I have a completed XE2 powered Combat Wing. I have flown it once - until the prop came off! The problem comes with the launch. I hand launched it with the motor off while someone else had the transmitter. They got it under control and then powered the motor. I couldn't figure out how to launch with the motor running without endangering my hand [

]
I also couldn't figure out how one person can launch and control too.
What is the secret [:@]
How does one hold the 'wing' to hand launch??
Any advice will be appreciated.
Phil
