I have the GP Cap and I absolutly love it. I have an OS 70 Surpass II with 13X6 prop and I get nearly unlimited vertical. It will climb forever but it will loose some speed. Most of the guys at the field were impressed when I take off and point it straight up just after takeoff. Then go into a nice hammerhead to complete the sequence. It has the potential to torque roll but the most I have gotten is 3/4 of a turn before my stupid fingers loose it. It is an easy building plane and EXCELLENT flyer. You may consider a FG Cowl from stans for it. I have the stock one but it was a pain to get completed and it has developed a few cracks. I repaired them but just go with a FG one to start. With my motor combo the only thing I changed was the battery location. It is now right next to the servos. I did tail mount the rudder servo.

Mine weighs out at 5.5 LBS WET

My avitar is of mine. Let me know if you want more pics.
