Does anybody have a good alternative fro these esc's as they are currently out of stock
Sabertooth 2 x 10 / 12 or whatever they're flogging at the min
program some ESC yourself, SimonK files around for smaller current ESC
Wouldn't recommend the Sabretooths massively, they do just seem to break randomly. Would probably only use them in a competition machine as a last resort, personally.
These wor but only on 2s lipo. You'll need a higher rpm motor than the 1000rpm ones we normally use.
I won a couple of these cheapo Hobbyking Esc's at an event late last year, i'll be using them in a new Beetleweight at some point. They're the same one's that the Kinematic Events PTD robots use and they see some abuse. You can also run them on 3s, again the PTD robots do and they don't seem to have any trouble. http://www.hobbyking.co.uk/hobbyking...d_Car_ESC.html
I've been busing the same sabertooth since 2012. I know that have a reputation for being fragile. They're easier for a new builder to use that programming something else. I like the look of the ESC you linked, might actually buy a couple to try after I cooked the botbitz's.
Can someone please help me I'm massively confused :( I've bought 1000rpm 12v eBay motors but struggling to find a 3s esc which has reverse. I've I've looked at the 45a esc linked in this post from hobby craft but it's a 2s? Would the 7.4v be enough to power the 1000rpm 12v motor properly? I bought turnigy 20a esc but in my heist I didn't realise there was no reverse. Not looking to spend a fortune if possible. If anyone can help that would be great!
The vex ones are pretty good, need a bit of hacking but it's minimal really. Will have a look for a link unless someone else has them to hand...?
Ah god hacking?! Lol that doesn't sound easy lol
They have arrived!!!!!!!!!!!!! One step closer. Thanks Ellis!
Hi all
Looking for some info and guidance on these ESC's am I right in thinking the the red and yellow wires which get attached to the motor, it's the red wire that is the positive?

Don't forget that I believe you will need to unhook the BEC from one of them (the red wire on the receiver plug), as the receiver will not like 2 power sources (perhaps someone could chime in if I'm talking rubbish here, I actually have both of mine disconnected, and a separate BEC to power the receiver)
Actually, reading the question again, I think I misunderstood. The way the wires for the motors are connected up only determines which direction the motor goes, so in fact either wire can be positive depending on what the controls are telling the ESC to do.
If you connect them up and the motor goes backwards instead of forwards, just swap the wires over (or flip the reverse switch on the transmitter)
Lol yes Jimmy your second message is what I was looking for :) ah there we go then that will be fine, just didn't want to wire anything up wrong and damage the ESC's. And I believe I have to remove the middle wire from the connector that goes to the receiver because they have built in BEC's. Thanks for commenting Jimmy, I'm completely new to this and want to make as little mistakes as possible. Well I don't mind making mistakes as long as there's no cost implications. :)
honestly mistakes are the best way to learn stuff in this sport so dont worry about things not lining up etc
I had to redrill eight 13mm holes today because they didn't line up properly, and I've been doing this for 12 years :lol:
Jamie you need to stop working and thinking of dead metal at the same time it just leads to accidents
