Motor question castle 7700kv setup

[98sierra]

I have a castle 7700kv 4 pole non sensor that has been laying around and a castle sidewinder 3. My question is anybody running this setup if so what gearing I do not know where to start with this setup

 

[Johnnysplits]

No, no , no, no, and no...not in any kind of crawler/scaler. That motor is for an onroad car/drag car.

 

[EeePee]

Gotta be more positive! 2S lipo, 14/87 gearing cause that leaves the option of a couple teeth fewer if you want. "thumbsup"

You don't know where to start with that setup? Don't start there, period! Way too fast of a motor for scx10.

It was in a vaterra ecx haha. We'll I mean I was just wanting the wheel speed. I have a tekin 45t and fxr on 2s but heck it's no fun like my old wraith. Anybody have any suggestions for the tekin or the castle gearing wise

 

[Johnnysplits]

Get a Tekin 35T handwound and put a 4 cell to it. You'll be happy.

Yeah I think this is a 45 heavy duty or something of that nature. What other options do I have on brushed motors. Any ideas of what gearing to run on this 45t with 2s or 3s. It's got stock spur and then 17 I do believe

 

[Johnnysplits]

It depends on what you want it to do. If you want crawlability and high speed, you gotta go brushless. If you want crawlability and decently quick, 4s lipo with a 35T geared 90/14. That's my setup at the moment and it's great for me. However. I will be going brushless one of these days.

If you wanna try it then go for it. Sure the kv is way higher than usual so get a large spur and small pinion. I would still expect it to cog at slow speed but it might be manageable. Definitely has a lot of wheel speed :ror:

I've got one of those motors and due to boredom I've thrown it into an scx before. I geared it like 87/12 and it was pretty quick but of course no low end torque. Not much cogging unless you really try real technical crawling. That motor tends to heat up though. I don't recommend it long term but its fun to try.

 

[98sierra]

Does anyone have a dynamite 15t. I thought about running it with the fxr it says 2s on the website.

 

[98sierra]

So my gearing with the 45t and fxr is now 13/87 slow on 2s but very quick on 3s.
