oh yeah whoops!, the drive works fine, so does the hydralics, i had to start wiring from scratch to get it working, never found the fault of why it wasnt working before, and fit new batteries, but it seems to work well, i used all the old panels as templates to make the new ones out of polycarb, its starting to look good now but i still have some panels to finish. so if i wanted to use this in competition i would have to bin the this current setup and go to co2? and wondered how much work was involved in converting it
