hey,

I am just finishing up my giant Corsair and was about to mount the engine. But How ?
Can I mount that 3W-75 directly to the firewall which has been glassed extensively ? I was planning to
use thin grommets at the root to supress maybe some vibration.

Please let me know if this is a good way or not.

thanks

The instuction sheet for my 3w-75 suggests using a engine mount between the firewall and engine. I don't know if they would be available in Turkey but, the two 3w importers here in the US sell them. The mount is a 6mm plate with holes loacated for more secure and conveinient mounting of your engine. I would mount this engine very solidly to that firewall, no rubber grommets in there. Balance your prop carefully and vibration will be minimal.

Use standoffs to keep the engine solid and away from the firewall for better cooling also
