Engine Mount
 

I have a You Can Do airplane that’s almost complete. I decided to put another engine in the mount that already has the holes drill. They are overlapping each other that will make the hold much bigger the normal. Is there a fix for this or do I have to by another mount?

Thanks,

a typical nylon mount is about 5$ for a YCD its a cheap replacement part

drilling over sized holes in the nylon mounts weaken them quite a bit save your self the agony of a broken mount and just get a new one

I think Tim is correct...I'd get a new mount

Then if the new mount's firewall hole position differs from the original mount, remove or drill out the existing blind nuts, and epoxy in a "plug" made from a standard wood dowel.

Make sure the plug sits level with the firewall back and front... I normally make the front a bit longer and work the plug into position so it sits flush with the back of the firewall.
Once the epoxy dries I'll use a Dremel sanding wheel to make the front of the plug even with the firewall.... once done you can drill new holes as needed.

The plane came with a GP Adjustable mount. There are 5 different sizes.

The dimensions are listed in the tech notes. If you buy the same size that came with the plane you will not need to redrill the firewall.
