Diamond Dust Launching
A few of us routinely launch our Dusts from 3 wheeled dollys made from old airplane landing gear and a piece of wood. We have hundreds of flights doing this- it works every time and you can be as far away from the dust as you like. The dust lifts off almost immediately and the dolly rolls only a few feet after that. We run sport 45-50 size engines (webra 50, supertigre 45, OS 46) and have a ball while "only" going 100-120 I guess. I'd be happy to take a pic of this simple dolly and very minor mods to the dust if you like.
