Exalt's motor load test stand looks suspiciously similar to the load master: https://teamexalt.com/motor-load-test-stand-exa9312/

It probably is. He wholesales his products to many different companies.

While I do some OEM for DRC, the Exalt product is not mine, nor made by me.

Copy write issue? What a bunch of losers! There is not doubt that they reverse engineered your design. They suck so bad!!!

While I appreciate your support, my product is not covered under any patents or copyrights. Point of fact, you can go through this thread and get all the info to make your own. I only hope that those who want one will still be enticed by all the pretty colors I offer! And the amazing customer support I provide! Yes, I am biased, but I do give great support.

Note that as opposed to a patent or trademark, copyright exists automatically (in most countries, but not all). No need to claim or register it. Regardless, trilerian has publicly expressed eagerness to share, for which many of us are grateful :). It's getting into nuance, but copyright covers the expression of an idea, not the idea itself.

None of that stops people from having contempt for those who abuse the intent of that. ;)

The question is if the costs of a patent can bring up enough money, within the RC world that is difficult.

My idea of an FDR meter had many follow ups by other home brewers and recently a true MR33 commercial product. I had interests by Muchmore but at the end they went up another way to keep control on an equal performance. For me it still gives me a proud feeling, for sure with the knowledge 3 cheating ENS top names were send home. And of course the people around me know I started this.

In the case of the load master it wouldn't be patentable anyway as there's too much prior art.

I wish I was still selling Electronic Components, I could've helped you save a lot of money getting those resistors and what ever else component wise you require. I always think about getting back in, but I think I took a challange that might be impossible lol. Like some have pointed out, your product is protected since it is published. If I was that other company, I would contact you ASAP and work things out. Example, a certain person in Israel copied a design from a person in the U.K., but the person spoke with the original designer and they came to an agreement. If you need any electronic components send me a PM and I'll see what I can do since I still have contacts of my suppliers.

I'm looking at testing a 25.5 and was wondering what turn motor I should use for a load ?

I always suggest using the same size slave as the motor you are testing. But a 21.5 or 17.5 will still work, it will just put slightly less load on the test motor.

Is their an advantage of a lower over a higher load?

A higher load will bring out deficiencies easier, and sometimes make the data easier to see where the divisions are. But take into mind that a higher load is harder on the motor analyzer you are using. Specifically the Tunalyzer will “stall out” with higher loads. That said I wouldn’t worry about that with a 25.5, just use another 25.5.

Thanks for the fast response
