What is the smallest spur that can be used on the V2?

Not sure what the smallest is but I regularly use a 65t spur (48 pitch) which is pretty small. Great for getting those low FDR's such as 2.4:1 (with a 27t pinion) and larger pinions would definitely fit if you want to go lower.

I recently purchased a f104. I have a 69t spur on it and am planning on running 21.5 blinky. Should i aim for 2.4:1. Or go a little higher say 3.1:1 or so. Thanks pat

Hi Pat

I would start at 2.9:1

To quote from my A-Z of Gearing with F1's article (linked above) - where you go from there depends on:

"- the motor (see table above)
- the track (open with long straight = lower, or short and tight = higher)
- whether you have advanced the end bell motor timing (see below)
- the air temperature (see Motor Temperature below)"

Check out the article for all the info.

Cheers

Is there a plastic/carbon version of the rear diffuser available yet?

Default problem

hello I have a problem with my 104 v2. in tight corners at low speed, she moves well, but when the pace quickens, it tends to expand the trajectory curve. any idea what could cause that?

It is understeering. There are many things that could cause it.
Try to find a set up in this thread and reset your car.

Tires, camber, front springs, center shock oil weight/spring, side pod springs, and riding height front and rear.

I've been trying to setup my Ver.II with the wide and foam tires setup on an outdoor asphalt track and the car is uncontrollable.
Another guy with also the Ver.II has the same problem.
I've been trying several things but nothing helps to have anough traction on the rear tires.
The car even spins arround on the straight line when i go from half throttle ingreasing to maximum throttle.
I will transform my X1 to a wide setup as all the guys in front of me had a T-Bar F104 model and they were able to control the car.
I guess the Ver.II isn't the best choice for outdoor tracks with foam tires.

edhchoe, ok, I'll try. I mounted the front spring drives, hard side springs and also as pre-stressed damper tanguage, nothing happens.
addicted2blue, I roll on carpet indoors. I tried foam and rubber tires, the problem is still there.
thank you for responding.

My setup on our bumpy low-grip asphalt track is getting closer. I still need to be very smooth on the throttle, but it has stopped spinning out when coming out of low speed corners.

What I have found is that the stiffer I make the rear end, the more it is locking it down. When I had it set very soft the car wanted to stay rolled over and not square up after the corner. This lead to the car almost diffing out on the inside tire and just looping around.

On an indoor track i have no problem with rear traction, only when the surface is very cold.
Infact when the grip is ok then it's the best car on the track but outdoors it's a very bad car to drive with foam tires.
Perhaps with another drastic setup change it could work, but so far it doesn't work for me.

That's what i've been thinking about the setup for the ver.II, the car is to soft in the rear for foam tires on an outdoor track with low traction.
With rubber tires it went rather good, but we are using the tamiya 18T brushless motor and that's a very powerful motor.
To much torque for low grip outdoor tracks, and that in combination with a rear that's to soft makes the car uncontrollable.
