I just got my BJ4 completed for the weekend. Excited to drive it, completed one battery pack (loose cells - IB3800's) figured out how to configure the Novak brushless controller (new to brushless) and was able to get the electronic working and servo turning good and wheels were turning. Slipper clutch was way loose, so, had to adjust that (brung my bj4 instruction manual to the track). Once I got that fixed, wow, the wheels really turned. scary fast power right out the box. Eager to put on track, ran right over and got the steering corrected and let her fly.
Mucho fast straightaway speeds. Even stayed on all 4 wheels during all the jumps. Remebering jumping tips from previous posts. Feeling especially happy with the performance, decided to wait on a nitro vehicle to race as they came around to the straightway I lighty applied the throttle. Rooster tails were thrown as I jetted down the straightaway and left the 2wd truck in my dust. rounded the corner and had to wait on car to get turned over, the gas truck caught up and we jumped at the same time and got tangled in the air.
:-( landed and noticed my front wheel looking abit off. Aye, the front A-arm snapped. That ended my practice session abruptly.
Hopefully, that was a fluke and I just landed funny from the truck intefering or the gas truck hit my car funny and caused it to break prematurely.
eh, waiting on parts. enjoy the pics.
