Stripped Glow Plug Empty Stripped Glow Plug

I have a high compression glow plug that has run beautiful for a number of months. I actually trade it between my best running motors as always runs so well. Today it started to slightly strip the threads (as I have removed it like 50 times).

I was wondering a couple things. It hasn't completely stripped but is starting to think about it. If I was to pick one motor I like and thread it in with thread locker would this be acceptable. When it finally burns out I can still get it back off with effort.


How hot do the .051/.049 cylinders get? The thread locker I have is good till 300 degrees.

Just was wondering how to get the rest of life out of this glow plug that has been so faithful and now threads are not holding well enough.

Thanks

It is strange that the threads begin to strip after only 50 times of head removal. I always add after run oil by removing the head and have not observed thread stripping even with the oldest heads.

I believe a hot COX cylinder can reach 120-140 celsius if running on bench with high nitro on a hot day.

Hi Balogh
I do tend to tighten pretty good the head. Maybe I am needing to add the oil I never have done that before. But after a run plenty of Castor and Klotz oil is there so thought would be ok?

Thanks for the temperature 140 c that should be about 284 F.

Hope you're getting some more flights at Balaton?

Take Care my friend.

Thanks, Darren,

I add the after run oil to moisten the cylinder, not the threads Smile just wanted to say that I am also often removing the head while others may add the after run oil through the exhaust ports and remove the head only if the glow filament has been blown...

Luckily the owner of the small friendly airport near my summerhouse at lake Balaton is a modeler himself playing with RC gliders, and has all the empathy for glow engine aero-modelers grounded by the crazy drone law of Hungary...so I fly an outlaw in a very friendly field, inherently dedicated, situated and geared to flying... Smile
