I got a trex 450, pitch goes around -11, 0 , 11, cyclic up to 6 degree expo 35 for cyclic to make it fly straight up to finishing line, motor scorpion brushless 2221-6 11T and 2221-8 14T scorpion commander 60A esc.

The setup for esc is governer mode 100% flat throttle for 2221-8 and i only go 90% flat for 2221-6.

Transmitter dx7, Throttle hold on the start, center stick 0 pitch switch to idle up2 and connect battery, 15sec soft start.

For tail HG5000 with hs5084, gyro gain 75%

Then jump ur heli to forward flight like hell

IF ANY1 GOT AN IDEA HOW TO MAKE IT MORE BETTER PLEASE REPLY!!!!!

MAYBE WITH BETTER BRUSHLESS MOTOR OR ESC COMBINATION

You can make the heli lighter or use longer blades. But you's have to change the gearing a bit so that it will have enough torque.

You can get more pitch on the main blades by modifying the washout base. Do a search on here, I know it's been done. I think you can get up to like 14 degrees of pitch. Also, if you just want FF speed, adjust your linkages to max out the positive pitch and just ignore the negative side. You won't have equal throw but if speed is your only focus, who cares?

...now where was I, dh/dt = BS-dx/dt
I will fly you forever... till earth do us part
