RE: [RCSE] GreatPlanes Triton charger
Jim, Does the charge HAVE to be stopped after 12~16 hours of charging? I have an Alpha4 charger which charges until the NiMH battery peak had been reached and then it switched to C/20 indefinitely. Thank you for the info. Cameron -Original Message- From: Jim Laurel [mailto:[EMAIL PROTECTED] Sent: Thursday, May 19, 2005 1:30 PM To: Cameron Cc: rcse Subject: Re: [RCSE] GreatPlanes Triton charger Cameron, Formation charges are required for preparing new NiMh packs. You simply charge the pack at a current level equal to 1/10th of the pack capacity for around 12-16 hours. For example, a 1000mAh pack would be charged at 100mAh for 12-16 hours. A 2200mAh pack would be charged at 220mAh. On my Hobbico charger, I use the 250mAh setting. It's not too critical. Just try to get close. Due to manufacturing variances, all battery cells of the same type are not truly identical. When put together in a pack and charged, some will charge faster and peak early, which will fool most modern peak detecting chargers, leaving the laggard cells in a state of partial charge. Slow charging at capacity/10 allows all the cells in a pack to get fully charged without causing a thermal crisis in the cells that have peaked early. After 2-3 charge/discharge cycles like this, the cells reach a sort of equilibrium, charging and discharging together at relatively similar rates. This is what you are trying to achieve with the initial formation charges. You want all the cells in your pack to peak at the same time, and discharge at the same rate. Once the pack is conditioned like this, you can use the peak detecting fast chargers with no problem. Cheers, --Jim On May 19, 2005, at 10:12 AM, Cameron wrote: Jim, What is formation charges?

That helps. Yes, I set the timer, which goes up to 960 minutes (or thereabouts), which translates into 16 hours - perfect cutoff for formation charges. The downsides to using the Triton for this are: 1) You have to remember to reset the delta peak, or you will fry the next pack you try to quick charge! 2) The Triton only goes down to 100mAh, so you can only do formation charges on packs of 1000mAh capacity or more. It's useless for formation charges on, for example, handlaunch packs. I keep a Hobbico R/C Multi Charger around, which has current settings ranging from just 25mAh to 500mAh. I use it all the time for slow charging my RX packs and transmitters fitted with 2100mAh NiMh packs. Another plus is that it runs on 110VAC - very convenient! It's a very useful item at just $29.99 new from Tower. Everyone could make good use out of one of these simple inexpensive devices, IMHO. http://www2.towerhobbies.com/cgi-bin/wti0001p?I=LXL331P=7 You can use a timer with it, but the catch is that a small design flaw in the charger allows the pack to DISCHARGE into the charger itself when power to the charger is cut off. I made a few adapters with inline rectifier diodes from Radio Shack that solves the problem. --Jim On May 19, 2005, at 6:06 AM, Jon Stone wrote: Jim, The Triton is a great charger for the money. There are a few dumb things about the software, such as the way it erases the total mAh put into a NiMh cell after it goes into top-off mode, but by and large it is a very good unit. And again, you can't beat the price. You can press the right square button after the charge is done and review the Mah the charger put into the battery, before the top-off charge. Same way you can review up to 10 charge/discharge values. Have to do it before disconnecting the pack, or before pressing the left button, though. I use it for all sorts of cells, including NiCd, NiMh, and LiPo. It can even be tricked into doing a formation charge on NiMh packs by rning the delta peak setting up really high. Thanks for the trick about forming packs. I had not figured that one out. I had been keeping another charger around just for that feature. I assume you also set the timer to the # of hours you want to charge. Jon RCSE-List facilities provided by Model Airplane News.

