Ok. If there is anything, I am available by email.

@Old Man: If your tool does not satisfy your needs, you can send us an email and we can figure something out.

@Av8Chuck Both tools are limited to 5kgf due to the load cell. We had to choose a thrust range, as a load cell with a higher rating will have a lower precision in the low range. I think 5kgf is a good balance between supporting larger motors and micro motors for most multirotor, but there is...

Sorry about that. Was it still useful for your tests? Is it because you did not see the specs on the website or on the datasheet, or because the thrust was higher than expected? Is there any way we could make the specs more clear? We also unlocked the thrust to 5kgf in the last update (load...

I posted here a few months ago about our tool professional motor test tool dynamometer and, at $495, it was a bit too expensive for most enthusiasts. Well, we worked on something simpler and here it is: we are now shipping the RCbenchmark Series 1520. It measures overall efficiency, current...

If the smaller size of the coax allows you to install larger props, you might not notice the loss in performance from the coax, as larger props compensate.

I think google map is a much easier way of getting an idea of what looks like a place... It sounds more like an idiot who wanted nice footage of an industrial area.

This is really unfortunate. If only there was a way the enthusiasts and the industry could self regulate. This idiot gives us all a bad name, and it makes it more likely that harsh regulations could be adopted.

I have been pretty busy working on a motor model last week. Here are some examples. The powers are in watts. The motor is an NTM 28-30 800KV. Also, here are the constants I obtained: KV: 800 (experimental) The most known motor constant. It came out to exactly 800 surprisingly. I tested a...

Sorry, I really though I was watching this thread... The max thrust is 3kGf. The max RPM is 200 000 rpm on 2 poles, 33 000 on 12 poles. The largest prop we tested is 16 in, but again, the limit is the thrust. PS: The max torque is 2Nm. We never reached that with props.

We are adjusting our launch price, and added a launch discount of $50, so our product is now $445. On top of that you can use the coupon MRF15 coupon until November 15. Customers who ordered in the last 48h will be refunded the difference.

That is pretty interesting!

Prop efficiency will not be accurate for airplane propellers, as they are designed for an incoming airflow. If you need that information, it is possible to use reference tables, or wind tunnel tests (from which the reference tables were generated). For example, this paper has experimental and...

Hi, You are right, the propeller test is a static test, similar to hovering for a quad, unless you are using a wind tunnel. In practice though, prop data are usually well known in moving air for standard profile. The biggest unknown is often the motor. In that case, the propeller is only used...

Hi guys, I am a recent graduate of M.Sc. Mechanical Engineering from Ottawa, Canada. My colleague and I designed a dynamometer and motor tester specifically from UAVs and quad designers. We actually started this project after spending weeks to build our custom solution. "" For the release...

Thank! I completely understand your point of view. We thought a lot about this, and we decided to start with a very high quality tool, with the features and precision required by researchers, businesses, and serious hobbyists. The software is constantly improving, and we want to make sure to get...

Hi I'm Charles, from Ottawa, Canada. I started flying with helicopters (450 size), and went into acrobatic flying with mini-helicopters (mCPx bl). I then started multicopter flying. Heli was fun, but way too much time to repair. I also recently graduated from a M.Sc. Mech Eng, and I started a...
