LOGO700...please help

[LOGO800]

I built my Logo 700 end of last year. I did 2-3 flights in winter and I have not flown it for a while. Until today I decided to charge batteries and go flying. Today here in NORWAY: sun shine and warm and dry weather(about 23 degrees). When I was flying I noticed very strange behaving from my LOGO700. Jumping up and down, kicking with tail….exactly same behaving when it is static problems. I did not want to crash the heli and I landed safe.
I have been flying logo 6003D for over 2 years. Very happy with logo600. I had static problems with it .behaving just the same way that my LOGO700 XTREME did today.I solved the problem with wire the boom. Am I missing something here? Is it necessary to wire up logo700 same as 600 to not get static problems? Or what happened today? I haven’t had this problem before with my logo700!!!!!!
My setup:logo700 xtreme with stock motor,pinion,blades and vbar.
KOSMIK 160 esc
HV bl. FUTABA servos all over
2x6S 5000 mah batteries
s-bus FUTABA receiver
please help

I have not read about anyone having static issues with the L700. The tail boom should not be an issue anyway because its a torque tube.

If it was static theirs likely evidence of it in your Vbar log file so posting the log would help.

…..Happy ending. I looked at the vbar log. EXTREME VIBRATION…..I knew that I built this heli exactly the way it should be….then I review the vbar setup…I found that my blades are out of track. Not much. only 2 turns on link rod(only one blade)… solved the problem. I am not familiar to vbar and I did not know that vbar is so sensitive that it behaves like making heli jump up and down because of blades that are not in track!!!! But very nice..i am impressed and I learn new things every day even after being in this hobby over 6 years. Anyway…thank you for remind me to see the log. This heli flies really nice.

Good deal! Two turns out is allot on a large machine like this. I ended up getting a set of turnbuckles to replace the swash links, makes fine tuning the tracking easier.

Sounds good, which turnbuckles are you using?

[McCollister911]

any 3mm threaded ones in the 42-46mm (1 7/8")range for length The Lunsford ones are beefy
