I have two of them, they are sweet flyers!!

One has an OS 91 surpass four stroke with 14 X 6 APC and flies great.
The other has a Saito 100 four stroke... WOW, unlimited vertical at 3/4 throttle!!!

I wish there cowlings and wheel pants were of better quality, mine are already cracking.

Do yourself a favor and glass the inside of the cowl before you mount it, you will be gla you did.
Also reinforce the wheel pants too. The parts look really good but won't last very long without the reinforcement.

And last but not least, prepare yourself for a thrill with the sticks!! And when you land, be sure not to try and slow it down too much, the wings are fully symetrical and will land a little faster than you may be used to. These extras fly straight and true and will track like they are on rails.

Good luck and have fun, they are great planes (note the pun)
