I'm just waiting for my Novak Servo regulator to arrive so I can attach a small lipo receiver pack.
I'll let you guys know how it runs.
Hey OD - you wanna be a guinea pig?

:tire: :tire: talk about a power to weight ratio :tire: :tire:

But the guy we are talking about here is having trouble controlling his car with a 19t, so even if he is running outdoors a slower motor will help him learn.
We have been discussing the idea of silver can or something similar here. We have a couple of small carpet tracks and since they have allowed 13.5 in stock, there is no entry level class anymore :cool:


To add proof to this discussion: - I am the guy having trouble contolling my car, by the way... - the first 1/12th car I drove was a crc link car with a stock motor. It was after the race was over so the battery wasn't fully juiced up, but still had some runtime left. I had a blast driving that little car!!! :D I hit a couple of pipes, but made it around the track fairly well. One of the faster guys stayed out and drove a few laps with me - I couldn't keep up, but I looked much better during that couple of minutes than I have since I got my own car and started running 19t.

Why don't I race in the stock 1/12th class, you ask? There was not enough interest and the class went away...

Thanks again for all of your help!

I will be racing again in a couple weeks at the two day race in Rapid City, SD. Anyone going???

I... - this is hard to type - can not... make it to the.... North Dakota Prarie Knights Casino race :cry: :cry: :cry:

I will let you know how it goes. until then,
Jeremy

You bet! Your last lipo car was scary fast :nod: This one looks promising, and the fact that the packs look like C4 doesn't scare me at all. Let's charge it in your pit area, though :lol:

Personally I was waiting for a lil' more from the Euros but luck was not on their side this time...

Thanks OdP!

You may be right more than you know. I like touring cars; But: This last weekend, we went to Omaha and my 5 year old son - who usually races a stock truck in the Novice class (offroad and carpet) - ran my T2 '007 with rubber tires and won the Sportsman (beginner) class. :nod: So, I don't know if he will let me run that car again. He kinda likes it!!! :D

Signed,
Proud Pappa :D

You got it Jason. It is the same track we had our regionals at that Yang came down to run.

I've been running touring cars for a little while and just started running 1/12 scale. Just wondering what I should be doing differently with my motors. I've been rebuilding them the same way as my tc. It's been working ok but I need more. I run a co27 indoors on carpet. Anybody have any tips? Thanks :D

cool,if you can get a KD.it is a much faster motor.i set it up with that brush/spring combo and when you check it you should be drawing about 10 amps and about 8000-9000 rpm at 2 volts.these are the numbers i shoot for.break it in for about 200 seconds and throw it in. ;)
