuwen PnP Systems - The E-Harness of Choice Radius Systems Cogito Ergo Zoom Quoting Bill's Email [EMAIL PROTECTED]: prizmatics would fit our current moldies, they offer no where NEAR the required current demands due to their internal structure. I am curious what you feel are the current demands of a typical 6-servo TD ship. I can give you some documented loads from other uses. Raptor 50 heli with 5 mid-sized digital servos in 3D - 2 amps average, 5 amp spikes. (Fromeco has data on their site) 40% IMAC plane w/14 Large digital servos - 3 amp average, 20 amp instantaneous loads during snap roll series. The EMCOTEC site has this data. 10 large digital servo 38% Extra (mine) - 2.5 amp average current load. 8 large digital servo 33% Edge - 1.5 amp average load. I have also determined that my 6-mini-digital servo TD ships average about 350 mA for the load. RCSE-List facilities provided by Model Airplane News.

RE: [RCSE] Lithium Ion batteries
I use Li-Ion in 3 HLG's 7-9 oz ships AUW, and three 2M ships along with 2 UNL ships. I use cell phone batteries in 1S and 2S configurations yielding 4.4+v. I also use Cell Phone chargers for charging them. Most if the Batteries and all the chargers came from discarded cell phones. I collected them from cell phone shops that have upgraded customers and were glad to part with them. I use 1S or 2S because I have RX that work fine with them and have had no problems in the past 3 years. I went to a 2-day ladder contest in Michigan and realized I forgot my charger. No problem. I didn't need it. If you charge a 2S 18650 (from old laptop computers) to 4.4v it will run for days without needing a recharge in my RES ships. One 14430-600mah will last several flying sessions in my 60 Little Bird II or QFII HLG. I have also used some of the flat rectangular cell phone batteries in my HLG's in the past. They are harder to fit in the small ships but the 2M and up are great candidate. If I were worried about current draw I would go to 2S, 3S or even 4S with an ESC to step down the voltage. The weight savings and convenience is phenomenal. Not to mention that you can't beat the price.

RE: [RCSE] Lithium Ion batteries
Have you at any time measured that current draw under load on the larger ships? Are you aware of the specific ratings for the cells in question and the types of PTC's employed? Do you understand what the maximum draw might be demanded of that particular cell/pack? The point is, although you have not observed problems this does not merit blanket approval of their operation in all circumstances. I wish folks would refrain from the mindset if it works for me it must be OK to recommend to others without reservation, which therefore gives the green light to others that indeedy there is no problem... I'm happy they are working for you, but by no means jusify their use without evidence to show that: a) actual supply V remains above RX and servo thresholds b) onboard PTC's have current limits that match the application c) their eservice life has not already been used within their original application(s) Quoting John [EMAIL PROTECTED]: I use Li-Ion in 3 HLG's 7-9 oz ships AUW, and three 2M ships along with 2 UNL ships. I use cell phone batteries in 1S and 2S configurations yielding 4.4+v. I also use Cell Phone chargers for charging them. Most if the Batteries and all the chargers came from discarded cell phones. I collected them from cell phone shops that have upgraded customers and were glad to part with them. I use 1S or 2S because I have RX that work fine with them and have had no problems in the past 3 years. I went to a 2-day ladder contest in Michigan and realized I forgot my charger. No problem. I didn't need it. If you charge a 2S 18650 (from old laptop computers) to 4.4v it will run for days without needing a recharge in my RES ships. One 14430-600mah will last several flying sessions in my 60 Little Bird II or QFII HLG. I have also used some of the flat rectangular cell phone batteries in my HLG's in the past. They are harder to fit in the small ships but the 2M and up are great candidate. If I were worried about current draw I would go to 2S, 3S or even 4S with an ESC to step down the voltage. The weight savings and convenience is phenomenal. Not to mention that you can't beat the price.

The original question about using Lithium technology for sailplanes, at the moment it does not warrant their use for a couple of reasons. First the form factor, those cells which would adequately meet the current demands are relatively large (18650 - 18mm dia x 650mm length). Although the size of prizmatics would fit our current moldies, they offer no where NEAR the required current demands due to their internal structure. I suspect the poster who used Lithiums in his sailplane was able to do so because the aircraft's size allowed it... Simon Van Leeuwen PnP Systems - The E-Harness of Choice Radius Systems Cogito Ergo Zoom Quoting John [EMAIL PROTECTED]: I wonder if all the people that are still so worried about charging Li-Ion batteries are charging all the cell phones in the family outdoors in an ammo box. :) No different technology.

RE: FW: [RCSE] Lithium Ion batteries
Exactly! If Fire is a worry I hope you have your cell phone near your back pocket and not near your front pocket. Ouch! Just think of what could happen if you stumble and fall against something and the battery shorts! A flameout on the front side is not something I would like to experience! But then falling backwards would not be much better! John P.S. If flameouts really were a problem we would have heard of it on 60 minutes. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, October 20, 2006 5:26 PM To: John Cc: RCSE Subject: Re: FW: [RCSE] Lithium Ion batteries No more risk of what, fire? If the same devices with a similar charge regime are used under the similar circumstances...the risks are the similar. Quoting John [EMAIL PROTECTED]: I use the cell phone chargers as I would with a normal cell phone. I plug the charger in and leave it (sometimes for days). The chargers are UL certified to put out only 4.4v or 7.8v and will not overcharge the batteries. Granted, all things can and will fail but if you leave your cell phone on charge over night (in your house) your running more risk than I do in the garage with isolation.

RE: [RCSE] Spread Spectrum...Chat Gold, Fools Gold or ?
Ok guys fact time We've been flying the DX7 tx and AR7000 rx for some time now in over 200 different planes. From GS aerobatic planes with 150cc ignition engines to Turbines and Heli's (gas/glow and electric). BTW-Turbines are THE most unfriendly RF enviroment out there in the RC world. And even sailplanes with carbon kevlar fuselages and carbon booms. Altitudes achieved during testing were past 2000ft AGL and not directly over-head. These are facts and not smoke and mirror tricks or slick advertising campains. For those who know me you know I wouldn't BS about any of this. And for those who don't well ask someone who does. The technology is here and it works.
