ok I was doing some testing on motor temp/esc temp, and trying to figure out the whining sound. I did in-fact find a few things not to my liking on a $600 kit. Do note this is brand new. 1st off I found that my passenger-front drive shaft is warped about 2mm-3mm. This is causing quite a vibration. Possible whine candidate. And before I mention the 2nd issue please do understand I'm not a newbie to building r/c's I have built and flown helis for about 10 years, and been building cars since I was 18.. The center diff gear has a wobble to it. I built it as I do all diffs tightening screws down in a cross pattern a little at a time to keep from warping the plastic. and there is a wobble in the pinion gear also. Put both of them together and there is another possible culprit to the whine. I am disappointed in the drive shaft and the center diff gear, both are warped and came from the factory this way. I am picky and have little to no tolerance for warped parts. LIke the new set of Sweep truggies tires I got the premounted... they are absolutely terrible. Warp'd to high hell and back.. Sweep USA was like oh well sorry to hear that.

This is simply a failure of quality assurance on Tekno's part. Over the years I have found a smaller, new, company always ends up sliding down this road. Greed takes over and quality is surpassed by quantity. Cheaper materials creep in. I hope I'm wrong and Tekno stays on top of their products. Firstly let test there customer service and see if they will replace the warped parts. Hopefully i'm not out the cost of replacing the parts. But nevertheless I still love this truck. And look forward to racing it.
