Question
Bench testing motors, props and batteries

I am completley new to electric motors and R/C.

I am enjoying learing how all the different components work and scratch building on a budget.

I would like to know what equipment/instruments I need to bench test motors, props and batteries, and what is the method (from..... where do I place the wires.... to the correct operating procedure to get constant results).

How do I work out the optimum prop for the plane.

Really "bench testing for dummies" would be great.

Thanks in anticipation

Andrew

1)I only use Deans ultra connectors. Lost all power while learning with Tamaya connector
Silver lining. The plane landed itself better than I was flying at the time. I trust only Deans
2)I picked ONE battery standard-that way I am not stuck with the Mismatch/aint got that size charged delemna 3S2200Lipo
Buy a quality charger. I have a Triton and a 4 bay lipo charger.
3)A decent tach is 18 bux. never use near flourescent lights they will make it lie
4)A decent wattmeter is 40 to 50 bux.
5)A postage scale for thrust works good. Fabricate a motor mount that will clamp.
6) of course the trusty multimeter.
7)Motocalc.com Motocalc isfree for a mont, and under 40 bux
Also remember I bought in stages, so I didn't go broke!

Here are a couple of places to see how thrust stands can be made: rig one of these to a Medusa Analyzer Pro with all its bells and whistles and you will be able to read volts/amps/watts/rpm/thrust/temperature......
