The kit yellow springs which I list as "florescent yellow" when I write notes in my book, work more like a progressive rate spring in my opinion. The initial spring force feels more like 19 lbs of force. They don't seem to be as soft overall as the SNR red springs, ... but i have no way to measure spring force.

After a few mishaps of low batt. power diring a race I hastily moved to a 5 cell hump pack. So this works for both my sons cars (RTR Pro's) and mine (a kit Pro). I hated to cut my top radio plate to fit the battery in, but I never run out of power.
But now I need to trim some weight off the car, so I'll try one of the AAA (1100 mah) packs and see how it holds up.

I hear that engine increases your heart rate

For gearing I would recommend a minimum of the following combos:
pinion 20/26 and spur 55/49 and 56/50.

I am using pinion 20/26 and spur 56/50 for my Picco and OS TZ engines on short to medium tracks.
Spenz what gear combo are you finally using on your missile.

I'll have to look and see. I think I remember the FDR on both, but I need to look at those gears again

21/55 1st, 27/49 2nd, giving you an FDR of 6.55 1st, 4.54 2nd.

In comparison, the FDR on the MTX4 is 7.49 1st, 4.97 2nd. A lot of those drivers drop a tooth or so on the spur gear to get a little more top end though.

The hot setup is to use the yellow Mugen clutch shoe and the Mugen super hard spring. It's a good reliable setup for a snappy and responsive clutch.

In looking over the gearing, I may readjust mine once again. I know my first gear is somewhere in the 7 range, which may be too short for the tranny. I'll try a high 6 and see how it goes from there.

Default Must have optional parts

Marcos_J
There are a couple of optional parts that you should consider adding to any CD3.
1. aluminum A-arm mounts for the rear. The plastic ones will not hold up from accidents and will allow the hinge pin to pop out.

2. a wide bumper guard that is almost as wide as the front track width. I have mine narrowed a bit (180 mm) but it protects the front suspension during a hard collision. This will 'reduce' the occurrence of the steering knuckle poping off of the pivot ball when you have an accident.

3. 4mm rear upper link turnbuckles. Lunsford titanium if you can afford it.

4. Use front wheels that have an offset of 1 to 2 mm. The 0 mm offset wheels tend to rum the tie rod ball ends and weaken them.

Spenz,
I installed the Mugen Yellow clutch shoe. Launching seems easier under low traction conditions. I am using the stock Power clutch spring. How much harder is the Mugen (hard) spring? I am assuming that I will need a lot more traction to use it.

Default Marcos CD3 setup

Hey Marcos_J,
the setup looks like a winner. How is your acceleration with the current gearing? Some of the other CD3 racers are using very low/aggressive gearing with the Red Dot engine.
Actually I miss using the 21/27 , 55/49 combo I like to hear the engine spool up at wide open throttle.
