Another B-36 Peacemaker - delivered early?

[kerick]

Update: MOST of 42-13571's engines (well, motors) arrived today. 6mm 3v/40mA micros I found on AliExpress. With only one motor and one 1.5v AAA, it turns so slow you can track the flat spot on the output shaft with no motion blur. Plan is surgical-tube splines to connecct the output and prop shafts.

Next problem, figuring out what kind of coin-cells or AAA arrangement I need (be it just two in series or several pairs in series-parallel) to keep all six spinning... or maybe since the game I'm building these things for has "low" and "high" speeds for each aircraft have a two-stage switch that idles the middle engine on each wing in slow.

Just wanted to let y'all know that the project is at a dead-slow crawl but it IS still moving.

Sounds like you need a rheostat to control the motor speed. Sort of like the volume control on an old radio. You can get speeds from zero to max.
