My buddy and I disagree about using a gasket or gasket seal when attaching the header to the engine. I say, yes you should use either a gasket or red rtv, he says it doesnt matter as the header fits so tightly as it is. What do you guys recommend, or what is you opinion?

I am finishing up my trex 700 with YS motor and hatori pipe and I am trying to figure out the best way to go. Thought about making a gasket out of an aluminum can since Ready heli is out of gaskets.

I've had success with all three, use what you want, makes no difference whatsoever as long as you have a good seal.

Be careful with the RTV, if some breaks off inside your motor it will kill your glo plug's filament.

My current rule of thumb is "if the muffler comes with a gasket, use it, otherwise, go metal to metal".

A note on metal to metal, your best seal will be achieved by tightening your muffler bolts right after a flight, the metal is softer while hot and will mesh better.

Ditch the gasket and bolt it up clean.

You can use a gasket if you want to, but it is not required. If I ha a feber gasket, I will use it, but if not, I will true the header mounting surface with an Arkansas stone before attaching it. Either of these will result in a perfect seal.

Ditch the gasket as they make the system come loose when they compress.

I always smear loctite over the faces , they never leak

Yes they works well , if read read the bottle on most lostite it says it locks and seals also , which it does well on our engines , sealant is 2 thick and just gets pushed out .

What, 700?
Sounds like you had a change of heart from the Logo plans...am really enjoying the 550. Neu 1907, ICE 100 6S5000 going well. Best wishes on the 700 project!
