problem with ys 120 end muffler Funtech

[mastermide]

hi, I have a problem with the silencer, I muffler that after several flights you spring for vibration, use the gasket between the engine and the joint, what should I do? I have to use the seal for high temperature in place of the gasket ?

Most people using YS motors do not use a gasket between the motor and the muffler.

I do not use a gasket between my YS 120SR-X and Hatori pipe.

But, you may benefit from using a high temperature RTV as a "thread lock" on the muffler bolts / screws.

In the US, we can buy this product: http://www.all-spec.com/products/811...FY9hfgodw9sEsQ

That is an example. Maybe there is a similar product in Italy / EU

Having the muffler coming loose because of vibes means you have to much vibes you need to chase down. First cause with the YS120SR is the engine itself if you run it too rich.

I am running YS120SR engines on both my 700 birds and no issues using the thick 'gasket (mounting plate)' provided with the Funtech pipe without any sealant.
