Glow plug for LRP 28?

[sharkattack99]

will this be a good glow plug for the LRP 28? http://www.amainhobbies.com/product...l-Medium-Purple-Sport-Glow-Plug-25-30-Nitro-1

any other recommendation would be helpful i was planning on just using the plug the motor comes with. will be using 30% nitro. but want a back up just in case.

I think the MC8 would be a good choice for ya to use..

I use an OS8 in mine works great. I use OS8's in all my engines.

OS #8 plugs are short plugs, they aren't the best choice but will still work ok. They are about 2.5 threads shorter then most standard plugs.

i seem to be blowing plugs, do i need to add a shim to the head? cause thats the gist I'm getting from reading alot of posts that i may need to add shim to my head? it doesn't seem to matter if I'm lean rich just right they don't last more than a tank or 2 if I'm lucky I'm running byrons 30% in an lrp .28 (so you don't have to look back) iv tried all the ones that have been recommended and I'm still blowing plugs. and if i do need one does anybody know were i can get one amain doesn't have them just ofna and others, and tower has them but it comes with the plate that the glow plug attaches to and i don't need that.
