Hey guys, sorry it took so long to get back to you. I will have to check on the hopup parts; the office will be closed from tomorrow until January 2nd so we've been cleaning stuff up before the break.
I do have some news from Travis. He said that the servo saver spring setting felt far too soft and was preventing the truggy from steering correctly. He ended up cranking his servo saver down to the point that it was completely locked up which greatly improved the steering capability. It should be noted; however, that he gets his servos for free, so my recommendation is to tighten the servo saver until it is all the way locked, and then loosen it 3/4 of a turn. If you're running the stock setting this will greatly improve your handling.
I've also grabbed a truck and will be running it next week during our break. I'll be sure to post any useful information on here in an effort to develop a good race setup.
