Tiger 60 ARF motor mount........
 

I found out my O.S. 91 Surpass 4-stroke has the same mounting holes as the OS 61 had so I want to install the OS .91 4-stroke in place of my OS 61 2-stroke on my Tiger 60 ARF.

My question is....has anyone mounted an OS 91 4-stroke on the Tiger 60 ARF and still used the mounts that the Tiger 60 ARF came with?

Thanks

G'day Mate,
Just stick the 91 in the mount & see if it fits!

The 91 4 stroke fits in the holes great in the smaller mount...same holes as the 61 2 stroke I had on it. Just wondering if that mount will handle the 91 4 stroke.

G'day Mate,
They have about the same power output, I would give it a try, bolt it on to the mount then mount the engine mount on a piece of wood, & see if it flexes too much, that's better than drilling holes in your plane.

I installed the 4 stroke to the engine mount.

I'll know this summer if it's going to handle the mount or not.

thanks
