hi there, just an update. Electronize is around (in a fashion) although they don't advertise - Dave Mainprize, the owner of Electronize, is still running the Company. Although they aren't producing the 30 amp speed controller, I am lead to believe they are still doing the 43X which is a 15 amp one. How you go about purchasing I am unsure - however - if you do a web search you can come up with his telephone number/address.

Hi. These speed controllers are really excellent quality and can handle a high degree of voltage and amps. I use two in my vosper which each handle 24 volts. Be warned though you can seriously damage them if you reverse the polarity when connecting to the battery. There are two adjustments on them. I think one is sensitivity around the low speed response which improves greater low speed control. The other is speed range which gives you adjustment on the range of speed in relation to your radio stick throw. I have found these to be excellent high quality controllers giving excellent service and performance. You can wire in an anti reverse polarity circuit using a diode which is described in the instructions.

Kevin
