Yes, the prop on my modified PBXL is a modified Zinger 10x4. I would not recommend full throttle on this one at any time. It screams straight up at half throttle The PBXL does not like speed, though was not designed for speed at all.
The UpRoar landing gear should work well.
Let me know how you make out.

P.S. Can you give me more information on the Swap meet in NC Jan? I may go. I have reservered a couple of tables at Perry, GA end of Feb.
