my wife just picked up a twinstar ARF for $40.00. the plane comes with two 400 brushed motors and nothing else, I was wondering what amp speed controller I should install. I donated her my Hitec Lazer4 radio out of my Magister that I plan on installing in the Twinstar. I'll have to buy everything else. any suggestions? also this will be her first aileron plane, are the stock motors going to fly the plane good enough? it doesn't have to be fast just enough power so you don't have to fly at full throttle all the time to keep it level.

I would go to the electric forum, they would have some better information on that for you.

I hope that is not your first plane, pretty tough one to start on even if the price was right

Sport - get something in the region of 30A would be nice. Each motor will pull around 8A-10A when you are cruising about. The plane is nice to fly ... not very floaty for a beginner but if you have stick time on a sim you may survive. She is nice to cruise about turning with the rudder, doing your best to fly scale like. It flies ok with a 2 cell lipo set up. I would say fly at around 60% throttle. Knock yourself out ok!

I'm pretty sure you'll need a speed controller for each of those motors. and it will be best to also have a battery for each motor.
Granted, I don't have much experience with electrics, but I have 3 or 4 brushless setups (none of which are multi's). Maybe someone else can answer better, but I bet you end up buying two separate controllers and two batteries.

If you use the motors in the kit, you won't need two ESC's. These are Speed 400 brushed motors. I used a 30 AMP brushed ESC for mine. It was a grey one, the Mark I. I used 7 and 8 cell battery packs, one at a time, usually 1300 to 2400MAH, either NiCd or NIMh. I had it for over four years and destroyed it last year. It just stopped responding to the radio. I'm tempted to buy a Mark II, the new white one, but so far I have too many projects. It's a great flying plane and nothing beats the "gee Whiz" effect of a twin. I'll be glad to answer any questions you have.

thanks for the reply, I'm glad to hear the plane is a good one. I haven't started the build yet but I'm sure I'll have some more questions once we get in to it.

It calls for 1 30 amp and a 8 Cell 9.6V 3600 mAh NiMH Pack.


chopper

on mine ive got a cirrus 4ch Rx, 30 amp ESC and 2C 4300mah LiPo battery

one ESC will do, you can go for two smaller ones but why complicate things with the wiring?

How long a flight do you get with that huge battery?
