Also, isn't stock and 19t 4-cell quite a bit slower than 6-cell? Noticably IMO.
Are you talking about 19t 4 cell being slower than 19t 6 cell?
If so - of course it's SLOWER, it's powered by 33% less energy.
Nobody in OVAL is really running 6 cell 19t that I know of (at least out west),and actually 19t in OVAL died w/ the ILLEGAL 19t motors last year, and pretty much moved to 10.5 Brushless.
A 6 cell 19t would run about as fast as the best 4 cell MODIFIED times I'd bet..much like the 10.5's do when running them on the 3200 LIPO packs. THEY ARE ALMOST INSANE.
