RE: Bob Cat Copy Falcon 120 Jet
My first Falcon weighed about 14.5 lbs. (approximately 6 kg.) with a Wren Supersport engine. It was pretty much in original configuration with Spring Air retracts and wire struts. I am now working on my second one which will be reinforced, repainted, recovered with Monokote, with heavier retracts and Prolink struts. I expect it to weigh about 7 kg.
Here are a few pictures of the installation in my first one. If you look back in this thread to about pages 22 - 25 there are detailed pictures of how I did the modifications.
