Sometimes you just have to say it straight up. Now the OP knows the heat trick to free up a set screw. I use an electrical soldering iron. Once you have rounded off the set screw.. there is not much you can do about it. Cutting a slot would be very hard to do and not much metal to work with. I used that slotting trick just last week on a servo screw... if it won't budge... use some heat to free it up. The new pinion is not that much, but if you yank and pull on the rotor, you may end up replacing the motor too!

The stock pinion is toast... drill it and forget it... you can always buy another pinion.. oh wait a minute.. you don't want to spend anything... never mind ignore.

RE: Stuck pinion set screw
To be honest, heating it up will be my first try. If that doesn't work, then the vice and pin job, and then if not that, drilling it out, and if all else fails, try pulling off. I guess that method goes hand in hand with the vise method.

RE: Stuck pinion set screw
So last night I was working on getting this pinion off. First I tried heat. That didn't help at all, as I think after trying to many times, I may have stripped theset screw. So I tried putting it in the vice. The jaws on the vice were too big to sit the bottom of the pinion on the top. I was like "Crap!" I ketpt trying several things but to no avail, I couldnt get it off. So I cringed and decided to pit the pinion in the vice and clamp down. To prevent damage, i put a wash cloth so it wasn't direct metal to metal on the pinion. I got a hammer and punch and punched it right out with ease with no damage to the 14t pinion. Thank god.

RE: Stuck pinion set screw
I'm glad you got it off but seriously, I understand you're on a budget and I applaud you for sticking with it and not bringing it to a shop for repair, but if it was such an issue to save a $4 part I can't imagine what you'll do if you need to replace a receiver someday.

RE: Stuck pinion set screw
There's a difference between not being able to afford a $4 part and being "cheap" (I use the term loosely). For some, trying to find free methods over spending money is part of the challenge.

RE: Stuck pinion set screw
I dont think the OP should be criticised for being cheap, it may be a cheap part but he may live some where where it quickly becomes dearer due to travel or whatever, i would have to travel 20 minutes one way just to get a prepaid visa to order off the net, suddenly that part is a lot dearer. Sometimes it works out beter to be tight specialy if you have another part sitting there and can get it running again with a bit of lateral thinking. As for tools tho, I always look at them as an investment so am a lot less tight there. At the end of the day he got a result that was good and that was all that matters really.

RE: Stuck pinion set screw
Personally, I chuckled when I read your post. I have gone to extreme measures to try and salvage cheap parts but never bat an eyelash when buying 3 identical kits, engines, and electronics to go racing (always want a primary, backup, and parts car for every class I race - yes, I know I have a problem).

RE: Stuck pinion set screw
Well in this situation, it wasn't really the fact of trying to be cheap. If there are ways to do something without making yet another purchase in the hobby, I'd rather do it "for free" Something as simple as pinion, I know it doesn't require a special tool. I did want to save the pinion for future use, but I probable will not, unless I take a grinder to it so I can use a flat head to pull out the set screw.. But thank you all for your input.
