"...[balancing of the Bell Jet Ranger 206B3] was accomplished with one-third of the test flights that other systems required..."

"...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 impressive!"

"...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 equipment is so easy to use that we figured out how to use the equipment and successfully did the necessary job (TFE731 vibration survey).

An unanticipated bonus of this equipment...paid for itself with this usage alone (AStar, Citation SII, and Challenger 601).

"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. And ability to make the reports and put them on the usb flash for easy printing or distribution, excellent. Now I just need some extra time to read and figure out the rest of the bells and whistles a little more. Thanks to all @ ACES for the great system and as always awesome support."
