Could someone recommend a starting place on a pinion gear for general fun-running with an X20 13.5 stock motor? A new kit will arrive for the weekend for me but I'm not sure where to start with gearing.

We decided for a gearing of 5.0 at our club for blinky. With this you do not risk the motor at all. Temperatures stay low, the car is fast and if you want more speed you can start from there.

Excellent, thanks buddy. Will start there and see how she runs. Not sure if I'm looking forward more to the build and setup or running .

The X20 is happier at closer to 4 than 5. It's a torque motor, not a revver.

I ran mine at 3.9 (large track) with the 37.5 timing insert and it used to come off at a good temp (around 70degC).

I agree, for a torque motor, best to have a lower FDR.

For TITC 2015, blinky hand out motor was a Bandit HW (torque motor) and we ran it with 3.1 FDR, 35 motor timing (open and large track) and the motor temp was okay.

for boosted 13.5T, same motor, FDR was around 4.3 - 4.7

We had a minimum of 2 fans on the motor though.

Just as a point of comparison.

Just keep in mind that X20 is running hotter than many motors. If outside temps are around 25-30 *C and asphalt 40-50 *C it is easy to reach unhealthy temps in the motor.
I am running on a small/medium ashalt track . He asked for a safe setup not one where you need two fans to stay competitive with the worlds best drivers...

When you all are quoting ratios, FDR is the final drive taking into account the full internal drivetrain ratio (layshaft pulley to diff gear as well), not simply the primary pinion to spur ratio, correct? Just want to be sure I'm on the same page here.

yes.. that is correct. there is an app out there for phones.. that has the Xray T4 FDR calculation.. its called rc final gear ratio. it calculates it for you. just type in spur and pinon numbers.. and calculate.

i did not create the app.. i just use it.

Hey guys,

Just got back from Gulf Coast raceway down in Porter where they held nitro sedan worlds at. I ended up using the PSS shock system down there and thought my car developed more traction than all the other xray cars.

Go Xray. Right now it's probably the most advanced in features and adjustability. I foresee most will try to catch up with their future releases (which makes youwonder what will Xray do next). Right now I think the sway bar setup is the nicest on Xrays and for once you can adjust it with minimal fuss. The rest look like afterthoughts.
Personally I have my eyes both on the next Xray and the TRF. If they're both good, I might get both.
