Built this kit last weekend. I ran it this Wednesday night club race. I qualified 3 in the main with a full main. I haven't driven a 4wheel in about 8 months Btw. And I have to say that I really was impressed. The car built very well. I had no problems what's so ever. The gear boxes are quite tight like everyone says. I just used a 3 mm tap to start the holes and the grease with the screws. Perfect fit! Plus ( no missing parts!) like others have been having unfortunate luck with. Looking forward to this car only getting better!
