Default Picco .26 glow plug cannon

After finally getting my Savvy X running well, I decided to grab an old Savage SS that came up for sale at a good price. I gave the car a thorough clean, stripped down the Picco .26 big blog and fired it up. All good.

As I was tuning it though, the glow plug died on my (was super old) so I had to replace it, but as I pulled it out of the engine most of the thread came with it :-( Now the head button is stripped, I can get a glow plug onto the last bit of thread in there and seal it with a bit of green slime to get compression, but as soon as you hit the throttle.....BOOM. Glow plug cannon, fires it straight up.

As far as I can tell the button head for this engine is discontinued and I can't find any online retailer that has them left. Any suggestions on how I could possibly repair the thread?

Ooh that's stinks that's a really good engine too....
I would just keep looking for an old stock one, someone will have one somewhere.
If all else fails you could try to get one from a different .26 engine, I'd compare them to make sure all the sizes are the same

Yeah not too keen on replacing the engine for $200+ when the whole thing cost much less than that. The picco is in good condition too, it was filthy when I got it but after stripping it down I realized that it had barely been used. Unfortunately not really sure where to look for a replacement part.

Was considering perhaps welding it shut and tapping a new thread? Could potentially draw it up in solidworks and get a new one milled, but not sure if anyone I know will do the milling for "mates rates".

Dont get a losi 454, rubbish engine with a rubbish carb that cant hold a tune to save its life.
Just an opinion based on my first hand experience.

A picco boost .28 for $229 is lightyears better.

Extremely unlikely to find that engine for anything less that $300 in Australia seeing as it isn't distributed here. Choices are limited and prices are generally a lot higher.

Learned about Helicoils, but of course glow plugs are imperial and a completely abnormal thread size just to make life easier

Bought one of each of these in the hope that I can get one of them to fit-

The latter one seems to be the money shot, 16.75mm is pretty much exact. Nothing else matters too much, if the holes don't line up I'll Laser cut a new set
