The 2K10 Open Soar

in Carlisle, PA was a huge success!The altitude limited electric sailplane format is off and running in the US.Next stop is the NATs where a trial altitude limited event will be held on Sunday, August 1st.If youíd like to join the fun and havenít registered yet, you can register on-site.Donít have a limiter?No problem.Soaring Circuits will be there with loaner CAMs for those who want to try this new format without purchasing one yet.



Competition Altimeter for Models

Designed for the new 200m altitude limited electric soaring format, the CAM is small, light, and easy to install.  Just plug it in between your receiver and ESC.  That's it!  The CAM automatically shuts your motor down at 200 meters or after 30 seconds per the emerging altitude limited soaring rules.  This new competition format promises to put the "soaring" back into electric sailplane contests.  Even inexpensive RTF models can compete!

The CAM has selectable cutoff altitudes of 50m, 100m and 200m, and does not require a computer to program or use.  You can easily change the cutoff right at the field.  With the CAM you can make multiple climbs to cutoff without having to land.  Great for practicing!  And, the CAM is designed, built and supported right here in the USA.
