Hello,

bad story... sad to hear :cry:

following the log head&tail went into limits immediately and RC signal was lost at the same time. could you show some photos of the components & Spirit mounting plus Spirit cabling details? all cables where still connected after the crash? which Rx was used (and configured how)? do you have some logs of your Tx or did the Tx notice a lost signal?

... and if you power the heli now (without blades) on bench with Spirit connected to pc... what does diagnostics tab show for all the channels? and - if possible - what does it show with motor started? (just the same as before when crash happened)

After the crash, I connected the helicopter to the battery again to test the direction of the tail.

Do I have wrong log files?

where do I get the older files?

if perhaps have not installed a tail rotor blade correctly ?

Hi,

i would say the log is not the log of the crash (only 30" is too short and went directly into limits)... but if it is of the startup of your Spirit unit after the crash, it seems your Rx=>Spirit connection is not working properly (getting wrong channel data?): that's why i suggested to reconnect everything to Spirit Setting software (blades off) on your pc and check. if it is ok, (take all blades off) check with motor start... this is where your heli went crazy if i understood correctly?

Hi,

One Pic only Started and One pic all servo moves

I think I hit the stairs while carrying it or something like that.

I had stupidly not made a pre-flight check.

sometimes i'm hectic.

Is this not just a case of the heli being moved after it's powered on? The 'rudder limits reached' smacks of the heli being swung around before flight?? Then spooling up with blades hardover....?

i don understand erverythink, im from Germany

But yes i have moved the Heli a little bit because the underground was too rough for me (1m )

Spirit dont like it after Powering moves ? That the Mistake ?

I've always done it with Vstabi and never had any problems

Try and power on the Heli in the position it's going to take off from. Also worth making sure the tail blades are near neutral before spool up.
Rough ground isn't the best either! Good luck
