[RCSE] LMR motor for Pike Superior
I am setting up a Pike Superior for F5J next season and am looking for some suggestions as to what drivetrain to put in it. I have in my collection a couple of Aveox motors that I have never used: An F12LMR (10-16 cells) and F7LMR (7-10 cells). So far, my experience with unlimited F5J planes is with my molded E- Graphite, which uses a Hacker B50S LMR (7-10 cell). I've been running it on 10 cell GP2200 packs and it gives the Graphite a vertical climb. I'd like the same sort of climb with this new Pike. Few questions for you F5J experts out there: 1) I want to run this plane on 10 cells so as to keep the weight down. Am I better off running the F12LMR or the F7LMR with 10 cells? What are the pros and cons? 2) Will I be better off simply putting a tried and true Hacker B50SLMR in this plane? 3) In addition to the three large wires, the Aveox motors have a five- wire connector that apparently connects only to the Aveox controllers. But all other controllers I've seen have only the three large wires. What are the 5 small wires for? And can an Aveox motor that has them be controlled by a Jeti or other brushless controller? Thanks for any suggestions and advice! --Jim Laurel Seattle Area Soaring Society RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] LMR motor for Pike Superior
Jim I cannot answer the which powertrain question due to little knowledge but can answer the wire problem.In the early days of brushless controllers they needed a sensor in the motod to relate therotor position for motor control hence the 5 wires.With the later controllers these are not required this data is picked up by the micro from I believethe current waveform.You can run the motors on a modern controller no prob (I do an Aveoxon a Jeti controller) just ignore the sensor wires and tie them neatly in the nose area.RegardsDave (uk) To help you stay safe and secure online, we've developed the all new Yahoo!

Unless it is too light, then by all means the bigger motor - generally, bigger motor = slightly higher efficiency! But higher weight, lower climb, so it isn't sure you win with a bigger motor!

Re: [RCSE] LMR motor for Pike Superior
Hi Jim, Sounds like a neat project. I have recently converted an Artemis to 10 cell and it is a lot of fun. I use an Aveox F10LMR in it with 10 GP2200s. That's all that will fit! You should consider trying out the various combinations in MotoCalc. It's a great program that lets you test drive your combinations before you buy. I think you will find that the Hacker motors are lighter for the same output as the Aveox. Due to their better magnet design they can spin faster, and using the higher ratio gearboxes, spin a larger prop than the Aveox. Larger prop disc results in moving more air = more thrust. You will want to keep the setup as light as possible for best sailplane performance. The added weight will also make it more challenging to spot land the ship. It won't be the same as landing the TD ships. A landing that would be normal for a TD ship DID result in cracked fuse on the Artemis due to the added mass. All that said, I too had an F10 and an F12 hanging on the wall when I went to convert the Artemis. I found the F10 to be the better option for me. Commercial plug warning -- If you are in the market for a new speed control I'd like to suggest a Castle P-80 for this project. It is a sensorless design, as are all controllers these days. They work, and they have great support both for setup and for troubleshooting should you have any difficulties. I think they are priced comparably to the Jetis, but I'd better find out for sure... There are a number of reasons that the P80 is a good choice, but in sum, it's very flexible and options may be selected in the programming that will help you have more fun and less trouble from your ship. Yes, I do have a relationship with Castle. I also have some LMR knowledge... Good luck, any questions, please don't hesitate to contact me.

Re: [RCSE] Re: LMR motor for Pike Superior
Hmm, need to reply to this one too. 1. I personally think that the BEC idea for a ship this size is a bad, bad, idea. BECs generally are not designed to serve power for more than 3 or 4 servos. Less if using digitals or micros. I trust that your Pike would have more than that. Also, BECs are part of the motor controller. Should something nasty happen to the controller, you simply lose the entire ship in a spectacular and agonizing manner. I found that there was no way to adequately balance my Artemis without using the RX pack as balance weight in the tailboom (about 16 inches behind the wing!) A receiver pack is the safest way to go. Weight is important, but reliability is much more important to me. 2. LI-ION or Li-Poly are really cool. Really expensive too. Not real small in form factor. They may not fit into your ship. Not as cost effective as the GP2200 or similar. Also, they don't come out nice and warm for those cold days :) High amps are hard to come by on those things, you will likely be drawing 60 or 70 + with the Aveox. Don't want to do more if you want to use it for a while.

