Default Serpent gearing

What would be a good starting pinion with a 84 spur gear. 13.5 motor, thanks

Anyone running a d4 1s 13.5 on their wheeler? Looking for a ball park endbell timing setting just to get started. Thanks

I run 13.5 4WD buggy as my primary class. I also run 17.5 2WD almost as often. (mostly office carpet with mini-pins)

Ran my xb4 for the first time last night at rainmans indoor clay track with a d4 13.5. Only had 5 minutes of practice with brand new tires before the first heat but ended up with tq and the win. It was a small class but this buggy is on rails! As for timing and gearing ended up cranking the endbell timing up to 55 and with a 27 pinion motor never got above 104 degrees. Putting a 28 on for next time.

Pardon my ignorance. We do not have a 13.5 wheeler class. But are you guy's running blinky or boosted?

I run a Kcar ZX5SP with a 13.5 Killshot HT rotor/stator that I converted to use shorties instead of the saddle packs. Just the mod shaved off nearly 80 grams of battery wt. I have it geared at 76/26 with 35 of can timing running blinky mode with a HW esc. Before the mod I was beating some of our fastest drivers running 6.5s in their more modern cars. The secret was that I could run cleaner laps with the 13.5 then they could with a mod setup. 13.5 4wheeler cars are no laughing matter.

I ran 13.5 blinky setup in a dex410v5 yesterday in a mod class for the indoor carpet track i attend. I have to say this was quite fun reasonable power for the track. Once I stepped it up in gearing for the main if I didn't pop a shock shaft I think I could have taken the win.

The Maclan motor I used worked excellent at 50 degree timing.

I had a mishap with the ESC (hobbywing V3.1) fan and had to remove it, but no issues with esc heat at all and I have no vent holes in the body.

To me at least, I think this class can be a great way for people to get involved in 1/10 4wd e buggy as a good entry point.

I just run blinky. It is surprisingly quick even with just a 13.5 and the speed is comparable to my 17.5 2wd buggy so its not a huge adjustment running back to back classes.

out here the last race I managed to win, though, credit where credit is do, lead driver did break lol.

Running a 13.5 blinky versus a field of what appeared to be a lot of 10.5 motors and almost a Hot Bodies D413 spec class lol, I found only place I really needed a bit more with punch. I am thinking of going with the ultra torque rotor that Maclan sells for my motor.

Are you guys running the class finding you are going to the higher torque option rotors (if available) over your standard "12.5" rotors that come with the motors?

Every place I have encountered that offers a separate 13.5 4wd class explicitly requires blinky. A 13.5 with boost can be almost as fast as a full-mod.

Something may be wrong. a 13.5 4wd buggy should be WAY faster than a 17.5 2wd car, in every way. Are you geared appropriately?

I would not use a 84t spur for 13.5 in a SRX4. Try 78t spur with 28t pinion