RE: [RCSE] HELP: JR XP9303 setup with six servo wing?
Sherman, In my case I am considering a large 4.5 meter (177) scale sailplane. The sailplanes wing uses six servos three servos per side. The wing is designed for three servos per side. (I would prefer not using mechanical linkages, and using software mixing instead.) Thus the wing servos would operate L R flap, L R inboard aileron, and L R outboard/tip ailerons. I would like the outboard ailerons to match the movement of the inboard ailerons but possibly reduce the total travel of the outboard ailerons to 60~80% travel compared to the inboard ailerons. Depending on the sailplane characteristics, e.g. adverse yaw, I may need to increase or reduce the percentage of mixing and the ratio of movement between the outboard and inboard ailerons.

Can I setup the inboard and outboard ailerons to move by the same and/or different amounts? The answer is yes. However that is a very incomplete answer. What do you want the outboard aileron to do? Sounds like a stupid question, but it is not. What do you want the outboard Ail to do in lunch mode? Cruise Mode? Thermal Mode? Landing mode? It is easy to get the tiperons to follow the ailerons. If that is all you want, then why have them servo driven? Mechanical connection is much lighter. So, until you figure out what you want them to do, there is no way to answer the question.

So, the discussion about the suitability of Corvettes for hauling sailplanes got me to thinking more about my next choice of vehicle. It should have the following attributes: 1) Space to haul 2 unlimited planes and a 2 meter plane + winch, toolbox, 1 Optima battery, turnaround, radio cases + at least 1, preferably 2 passengers 2) Fast and comfortable for those long hauls to away contests 3) Reasonable fuel economy (20-21mpg highway minimum) 4) All wheel drive, since here in Washington the passes are often a mess, roads are often wet, and I like to ski after work in the winter. 5) Decent driving dynamics 6) Enough clearance to travel forest service roads to slope sites 7) NOT a minivan Here's my short list: --Volvo XC70 --Audi A6 Avant --Audi S4 Avant (not sure if long enough) --Dodge (Mercedes) short wheelbase Sprinter (no AWD yet, but likely for 2007 model year) --Subaru whatchamacallit wagon I have an old Land Rover 110 that has been a project vehicle for 2 years and is now nearing completion.

Plus, the HVAC system is useless - pretty much windows up or down. In the plus column, however, it will get you to any slope site you like and then some.

Ok, ok, everyone... So I know the inclusion of the Sprinter got everyone confused. That was a pretty random item on my list and I would be hard pressed to choose that one. It is, however, a very interesting vehicle. These and similar designs, such as the Ford Transit will eventually replace the traditional American-style full size van. They have superior capacity, maneuverability, economy, and handling. I'm inclined against SUVs as well, due to handling and fuel economy. They do have the space and the ability to travel to slopes, though. My wife has been driving a Land Rover Discovery for almost 10 years now and it is an excellent vehicle. But it eats gas like crazy and is a bit tiring when you're flogging it along on a long trip. If you need the weight bearing capacity, it's great, and it is very very good off road. It seems like a station wagon or car-based SUV might be the best choice. It should be big enough but still a reasonably entertaining drive, which kind of rules out the pickups and truck-based SUVs. However, some of the car-based SUVs will be worth a look. Volvo loaned me an XC90 as a journalist demo once when I was doing an article for Slate's Well Traveled on Scandinavian design. I drove it through Denmark, Sweden and Finland in February, so have a good idea of its winter abilities. I liked it quite a bit, but was a little bothered by its front wheel drive bias. The front wheels would always scratch for grip for a few moments before the abs kicked in and directed some torque to the rear wheels. But that was minor. The best thing about the XC90 was the really clever and flexible rear seating set up. You could carry 4 passengers with skis (or sailplanes) down the middle and gear in the back, seven passengers with all the seats unfolded, fold all the seats and have a big flat space for cargo, 4 passengers with something long running up one side, remove seats altogether or several other combinations. A few hours carving up some rural roads in a good handling car is always good fun! I'm not convinced the Volvo XC90 or XC70 is up to that. The Audi S4 would be really sweet, if only it is big enough for unlimited sailplanes in bags. I'll have to measure it and see. With 340hp, 6 speed stick and AWD in a small station wagon, it's sure to be very entertaining indeed. But clearance might be an issue. The Allroad is just about perfect, and has the clearance, but it's a bad time to buy one, as Audi is updating the styling across the line, and Allroad is due. Maybe a new one by next year, unless they decide that it doesn't make any sense sitting in between the A4 and A6 Avants. I would also assume that they are going to do an S6 Avant, like the A4/S4, ground clearance issue will be a problem. --Jim RCSE-List facilities provided by Model Airplane News.

