Here is my review on the ET410, I am happy with this Truggy and at the same time disappointed. I happy in the fact that it was an easy build and the truck is easy to drive and handles great. I’m disappointed because after about the fourth race on this truggy the following parts have broken( I am a seasoned racer) ; the differential outdrives in the front, front bulkhead and shock tower, servo Horn, and shock caps. Now I have seen that they have released “revised” parts. My guess is that there is an engineering issue with the composites that they are using. You’d think after dropping $429 for this kit that you wouldn’t be replacing parts after the third or fourth race and you shouldn’t be spending money on upgraded parts to replace the weak ones again after just dropping $429. Other drivers at my track are having same issues. I called Tekno and they’d advise me that it would take up to two weeks to get warranty parts and typically they deem racing as “abuse “ on this vehicle, so basically they are not going to replace their flawed parts because you were being abusive to this truggy because you’ve been racing it.
