35A ESC + 3000KV.

What voltage are you using? 7.2v or 11.1v ?

I have the RC10B4. (2wd)
before i use 3000kv @ 7.4V -> Spur:78, Pinion: 27 ... FDR = 7.5
now i use 4300kv @ 7.4V -> Spur: 78, Pinion: 21 ... FDR = 9.6

for your 4wd , i suggest FDR ~ 7.5 to start.

DF03's internal ratio is 2.93, so its very high.
you will need a small spur or large pinion to make it go faster.

20/82 , 3000KV.

your current setup: (82/20)x2.93 = 12.0 (FDR)
to get to 7.5 (FDR), you will need: (82/7.5)x2.93 ~ 32 pinion.

you can try pinion from 27 or 28 first.
