Gonna cry for a week !

Mail Rob and Linda at DW I am sure they will help in this situation.

I go take a picture of the PH spare I have

japp got it and replied !

Just found a dealer that has it all, http://mikrokopter.altigator.com hope that true, wah gonna call before is better.

(Edit) Really worked like a charm, Ordered Tracking number 3 hours later, I like it !!!

Okay arms on and motors mounts and soldered back together. The motors seems okay with the first motor test with the mk tool.
How can i check more percisely if they are okay. Small vid if anybody sees something:

I really dont know to much about the scope info in the mk tool would one of you be willing to take a look at it if i make a video of it. What should be shown in the scope ?

Thanks

Boris

The most important thing to do after a crash is to check the accelerometer and gyro sensors. Deselect the other sensors from the scope to get rid of distractions and watch for proper gyro and ACC movement as you rock the craft. Also compare the gyro compass to the magnetic compass.

 

[BorisS]

okay thanks will do !

 

[BorisS]

gyro kompass and magnetic compass give the same data maybe of by 2 or 3 from time to time. ACC movement also seems to be okay. The only thing that is strange is that although standing on completely level ground the nick and roll angel show such high values -15 +20 etc. never had that before.

magnetic and gyro compass hard to see but they cover eachother

 

[Crash]

Calibrate the ACC with the props level. Calibrate the gyro with it sitting still and put the gyros on the screen also. They are usually the first thing to go bad in a crash.
The gyro line and ACC line should follow each other pretty closely.

 

[BorisS]

Okay calibrated and i think it looks better, ACC Nick ACC ROLL stayed as Zero and N angle and R angel -2 +2 something

Swinging once more after calibration:

seems okay or ?

 

[Crash]

That's exactly how it should look.

 

[BorisS]

Great thanks for guiding me through. Seems like I lucked out this time and except the frame nothing is seriuosly damaged.

Thanks !

Hmm little worried about the altitude sensor. Testing an fiddling around with the kopter hocked up to the lipo and i noticed that every 5 min 1 meter of height on the jeti box is added. Starts at 0 meters and I had it up to 9 meters in the mean time. Anybody ever experience that ?

Test flight tomorrow if the weather allows, but this i worrying me.

 

[ovdt]

Boris I experienced that too. When calibrating the gyros before the flight, the altitude resets to zero on JetiBox. But after a while, even I won't take off, it starts to increase. I didn't took it serious, I'm gonna check it after rebuilding my bird again.

Hi ovdt,

I Just flew mine for the first time after the crash. Kept in a 5 meter circle in the back yard not higher than 2 meters, due to strong winds and constant rain setting in. I couldn't test the the altitude hold. But the same thing happened again. After a full Lipo flight he landed with 9 meters on the Jeti . Yesterday standing on the table he even got a -11 meters at some point. Strange hope the weather gets better than I will test the altitude hold for a complete lipo and see if he descends over time.

Otherwise he is flying nicely. No problems at the moment. Pulling strongly to the left and a little forward, gotta calibrate him again.

 

[Droider]

It works on barometric pressure I believe so if the weather is changing so will your altitude!

 

[BorisS]

japp I also asked in the mikrokopter forum and some guys are experiencing the same, saying it not an issue. In the meantime a manage to get a full two lipo 13 min flight done all with alt hold on and i had no problems.
