I'm not trying to be harsh I just rember when I was 8. Building my model train set ho scale and I to figure it out . Now days its all pre assembled and theres hardly any thinking involved . I like nitro and gas RC because it keeps ya on your feet! Lol
Yes, I've got also savage x and I've been using it for may 4 gallons and to much jumps and high speed run but only last friday the A-arm was broke, but its reasonable, I understand why it brokes. and now I've disassembling my savage X for full maintenance. Changing all bearings to AVID BEARINGS, including the stering servo plastic bushing change to AVID BEARINGS. TAKE A LOOK-
If your wheels are shaking maybe it's because your battery is way to weak ! Upgrade the battery to a actual rechargeable battery pack. They are heavy and drain batteries quick
Hope this helps !
