Trackmaster transmission

[Frankentruck]

I have an RC10 Trackmaster transmission that needs a little work but has a lot of potential. However the big hurdle is it needs outdrive cups. Anyone found outdrive options that will work with it? Preferably something affordable. I am kinda cheap.

If they are 5mm you could use kyosho optima/ultima outdrives (not rere) or ours from the trx1 bone kit

They are 0.250" / 6.35 mm shafts. I could open up 5mm to work. Do you know if either is compatible with an RC10 dogbone end?

Ours are hardened and would be a serious pita to drill out. Ill check bone fitment shortly but from memory the bones fit fine, maybe a tad loose but definitely usable

CSC Slider Shafts, or the cups from a Bolink Invader with the independent rear arms would be options.

I'm going to try the hardened PITA direction first.

I haven't tried fitting outdrives yet, but I took care of replacing the banged up side plates with some freshly cut Factory Works parts. Thanks again Jeff!

I need those side plates for the Diamond One build!

Got them ordered!...if they don't work it's @Frankentruck's ass!

I don't swing that way.

The bearing holes needed to be opened up a few thousandths. Same with the screw holes for the spacers. But that's better than starting with oversized holes.

Lol...yup, that's fine, don't mind opening them up a bit... better too tight than too loose!

[Frankentruck]

The G10 plates you ordered look nice! I considered that option too.

Thanks, I did have to move that hole where arrow is at bottom, and shave of that part at top cause it was hitting the bulkhead, but the bearings dropped right in perfectly!....with a few tweaks, he can put it on the market!

I'm sure it's a little different shape for Ultima vs RC10 but overall probably very similar.

After the feedback I adjusted the holes to the sizes I typically use. I don't like to modify customer files when supplied but once I sell to others I definitely try to add my $.02 haha
