World Models puts out some of thr higher quality ARF planes on thr market. Some of the hardware you may was want to substitute for du-Bro or oyher bane brand stuff but for thr most part it is all usuable. The 91 will do just fine and give you good speed and plenty of power for aerbatics. I have built 2 of threse plane and would not hestate to buy another, as a matter of fact I will buy 1 this summer. It flys good and honest and has very little up stall if not to tail heavy.

Put it together and go have fun!!!!!!!!!!
