I'm starting to tune my engines myself now, i understand the basic concepts and all that. As of now i have my engine running cool, its holding headspeed at full collective and is performing better than ever. I've been adjusting the high end needle, and now it's time to start the mid range needle. Right now it's holding up great, its running at 1950 headspeed with the Algin pipe at an 8.20 gear ratio, when i do tic tocs it starts to bog, so i need to be really easy on the collective, i have great collective management, so i can figure it's not a problem on my end.
My set up:
Trex 700 8.20 gear ratio
O.S 91 HZ Non PS, Align 90 pipe
Radix 690 blades weighing in at 185 grams
Rotor tech paddles at 20 grams The airfoil is very thin but the paddle is longer than most others.
I'm going to try the Radix paddles tommorow to see if its the paddles that are causing the problem, but as of now any tuning tips would be great.
