I need help setting up my H-9 Cap. I'm using an OS 160FX for power, & Hitech 5625 digital servos. The question I have is where does the CG need to be for best flight performance? Thanks For all the help, if you have any advice please feel free to share it, need all the help I can get. Thanks

I have this exact airplane with the O.S. 160 in it and JR 8411 digital servos and I have done a whole lot of experimenting with it.

At first I had my receiver and battery pack(1100 ma) mounted in front of the servos. With the engine as far out on the mount as the instructions states this made the plane a little nose heavy and made it hard to land and did not allow for great 3d performance.

I then moved them back a little by managing to get them underneath the servo tray and this makes the balance right on the money, landing was no longer a problem and 3d was better but still not like it should be.

I later ellected to add 1/2 an ounce to the tale of the airplane and this gave the airplane 3d performance to the max. The 160 is the perfect power plant allowing for smooth torque rolls and just enough power to pull out of them smoothly

Aerobat82 , did you have two elevator servos in the tail? This is how my plane is set up. How much did your plane weigh? Thanks for the info, Rob
