House's Generic Ti-Fighter

Mine fit into the large 3rd with no issue, pin must centered. It was the corner radius on mine. Not sure if the is House's problem. Love seeing these fighter builds coming out. When are you going to take over making little 3rd gear?
 
Well if my pin hole was off center then my pin is bent to fit now...
The small gear and large gear are shoulder to shoulder and only have
about .001" of runout. I do notice that there is a little material sticking
out below the bearing still, though. I will turn that down tomorrow and
see what happens. I may go look for a stock one to measure and stick
in there for a trial fit also, but not sure if I have any left, I gave a few away.
 
Measuring a stock one will not help much...
you would have to measure about 12 and take an average....:shock::shock:

went through that when doing my delrin cases......

and yes, nothing should stick passed the bearing...
 
I was just hoping to figure out if it is a length issue or a bearing seat issue.
ie: Do I need to machine more off of the length or put shims under the bearing until no shaft sticks out.
I was able to press the bearing on even further, now this much 3rd gear sticks out. :shock:
Since you found that much variation in your testing, I will just machine it off and call it a day... :)

On another note, it doesn't seem that mine has any parallelism issues that SkaldidDog found in his wife's new rig.
Mine is pretty square. And TIGHT!

On both sets of my AlFighters, there was a problem with the 3rd gear. My fix was to trim down the ledge that is between the small 3rd gear teeth and the bearing journal. I noticed that the teeth side of the gear shaft didn't stick out past the end of the bearing, like the idle side did. So I ground down the end of the idle side, and then trimmed the ledge on the gear side, so the gear teeth were right tight against the bearing inner race.
I noticed this tightened up the gear mesh and as soon as I did that, my cases snugged up tight and there was no binding.

All 4 of mt AlFighter cases had to have the exact same thing done. Two with SDS 3rds and two with RC4WD gears.

The way I trouble shot my axles, put one gear in at a time and see where the binding occurred, starting with the locker and working towards the motor. Soon as I put the 3rd gear in, wham, locked right up.

If you have any questions or need any help, please let me know.
I probly spent 80 hours working out the little quirks on my sets.

Another piece of advice, all of the gear teeth have horrible finish and the mesh typically sucks. Use some 600 grit sand paper or a small key file and clean up the faces of the teeth. The loudest part of my fighters are the brushes clicking on the armature segments and the servo humming.
 
Thanks for the tips guys. It seems the 3rd gear trimming has finally freed up my locked up front axle. Yay. I popped out the one in my rear axle and it has the same issue, but was working decent. Put this one in there and now it is smooth as butter. I will trim this one down tomorrow and hopefully move on to the next step of assembly finally...!
 
Build is looking good. I have always been a huge fan of these axles.. And have always wanted to own a set, just never got a chance. I saw these back when I first got into crawling, at the time I didn't know what they were, but they were just bad ass. So like Ty said, it's cool to see all of these "fighter" builds popping up.

Glad you finally got the motivation to finish your rig. It's gonna be sweet once it's done"thumbsup"
 
Yeah Will, where are our Third Gears?! ;-)
I will look more closely at mine. I remember pressing one on. Hmm...:idea:

Well.... When you put my other gears in these axles. :lmao: There has yet to be money made with the other 3 gears we currently sell. May have alot to do with the other vendor that started and also stopped as well. Could also be the cost. I blame the cost, but the investment to drop the price is likely not worth it with the way comp is lately. Unfortunately. I'm just a small vendor and don't have the resources or cash flow of others. I have the drawings, just scared to pull trigger really.
 
Electronics are in and ready to go.. Bending up a new tierod later today...
How many degrees of Caster do these things seem to like?
 
Will that servo mount fit regular Berg V1s? If so where can I get mine at?

House hit the nail on the head. Compare the motor placement on your berg to the TI/AL fighter in House's pic. The motor is on the axle tube.. The Berg V1's have them set back quite a bit.
This set up isn't bad but it can make the steering a little tricky. You have to get the lengths just right to make everything work properly.

My advice, stick with the steering servo in front of the motor.
Lots of vendors on here make the mounts.

House, looking good with the fighters..
If you need anything for these, let me know. I have spares and a CNC at my disposal. Isn't much I can do for these.

Can't wait to see her all finished up..
