Battery swap/pit stop.

Similar to how a pistol holds its clip in. The problem is reliability. It may drop the pack during a race and that wouldn't be very good.

I should note $250 canadian.
.060 lexan...I'm not sure it could handle the weight of a pound of lipo, on a off road track. maby I'm wrong though.
As for through pistol grip idea...Reliability..that's why it's not an option.

make sence?

very close

First the body will have to be made differently to cover the electonics but leave a portion of the chassis exposed. The lipo would have a hard case, with some sort of female bullet connectors, most likely at each end. A small base, attached to the chassis would have male bullet connectors pointing upward. Use 4 steel round posts on the base, one at each corner that will go thru a corresponding hole in the hard case. That would keep the pack in place front-to-back and side-to-side. A special over center style latch would hold the pack to the chassis and when unlatched would lift the pack off the chassis to aid in quick removal.

I have the latch mentally designed. The molded hardcase would require a bit of design, but could be a 2 piece item that just bolts together. Maybe some foam inside for impact assistance? With careful use of materials weight could be kept down, maybe not as light as a conventional tray though...

ding ding ding... I think we have a wiener..I mean a winner.
very very close. I think your on the right track...

I would post some pics but there's still testing to do..
and try to figure out how to lower costs.

I believe my design is less complicated and more efficient. I just got off the phone with someone who will be using a CNC mill for my top braces. We may also use the mill to design a clip system rather than buying one and modifying it to work. It has a saftey latch to nearly eliminate any possibility of dropping a pack during a race and I have decided to use my RC10 as the platform. I run the RC10 daily and will be able to perfect the system. I jump and run a track in my backyard so it will be solid and reliable. Hopefully I will have videos up shortly once the system is completed.
