As for which motor from hobbycity...no clue. I *LOVE* the ARC motors...faster than greased lightning...and can take serious power abuse.

I must have gotten a bad one then. My ARC 28-37-2 went bad after about 20 flights. With the prop I had on it it was only at 40Amps static at WOT.

I always hear that you get what you pay for, that wasn't true at all with the ARC motor. I'm just going to stick with the cheap $20 motors. At least when they burn up it doesn't hurt the wallet quite as bad.

Zeta30,

Find out about ARC repair policy and cost.

Reputable companies always have a repair policy. If you can get your ARC repaired for same $20 or little more and that leaves you with a better motor than a $20 motor...you should do it.

Only issue will be the waiting time.

Zeta, did you contact Dave about your ARC motor? If not, you should try and see if he can help you out. The ARCs have to be some of the best I have run for their price. Have used the 2.5 short and 1.5 long can and am pretty amazed at the abuse they take. The long can 1.5 will take a lot of abuse with a 4S lipo and 80 amps. The Ritewing guys are slammin these motors and they take it no problem.

Not sure what to say to this....if properly cooled....this motor can go 6S or more. I've dozens of flights on this motor without issue. My ONLY issue is the shaft...I don't think it's tempered....so it bends (IMHO) too easily, but lightflight will sell you a replacement for 1/2 off...so I'm not complaining. Outside of the shaft issue....I've abused the h3ll out of this motor, and still love it.

What would be faster, if I had to choose between these 2 motors? Mega 16/15/3 or 4? powered with 3s 2200 25c. I believe the '3' with 4.7x4.7 but not sure. I can go up to 40A.

I am using the 16/15/3 in a very fast pylon race type model and using a 3s LiPo with an APC 5"x5" only draws 37 Amps (bench measurement) and gives just over 400 Watts (in) of power. These motors are very good quality and can be pushed further than what the manufacturer recommends and I think the '3' could easily cope with a 5.5"x5.5" for short bursts.

I sent an e-mail off to lightflight this morning, will wait and see what they say.

For now I'm using a back up motor, a HeliMax inrunner I had in an old helicopter.

Thanks. So it is as I have thought. Well, for now I'll try a Ray Inrunner with 2200 kv - should be something similar to 16/15/4 and see what will happen. If it is not enough for my FJ, than I have a ''copy'' of Gebhard Denon which should be happy to get this motor.

With a slow outrunner engine it is more a parkflyer / mini glider. I will be building a new one, with a ''faster'' airfoil and prepared for mounting the motor behind the firewall.

To anyone that is looking to make their funjet HAUL, i would suggest you look at this page

http://www.neumotors.com/2008/store/page10/page10.html

Towards the bottom is a neu 1112-2.5D which would make any funjet RIP! Its a 93% efficient motor! And its there for 50 bucks instead of the listed 135!!!! Just a thought for all those that want to go fast. This motor would be good on 4s or 5s and probably 80 amps or more in bursts!
