I know my .15 will pull about 16500 with a 7x6, the only thing close is a zinger 8x6. I thought I would cut it down to 7. honestly I didn't even think about the fuel tank location(being infront of the engine) and the effect it would have on tuning. glad you brought that up
Sportrider - when in doubt, check APC first:

But as CP says, it is a bit much load for anything but a strong .15. Zinger has a 7-4 wood, but 4 pitch is only
fast at >>20k. But on a sport .15 with the resultant rpm the airspeed will be spritely for a small aircraft, just not fast if'n you know what I mean. Imagine an 8" pitch prop at high four stroke rpm if that helps visualize.
