I have put the stock system back in for now

Fitted the Mamba X and 2400kv motor, this time no numpty left the pinion cover off, so all good
 

 

 

[Ag100]

Fitted some new Vitavon hardened steel outdrives to the front and rear diffs, also used some of the upgrade Losi LOSB3569 10t diff hardware (supposed to be stronger better than the standard), rebuilt the front with 100w diff fluid and the rear with 60w, also have the parts for the Center, but will have to do that another time.

[Ag100]

Fitted the Vitavon racing hardened steel outdrives to the Center diff, rebuilt using the stronger 10t gears and refilled with 500k oil.

Ag100, how did you get the stickers off of the roof and side panels?

Mine is a gen1, so stickers are literally stuck to the body, but I’m not sure if the newer ones are lacquered on?

Did this a few weeks back, new Vitavon Chassis and centre brace fitted to the Lasernut.

Fitted a mini digital Motec screen to the Lasernut, it takes a feed from the ESC, so shows real-time throttle input and elapsed time. A guy called Scalebuilt on Instagram/Facebook makes them along with many other really good little scale bits, and he builds some awesome trucks too.

Bought a (well) used Lasernut a while ago and have been slowly working through various snags:

1. Wheels working loose and destroying the very shallow hex sockets - fixed by aralditing the drive hexes into the wheels and clamping with a G clamp until they were set.
2. Driveshafts dropping out of the differential cups - fixed by adjusting the droop control bolts on the lower arms.
3. Wheel-end hardware working loose (king pins on the front uprights mainly) - fixed by replacing the 16mm bore shocks with the rebuilt originals because the big bore parts were only allowing the buggy to use about 10mm of the wheel travel so punishing the wheel ends.  You could see on hard bumpy ground that all the travel was coming from the tyres deforming which in turn made it unpredictable to drive.
4. Rear wheels working loose and a propensity to roll when cornering - fixed by reducing the rear wheel camber from "some" to "none" at ride-height.
5. Directional instability at speed on uneven terrain such as rutted tracks - cured by reducing the front wheel toe out to slight toe in.  This was measured using a piece of string tied to the front bumper and wrapped around the wheels on the axle axis.
6. Made an aluminium roof because it seemed to take a roll on every trip - fortunately fix 5 has made this less likely.

It's fast, much faster than my Axial Bomber and suited to very different  terrain.
