I wouldnt think the settings for the dtx.18 and velocity .17 would be the same because the dtx is made by o.s. As for the the truck wheeling, mine would wheelie like crazy on asphalt with the stock tires but then i figured out the slipper was stuck together and havent been able to get it to do a wheelie since. Im afraid my diff is going out but it just keeps going. Im just gonna run it till the diff is completely dead if it even happens(since ive tightened it (half a gallon) i havent had it slip but it does make sounds.....oh well). Just today i took it to the local track and man was it a blast. There were 3 other people there and we were doing so crazy jumps on the triples. One guy had the new monster gt and he beat the crap out that truck and broke nothing. I must have crash 20-25 times(bad crashes too) and it took it in stride. Only broke the front body mount.
