For all those having problems with inconsistency about the car, ive found the problems. You need to replace the shock bladders every day you run. I fond that they swell up and are a pain to rebuild as well as not performing the same.
Also for those struggling with the aggressiveness and edgy steering, I found running the shorter servo arm made the car a lot calmer and consistent.
Right now im running a tamiya servo saver with aluminum horn insert which is the same length as the short servo arm included with the kit.
