I haven't flown mine yet, but I can give you some hints on the building of it. Do whatever you can to keep the tail light, as you are going to have to add significant weight to the nose to get the CG right. Move the battery and all components as far forward as possible. I would consider going with a big four cycle for weight reasons, and a 1.20 wouldn't be a bad idea. This plane is really a .90 size in my opinion. I started out with a Saito .80 on mine, but went to a 1.00 before I even started it.
