I'm playing around with Arduino and NRF24L01 2.4ghz transeivers and am looking for a cheap 0-4-0 bare chassis with motor to sit on the test bench. Anyone seen any or has one for sale? (45mm)
Thanks for the info, I've ordered one of the biaxial units. I'll find sommat else to do for 6 weeks! It's only to have on the bench while I'm writing the arduino code.Someone on this forum recently posted a thread about these inexpensive motor blocks from China that can be adapted to take large scale wheels. The all plastic geared version of the motor block below has 3mm keyed shaft which will take typical large scale wheels. There is also slightly different all metal, semi metal and all plastic geared versions that have a thicker shaft as in the original post mentioned which need drilling out for a 3mm axle.
1.5~6 volt (two wired in series will suit 12 volts. 94:1 ratio is slow but so too are some prototypes.
I suspect the gears will wear quickly if pulling much load but they would suit light running.
