i doubt you can get the rear wheels off, if its like other tycos. what i do to get the rear shocks off the diff is take the phillips bit from a combnation scredriver kit and put it on/or in the screw then turn it with pliers........slow to get off but works. the nikko remote will most likeley be reversed on the controls to, thats how its been for me when i tried.
i passed up a 49mhz hopper pretty nice lookin on ebay for pretty reasonable since i really didnt need one, but you could consider buying one of the ot so nice hoppers or whatever in 49 mhz and use that remote???
175 bucks already........dam, i knew i shoulda bought that mint one!!!! i like the looks of that turbo nissan truck just as well as i like the bandit really
