If brushless no you can't. If they are brushed motors it's possible but they need to be matched closely otherwise one will run faster than the other. Ideally you need to try the motors side by side measuring the current drawn and speed. If you have a local supplier with several motors available this may be possible but not on-line. The ESC will need to be able to supply (ideally) double the stall current of both motors. If this is not on the label with the motor you can connect one of them to your chosen battery with an ammeter in series and briefly grip the shaft between two pieces of wood and stop the motor. The reading when stopped is the stall current but this should be for a max of 1 second to avoid damaging the motor. Multiply this reading by four and that is the max amperage for the ESC. It may be cheaper to buy two ESC's and use a Y lead to connect to a single Rx channel. This will also lessen the effect of using two identical but possibly mismatched motors. Hope this helps Dave
I have used this type of motor and they work well. If you are after torque then a five pole motor will give more. You are running at excess voltage so they will exhibit some stress if run at full power for any length of time. You should measure the current at 12v to see what is being drawn, I believe mine when connected and running free used to draw about 2.5 amps on 12v. It will be considerably more under load. I used three 0.1 uF capacitors across the terminals and case as they will spark at the higher voltage. Do also make sure that all your (dirty) power wiring is well clear of any servo wires and the rx and aerial. They can be quite current hungry and I used an Electronize ESC on each motor. Any good 20/25 amp ESC will be suitable but if you are using two and they have a built in ESC you need to remove the red (+ve) wire from one ESC lead to the Rx. Good luck and please post details of your final choice and experience. Dave
Hi Sonar I suggest you try maplins http://www.maplin.co.uk/. Look under components/capacitors and you want the second page ceramic capacitors 0.1uf. If you have a local outlet it will be quicker. You do not need a dual ESC two identical ESC's is the way to go. If you are considering Mtronik look at http://www.mtroniks.net/cat/ex-demo I have used several of their ESC's and they work well. The ex-demo refers to ESC's that have been tested to spec, so you do know that they will work. Dave
