Default 48p or 64p

So i just bought a used ff03 off another rctech member and its my first time running on road. all ive ever needed to use in off road is 48 pitch gears. what are the positives and negatives to using either 48p or 64p gears in this car. If it helps ill be running 21.5 brushless and an fdr was recommended by cuda in the 3.5 range. i was able to find a 70t spur and pinions in the 40s that are 48p but im not sure if they are too large to fit under the gear cover or even able to mesh. my only concern about the 64p gears is that maybe theyre not durable enough, im not sure since ive never ran them before. any advice would be greatly appreciated. im hoping to have the car this week and would love to have a spur/pinion ready to go for it. thanks again.

It's a personal preference as much as it is a strength option.

The correct gearing for 21.5 on most tracks requires the gear cover to be left off. With saying that you need to ask yourself "Do the tracks I run at have a clean enough surface to run 64 pitch?"

I would imagine that the overall diameter of the spur and pinion on whatever 48p gears I use to reach my desired fdr would be much greater than whatever 64p gears i use to achieve the same fdr. That leaves me wondering if I would even be able to achieve a proper gear mesh using the 48p gears. What do u think?

You can get 48dp pinions up to 54t, and spur gears in to the 60's, so can't see gearing being an issue, especially if you are using a timing ESC.

The diameters will be the same, no?
Just gonna have more teeth covering that diameter when you go to 64 pitch.

Kinda like fine thread and coarse thread on screws.
Right?

FF 03 motor esc combo's
I am trying to figure out which Esc / motor combo to use in the FF03
I first had the Speed passion Cirtix system, then everyone went to
silver can brushed. I now run this combo.
Many others are running 21.5 brushless/ Tekin rs combo (non-boosted).
MY LHS says Tamiya is testing a 18 motor/esc combo for the TCS races.
I really would like to get this car setup for racing with a legal motor/esc combo so I don't have to keep buy new equipment.
I race in So Cal.

I am using a Traxxas Stinger brushed motor in mine till the Tamiya system is available. Geared around 4.4 it seems to be able to keep up on straightaway speed. For less than $20, this seemed a more viable option than buying a brushless system, then replacing it with the Tamiya System especially for those who were using a Silvercan.

Grandpa,
That car was a missle with that motor, I think it was faster than most of the 17.5 motors with no timing. Good gage to set up for brushless once you switch over!

So what's the current medium-term FF03 drivetrain spec thinking for non-TCS races? Right when it looked like 21.5/zero was the ticket and many of us started running it 2011 TCS rules came out with the Tamiya 18T combo listed, which is probably closer to 17.5/zero.

So, will you just run whatever until the 18T combos are around and then run those, TCS or otherwise? Run 17.5/zero or 21.5/zero outside of TCS and swap in the 18T just for TCS races?

FF03s have been going great in Camarillo with 21.5/zero. Racing speeds are fun, reliability is high, and tire wear is good.

Hopefully we can settle on something and promote consistency throughout the region to grow the class.

Exactly what our conversation was about

I applaud you Pete and the RoadRunners for stepping up to start the ball rolling!

Others should follow (and be contacted) I know Charlie and his group would be more than happy with the 17.5's as 17.5 around the country has been the "stock" motor class for years.

I'm gonna agree with you guys.

Athough the 21.5 is in lots of these cars right now it seems as though that motor choice came about as an equal to the Silver cans, sort of.

Ever since learning that we can gear the snot out of brushless motors and get away with it, the 17.5 has been the stock motor to equal the old stock motors that were brushed 27 turn.

If Tamiya's choice for this car is gonna be their 18 turn, and the 17.5 is gonna be the closest thing to that (supposed to be less KV), then it makes sense to get these things set up to run those 2 motors together/against each other.

Great, another 17.5 class to add to the decision of which one to run.
