The Compass EXO is alive and well

When Compass Model gave a hint of the release of the EXO 500 I wrote a small news article for it at that time. Now they have hit the market and are starting out with a bang! I have the updated version of this story and I'm glad the time has come. Many months have past since that article and they have been getting feedback from professional pilots fine tuning the system. This caused delays, but the time has finally come. The main feature of this heli is the capability to hold higher head speeds without an issue, but the manufacture has limited the head speed recommendation to 2700RPM, and +/- 13 pitch. The EXO has a 10mm main shaft and a 6mm tail output shaft which is unique and a single stage 22m main drive belt to deliver power on demand. I personally hope to get my hands on this bird sometime in the future.
