RE: Shorts Sky Van?
I have a plan here for a Skyvan for a pair of 049's or, more sensibly these days,
a couple of small electrics.
A friend built a free flight version which flew very well, he even had the ramp drop
& a cargo drop with a parachute via a timer. This was electric powered.
But, for me, there would be a lot of twin engine models I'd build before a Skyvan! - John.
