I ran 4 runs back to back, with my current 300g batteries (Turnigy 5600) and a 325g SMC 8200 and didn’t notice any noticeable difference in lap times. I already have 60g weight under my ESC to offset the 300g pack so I decided it wasn’t worth it to keep messing with the larger pack.

It did make me want to invest in a better battery that weighs less though, and see if I can move some of that balance weight inward.

I will say this.........most of the A-main driver's ran higher mah packs!!!!!
Cleveland ,snowbirds, southern nationals , roar nationals all run 5 or 6 min heats and mains . So that’s where I see the smaller packs being used in the Amain cars that I know . But reguardless of what usgt drivers are using , if it works and is preferred in 17.5 why wouldn’t it work in usgt where the power demand is lower ?

a 21.5 will have plenty left after 8 minutes even with a 4200 pack, I ran 8 minutes with a shorty 4,000 pack with my old GZ2 with not that much drop on voltage , with the same car with a 5,000 shorty pack ran 6 minutes with a 5.5t motor. In 21.5 is all in the mind if you need a high capacity pack I go by the lap times of I don’t see a drop on the last minute or so of the run in the lap times then I don’t worry about voltage .

Smaller capacity batteries are usually only at a disadvantage in outdoor settings, on tracks over 120-130ft in length.

If you are indoors on American style tracks, the smaller batteries are usually good enough to be competitive. A little more corner speed at the expense of a tiny less punch.

Both methods can win races, I would say run what gives you the best lap-times and consistency over the length of your race. The clock won’t lie. For some, that will be a bigger battery, for some, it will be smaller ones.

I used to do 100+ lap practice runs using 5300mah packs. I would be within .02 seconds, of my hot lap, at the end of a run.

There's been a lot of discussion here lately about front wheel drive vs. 4WD. I don't know how well FWD will work in USGT, but after last week's race I can DEFINITELY report that FWD with a 4.5T motor does NOT work well at all.

Step up to a 3.5, then all your problems will disappear 😳......😂

Ive ran the Reedy 8200, and 6000 packs in USGT, as well as EAM 6000....and all had the same juice for the most part in a 6 min race on CRC Carpet... 2 of the tracks Apex and Pro Level are good size, and the 3rd was med SIRC... the biggest difference was weight... having the heavier pack took away the ability to put the weight where you want it(TC7.2)…

Reedy 8200...328g
EAM 6000...305g
Reedy 6000...267g

OK, So my buddy and I are going to be running USGT this winter. What are the go to motors? It looks like Rotor Ron is selling the R1 V16 and V21 and the Fantom Icon Torque. Are these the best? How is the Reedy S-Plus?
