Thanks for the reply RDC. I know it's not going to be cheap, been thinking of trying to make one myself but I have no knowledge on cad at all.
At the moment it's taking me around an hour to install this new mod, so many wires
plus it's an 18f chip so soldering it to the mini circuit board before installation to the controller is a nightmare as the legs are so small and close together.
The other one I have only takes 5 minutes but isn't as good so I need to get moving with the new one.
The one you have posted there would be perfect, it's a different chip though
