This past week I added a little more setback. Went fron 8.5 to 10.5 inchs, Let me tell ya, It made one heck of a positive change. Still running the Turbo TXP ot-4 30 pitch which is stock (except for leading edge being almost razor sharp) she jumped up to 85.1 mph @6200 rpm with out a problem, handling was like a dream compared to how it did with the 8.5 inch setback. Next week I will run the Mazco R.E.
