T-REX 550 › Question about 5 cell vs 6 cell

My current set-up is 170 main gear with 16pinion,my head speed calculator gives me 2450...
I'm switching to the 112 main slant tooth gear with a 13 pinion,if I run that gearing on 5 cell it's says headspeed of 2620. So 5 cells are cheaper and lighter,anyone have a reason this isn't a good idea?
I do have the pinion to use with the slant and 6 cell but was considering the 5 cell for a weight reduction.
All things being equal,if geared right performance wouldn't suffer on 5 cell would it?
Thanks guys!

Performance would be ok on 5 cell. The packs would be lighter but your flight time would go down. You would also pull more amps so would have to watch ESC temps and im not sure if the stock 70 amp ESC would cope.

I also find 6s packs are much easier to find.

If you were to do it ide suggest the 12T slant pinion from the 700E.

60% of the time, it works every time!
