Wow, that's like a 6.5:1 final ratio.... Are you sure you didn't mean 18t pinion? 28 seems a little large. Most stock brushed motors (I know you are using BL in this case) like a 9.5:1 final ratio for 2wd buggy. (please understand I could be entirely wrong here) In my case when switching to BL from Br, I only made a 1-2 teeth larger change on the pinion.

Actually that's a pretty good/safe starting point for a 17.5. Some guys go even higher. We've been running 5.6 to 6.4 FDR, even with some timing from the speed control. Some guys are using no slipper adapters so they can run smaller spur gears. Definitely start with the smallest spur that fits/is available. I know its hard not to think you are going to lose punch, but it never seems to happen. It still attacks the big Supercross style jumps.

Of course whether or not you want to run a vintage car like this is perhaps another matter, but the 17.5 motors can handle it. Unless perhaps if its significantly overweight, or an older higher drag tranny (6 gear? bushings, etc). The gearing mentioned is on a modern buggy right at the weight limit, using lipo.

But we also run brushed 27T stock higher, up around 8.0 FDR, so your mileage may vary as they say. Of course with brushed you can't run real long this way, but no issue so far with the brushless.

alright guys, here is my RC10 Team Car with a 17.5 Novak brushless motor and lipo battery. I'm (expert driver) racing the guys in the amateur 4wd class. My fast lap was a 16.6 in that race and my time was 27 laps in 8:01.

I thought I was excited about this race before. Now I am.... well in the words of Stimpy: "I'm so excited I can barely contain myself!" Thanks for posting that video, it's great to get a picture of what the track is like, it looks like a good one. I can't wait!

Man, I'm gonna have to get there soon to get a couple of laps in, I haven't raced anything in so long, it's definitely going to be fun...

Nice vid Mark, the car looked overly dialed.......... traction roll!

Yeah, I had just raised my ride height before the race and I raised it a bit too much The diff needs to be rebuilt pretty bad too, it will get a little more tweaking here and there but overall its pretty close to where it needs to be. I'll work on posting a setup sheet for it when I'm satisfied with it. Then I get to work on the vintage 4wd

thanks for sharing your setup info, it is MUCH appreciated.

thanks also for the vid, there is absolutely no way i will be able to keep up.

very nice mark! now I am pumped too. cant wait to see your set up sheet. is this the same layout that the nationals will be held on?

Just FYI guys, I will be posting some pics here and also sharing some with Jimmy at Oople.

thanks for the video. now i know where i'm gonna stuff hoopty every time i come up to lap him.

Are the mains and qualifiers 5 or 8 minutes?

I asked before and they said 5 minutes

Cool, thanks.
