I have the seagull super decathlon 120 with a DLE 20 cc in it and I can tell you , it's a freakin rocket with unlimited vert. I take off at a really high angle of attack and climb out at only 1/4 throttle, so I think it may rip your firewall apart on the 90 size. But hey, if that's what your looking for, just sayin.post some vids if you do.
