RE: TT .39 heli engine ruens glow plugs
It still looks like you have injested something or something is coming apart. Look at the head with tiny nicks in the chamber area and then look at the case where the rod looks to be rubbing or the bits of metal are causing it to rub.
also when your going to post pics of the inside of your engine can you clean out all the oil. This will allow us to see the engine better. thanks
Take a picture of the top of the piston. it does look like you have been running it hard. some where on the piston skirt just below the pin and some blowby past the ring.
I just saw that your in roseville lol close to me. I should be going to RC country next week maybe i could meet you there and look it over for you.
