2.6” version of the Competitor series, already have the 4” and 5” built and flown and now this one. 2.6” in diameter with a 54mm motor mount. 

actually built this to keep on standby, super easy to prep and versatile, if I lose a loc on my gps tracking on another bird this one is set up to go up quickly and attempt to reacquire the signal with the lost feature featherweight trackers use.