RE: [RCSE] sailplane info wanted
I own a Vulcan2M. It is a very nice sailplane. One thing though -- when you balance the sailplane according to the specs in the instructions it will have a very aft CG and be quite twitchy to fly. I would recommend moving the CG between 1/4 to 1/2 inch forward. I usually launch the sailplane by which or hi-start and then head out to search for thermals. It handles fine with a quick roll rate but it is sensitive to pitch. I like the sailplane a lot and fly it frequently. Cameron Ninham RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Radio Charging Error-advice please
Hello Scobie, Yes, the JR charger for the RADIO (only) is REVERSED. If you pluged in a charger from a different brand (with reversed polarity) into the radio it will short out the fuse in the TX. You will have to replace the fuse. Regards, Cameron Ninham --- Scobie Puchtler [EMAIL PROTECTED] wrote: Y'all know I'm no electronics whiz, so I'd appreciate a little advice if any is necessary: I just charged both of my JR TX's for several hours using two wall chargers.

The radio that was on the Hitec charger had zilch, wouldn't come on, LCD display didn't even flash for a second. Seemed very weird at first, but once I realized it had been on the wrong charger, things started to make more sense. I've now got the uncharged (mis-charged?) radio charging on the JR charger, as was the original intent.

Any reason to expect that I've done any damage to the battery? Anything I should be doing or checking? I already put the 'correctly charged' battery in the TX that was on the Hitec charger and everything works fine.

NiMH are endomthermic, while NiCD technology is exothermic. This means as an NiCD becomes fully charged, the increase in heat causes an increase in internal resistance, which lowers the charge V, which trips the peak-detect circuitry. Efficient cells like the KAN's do not induce a voltage depression adequate enough to trip the peak-detect, so the charger keeps pumping in the current. NiCD chargers are great at ruining perfectly good NiMH cells. Then the cells get blamed for poor performance... Quoting Regis White [EMAIL PROTECTED]: I bought an Alpha 4 about six or seven years ago and have been quite happy with it. But (there is always a but) it did not have a separate discharge function - it only cycled (once). NiCads like to be left discharged I have been led to believe. Ni-MH on the other hand like to be fully charged - and can be harmed if fully discharged. So I have replaced most of my NiCads. What I learned was that I could not safely charge them on the Alpha 4 'Peak' function or even the 'c/10' function - only the 'Fast charge' function. Recently I acquired two KAN Ni-MH 7 cell packs and was surprised to find that the Alpha 4 could not automatic charge them safely - they got very hot. Since both packs got very hot, I suspect the KAN cells are just not compatible with Alpha 4 technology (which is easily 20 years old). (I mean we can plug in a cell phone to charge and just forget it.) Is there something about the KAN type cells that are different or is this an anomaly?

RE: [RCSE] What are airfoil polars and how do I read the charts?

