Re: Lindeberg R/C Quarry
That's a really big move! You are not far from Lebanon where Cabin Fever Expo happens, hopefully being held again in January 2022.

Re: Rc bus
Well, here are some pics of buses in Panama a few years ago. Seems individuals own the buses and contract with government to provide service throughout the country. Some very cool & unusual ones! ...

Re: Ertl Ford 7710 Tractor
To make an "electrical differential", wire the two motors in series. When one wheel senses a heavier load (usually the inside wheel when turning) the other wheel will speed up. Of course, you have...

Re: Valmet 931
Really like the geartrain - nice work. 3D printing has really added to modelling - from making actual parts to making molds. Awesome stuff!

Re: Pump gear what if?
It would be very difficult to flow test the pump in the machine, especially since the radio mixes the valve opening and motor on. Best to remove the pump/motor and wire directly to power source but...

Re: Pump gear what if?
I believe the gear material has more to do with longevity and wear than performance, if all dimensions of pump housing, gears, tolerances, etc. are equal. Hydraulic pump efficiency is determined by...

Re: Pump gear what if?

Re: Grey milky fluid
Grey/milky hydraulic fluid often means water is getting in somewhere. Could be high humidity getting in through tank vent or filler cap (does it have an o-ring that is defective?), etc. I presume...

Re: Euclid R-62 dump truck
