ehirobo, I resolved my problem.Â* The issue was that the stock 10C battery that originally came with my 4G3 was not strong enough to power the main Walkera ESC, a Turbo Ace 91416 main motor, a Flea ESC, and a Turbo Ace 2.9g tail motor.Â* As soon as I switched to a 20C 1S lipo, my motor spun up normally.
I got the clue of using a 20C battery from the double brushless 4G3 that wowhobbies sells for $409.95.Â* It uses a main Walkera ESC, Turbo Ace 91416 main motor, tail Walkera ESC, and a Turbo Ace 2.9g tail motor.Â* More importantly, the kit includes four 20C batteries and one 10C battery.
When you say you have the double brushess 4G3, do you mean the version with the Walkera brushless main motor and the Turbo Ace 2g tail motor and two Walkera ESCs?Â* And you can fly it on a 10C battery?Â* How long a flight do you get?
How does it fly for you?Â* I have yet to fly my upgraded 4G3, as I am now trying to resolve a vibration/head shake problem.Â* One thing I do notice is that the 91416 main motor gets hot to the touch.
Thanks for your help.
