Just got my Savage Flux last night, and the PolyRC 5000 packs slipped right in. All I have to say is WOW!! I couldn't ever get my emaxx geared so fast, so I had no idea how much power the MMM system really has!
It does wheelie much too easy at any speed on 6s and the stock 20t pinion. I never got it fully opened up. Pinion came loose after a few minutes too, and I wasnt too happy with the stock pinion mesh. Now I just need to get Mike to make a motor plate that can hold a Castle Neu motor, because the Flux only holds the can with the stock motor. All they did was replace the nitro motor with an electric motor bolted down, pretty smart on HPIs behalf.
