The new Viper II 4041 Analyzer is absolutely brilliant! Improved menu functions, large color screen, quick start-up time and Transient Balance all combined to make Fan Balancing a happy experience. Best upgrade to date, please keep up the good work!

I would like to extend our thanks for the above and beyond assistance you guys provided for us in the time of need to get our test cell up and running in a timely manner. The level of support and service that was provided was without a doubt one of the best we have ever had.

Your team seemed to drop everything to help us with the questions that arose and were very accommodating to help us with the growing pains to understanding the system.  You also pulled out all of the stops to get us a rental unit to support our Viper when our unit went down and expedited it through your shop to have it back to us as quick as possible.

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).

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.

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

"...[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!"

"...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."

"...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 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."
