WOW sorry to hear about your medical issues. Were you trying to ride one of your R/C's and fell off?

Or just trying to feel young again showing off your once alive and well football skills to the kids?

Anyway hope all goes well with your medical professionals so you can get well soon.
As for the ESC issues, have you tried talking with Martin over at MGM? Yea I know some of their stuff is a little bit expensive, but he specializes in personal requirements for his clients, so maybe you can work out what you want with them and come up with the ultimate controllers. You can write to him at
(m.dvorsky@mgm-compro.com). I have exchanged a few emails with him already and hope to visit their little factory soon. We live in Prague now, and his shop is a few hours drive from here to Zlin, Czech Republic, so we have to wait for our van to arrive before we can take the drive over there and meet with him and his borther. Anyway just a thought. I hate to see your ideas just sitting around gathering dust, when I am sure that we would be impressed once you have something more in production or at least in a testing phase. Good luck with that and your shoulder issues.
