Hey guys just looking for some help. My car seems to lacking in speed lately. Its fantastic in the infeild but struggles on the straight. Heres my set up. 40mm in the rear (yellows) 40mm in the front DBL Pink. 36 Pinion, 100 Spur. Diff has been rebuild, motor (Trinity Monster) has been cut (27T), and I'm running SMC Orions 4200(New). I usually charge them at 6 amps. Any ideas would be great, Thanks.
