This may be some good tips. On my v3 after my tail rotor burned up after about an hour of flight, i bought the 10$ gws motor from tower it comes with 2 gws props that work just fine and same color as my orange cannopy. If u dont like the orange gws props u can black sharpy them, i do it all the time on my e planes with gws props and it doesnt rub off. Anyway, Some mods that i did to keep the tail cool is rotate the tail 180, flip the prop and revers the polarity so it blows back on itself, the tail is just warm now after a flight.You have to sand paper the shaft and ca the prop on or it will pull off, but u can still pull it off with pliers if need be to replace the prop. I allso bought an extra main motor heatsink to cover the rest of the motor "had to grind it down to fit" main motor is not as hot now. I swear my axe smelled like burning electonics with the stock setup after a flight. I also moved the pushrods in 1 hole and that made it alot less squarly. The axe is not rock solid like larger beter quality heli's but it has made me alot beter pilot. Going to my 450 after flying my axe seems like a co-axle. I love flying my cpv3, i think because im not as nervous with it as i am with my more $ 450 clone.
