XRS Rocket Rigger Design Project

[questtek]

I came up with an interesting concept for a new design rigger. The pictures show the basic concept but it is far from complete. I presented my design ideas to Mark, Stephen and Boyd who thought there was some potential merit but a lot of engineering remains. The tube provides an interesting form to work with since it is very easy to change components. I have both Castle/Neu and Scorpion outrunners for power. To eliminate torque roll I designed a gear assembly that has 5 mm shafts supported by high quality ball bearings. Thus, a single motor provides CW and CCW shaft rotations I think the key to success will be the ride pad design on the bottom of the nose cones.
One other advantage is that the tube diameter I am using, about 2.6”, will accommodate anything from small, high KV outrunners to giant Leopard 5692 , 1340KV inrunners. By using longer tubes 6, 8 and 10S LiPo pacs can be used. Anyway, this is a works in development progress.

Very interesting Design, will they be for sale or is it just a project?

Only a project at this time. It it does indeed work it would be a very, very simple kit with a carbon fiber tube, nosecone, machined endcap for mounting rudder and shaft (s) with sealing o-ring, and sponsons. We may start with some available fiberglass or CF sponsons since their design and angle of attack is critical. SOmething like the sponsons shown in the picture below

This reminds me of a "rigger" built by Mike Mayer for the 2002 LA SAWs. He used carbon fiber tubing and flat stock. The photos do not show it, but the tub was attached to the sponsons by a suspension not unlike an R/C car. Lots of cool ideas were used, including a steerable "outdrive". It wasn't very fast, but I don't think it had ever run before that event. Mike's day was ruined when his truck was stolen at the lake....

Thanks for taking the time to pass that along, quite interesting. His drive is quite unique with a far amount of machining to fit it together. I will do some research and see if he posted a build site or any additional information on a tube-based rigger hull. I would like to see more of that type of innovation at the 2012 FE Nationals held here at Legg Lake in Ca.
