I have a Sig Midstar with an OS 40. I'm looking to convert it to electric. I don't need mega speed as I prefer light aerobatics. I'd really appreciate any suggestions on a suitable motor/esc/battery layout.

From what I've read, brushless is the way to go, along with LiPo batteries. That's pricey! I'm probably going to invest in the brushless motor but with NiMH batteries for now.

I'm not sure what the extra weight of the NiMH batteries will do to the equation (in terms of motor size, prop size, speed, flight time, etc).

Anybody tried converting a Midstar or have an opinion on how to proceed?
