I asked this in ARF and no answers yet so ill try here

1st plane.

Epic/VectorFlight 58" Extra 300
its 5.5 lbs with electronics, no engine
it was 7 lbs with the MDS on it

2nd plane.

Great Planes CAP 21.
its an older kit. Its 4lbs empty no electronics or engine on it


I have a Saito 80, will it work and fly any of these with any authority?
