ok, so joe might know a thing or two about RC trucks.
I took your advice about the pump , I have replaced all Tamiya electrics.
The post man showed up this morning with 3 big 12v esc,s and a 11v lipo battery.
2200 battery so its nice and small and fits nicely in the cab but will be interesting to see how long it lasts, hope fully around the half hour mark or more.
made a quick video of the truck lifting the bed unloaded then fully loaded with around 5kgs of dry dirt, I am more than happy with how it works
now I just want it to stop raining so I can have some play time.
