I have the GP ARF cub with a Saito 72 on it and it’s a good match. It fly’s great and has a good sound. I got the engine used in like new condition for $115. I’m using an AR7000 and DS821. If your plane is the ARF and has the CA type hinges for the wing strut mount don’t use them they will break for sure. I replaced them with nylon ones and have no problems now.
