Motor/Prop Data

This page has several tables of data such as weight, static thrust, current consumption, etc for various motor/gearbox/prop/battery combinations.

I built a very simple rig to measure static thrust. What's missing is the RPM data.

Astro Firefly with 16:1 gearbox

Astro Firefly 16:1 with GWS 10x8 prop
Battery	Batt Mass (g)	volts	Thrust (g)	Current (A)
Li-Ion 2x650	44	7.2	58	0.530
NiMh 7x300	57	8.4	76	0.660
NiMh 7x150	44	8.4	67	N/A
NiMh 8x700	105	9.6	98	N/A

Astro Firefly 16:1 with WesTek 9.7x4.7 carbon prop
Battery	Batt Mass (g)	volts	Thrust (g)	Current (A)
Li-Ion 2x650	44	7.2	44	N/A
NiMh 7x300	57	8.4	59	0.470
NiMh 7x150	44	8.4	54	N/A
NiMh 8x700	105	9.6	75	N/A

Same motor/prop, but powered with an adjustable power supply instead of batteries:

Astro Firefly 16:1 with WesTek 9.7x4.7 carbon prop
Volts	Thrust (g)	Current (A)
3.0	8.5	0.100
3.6	12.0	0.120
4.8	23	0.210
6.0	36	0.310
6.2	38	0.320
7.2	46	0.370
8.4	64	0.510
9.2	76	0.600
