os-91 exhaust sealing??

[heliward0]

i have fitted my new engine to my rex-700 BUT i havent got any exhaust gaskets for a 90 size,, so i rang my local shop and he told me to use EPOXY?? I HAVENT HEARD OF THIS BEFORE??? so is it best to order some new ones or do you guys use anything else??

gut feeling is just get the right products and do it right,,

Hi Nathan,

I have heard of a skim of epoxy before, or as I do a thin skim of silicone.
To me a gasket seems more 'engineered' or what about a drop of liquid gasket.

After all, all it has to do is resist heat, stop gases escaping and not blow-back into the engine.

Anyway - I thought you were solid leccy!! lol

i have and do use silicon and cornflake packet gaskets on rc cars!! but on a 90 heli i am a touch more cautious..

Never had a problem with silicone on my 30, but on a 90 what would be different? Just a confidence thing.

One thing I do know about our wonderful hobby is that if it don't feel right it ain't right.

Go for the gasket.

Hi Nathan,
You can use Silicone, or Epoxy, or nothing at all (as I do).

I just fit it without gasket/silicone/epoxy and do the bolts up tight - works for me

theyre a lot neater than epoxy... I have removed and re used 2-3 times on one, and no leaks, so 5 will last you a while....
