I recently revisited something I was interested in as a kid which is these rc helicopters. Of course back then they were several hundred bucks, now you can get a large one for 40-100 if you know where to shop.
Anyhow, I've been modding the circuit boards, boosting power and modifying them however I can.
I've actually increased the mini's flight time per charge from roughly 4 to 15 minutes.
The two larger ones are outdoor models, but only the biggest one can really handle the wind at all.
Anyhow, was wondering if anyone else messed with rc stuff.
