1. I use a Hyperion charger so I cant help you there

2. I would suggest some higher end 2s packs, if you are new, they will let you enjoy running your truck. 6s is a total blast, but very hard on the rear diff. if you run on pavement. You will spend more time running your truck with 4s, with 6s you will spend alot of time fixing it lol :)

3. Ive never had problems with the motor, I do use Golden Horizon shock mounts, so I have a fair bit of room out back, so no engine slapping going on here :)
