Castle sidewinder 4 problem

[Slapnuts803]

Just replaced the stock motor and esc on the Losi 22s rtr drag car, and installed the Castle sw4 paired with the 7700kv motor. I have played with the programing several times but just can't seem to get off the line with any kind of power. You can tell that the motor will start to wind out towards the end of my run. Is there a setting that will fix this issue?

Maybe the punch control? Thats basically a delay for until full power. Another thought is the cyro drive maybe.

From what I've seen your set up isnt ideal. You really need to be running something sensored. I'm guessing you're getting a lot of cogging and thats why its not getting off the line very fast. Running sensored will help with that. Running higher C rating batteries will help. a SW4 isnt really up to the task either. Most of the fatsest guys that are local to me doing no prep are using 160-200A (basically 1/8 scale) ESCs that are fully programmable so you can set throttle and breaking curves etc and they are also generally running higher KV motors than your 7700kv too although the 7700 isnt to far from what they are running. The 7700kv is basically the same as a 5.5T motor. Locals here are running 2.5T(roughly 11900kv) to 4.5T(roguhly 9300kv) motors. They also usually use between 80-120C lipos also.

In terms of you just getting off the line faster with what you have it might help if you had some video footage of a launch so we can try and see if we can identify the exact issue but my initial thought is you need a bigger ESC and you need to run a sensored set up.

Thanks for the feedback. I just ordered the Castle copperhead because it's sensored to go with the sensored motor. Do you think that will help? i do know that it will run much smoother with a sensored set up.

Thanks. I think I have it set at 30% right now. I did notice a little difference when i went from 40 down to 30%.

If cogging is your issue (I can only speculate) then yes the copperhead will work better because its sensored. That being said its still a 1/10 scale ESC so i hope it holds up. When you start really pushing for more and more speed and you start using advanced timing, lower turn motors, etc you'll likely smoke it at some point. I know guys running Maclan DRK 160A ESCs which are specifically designed for no prep that smoke those from time to time. Will the Copperhead hold up better than a SW4? Yes. Will it hold up like a Maclan DRK, Tekin RX8, or Castle MMX? No.

Gotcha. Thanks man really appreciate the quick responses.
