“The Cobra II is a great system! I used it only 2 days after receiving it the first week of September ’21 and was able to successfully complete a dynamic balance in one shot. Needing just the initial reading run and the adjustment run. Fantastic, smart system. I’ve used two times since with superb results….
“I feel you get much more than you would for equipment that is more expensive.”
“…using another system, it took over 20 cycles and two days to track and balance our MD500D. Since purchasing the Model 2020 (ProBalancer), we have properly balanced our MD500D in 5 cycles, and it took less than one day.”
“…the Aces is the best portable unit I have used. It requires no additional battery or ship’s power and no blade targets. If you have ever been halfway through a tracking flight (particularly with a Bell 412) and had a target come off, you will know how frustrating this is…and expensive.”
“…I have found the ACES Systems Model 2020 ProBalancer to be a very reliable piece of equipment. It has an easy installation, it’s easy to use and understand, not to mention that it’s been a real time-saver. It is not uncommon to have the Robinson R22 and R44 helicopters balanced to .02 IPS. That’s quite…
“…[balancing of the Bell Jet Ranger 206B3] was accomplished with one-third of the test flights that other systems required…”
“Just prior to coming here, I was breaking in a new motor and started experiencing high vibrations at the higher RPMs. We spent a little time balancing the prop using the ProBalancer Sport and the difference was significant. I’m very, very happy with the results and recommend the system.”
An unanticipated bonus of this equipment…paid for itself with this usage alone (AStar, Citation SII, and Challenger 601).
It greatly reduced the vibration levels throughout the complete rotor(s)/rotor(s) drive system on one particular aircraft in our fleet (UH12E/Soloy) which we had not previously had much success on.
The equipment is so easy to use that we figured out how to use the equipment and successfully did the necessary job (TFE731 vibration survey).
