I know lots of people asked this a year back or so, but wondering if any new batts are out that would work. I like running jrxs pro chassis and have several of them. Want to try VTA with 21.5 and LiPo, but none of the LiPo's I have found will fit (at least none with hard cases). Anybody know of a LiPo that will go in an older jrxs (not type R) without modification??

I think the YEAH racing 3200 will fit with a fully rounded case with cell dimples. Anything larger mah will be too big.

A 3200 would work fine for me. I'll be running a 21.5 in a series with 4 minute mains. Thanks for the info :)
