twin deltas
Phiily baby,yep,I played around with mid engine deltas last year.They are the obvious solution to virtually every issue using one or more engines,especially cg.Trouble is you lose a massive amount of thrust working the prop in a slot-put the scales on it and you'll see what I mean.Worse than that I had two prop breakages for no apparant reason,but only when I started using higher rpms.Props in slots are pants.I get massive amounts more performance keeping the props external-especially with two engines.Regards Marc Sommer.
