well i got my hobbywing sc-8wp and my savox 1256-tg in today. Im gonna be runnin on 4s and my question is do you think the stock drivesahfts will hold up.I used to have a 3906 with a titan 775 swap, but i understand this will likely have 4 times the power of that. gonna get rpm bulkheads and upgrade to the 17mm splined hex's. the motor is a 4076 2000kv 4 pole with a 2800 watt max rating. But as a precaution im gonna upgrade all shafts anyways, then i think ill be good to go. Do you?thanks
