I have one and have not been too impressed. I have a OS .26 in it and can tell you it is very underpowered. I'd put a 40 4 stroke or 32 2 stoke. It will fly decent when in the air, but take offs are long and with this short coupled airframe it is a handfull on the ground. Landing is challenging not to nose into the dirt. Keep the tail planted on landing the best you can. You can forget touch and goes. Cant get it to do much with the OS, but a bigger engine would probably make it shine. Frame is built well and It really looks good. I have moth-balled it to the wall "looks nice" catagory.