Message-ID: [EMAIL PROTECTED] I have Profili and it lists polars as one of its great features. What are they, how do I read them, and what do they tell me? Thanks, Jay Hunter - End Original Message- Jay, unfortunately you have asked a question which will take several text books to explain. Many people (aeronautical engineers etc) go to colleges just to better understand airfoil polars... *smile* I will try to give a *SHORT* explanation without going into lengthy details: An airfoil polar represent the aerodynamic characteristics of an airfoil. This is usually represented as a graph showing lift vs. drag coefficients, lift vs angle of attack, and lift vs pitching moment. An airfoil is placed in a wind tunnel, and lift, drag, pitching moment and angle of attach measurements are taken at various wind speeds and calculated as the local Reynolds number. As a general rule of thumb (gross exaggeration) you want to minimize the drag for a given lift coefficient. As is the case in aeronautics in general, there are always tradeoffs. When an airfoil has a good lift vs drag value at one point, it may be bad at another, etc. etc. etc. The trick is to find an airfoil which has the desired characteristics at the important phases of flight for which it is intended to be used. E.g. a trainer airfoil might have a high lift coefficient, higher drag coefficient (to make it fly slower or come down faster), low pitching moment and benign stall. But a F3B racer might have a lower lift coefficient (a high lift coefficient is not needed as much as it flies faster)but a very low drag coefficient at racing speeds. In another example, with a tailless flying wing you want very little moment so that the wing does not tuck under at flying speeds... etc etc. etc. Makes sense?

Re: [RCSE] How to Determine the Correct Incidence

Which I believe was the original question. It was about the V-tail incidence on the Artemis. On 9/17/04 4:58 Phil Barnes wrote: What I really should have asked is: How do you determine the proper incidence on a sailplane? It is less draggy to fly around with no deflection or minimal deflection on the elevator/ruddervators. In setting the correct incidence all you are doing is setting the tail incidence relative to the wing incidence such that the elevator/ruddervators are neutral at the most commonly used airspeed. Phil ~~~ Bill Malvey Hello Phil Bill, There are a couple of ways to determine the wind incidence, and many people have different opinions and preferences based upon their strategies. Here is my personal preference and opinion: I feel that the most important phases in a sailplane's flight envelope is the thermalling and high speed cruise (sprinting from one thermal to another thermal) phase. Total drag is has a greater impact during the high speed cruise phase. So I try to optimise my sailplanes configuration to minimize drag during this phase. Determine what the speed is that the sailplane will typically fly at during the high speed cruise. Then, using the particular airfoil used on the sailplane, calculate what the lift coefficient is at that given speed and conditions. Use the airfoil's CL vs alpha polar to determine the angle of attack at which this CL would occur. Now that you know the angle of attach, I like to use this angle as the wing to fuselage incidence angle -- setting the wing incidence at this angle will allign the fuselage with the general freestream airflow, and thus minimize the drag caused by the fuselage at that given airspeed.

Re: [RCSE] aileron differential, which way?
Danny, aileron differential should be more up than down. In simple layman's terms (non-aerodynamic), think of it as the wing is already producing lift, you would need more up aileron to "counter balance" the lift than down aileron (as down aileron increases camber and thus lift, where the wing is already producing lift).

Should there be more up or down throw, and why? From what I remember, more up is required. And the reason is to prevent adverse yaw. More throw on the up aileron causes more drag and helps the plane yaw in the same direction of the turn. Am I remembering correctly? TIA, Danny RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] aileron differential, which way?
Danny, sorry - I misread your question. I thought you were asking as to how to remember whether it is more up or down aileron... Anyway, to answer you question better. For aileron differential, you want more up aileron than down aileron. The reason why is that with DOWN aileron, you INCREASE the wing's (or airfoil) camber. With an increase in caber, you increase the cl. Opposite is true for the other side. When you RAISE the aileron on the other side, you decrease with wing's camber in that region. With decreased camber you decrease the operating cl. More lift on one side of the wing (more camber, thus more cl) increases the [vortex] induced drag. More drag has the effect of "pulling back" on that wing, and thus making it slower than the other side -- resulting in adverse yaw. This effect is mainly predominant at low speeds. Wing you increase the camber of an airfoil, in some cases, you may also get an increase in profile drag (due to the larger "frontal shape" of the wing/airfoil. I hope this explanation was more clear.
