bungee launch X8 5.3kg

Posted by jim C. on January 6, 2013 at 10:30am

This is a mechanism in place to launch the X8, when its weight is 5.3 kg. his recovery is done by parachute. http://diydrones.com/profiles/blog/list?user=15tihx7n8mzza

the mechanism is very reliable for heavy winged lanzameinto. unfortunately my x8 fell into a bad spin maneuver and crashed, and I could not keep doing pruenbas with APM.

hi jim, very nice setup bungee launch. sorry for your lost/crash x8.

Can you post some photos of the hooking mechanism where you attached the bungee to the x8.

Very much appreciated. Thx for the post so far, very educational.

Very nice idea for the launch handles. Can you share your param file?

the triangle-shaped bars are fixed, the point of support for the bungge, the box is rectangular.

I had tried mine by bungee hook at CG but it resulted crash so i have just changed it on a rectangular box underneath X8. Is it the right place

Are these triangle rods remain fixed with the plane or its left in your hands after the launch

wow thats great,i am impressed a lot from your launching mechanism . I have broken many propellers in bungee launch of my X8, in my case i have fixed one side of bungee on ground and other side on X8, i pull the X8 from backside of wing as you are doing .But I have just noticed in video you are using some straps to pull the X8 . Can you please share what kind of straps and how you have installed these on X8. I am just getting 45 mins endurance with 10Ah 3S and all up weight of 4 kg. Are you using 4S and which motor you are using for this setup.
Thanks jim.
