1. Is the bearing adapter supposed to be able to move back and forth a bit on the shaft?? The one near the spur gear I mean.

2. I'm installing bearings, not bushings, but either way the manual doesn't specify different sizes to be used but I believe I need to use a big one on the inside and a small one on the outside (in the bearing adapter that they recommend you cut a little notch to ease the installation of an E clip). Am I right?

I've assembled the whole thing and mounted it to the motor plate. There's really no variables, questionable steps or parts missing, so I'm not sure how it could be wrong.

There is still a little bit of wiggle in the spur gear now. Is that normal?

The wiggle is supposed to be there, no worries!

Thanks man.

I took a closer look at everything and there's really no room for error so I figured it had to be right. I also determined that the play is strictly the movement of the balls in the spur.

Coming together nicely now.

I need electronics badly.....

Looking good! Hope to see it on the road soon

Coming together...

Original and ReRe rear bulkhead. There's more differences than just the bottom of the battery cup missing...






Would this pinion be suitable for either a Reedy Sonic 540 Mach 2 17.5T or LRP X20 Stock Spec 17.5T? It has 16 teeth...

More.....

Whoops. Thanks for pointing that out. I moved them into an "Album" on Photobucket and I bet it's set up as private or something.

*Edit -- appears to be fixed now. Thanks again.

Lookin good!

Nice!
Will we be seeing you in Classic class at Vonats?

Thanks but unfortunately no. This is just for nostalgia for myself and fun for my little guys.

Any comments or information regarding the pinion gear I showed would be great. Would it be suitable for the motor I want? Even if 16 teeth is suitable, should I buy a modern one for the same reason I was advised to replace all the gears in my tranny (modern machining/tighter tolerances)?

I'd like this car to be reliable, fun and fast.... the latter not to inhibit the former and first.

Also any advice AGAINST a Hobbyking X-Car 120a ESC to control a Reedy Sonic 540 Mach 2 17.5T?

Is that pinion 48p?
If it is, it should make an okay starting point. My Rc10 6 gear is geared 23/76 or somethibg like that on 17.5, but I run 2.2" wheels. You can use that pinion, but you might end up wanting something in the mid 20s.

Yes I believe the spur is 48P. It's the OE stock replacement.

So with my 16 it will have more torque but less top-end than with a higher # pinion.....just like a bicycle?

Edit ---I think I'm mixing up terms. You're talking pitch right? Yes again though, the pinion should be 48p because we did run it back in the day with that motor it's attached to before I let the smoke out.

I'm strongly considering this ESC now for both this car and a Worlds ReRe I'm about to buy. Some of the reviews indicate it's the exact same unit as a HobbyWING Xerun 120a V2.1, which I was about to buy, but this unit is cheaper and will come from the US not Hong Kong.

In the bullet point write-up below however, it says it's compatible with Novak, LRP and Orion motors. Why would they specify that? Would it not work with a Reedy Sonic 540 Mach 2?
