Would just one Scorpion XXL v2 be able to run a 2 wheel drive bot using 12v argos drills? Or would I be better off getting 2x Electronize 15A/30A? I like the looks of the Scorpion XXL, but not sure if I will require 2 of them (as they are more expensive than the Electronize).
Any advice/suggestions would be much appreciated :)
i haven't used them but from the spec the Scorpion XXL v2 will run 2 drills fine
The Scorpions are dual controllers, so designed for 2 motors that more independently.
They also have built in features like mixing, current limiting etc....
The Electronizes are basic single motor controllers, but rugged and cheap!
Even an XL would handle that setup. I run an XXL on 4 argos drills at 19.2v! :lol:
For this setup i'm planning on using 2 x 7.2v Nimh battery packs in series as the power source. Do you think 30A rated wire will do the job?
I should think so. Our machine is wired entirely with 30a cable, in places doubled up just to be sure. For 2 drills 30 amps should be... ample. :lol:
Does anybody know how long it usually takes to get one of these ESC's? I've ordered the Scorpion 2 months ago now and I'm still waiting. Starting to consider looking at other controllers as I'm getting tired of waiting ... :p
Email them and ask about it
Scorpion XXL finally arrived :) As far as a transmitter/receiver system for it, will I be able to use an old 27MHz one that I used with my RC car? Or will I have to buy a 2.4Ghz one? (for testing purposes).
For testing at home and such, using an old 27MHz controller is fine. For entering a battle-legal robot at an event, you'll need to get yourself a 2.4Ghz set :)
Just tried setting up the electronics. I am using a 14.4v power source and the 27MHz radio system I mentioned above for testing but I don't seem to be able to send a signal to the Scorpion. The green status light should be solid green to indicate a good signal, but I only get a flashing light, any suggestions?
Just to add, I am using the BEC system on the Scorpion instead of a separate power source for the receiver, not sure if the problem has anything to do with this.
scorpion BEC's are rubbish, your problem may be there.
They're fine, just they didn't like the power hungry Spektrum stuff. Plug a servo in the RX make sure you've got a signal at the RX.
This may sound condescending but I have seen it happen:
Make sure your RX plugs are the correct way around (Signal, positive and ground).
Just tried using the RX with a servo, but didn't get a signal. Maybe I need to get a new RX or transmitter
check your crystals, make sure they are the correct frequency and that they are secure in their sockets.
Hello, I was wondering whether to get the XL or XXL. I run 4 gimpson motors (12v I think) on 16.8v batteries. At present I use 3 electonize escs (one to operate a linear actuator). Do the scorpions just run motors or can I run the linear actuator off them as well?
I'd use an XXL in your case and use one of the Electronizes to run your LinAc
I actually just had mine arrive today, they look a lot sturdier than the XXL version 1. The case thats designed for it seems a bit optimistically named, you basically have to cut and drill all the holes yourself.
Just tried my scorpion xxl v2, very happy with the results. It seems to provide very smooth, precise control :)
