Scherrer UHF Review & Torture Test

First off thank you for your efforts. I can certainly appreciate the time put in to your reviews. You guys have become quite popular and have a large following. I am no engineer and no expert in RC so I follow people such as yourself for reviews on what I purchase and how I go about setting up my aircraft. When people such as yourselves transcend the average 25 view joe blow reviewer on the tube I think you take on the responsibility of removing as much bias as possible when presenting your tests. No doubt this review after watching it from my experience level would steer me away from purchasing a TSLRS. I don't know if that was your intention or not. In the next few months before you put out another video regarding another system there will be nothing to compare this video to and the predominant feeling I walked away from your video was not positive towards TSLRS. I disagree with your method of testing without antennas full stop. I am not real happy with the use of attenuators and then using maths to determine approximate results in the air. I would have been much happier to see a setup tied to a balloon, on top of a building, or top of a mountain and tethered to the ground at altitude whilst you drove to various measurable distances and reported your results with the gear wired and hooked up as designed. The voltage drop test which was the most concerning of the tests to me. Alex states that the TSLRS never recovers from a drop of volts to around 2.x volts even when the voltage in re increased. In the same breath he the states that he would rather stick with his old system even though it drops off at 4.volts because if the volts recover the rx comes back to life no worries. Alex states that because of this test he would not use this system as it is too dangerous as it is. One could equally and fairly state that if your supply volatge dipped to 3.x volts and remained there then Alex's current setup would not be able to function and he would have a brown pants moment where the unit using the TSLRS would still be flyable, Ok I pinched this next bit from the RCgroups but it hold a great deal of merit. Can you say you followed these rules for scientific testing?
1. Name and model/rev of all equipment used. TSLRS, CPPM source radio, VTx, VRx
2. Purpose? Yeah, what is the purpose of the experiment? What is your hypothesis or what are you trying to prove or disprove.
3. Set up of equipment (connections, temperature, pressure, voltage, current, RF output power, input current/voltage to Rx/VTx) Also, how do you know all the equipment is operating to manufacturers specs? Are there records to reference standards? Data?
4. How were the tests performed, exactly. For instance, instead of randomly waving an RF output around a VRx, measure the distance and antenna angle, be precise. Yeah I know it is a Circular VRx antenna but so what, measure. Try different antennas. Try different VRx.
5. If you are going for a valid test, then perform to manufacturers specified parameters. Document that result. At that point, you can quantitatively "torture" the device to see where the limits of stability and recovery lie.
6. Findings
7. Conclusions based on facts and data.
8. Possible further experiments based on findings.

I appreciate the effort you guys put into your videos however I am concerned at the lack of methodology. Honesty in reviews is a good thing for the consumer. I applaud anyone who points out issues when testing products. However when you simulate real life conditions with attenuators, jammers, and removing antennas you risk inducing situations that would just not happen in real life or happen at all and you start to appear as if you were looking for problems and making them fore front in your review. Keep up the good work. I'd like to see the same test done to EZUHF and Dragonlink for comparison. You certainly gave the TSLRS a bashing. Here is TSLRS response.

Great video. Lots of good info from well educated people. Thank you for doing all of that work. No LRS system for me yet but some day.
