SX - Lipo Chassis?

[JonB]

I have an original CAT SX (Lipo Version) which I am dusting off after a long while! I would like to change the chassis to one that can take lipo batteries with the standard locating bumps on the bottom.

Do both the U3480 SX and the U3591 SX2 chassis fit the original CAT SX and if so is there any reason I would go for one versus the other? I'm looking to do do a mix of indoor and outdoor racing.

Cheers
