Blender is on a distinguished road
Default Quick build: Lesu MCL8 Wheel Loader

Gonna start dumping more content here since I miss the heyday of this place and PMD's forum.

Acquired a kit a few months ago. Been together and tuning on it for a while now. Barely any customization on this machine. Chose green and Grey on a whim and later added the decals. Built box-stock, swapped all the electronics and slapped in a Jeti receiver.

Pump ESC: Castle Creations Talon15
Drive ESC: Fingertech Tiny ESC
Pump: Stock with included brushless motor
Valve servos: Stock
4 spool valves (including one aux)
Selectable diff locks
Radio: Jeti 10 channel

On to the pictures:







Electronic space is super tight. This is the best I could do for fitment. All servo loads shortened and labeled. No light/sound controller now, but will add a compact light controller in the box above the cab. The jeti ESCs i love just won't fit. Instead I added a brushless rpm sensor and their battery voltage/current/capacity sensor. 2S 2200 mah pack fits, barely. Run time is around an hour.


More about how it runs and a bot of a review:
Parts quality is very nice. Virtually every parts is steel or aluminum. Fitment is good. The countour machined portions of the engine covers and tub had some chatter making paint prep more work. Overall very good. Fitment is well figured out. Every nook and cranny is used.

Hydraulic system runs a little hot if pump is allowed to idle full time. Start-stop of the pump isn't smooth due to sensorless brushless. A biddy recommended swapping a brushed motor. Still looking for a drop in option. Valve Servos are loud, but no jitter. Hydraulic valves have a lot of deadband. Paired with the jumpy start of the pump made feathering the controls nearly impossible. It is all fixable though. Pump start was smoothed out with the talon ESC. Servo curves were made for each valve to take out the deadband. Pump RPM was controlled to ramp up fast, but not overrev. Walking a narrow line to get good feel. The sole remaining shortcoming is the sole steer cylinder is a little on the small side. Having asymmetric steer force, the stiction in the cylinder is noticeable. Not as smooth as a wedico loader.



Drive is a small brushed motor. It is a little low on torque when climbing steep obstacles. Maybe my ESC choice is to blame. I'll search for an alternate to try, but it has to be small. Steer angle could be improved too. Included diff locks are great. The front is a little finicky to setup.

This machine is usually used to move Jersey barriers. I should add side shift via the aux hydraulic port.
