I was just seeking advice for an engine for this plane. I would like to use a YS63 if it will be sufficient to do most patterns. Any help would be greatly appreciated.

Yes, a YS63 will be fine for the plane. I've had a Magnum 70FS in one, but felt it slightly underpowered. An OS 50 SXH in another, which was a very good match. The YS will be closer to the OS 50, than the Mag 70FS.

What do you think about the Saito 82 for the plane?

A Saito .82 should work fine as well. One of the pattern pilots at our club has a Spot On .50 ARF with the YS .63 in it, and it's a great practice plane and a nice looking model.

I stuffed a saito 100 under the cowl and its awesome. very accurate tracking in the air.

It sounds amazing.
How did you fit it there?
Do you have pictures?

hello im finished with the build on the spot on 50 and im wondering if the model could hover with a OS 81fs-a or a Saito fa82 engine???
