Ok my input. Watch your wieght!!!!!!!. I HAD a saito 91(14x4), 2300 NIMH battery and all stock servo's and the thing snaped BAD 2 times. I crashed and ordered parts. After last crash I went back to a magnum 52 (12.25x3.75)and put a 9g servo, under the cowling for the throttel and stock battery . Also took off the wheel pants. Put one servo in tail for rudder and 3001 on elivator in normal spot. Battery is behind the tank. Also conected the elivator's -- with carbon rod I had. It still has the dual control going back to. (that I do not like.) It made its first landing last week like this. Flew a lot better. It does knife edge good no great- superb. I did one hard loop and it did seem to roll a little bit but far from a snap. I have installed a Hitec 225BB on the elivator. To save some more wieght. But I do not like the way it centers the elivator. The hitec's that I have had new and used have all centered like crude. If there is a mod to make them center better email me. I will fly it like this. Hope it makes it back in one piece. Just watch that weight. I did not like the saito 91 to heavy and to much power. This wing area is small. Also did not use the yellow man holder thing. The virtical is great with this setup. If you want a 3d plane buy something else to over power. This thing does fly good. That saito 82 is light. I would put a smaller prop on it to check it out. and a small servo on throttel. hope this helps. [email protected]
