I've got one myself! Been told that if you take out the muffler baffle, switch to a 2 blade 10x6 or 11x5, and lose the flywheel it should scream. Now remember, if you take that flywheel off it is a significant CG change. It will move aft making the plane more unstable compared to what your used too. It will still be stable, but might float more on landings, drop a wing on stall, and be more "twitchy" on the elevator. Dont forget you'll have to get a new spinner too!! Hope this helps. I wll be looking forward to your flight report after the mods as I plan to do this soon!
