RE: twin seamaster engine size?
Thanks for all the info. I am using the asp 25's because they are only 37.00 each. Hope I get 2 that run fairly reliable. They are the same thing as a magnum 25 xl not the xls. most of the reviews of the xl seemed ok, the xls was super. The thrust line of the 25's will be about 2.5" to 3" lower than of the engine pod design. I am hoping that it will fly well. I have already put the engine pod suports in the fuse before I decided to go with twins so if I build another wing, I could still put one big engine on it. Will 1/8" birch ply for nacelle sides with 3/16" firewall be strong enough to hold a 25 engine? I will glue each nacelle side to a rib side and the main spars (top and bottom) will go through the light ply.
