[REVO-5309]

Hey guys, looking at buying a picco .26 jl and need to also seal up and repair a couple things on my trx3.3. what sealant does everyone use/recommend?

High temp copper RTV sealant is what i use

 

[Candyman]

Yup. I use Ultra Copper on my engines.

This is some rc specific stuff that is wicking so you put it on when engine is assembled and it is also safe for nitro fuel (unlike most gasket maker).

So lucky 7 can be used fit sealing from inside motor as such as well as outside. And what brand is the copper stuff u guys use or just any?

I use permatex ultra copper like in the link above, but the lucky 7 stuff really interest me so i bought me a bottle and gonna try it out!

Lucky 7 is the nitro engine sealant of tomorrow. I've been using it for 2 years on my engines and I haven't had any air leak issues since. You just have to make sure your engine is nice and clean. I leave the backplate bolts hand tight while applying the sealer, then I immediately tighten them afterwords.
The rtv does work, but nitro can eat into it and it always makes a mess!

Ok so they say u can use this on your needles, does it dry hard or is it a soft, flexible material? Won't using it on needles make them hard to turn?

Talking about lucky 7 btw

 

[MethaneJunkie]

I would NOT use on the needles!!!!! It does dry fairly hard and will make those needles stick i would think, i use team associated "green slime" grease for the HSN and LSN. Just enough to coat the top threaded part of the needles.

+1, green slime for the needles.
