Guy I am new to electric planes. I have been flying glow powered planes for few years but recently i decided to try an electric plane. I have a 40 size trainer that i want to convert to electric. My question is what size of motor and ESC would i need. I am looking for decent quality nothing fancy. Anything that would get me decent speed and performance nothing over the top. I have some 3s 2200 batteries if that info is useful. Going to buy it from Hobby King (as they ship to Pakistan) so any links from that website would be nice.
Thanks in advance for any help in this matter.

Go to post 3 about sizing requirements.

Also, here's a good website: http://www.maxxprod.com/mpi/mpi-264.html

If you're running a 40 sized trainer, you might need something like combo 46A

You can convert nitros to electric, but you're better off buying purpose built electric airframes. The nitro airframes are more rugged (and thus heavier) than they need to be for electric.

If you're just getting started in electrics, I'd suggest getting a foam park flyer of some sort. The smaller park flyers are cheaper to equip, and foam airframes are super easy to repair. If you have some 3S 2200mAh packs, then the park flyer sized planes would be perfect.

To fly larger planes with those packs, you'll have to double them up in series or parallel, since the larger planes require more power.

A 480 watt and a 50amp ESC will work nicley with a 2000mAh 3S battery. If you are going to shop HK, go with Turnigy.
