This is the HobbyKing OrangeRx V2 Stabilization unit on my Pusher Delta. This delta wing is a great park flyer but definitely gets pushed around by the wind. This stabilization unit works great for windy conditions!

Please see my other videos for information about setting up this stabilizer on a delta wing and for information about this wing and how to build it.
