Justa had three flights with the GP Gee Bee and what a beautiful plane it is. I'm running an OS Max 1.20 III with a 15X6 prop...same setup as the RCU review on this plane. I found that the plane needed full throttle all the time and I feel that I could use either a larger prop or more pitch. Anybody out there running this setup....the engine specs calls for 15X8-10, or 16-18X6.

BTW, this is the hardest plane I've ever landed. One out of the three landings was perfect...the other two were pretty hard....thank god for Robostruts....All landings were on paved strip....wish I had grass.
