RE: Is 4 lbs. to heavy for a 1/10th scale car???
Good news nitrohead. Definately post pics man. I want to see your progress and YES the car handles very well with the 1/8th scale tires. I found out today under some hard acceleration pulls that the front tires went into tire shake BAD. I disconnected the driveshaft so that just the rear was pulling and the car was acting as if the clutch was slipping but it was the rear differential that was slipping the ring gear. I held the car down and gave it some throttle and the clutch bell was indeed engaging hard to spin the pinion gear but not the rear tires so out came the diff to meet mr. JB Weld......LOL. I already had to do that to my other TC3 anyways but I thought maybe because that diff was old and tired but I am guessing that the .21 has way more TQ and HP that this stock diff can take.
I am going to hold off on that chassis since it is very pricey and with a CNC machine at my job, I can machine the one that I have but with less holes.
POST THOSE PICS!
