Nice to see Motion and Black Horse getting into the giant scale 3D market but recommending that particular servo for an airplane like this is asking for trouble. 133oz-in is not even close to sufficient for this size and type of airplane. There will be severe blowback with any large deflections but what people don’t think about is that even if sport flying, the risk of flutter with these large surfaces and low torque servos is very high. The generally accepted torque requirement for planes this size is approximately 400 oz-in. You can get by with less but you will likely have some blowback in any high energy maneuvers. YMMV but I would absolutely not use that servo in a plane like this.

I would also like to see some interior pics as well!
