That made me chuckle. Not being rude sorry

Advice given in this thread is very sound from many very experienced builders. As mentioned featherweights can be as complicated or as simple as you want just like heavyweights.
For example in a feather you can create your own transmission or use drill motors
You can take a similar process with heavies (purchase NPC geared motors) but again, much more expensive.
