Combine that with Miles CAD work for a board layout, and Gary's board printing connections, and we can have a sensor retro-fit done ourselves without waiting on Bob for who knows how many years. lol
Combine with the IRF 4110 fitted 6-fet programable infinion controllers the size of a creditcard, and you've got yourself a 100v sensored drive solution for a fraction of the cost of a castle ESC.

Just a suggestion but wouldn't these Astros have application for model heli (3d), airplanes and 1/5th scale RC cars?
If so... and anyone knows some decent people from other forums - how about cross posting to get the order wrapped up faster (quick chance the non es member before this deal price to 325.00 and pass the savings along to us )__
