Last flight of the Seagull Mosquito. Previous videos showed the steps of a notoriously difficult aircraft to the point where we were confident in the setup.

And we finally did it, we found the perfect setup.
2 x SK3 4240 kv=740, 2 x 60A ESC and 13x8 aeronaut props (L/R), 2 x 5000 mAh 4S Graphene Panther Lipo's, separate LiFe for Rx.
This combined with some modifications (see my channel)...

And now the power was perfect, the center of gravity was perfect...
She flew beautifully.

But we forgot to tighten the nut of the left-turning prop hard enough. Due to the direction of rotation of this prop it came loose. After years of testing, consulting, rebuilding, repairing, we were ruined by such a stupid mistake.

So we lost an engine and a big spin and crash were inevitable....

Goodbye Mossie :-(
