Since VTA is pretty much exclusively lipo at most tracks, what issues have racers had fitting Lipos into older chassis? I was specifically wondering about 2 cars.
HPI RS4 Pro3 - best fit would be a hard case lipo 135mm or shorter. The Orion 2400 or 3400 is a bit too long, but can be used. Is there a better battery option?
Losi JRXS Pro (not the R version) - I've read a number of posts about using a dremel on various parts of the car to get Lipos to fit. Is there a hard case lipo that will fit in this car without major modification?
