Maiden Flight, HSD F-16 Turbine V2 with Kingtech K85 G4 Crash at Takeoff, Nose Gear fail 

For anyone considering or has an HSDJet. As Adam mentioned, there is a servo that operates the front landing gear support strut. You will hear it "click" when you cycle your gear. It's important that, when the control unit or receiver is turned off, that you first cycle your great for that support strut to lock in place. Or, that will happen. It's easy to understand if you put the plane on a stand and operate the gear. You will actually see the servo that controls the strut/brace.

In the website says "Not suitable for grass runways". It seems it is true.

I've had 3 of these (electric) and they are definitely not suitable for grass runways unless the grass is manicured like a golf green.

The site literally says, "not grass takeoff capable "....

big mistake trying to fly off of grass

hello so 2000 CHF ok for you ??? thank adam !

you know you're master error not try take off on grass this model can take without problem you haven' initialized the retrct gear !!!! so you're 360 nose servo wasn't locked .....
