Never say "Trashed", You will love this plane.
Keep the engines close to the fuse. Suggest center of engines at 5.75". If you have good .40's, suggest 11x5 props for more thrust than speed. If really good .40's can go to 12x4, but must increase distance from fuse to compensate to 6.125 or 6.25" to clear props.
Make sure the wing has vertical sheeting between the spars, as the wing loading is going up. Vertical grain also on the sheeting.
Suggest keep engines upright for easy and safe starting. If you mount sideways, don't forget that one of the engines is near the fuse and glow plug connection must be considered.
Consider to enlarge the rudder surfaces to aid in control if the Unthinkable happens and one engine quits.
If you decide to not lengthen the wing, consider the wing plates I discussed earlier for more lift.....it also helps with knife edge.
We are all friends here and hope it stays that way.
When you finish..please send pictures.......uh before the first flight...tee hee......Sorry!!!
Remeber and burn into your brain the vertical test for engine stability!!! EVERY FLIGHT!!!
YOU decide how the plane flies and for all in this forum, let us know.
Best Of Luck.
