I wouldn't trade my GP Cap for any other one. While tuning the engine on Sunday my prop broke at about 8000 rpm. The vibration before I could shut it down was scary. Now that I've gone through it completely not one glue joint came loose, not one piece of wood cracked. Broke a gear in my elevator servo too. I was really impressed that nothing came loose as far as glue joints go. Gonna try a 16X10 3 blade for a flight or two and compare it to the 17X13 2 blade. Anyone know how a 3 blade works on the Cap? Anyone try em up there in Washington Al? By the way the one day no one brings the video camera I got a beautiful upright flat spin back through my smoke trail.
