I'm also new to 1/10's, I bought a B44.2 kit at the start of the year and built it to kit specs but never used it due to no 1/10 racing at my track. I also bought another used roller with an avid chassis which i have started to run at my track. I think it has been converted from a B44.1 to a .2 with the avid chassis and carbon fiber rear hub blocks, and the shock towers, top plates etc are slightly different to my original B44.2 kit.
From the pics below can any of you guys tell me exactly what i got.

Also another problem i have is the rear dog bones keep popping out when landing big jumps.

Any help would be appreciated
