Just order the sig smith miniplane want to know which 4 cycle is better for that plane ?

light airplane, any .56 or better will fly it fine.

Mine came out tail heavy so I ended up using an OS 70FS and that cured the problem.

thanks gray beard i have annother ? do you put the motor mount the same way like they said in the building instructions for your OS70FS if hit is yes so i can start to build the fuselage.


hey sorry for my english

AN OS 48 or 70 would work. The Best is an Saito 56 although a saito 50 or 62 would work, I have had this model since original build in 1987. I started with a Saito 50 and wore it out and put on a os 70 and it felt nose heavy and just plain heavy. Now it has a Saito 56 black knight on it and it is fine. APC prop and 30 heli fuel and you can almost hover for 30 seconds.
