Thread: Help with Choosing ESC

  1. #1
    Hi all,
    I have completed a beetleweight and fitted a couple of cheap esc's, they work but the speed reduction when in reverse is awful, also I have to wait a second or two between going from FWD to REV and back again. They are ok for practise but not ideal for the arena. I am running on Lipo 3s with 20c - 30c burst. I have two independent motors for drive and steer. The motors pull about 2-4A unloaded, with a wattage of about 8W.
    Can anyone advise alternative esc's please? I have considered a dual motor esc but they do tend to be quite large and heavy for a beetle. Just to clarify I need reverse, preferably with same speed as FWD.
    Many thanks for reading and any help.

    What esc are you using at the moment? You might be able to change the firmware on it.

    I can't find much information on these. I might be possible to change these ones, but not easy. Sorry for not being much help.
    You want to get an ESC where you can disable the brake.

    I was going to suggest the Vex29 BB controllers at ~£8 but they seem to be out of stock and will be for a while. A lot of beetleweights use 10A reprogrammed Botbitz controllers. Used to be available through Ranglebox in the UK but haven't been in stock for a while. However, you can still get them direct from Botbitz; they come from Australia but the shipping can be quite quick and the service is good.

    Many thanks Jamie, Paul for your help. After more research I believe my Esc's are difficult to reprogramme. For the cost of the GoolRc Esc's, think I shall invest in a couple of new Botbitz 10Amp controllers as Jamie has suggested.
    Once again many thanks for your help.
