I'm interested in the MPS-1a and MPS-2a motor systems. Could you tell me what each of these units weighs?

From : Don Stackhouse

According to my slightly pessimistic digital scale:

	Motor/Gbx assembly	Prop	Total
MPS-1A	0.28 oz. / 8 gr	0.06 oz. / 2 gr	0.34 oz / 10 gr
MPS-2A	0.53 oz. / 15 gr	0.06 oz. / 2 gr	0.59 oz / 17 gr

That was for fully assembled units with the capacitor(s) soldered on, etc. There can of course be slight variations (probably much less than a gram) depending on the amount of solder you use, etc..
