Sean, if you are able to test on the asphalt this weekend, please post your findings. I am signed up for the ashpalt nats with this car and the first time I get to run it will be at the event. Kinda scary!!!

I have read that there are size and also weight issues with trying to use a regular GTB in a 1/12th. Have you considered the Tekin? Its tiny!

Yes, but you have to make it look like the 4cell version.

The only difference size-wise is the heat sink and fan. Take them off and replace the heat sink with an aluminum plate. The plate on a GTB 4 cell is ~.063"; I've used .032" with no problems. As a bonus you can plug your PT into the fan position on the esc

This pic shows the PT and a cut-down heat sink. The cut-down heat sink is more work and weight that you don't need.

Sorry about the late reply, we've been pretty busy the last week or so.

I ran my car on our local asphalt track and it was pretty good with a mostly kit set up. The only thing I changed was the center shock spring, ran a red instead of gold.

The most important part of most any 1/12th car is getting the tires and tire sauce right. I ran Jaco lilac fronts and pink rears. I never found the best tire sauce for our track so I just ran the tires dry. It wasn't the best the first couple of laps but once the tires "warmed up" it drove pretty good. All of the sauces I tried just made the car real greasy and it wanted to spin out until the rear tires dried up. Without sauce the car was a little low on grip but it was an even loss of front and rear grip. I know once I find the best sauce set up the car will be very good.

We haven't had much experience yet with these motors in 1/12th, I do know that the gears are big. I think 13.5 will roll out around 60 mm and 17.5 might be 70mm or higher.

Based off of what your saying my guess would be that just changing the spring/oil combination to a stiffer setup over compensates for the loss of steering so I'm thinking in those setups they raise the shock to lessen the effect of the spring change just a bit. Does that sound plausible?
I guess the way you stated it makes sense. I normally try to make sure when I change from an angled servo to a flat servo to keep the angles on the tie rods close to the same. I have run my car again and can confirm that raising the shock on the chassis mount will take away some steering.

A few day's ago, I've also driven the Associated RC12R5..
And it's just great!. Last year I've driven the L4 Modified, but this R5 is just wonderfull. Stable, but a lot of agression on the front tires.
I was a bit bumpy track, but the car had no problems with that.
Only thing i noticed, that the side shock upper cap is a bit weak. There is not much Tread in the plastic thing. And that will make it hard to place it straight on the tube...

Hope it will get some good result's this year!

Greetings Robert Krens

Which spring do you mean?

I've used .22's on the front, the kit side spring's and a blue center spring (pretty hard)

The Blue Asso spring is a 10.0 spring
Order Nr: 8452

See the old L4 set-up sheet for the springs with their order numbers.
