Howard, This plane deserves a good 4-stroke. My personal rule is - "2-strokes for speed, 4-strokes for torque". I'm sure many will dissagree but you decide. Mike, I too, have discovered a hairline crack on the leading front edge of LG. I had one kinda hard, bouncey landing. Not really noticable but there just the same. If you guys want a real "eye-ball" popper, price check some of the replacement parts for this plane........ WAY OVER-PRICED ! I always buy a spare set of pants and a cowl but this time........ MM
