Thx-John
start with my base setup for stock, I usually start this setup for club days,
been very good with both ride and muchmore tyres,
Only changes I made for a very very large track were HPI Silvers and different front suspension blocks.

it turns out, 81t spur is too small for my 45t pinion can not touch it. But even I mount a 96t spur, 45t still can not touch the spur cause the upper deck block the motor to stay on motor mount...... I am crazy ...... anyone has working combination(without modification of upper deck and motor mount) which has a fdr from 3.3-4 for original bd7. Even 48p spur/pinion are good for me...

I've gotten an 88 CRC spur and a 52 pinion on the car but I've had to file a small amount off the motor mount brace that mounts to the top deck.

I extended the motor mounting slots closer to the spur. Running A FDR 4.19
90 spur 43 pinion.
I removed some of the upper deck where it touches the motor.

And do not use tekin motor. There is no chamfer on the side, so the upper deck would block the motor.

88 - 92t 64p gears for 3:1 ish ratios

Yes, as per Yokomo instructions, motors with chamfers are preferable

92 tooth spur seams to be the best compromise for FDR around 3.6 to 4. I run a 96/51 for 17.5 blink. But I'm not afraid to grind a little aluminum to make my car work.

Default New 2015 interest

Looks like I need to go with the new 2015 version, only a few in the area are running this but successful in Mod.

Any interest in my 2013 and parts, they are for sale, local Indy/Ohio/Illinois area, tracks I participate.

I'll continue to watch thread for 2015 suggestions while mine is for sale, and then upgrade.

Roller chassis and parts per photo, $100.00 SOLD,

didn't take long to sell, now for the new one

Why do you NEED a new one? What is wrong with the one you sold me?
