Just ordered one. Will use a Saito 91. Any tips on building it?

If using the Saito 91. Put the throttle servo up front. You will need to use a band saw or scroll saw and cut some area out of the ply. I just put a saito 91 in my first one and it is way tail heavy. But I also have the engine mounted rearward. Might be wise to bend the landing gear out a bit, so it doesn't want to tip so easy in a little wind. Other than that it is a breze to build and way fun to fly...........

Do you think a Saito 82 is too small for the 60?

I don't think the .82 would be a problem. My saito 91 hovers at under half throttle or less. These mojo's build really lite.

Just put the servo up front in the ply. area.

If you have the time. I used white PVA glue to join the the fus parts which paid dividends with a "nose in" only damage was a broken prop and covering tears. It came out tail heavy so lighten the rear if possible.
