    Don't be surprised if it's the 75mhz radio giving you fits.

      I know you guys are just ribbing each other. Personally I think it's funny. But some might not think so. Can you please put some indication that you are joking so
      others won't think this is a hostile forum? Thanks...

              That is pretty ingenious Chris. I have been thinking of building something like that for testing actual KV of motors.

                  Why you need a test stand?

                    I want to see if the motor or batteries are bad don't want to run the motor without a load I am going to use a airplane prop for the load and some cooling !

                      Chris the prop really depends on the motor and kv. You will have to have an amp meter and test with different props. My motor was a Hacker outrunner that could swing a 12" prop at 10s and a 16" prop on 6s. It all depends on your setup. These small boat motors I would start with a 4.7x 4.7 prop and see what you get. They make prop adapters for 5mm shaft so it's easy to mount an airplane prop on the motor. You might have to get an airplane motor mount or you could make your own out of aluminum.

                        Chris, Ive done prototype RC plane design stuff for years...loads of testing..gas to electric, prop to ducted fan....no need for the strut and flexshat, unless your wanting to test those too...which would be a really nice feature to have, specially for us "SAW" guys..comparing load/drag between different struts,shafts, couplers etc ... you need an adapter to fit the prop shaft, alot of airplane props come with different sized hole inserts to fit multiple shafts...as Mark stated a 4.7 x 4.7 would be a really good starting point....a inline voltmeter thats been shunted to do up too 300amps and you got the ultimate test stand....

                            Chris.
                            Here's my old set up for testing motors, batteries, ESC's etc. A bit industrial perhaps, but with the watt meter logging all the Volts, Amps, Mah used, watts, peak power etc, its very useful. Plus you can watch the numbers change in real time while you are testing. Great for discharging packs too.
                            Like DJ said, all you need is the airplane prop adaptor on the motor.

                              My local Hobby shop gave me a 12 X 7 *!**I guess that's a poor start LOL, I never thought of mounting the prop directly to the motor *!**Hmm. I will make the prop adapter out of some alum. round stock I have . I built the test stand to test different motors and I kind of winged it as I went along but I see your point, I might just get a ducted fan unit to try as I have to build a shroud for my stand thanks Chris*!**

                              Going to get another meter as I sold the one I had they are cheap enough, I do have a clamp on DC amp meter but that would be to awkward I will also look into the ducted fan thanks Chris
