I've done a lot of searching, but can't seem to find a good answer to this question.
I am upgrading my RC10T that has a stock Stealth (but now with a b4 slipper setup) to a Tacon 11T 3200kv brushless setup, using a Hobbywing Xerun 60a ESC. Any thoughts on where to begin with gearing? I am running 87T spur with 18T pinion on my mild modified brushed setup currently, but I dont think that kind of ratio (4.83) is recommended for brushless.
Is there a good target ratio I should be moving to with this kind of brushless setup?
I can tell you that on my 10T using the Tacon 2950KV and a 35A Hobbywing ESC with 2s Gens Ace lipo, I'm geared at 81/26. The motor and ESC never get hot after a 8min. main. It has tons of torque and accelerates to nearly 40mph on the straights in a 1/8 scale track. I generally lower the timing from 0 to 15 degrees max.
So my brushless set-up finally showed up and now I'm even more confused about applying it to the car...I went to the local track to pick up a longer sensor cable and asked around to see what guys were running for an FDR and the consensus seemed to...

It is a 17.5t, and I do have the boost coming in pretty low...4000rpm I think.
I received a couple pinions in a deal I made with a guy and I've had some issues getting them to stay on, but a dab of clear nail polish on the set screw usually fixes...
HELLO This is Don. THE Rustbucket.
I have a question that someone may be able to help with. I am changing my RC 10 gold pan with the stelth over to brushless. I have a 87 tooth spure, Also setting it up with a 17 .5 novak any add vice on pinions....

HELLO this is Don. OK both of those ideas sounds good from both of . Sunday depending on weather I will race this one for the first time, With my other one that I set up but not with the set up I have now . I run a 13.5 with a 78/28 along with a set...
i have a associated t4.1 rtr with the stock brushless setup and was wondering how high i could gear it? I went from a 18t pinion to a 26t pinion and the esc and motor definatly run warmer then before but nowhere near dangerous. The battery however...

When ever you lower the gear ratio ( bigger pinion lower spur) you are pulling more amperage from speed control and battery and the motor is dissipating that energy in heat. If you have stock electronics be careful. I would stay under 23 tooth...
I've tried to read everything I can find on brushless motors.
We have between me and my 2 step sons 5 brushless motors. Varying from 3100kv to 5700kv.
The middle son is very interested in RC cars and is always asking me things.
We talk alot about...

Thank you very much, this info sheds alot of light on the subject.
It will help me make some decisions on my motor choices in the near future.
It is much appreciated.
So has anyone experimented with gearing an RC10 for a brushless system? It's been stated that the 6 gear may not handle a brushless/Lipo system so well, but how have people geared the Stealth and with what battery/motor combination? I'm interested...

For BL setups, consider the Speed Passion setup. Im looking to pic up a unit through my motor builder (shameless plug: ) They seem to be very good and competitive.
At my local track, our vintage class allows for Lipo, but still running brushed...
Okie, I have a 17.5 motor and a 5.5 motor, both Novak Brushless, the guys at RCHR are running 8.5 and 10.5, I know if I use the 5.5 it'll be too much to handle on the track on a 2wd T4.
Can the 5.5 be geared down? Enough to compare to atleast an...

You dont say if you are running LiPo or NiMh cells but...
There is a local guy over here in OZ that regularly runs a 3.5 or 4.5 motor in his B4, but he also only uses 4 or 5 cells depending on the track conditions..
The novak gearing guide suggests a 6.0 ratio for 2wd buggies with the 17.5 motor.
The XX tranny is a 2.19:1 ratio w/ an 84 spur.
So it would be something like this: (84/30)x2.19= 6.132,
Would I be able to...

I tapped the Spur gear holder, with a 6/32 thread tap, screwed in a 75 spur gear with 6/32 screws, cut the excess out of the other side of the plate, where it meets up with the slipper pad, and ground them down.
I have a HW 10.5 for my Bosscat. The motor manual says to gear for ~8.00 final drive. I can, or could, achieve this with 28/92, except 21 is the largest pinion that will physically fit with a 92 tooth spur. (I don't have any smaller spurs.) 92/21 x...

For future reference- Drilling a 5/8 inch hole through the center of the Cougar/Top Cat spur gear worked perfectly. It bolted directly onto the Bosscat slipper.
