The manual actually recommends a 34T pinion (for stock motors) but I don't see how it will fit...I can't get the motor far enough forward to fit even a 32 without hitting the t-bar and it is maddening! I have been involved in RC since 1987 and have done it all: boats, planes, offroad and onroad, nitro and electric from 1/36 to 1/8 buggy...but this 12L4 is my first 1/12 scale and it is like reading a newspaper in a high wind!! Should I even run the 100T spur at all or chuck it from the start? 19T brushed, asphalt, 160' x 90' layout with one of the 160' sides being all straightaway, Jaco premount tires.

thanks

I love it!! Like reading a newspaper in a high wind.

1/12th scale can feel like that sometimes. Start thinking in terms of roll out when deciding your gearing. Not all 19T brushed motors are alike but you should start off someplace between 46 and 50 mm on the roll out. And you may have to drop down to at least a 96 spur. Maybe more.

The new Associated car (12R5...I wouldn't even consider one of the earlier cars unless it was damn cheap and budget was my 100% concern) appears to be a very good value and reasonably high quality. The BMI is INCREDIBLE quality, genuinely innovative product(s) (the guy who designs and manufactures them is a real 1/12 guy), unmatched customer support (Jason is online pretty much everyday and only a phone call or e-mail away to answer questions, etc). PLUS you support a 100% Made in America company when you buy BMI, not just another "we'll produce 'em in China so we can sell 'em cheaper" product.

Plus the BMI is every bit as good as you've heard. I've only heard mixed reviews on build quality and handling of the new Associated car and haven't had a chance to drive one myself. I have purchased and run two DB12R's and haven't been disappointed since making the change. Tweak-free and feels like it drives itself.

fwiw,

Scottrik

$80???!!! They sell all day every day direct from Niftech for $25.

And yes--they work VERY well once you get the hang of 'em. Every car I build and set with them runs dead straight from the outset without touching trim. Then again, I'm amazing.

I'd recommend you goto your local track for a race day and see what the fast guys are running and what parts are in stock. you might also find a good used car deal. Speed Merchant or CRC cars did very well at IIC vegas 08 winning 1/12 stock and mod classes.

...of course MY caliper measures in the non-real number set... The conversion is kind of a pain in the a$$ but no one will steal it. Hell, no one wants to BORROW it.

I set my width, ride height, etc in multiples of pi so it all works out. I get strange looks from people when I tell 'em my car is 54.7 wide or 1.43 ride height, but chances are they were looking strangely at me already when I was humming the theme to Numb3rs while I was truing my tires to 14.3 so screw 'em.

When I first bought my Big Calipers I thought I would just use them for measuring rear track, but they have turned out to be so handy for a variety of things everyone borrows them and I'm always having to track them down.

I think I'll follow your lead and convert them to measure in pie. The only question now is Cherry or Apple

Oops... I bought other stuff from Niftech and it came to $80. Dee Dee Dee.

Nah...convert to pie and everybody'll want a slice. Then you're left with a couple measley radians (crumbs) and a mess in the kitchen to boot.

Go with the non-reals. Anytime the conversion involves negating negative roots and the quadratic formula people's eyes glaze over and they mumble something about needing to rotate their tires before the next heat. At that point you're so far inside thier heads that you own 'em on the track. If you offer to derive the quadratic formula (or even identify the descriminant) they will run from the building shrieking in terror.

Algebra seems to have had a traumatic effect on some racer's childhoods.

Yeah it does. I love math, but it is so challenging. Once you get it though... it is fun.
