Before a long time and many practice I learn to hand launch my Sw 168 but I'm not confort because I'm a small woman and it's an efford for me to launch my hevy sw with FPV, camera APM etc.so I saw Brett catapult and decided to build one
THANK'S BRETT FOR THE IDEA AND BUIDING DETAILS!!! :) :) . MARTINLERE FOR HELP ME, AND THANK'S FOR THIS DISCUSSION GROUP!!!
Now I'm finishing it, only some little details to finish and try but I want to share with you my advances; I'm in winter now and bad weather to fly but good to build. ;)
