1/10th Scale Saloon That Uses Saddle Pack LiPos
 

Are there any?

I don't really want to chop up my T1...

I think the T1r used saddle packs or some early xray anyway

Pretty sure you could fit saddles in most current cars with a low pro servo but motor side would be heavy

Any modern tourer can be made to fit saddle pack lipos, put end to end they are the same size as a stick pack. Easy option to mount them is the RadshapeRC Lipo Tray, or extra supports in the middle of the battery area and a battery strap rather than tape.

I can't think of any modern tourer that uses saddles and on older chassis the battery mounting area is usually a little too small to get lipos in.
