Calling All Brainiacs!

If you want a good reference, you woul need a killer controller to start with.. only controller i know that is capable of pushing i that far is the kontronic 63V. it´s not impossible to do though, but i don´t see it happen..

The constant voltage test can be calculated on paper, the only thing a dyno run would do is confirm the motor is in spec. On a true battery source, you would get useful info and real world #s. Batteries vary, but you need a random lipo pack to do the testing, and use same pack for every motor that uses that voltage range. Lipo packs are build to pretty strict specs and wont vary near as much as a Nicd or Nimh, so I dont ever expect to see a "matched" lipo pack for sale.

Not true.

First of all, not all motors are tested using the same standards. The Feigao motors are given their Kv rating "unloaded" whereas the NUE, Lehner, and others are given their Kv rating "loaded".

A dyno could be configured to provide useful "torque under load" info and "current draw under load".

Correct, but you can calculate that info loaded and unloaded. You dont need a dyno for that. They will vary from real results slightly due to impurity in materials and build technique. They are close enough that some manufactures use these specs. These companies know these #s way before the motor is even built.

I didnt say it was easy, but its useless info IMO. Its like testing a full scale engine on a dyno with freezing air in the dyno room...makes great #s, but isnt real world.
