Finally was able to run the NB48 sunday. Ran it rear engine since a lot of people here are saying that it was lacking traction in front engine mode. Had to play a little to get it working the way i liked and it paid off. The biggest improvement after playing with the shocks positionning and the brace in the rear leaving only the short one. Had some traction at the point that the car was pushing now. Played with the rear hub hinge pin postionning and helped a lot without sacrificing traction. I guess i will need to try the front engine now I did a lot of circus figure with it and only broke the tank which i received from SD to eastern Canada in 3 days(talk about great service from Tekno!)I will probably need to get stiffer shock springs too but overall i was impressed with how it was easy to go through the rutted track we were playing on. I think i will no longer need my rc8.2...
