New idea?

[mikemaster]

Here's my new idea to improve rock crawling performance--moveable ballast. Since the battery is probably the heaviest thing on our rigs, we could make a sliding tray and slide the battery either forward/backwards or left/right using a lightweight servo. This could improve our c.o.g. when on an angle. Has this been done before? Thoughts?

if you could get the mechanism light and simple, it would be worth a shot. It seems like something similar has been tried, but I can't remember anything about it. Maybe it was just talk.

Often thought about that for a fullsize vehical. Have not seen anybody build one yet. I think batteries maybe to big to move around. Lead weights might be better? The axles would be a good location for moveable ballast.

What batteries are you using? Quite a few people that compete at the ORCRC events run 2/3 A packs.... a 7 cell pack of the 2/3 A equals just about 5 ounces. I'm pretty sure a standard 540 size motor weighs more than than. That's about 1 ounce more than a Super Rooster ESC too For the bigger trucks many will still use Sub-C's but many just have custom AA packs built that weigh less yet can produce enough juice to get through an event.

Smaller packs can be located into more spots in the truck without issues. Zip-ties are great for holding the small packs down in those tight spots.

I think it is a good idea but would be tough to impliment. Most chassies have become so small that you do not have a lot of room to play with.
