Testing X8 configuration without two propellers

Posted on March 17, 2014 at 5:04am 10 Comments

Yesterday I had a few tests with our Tiger Shark in Octa Quad configuration.

The tests were made to see how the copter would cope the loss of one or two propellers.

FPV on holiday

Posted on June 25, 2012 at 8:29am 6 Comments

My wife was nice enough to let me bring my quad and FPV gear on vacation :)

Had dozens flights using Multipilot32 with MPU6000 and latest ported Arducopter32 2.6 firmware.

Unfortunately the quad had some vibration problems and wind was always quite strong.

I think it's time to change motors and frame....

Had a lot of fun. This…
