Using a gram scale and current meter to find the optimal pitch curve for best battery life on the Walkera Genius. About 20 seconds longer than typical.

Upgrade the 4#3A to brushless and saving weight and increasing flying time.
3 modifications:
Upgrade to brushless
Upgrade the FETs on the ESC for lower resistance
Go to linear servo for further weight reduction.
Weight went from 48.5g to 42.6g.

Did a series of test using a gram scale to find out the most efficient pitch and throttle curve for the stock V120D02. This should give the maximum battery life. See my webpage.
