RE: GWS P-51 Mustang (Robbe Mustang)
I would appreciate some help if you can spare the time.
I fly the larger IC powered hanger 9 Mustang, SU 31 and others. I have purchased a built up Robbe Mustang complete.
Ihave tried a couple of hand launches but it just didn't pull away. Landed abruptly! (or controlled crash?!)
I have flown glow Club 20 pylon racers years ago similar in size only no probs here.
The motor is a race 600, protech pro 35 ESC, Ripmax Sanyo 8.4V 2000mAh 7 cell pack and a "slimprop"8x4 propeller.
After the hand launch I tried to keep level flight to pick up airspeed to no effect.
I was going to change the prop to a 9x6.
Your advice would be appreciated.
