I think that should work

Eeek! My kit came with that one, but I bought the plastic 51T from Mike.

Another problem now is; where can I get a steel 30T M1 pinion? Sdp-si only has them in 303 SS which is really soft, isn't it? I'd be comfortable if it said it was 304, that stuff is mean (it killed my rotary tool).

They have 32-36 tooth mod 1 in carbon steel with 8mm bore and 6mm face.

wow what a car. It took me a while to read this whole thread, looks good though.

So after reading this thread I am gonna buy the Ultra GTP rolling chassis and convert to brushless.I have a Neu 1512/1.5D and a MMM when its fixed.Can I use the center spool with Mikes rcmonster motor mount.What about bodies?Can I use the rcmonster battery tray?:whistle:

I saw those. It would have to be 5mm bore to fit the motor shaft. :(

Thank you, sir. :mdr:

Yes, and yes. Nice to see I inspired someone to empty their wallet! :wink:

About the bodies, Tower has two: Viper and Porshe.

They have 5mm bore mod 1

So I got the gears- those acetal w/brass hub and set screw ones. A 30T (pinion) and a 40T (spur). They fit great, and it's REALLY fast- as far as I can tell on my street. Only problem is I can barely start from a standstill. It cogs horribly with the tall gearing. You (B4maz) said you weren't seeing any cogging with your setup, which is also what I would expect with your gearing choices :P.

Do you think it could be the controller? The Sentilon may not perform well under high starting loads, agan being an air controller it wouldn't have to. Would more capacitors on the ESC help this at all or is it most likely a firmware issue? Should I discontinue running it until I get a MMM??? :mdr: I know they start very smooth and the slow speed control is excellent.

What a cool project, :yes: you should race Lic when he gets his 4 Tec running..:whistle:

I wish I knew more about the Sentilon controller. I didn't think cogging would be that bad that you couldn't even get the car moving. It sounds like a controller issue because I know people that run the same motor/batteries but use a Castle controller and don't get cogging that bad. I'm sure the MMM will be much better. I don't think capacitors will help much with cogging. I would definitely upgrade the firmware to the newest version. They might have fixed the problem with firmware.

B4maz: I don't think the Sentilons have upgradable firmware..... I want to buy a new ESC anyways because I hate the mechanical brakes. I put the second disc back on and they still fade to nothing after a few stops. There's just too much heat present. I'm thinking HV110 over the MMM, should I ever want to go FASTER.

TDC57: When, and IF. :lol: So long as the course has no turns, I think it's in the bag.

Have you tried to use high timing on the speed controller? That might help with the cogging.

No, I will try that. It was so excessive that I doubt it would be readily driveable after just a timing change. :cry:

Well I still don't have a controller, but I have braces! :lol:

Just made them last night. It's some 1/4" aluminum tube with the ends flattened/drilled/sanded. Those are my (hopefully) uber traction tires. They are Proline 1/8 buggy MOABs.
