I've recently bought a second hand Der Jet Cougar and have installed a Jetcat P140 RXI B. Can someone please assist me with the correct CG location? I'm also keen to hear how much flap and what elevator movement/mix is required.

Thanks, Neil

Sorry I never found a manual, but balance is not critical and since the set up is basically the same it won't have moved far. The valves are pump were above the 160SX, so much the same as your 140. Movements as I said you need as much elevator and aileron as you can get, it will be obvious from servo slots the limit.
Flap I had around 60mm at the flap aileron joint, only 25mm on fuselage flap. Up mixed with landing flap was around 9mm.

This is a super plane, looks great in the air and on the ground. CG and control throws worked perfectly.
