Hey Doug, I posted that over four months ago! Since then, I bought a Quickdraw Pioneer 29. It screams! My best speed so far is 76 MPH w/ my Backlash. I'm still experimenting w/ props and setup. I took my TS lower end and built a new motor w/ it. I'm testing it still. This is what it has: Trevor Simpson reed bottom end, RCMK K-30 top end, A stock stroke full circle stuffed crank w/ a +5mm con rod,( 5mm base plate) and a QD modded WYK33 carb. Same carb thats on my Pioneer 29. I took it out for a run, but sheared a flywheel key and went home! I think it will be a strong motor. I'll keep you posted. John
