Hi Paul, Thanks for the replies, I was going to email you again but thought maybe I should just post it up here so that other people may get some benefit from your and/or other people's responses.
If you could email a schematic that would be great (you should have my email address). I noticed the Wiki links were broken and it made me so mad that I used my awesome karate kid skillz and broke a chair.
Once I have the schematic I'm going to make a crack at a throttle circuit modification and post it up here for review...buuuut, If anyone already has one availible for these or similar voltages ranges that would be AWESOME!
