I blew the plug and threads out of the head on my engine the other day and I need a replacement NOW!! I was wanting to fly after Christmas and into the weekend but without a head, that will be impossible!!

Does anybody in the Austin Texas area have a spare that they would be willing to sell me? Or a shop that can get me one ASAP? I tried the helical option but I can't find it in the 1/4 - 32 size!!

I need help!!!!!!

Thanks,

Ralph

Engine size? Hit up Heli Proz South, if anyone can get you the parts in time its them.

I give up on Loctite, nothing lasts long enough to vibrate loose anymore.

By my count Two.

If the wings are traveling faster than the fuselage, it's probably a helicopter.

I tried Heli Proz but they are out of stock until NEXT
Wednesday!! No luck there.

The thread size is 1/4 X 32 so a helical set is out of the question!! Looks like I am grounded for the weekend!!

They make helicoils in the thread you need, I have personally used them but with little luck keeping them in for more than a few flights. Many people have had good luck with them, I think I just suck at installing them correctly.

Would really help to know what motor you have, there are a few heads floating around here for most common motors.

No offence Heliguy. I have seen threads about this subject too many times. (stripped threads). I am a maintenance supervisor for over 14 years now, thats a hands on position.

There is no, NO, reason to strip threads, ever. If a; bolt, nut, plug, anything threaded is not going in easy and smooth, STOP, back it out and try again. Could be threads, male or female are full of junk, clean em up. Could be you just started it wrong. either way moving forward and just continuing to assemble is a big mistake. One slight exception, and not because I've done it, I havent, is tightening a muffler, those mufflers are way soft and as you know it needs to be as tight as you can get it. Still a little caution and attention can avoid the problem.

Just a couple of hints. Like I said make sure you start it right. I sometimes put the item on and turn it backwards, like I was removing it, until I feel a very slight, "Tick", thats when the starting threads have just past eachother and when you feel it, start turning it in. On allen sockets, make darn sure you are getting your wrench ALL the way to the bottom of the socket, do just that and your socket strips will go way down. Make sure you have a good wrench AND it's corners are not worn, if they are grind the wrench end down till you get to good clean edges, Keep water close dont over heat the wrench. I love those ball end wrenches,lots of fasteners are almost impossible to get at with out them BUT the edges wear very fast. If one turns in the socket on you, stop using it for that job, go get a straight one or a new one and use that. Lots of fasteners just wont come out with a ball end. Use the straight one whenever possible. On very small set screws (aka grub screws), I do not reuse them, the scocket strips too easy. If you need to cut a bolt down to lenght, put a nut on first, thread it down way past the cut area, then cut and back off the nut, gives you good threads every time. If you know you are stripping threads STOP as soon as you can, run a tap down the cross threads,if you are lucky and stopped soon enough you'll still have good threads to grab on. If its just a gonner, IMO, helicoils are just a bandaid and will fail. I never use them.
Anyway my rant is now over. I have stripped many threads over the years, I learn slow. Been many years since Ive stripped a thread.

Another quick hint comes from my car work days, when installing a glow plug, put a lenght of fuel tube on the end and use that to start the thread, the grasp on the end is pretty slight and it just wont turn in the threads if not started right. It wont turn it in far but it will get it started right.

These are a little pricey but way cheaper than a new engine
MSC has them and can be ordered online

I have been doing what FBoss posted a pic of for over 10 years. It is THE best way there is. You can NOT hurt anything. I screw it up flush and then tighten with the glow plug wrench. Not that hard either as you are not torquing down lugs on your truck it is a aluminum head.

I watched an older gentleman at my model field do that and I have been doing it ever since.

Sorry Heliguy600, dood is right, I inadvertently clicked on 1/4-28. I have not been successful finding the -32 variety. Best of luck.
