Crawler/trail truck you can run them anywhere unlike racing is only at the track. I take my daughters, trucks and the dog hiking. I always hear I've never seen that before. TRX4 is a lil to heavy for my taste and crawling/trailing style. It struggles on our trails but it is a decent truck. I I were to ever get a traxxas I'd go for the Sport version. Lighter and less gadgets to break. I had a Losi Comp years ago but I have thought about the new SE and how would it do. Crawling for 2-3 hours and go home. Great day of fun. Racing all day event and fellow racers that never marshal sucks.
