Hi Diablo Kid,
The extra 300 put out by Hanger is a Seagull Extra 300 ARF. I think it takes a 46 size motor, and 6 servo's
Im just finishing up on the Seagull Edge 540 and getting ready for the maiden flight.
The kits are very well constructed, and come with everything but the engine & servo's. The covering is Ultracoat and looks very sharp.
The only problem some people are having is with the wing folding. Posobly due to a week main spare or when the covering is applied, there cutting into the wing sheeting and weakening the wing. All in all my Seagull Edge 540 went together very quickly and not very time consuming.
Check out the threads on the Seagull Edge 540 her on RCU
