I apparently did use enough thread locker on my engine mount bolts and as a result the bolts came loose along with the half inch aluminum standoffs to my Fuji 43. I stopped by the hardware store and the only spacers they had available were half inch nylon spacers. I am sure this was covered in many threads but I wanted to try to fly today and wanted to see of someone recalled if I could use nylon replacements on one side and retain the aluminum one one the other side.

Yes, but better to use the same type of material for all of them. They can be wood, metal, nylon, carbon, or whatever, as long as they are hard enough not to compress when the bolts are tightened.

Tired old man is right...I think most people use wooden dowels...right MR Tired? Best Regards capt,n

I have seen many use wood. I for one never found the courage to do that. I rather use metal, and wide washers where they meet the firewall in order to distribute the load. Even then, the firewall flexing worries me.
OTOH, this flexing eliminates the need for iso mounts.

I keep a closet pole around the garage and i go to wacking when I need a spacer

Closet pole, huh? I buy 1" - 1.5" pine dowel. Saturate the standoffs with CA glue after they're finished. Keeps them from soaking up gas/oil. I feel that large diameter wood standoffs soak up vibration and torsional forces better than narrow metal ones. Cheap too!

The nylon spacers will get hot from engine vibration, and engine heat. That will cause rapid wear and failure. They will colapse with time also. I would never use them in a stand off mount. Wood dowels are cheap cheap cheap. Your 50cc size engine will do fine with a 3/4" dia. maple dowel, or use 1" if you prefere.
If you need short spacers like about 1" long look for aluminum cable swags. A good hardware store will have them.

Thanks for the feedback. I went out and purchased a 1 inch oak dowel and made new spacers. Again that you all for your suggestions!!

You're welcome.

Personally I'm rather impressed that you were creative and made your own new stand offs rather than order a set of new metal ones. The "hobby" side of this isn't dead afterall

Bravo!

Hay, some of us are still modelers, not just assemblers!

Reminds me of this past weekend. A guy looked in my plane and asked me if you had to set it up that way. Of course I said you don't have to do anything but that is the way I like[/u] to set them up.

Goodonya! Don't forget to fuel-proof them.
