Stripped my FireTeam Pinion

[Goofy]

Appears the grub sheared off and my clip is now POW-MIA. I'm not sure what I should do; order a tekno or RR pinion or use the 15t that came with it.

I have 2 fans cooling the motor which I believe should be sufficient for the higher tooth count? Alternatively, is there concern with using something like a Tekno or RR because they don't have the D shape?

If you’re running 6s keep close watch of temps if you run the speed pinion. Tekno pinions are awesome, with a bigger grub screw. Highly recommended.

I have been very happy switching to Tekno pinions. The 5mm grub screw has made a huge difference in how often a pinion gear comes loose.

Like others have stated really like the Tekno pinions and gears. I have them in my 6s rigs.

Also another good option is Saga gears. I use them on my Xmaxx.

The ones listed are mod1 with the 5mm grub screw.

I had my pinion come off on my Kraton EXB, and one user told me to get flatter set/grub screw to have more contact below. These have worked and been good for me not to back out. A lot of heat the motor makes on the pinion the threadlocker is going to come free....with these I have more contact and more threadlocker.

really wish those 5mm grubs were the standard!

Tekno pinions for sure it looks like you gear mesh was to loose though because just the tops of the teeth are gone, try an 18t tekno pinion and a little tighter gear mesh.

Tekno pinion:

The 18t is a perfect upgrade for a little more speed and the system doesn’t get too hot either.

I've heard orange loctite is the go-to for the pinion grub?

They really should be. Combined with some orange loctite they haven’t come off for me yet.

I just recently started using the orange and I'm loving it!

That’s perfect. Don’t need anything else. All I ever use is blue!

Nice, glad they are workin’ for you. I’m still having good luck with them myself. Especially when paired with 243 blue loctite. Just make sure to clean both threads with brake cleaner or alcohol.

You’re good with that bud. It’s more oil resistant than 242. Worked well for me for years. Just clean both threads good with break cleaner and alcohol. Let it cure at least 24 hours, preferably in a dry environment.
