i just got done doing that. it was only a small jump and it was hard to "thread the needle" on a jump only 2 ft wide at 20-30mph, but the truck handled very nicely. by the way, the tires have been inflated for nearly 12 hours now and have not deflated on their own yet. this mod has lots of promise. here is what i run:
i painted the body myself. the truck started in 2005 as a stock 14.4v emaxx. there are only a handful of origional parts left and i had to either modify or custom configure a some of the parts in this 16.8v style emaxx. i still run the truck on a 14.4v system though. i use a novak HV-MAXX brushless motor. i set up the front bumper in a different orientation as to protect the truck better than it would in it's stock location. what i did was turn the mount brakets upside down and swaped sides so the bumper is relocated to become a brush guard in front of the skid plate.
i have a highly modified 14.4v version of the steering linkage that does not have any servo saver because i can not find a full set of the 16.8v version steering linkage. i use duel HiTEC HG-5955TG titanium gear servos for the steering. it is very responsive compared to what traxxas has to offer in the stock 16.8v emaxx RTR.
