I have a GP Extra 300S .60 and it doesn't 3D very well mainly because it's a little heavy at 8lbs 3oz. I started with a GMS76 which would barely hover it. Then I moved to an OS91 FS which was little improvement over the GMS76. Now I am swapping that engine for a Webra 120 to see how it will perform. Hopefully I'll get to fly it this weekend with the Webra to see how that improves it. One thing it really needs for 3D is a much larger tail section.

I'd say if your looking to do some serious 3D this plane isn't the best one for it... Just my opinion...
