    Broke a lower-left suspension arm and hinge pin; replaced both and it's running perfectly again.

    Also took pics - will upload soon.

    Repaired the threaded rod linkage (TRA3968) that connects the steering assembly to the servo horns. Looks like it just popped out. This was the first time I've had this issue. Anyone else experience this?

    Modded my 3906 tranny to a 3908 style slipper

    Lowered it for racing, changed shock setup, put my brushless motor in, drilled a new body, and un patiently waiting on my ESC to come in

    Also I hope my tranny is now near bullet proof it now longer has 2nd gear and it has been bolted together I also put a steel idler in it

    Disassembled the transmission and cleaned everything; replaced all pivot ball dust seals, and the pivot ball retainers in the back; cleaned the hinge pins bores. Everything is very smooth and clean now! I'm trying to decide whether I want a new set of Hudy tools, FLM hybrid bulks and 1/8 diffs, or a Losi Mini 8ight.

    I blew the stock front diff. Still working but makes a clicking noise under braking and reverse. Got a couple spares laying around. Maybe shim one up real good.

    I just switched from the close ratio two-speed gearset to the wide ratio, and 1st is extremely low. As long as it doesn't flip over when pegging the throttle from a stand still, you can just hear the motor scream to redline over the hum of the tires as the truck lurches forward and tops out almost immediately at perhaps 20 MPH. Tons of torque but not much wheel speed; whether I keep it this way I don't know, but it certainly is fun to try out.

    I blew the stock rear diff in one of my maxx trucks. It lasted two more runs than the front. LOL Time to rebuild with alum. cup and cases and better bearings like I did to the front.

    I rebuilt the truck last week from top to bottom and took it for a test spin without the customary rollcage. Everything is going great untill I screw up a small jump and the chassis cracked in half. To top it off the skid plate tore in half and the bell crank shafts were bent. First and last time that's going to happen. I figured since I need a new chassis I tired dyeing it back. Rit dye, hot water and a cheap aluminum pan did the trick.

    THE AFTERMATH


    BEFORE AND AFTER


    ALL DONE

    Showing off at a friends house, attempted a backflip off of a banked corner of his track, truck landed upside down and broke the rear shock tower and bent a shaft.

    I just removed the stock steering servos and replaced them with the Hitec 7954SH - a high-torque, high-voltage servo. It's rated at 333 oz/in and .15 sec at 6.0V, and 402 oz/in and .12 sec at 7.4V should I ever get a BEC. I'm certain to appreciate the extra authority it lends my E-Maxx's steering which at times feels sluggish and and lacking sufficient holding torque.

    Did you shim the servo saver for more tension with the stronger servo?

    No, but I need to. I could hear the servo cranking the wheels but the saver isn't keeping pace. It's one thing I wish the E-Maxx had which the Revo has - a stronger servo saver spring, instead of having to shim the existing weak spring.

    Yep! I bought two springs when I was upgrading my revo to a single servo before I knew it wouldn't work!

    Geared 28/56 on 6s through a Gen2 Tekin RX-8 and 1700 kV truggy motor, on stock 3.8" chevron Maxx tires and an old Pro-Line F350 body, I hit a confirmed 44 MPH in first gear and 58 MPH in second before I hit full throttle, the front end picked up, and I lost control in a spectacular cartwheel ejecting one of the packs. No apparent crash damage after inspecting the plastics, shock shafts, and hinge pins. Who said E-Maxxes were weak?!
