hi there Neil
Sadly, I tend to agree with what has been said - accidentally you may have fried these speed controllers. Before condemning them to the bin though - there are a couple of things to try just to ensure that they are 'fried'.
Have you tested the motors without the speed controllers? straight off a battery. and do they work?
Do you still have the Mtroniks speed controller which came with the model? If so, connect one motor up to the speed controller without fuses - making sure you have the leads the right way. If you are unsure - the link I previously put on to the Mtroniks website will show you which leads are what.
Then, plug this speed controller into your receiver and does it work?
Then, once happy knowing that the motors and everything else works - you may be able to come back to the speed controller which blinks all the time. If it is blinking, have you tried this speed controller coupled up to a different motor/a smaller motor.?
Normally a solid red light indicates no signal from the RX.
The only thing I would really say - is - I am not a personal fan of these type of fuses being put in between the speed controller and motor because I have come across one or two in the past of this type which have a built in resistance.