I've gotten that response. It's not typical, but I've gotten it. A better angle is to also point out that it would probably crash their plane as well. I've also seen these discussions get somewhat hostile. Telling somebody that they _can't_ fly in the city park near the AMA field tends to not go over well, especially when people start citing laws and rules that either don't exist (AMA club fields do not get `special rights' to the R/C band) or don't apply (AMA rules don't apply to non-members.) And the last thing you want to do is piss somebody off -- they can cause trouble for your club (call in noise complaints for powered clubs, get the local parks department involved, etc.) or could even go around deliberately interfering with the channels that are in use. I've not personally seen it happen (at least not where it could be proven), but I've heard of it ... | ME: Well you could join our club and enjoy frequency control and the | shared knowledge of 100 fellow pilots. Around here, the powered plane club has very little to offer your typical park flier. Sure, it's a nice field, but there's all sorts of rules that the park flier doesn't like (sure, they're good rules, but that's not the perception) and the other fliers really tend to look down on his `little toy plane'. (If it's one of the $150 jobs. If it's a more expensive plane, with real gear, then people aren't so dismissive.) The local soaring club has a better attitude (since most of the members have a park flier or two), but still, they don't have that much to offer. At least not for the price, at least not what the park flier actually wants. | PFG: How much? | ME: Our club is only $20 a year, but of course you would have to | become an AMA member for $60 a year. You're certainly right about that -- it's quite a deal breaker. Many clubs will even let the $20 slide ... but the $60 generally can't be ignored. Nobody wants to pay $100/year just to fly their plane that they got for less than $100. Especially to fly it with a bunch of people that really aren't that nice (and I've heard this, over and over, from people that I've talked to with park fliers), at a field that's even further than the local park, with all sorts of `silly' rules. (I could talk about `not being nice' to the park flier people at some length, and I've even brought the issue up at meetings of the local powered club, but ultimately there's a very strong feeling of `entitlement' and `superiority' that tends to run people off very quickly. But that's where I'll leave that issue for now.) Really, the only real solution to the frequency control problem with park fliers is spread spectrum. And it looks like the first installment (which isn't perfect, but it looks like a really good first shot) is due out in about a month, called the DX6. (It's not perfect because it's not sutiable for those $2000 planes, not yet, and you can't control the radio gear that the park fliers flying nearby will use. But hopefully soon they'll come out with the next version.) -- Doug McLaren, [EMAIL PROTECTED] RCSE-List facilities provided by Model Airplane News.

It's smoother than a Hacker and I can talk to the people who built it on the phone. I had some range issues with a UBEC too. Now that I have a little 4 cell AAA pack in there the worry of motive pack failure is gone as are the range issues. If a cell goes bad in the motive pack or something else it's still a glider!

Re: [RCSE] Re: Soaring V1 #6696: LMR motor for Pike Superior
This could go on forever. Proper cycling and observation of cells will indicate whether they are to be trusted. However, using motor cells for RX has more mechanisms of failure due to the higher amp draw/heat/Motor/Controller failure/more joints to fail/etc. Could be something as stupid as the firewall coming unglued and jamming the motor/prop/ Similarly, more in the UBEC to fail too. It's up to the user. I'd go with simplicity, the weight savings are minimal, perhaps de minimis, in perspective of the size of ship that we are talking about. Over and out.

RE: [RCSE] Re: Soaring V1 #6696: LMR motor for Pike Superior
While I don't think anyone has a definitive answer to the question to BEC or not to BEC, the argument against a BEC is that the system drawing 100+ amps is much more likely to fail than the one drawing 1+ amps. Remember, we trust our unpowered gliders to those Rx packs all the time.

I am running a 1506 2D 6.71 gearbox on 10 GP 3300s with terrific results. 80 amps with an 18x10 prop in an electric Escape. It's smoother than a Hacker and I can talk to the people who built it on the phone. I had some range issues with a UBEC too. Now that I have a little 4 cell AAA pack in there the worry of motive pack failure is gone as are the range issues. If a cell goes bad in the motive pack or something else it's still a glider!

Rethinking, yes, of course! But one of those gizmos that replaces a rx battery saves a lot of weight. And yes, form factors when it comes to Li-Ion packs can make them impossible to use - but check around, there are many brands!
