King2 - Can't get blades tracking

[anjdreas]

I've followed several tutorials and videos on this forum and other forums, but I just can't get the blades tracking. It's not just slightly off, it's a 3-4 cm gap at the worst.

I've tried:

• Make sure all trims and pots are at mid/zero positions
• Ensure swashplate is fairly level
• Hold flybar level, then use pitch gauge to adjust blades to -2 degrees in idle mode and throttle stick at mid position
• Keep one blade unadjusted at -2 degrees, then try to adjust the other blade to track with the first one. It always overshoots with 2-4cm either above or below the other blade. I only do 180 degree turns between each try.
• Try to adjust the first blade to "chase" the second blade in the hopes of them matching up better at a different position. No improvement.
• Replaced carbon blades with stock wooden blades
• Replaced the small horizontal blade mount shaft

E-Sky Honeybee King 2 - Can't track blades (1 min 10 sec)

when doing about 50-70% throttle. It gets slightly worse with more throttle. It has a nice track until about 30-40% throttle, and when increasing throttle slowly it suddenly just jumps from a few millimeters off track to 2-4 cm off track. There are little vibrations before the "jump". Close up image of assembly here.

I picked up the King2 after a few years of it lying in the closet so I really don't recall what started this, but it was either a minor crash or replacing blades, tail blades and boom with carbon fiber parts.

I've been at this for 3 days straight now with no improvement. Hope someone can point out something I've missed.

Cheers!

based on the video, I think you might need to check the spindle shaft.

Thanks for taking the time to look at this, but I wound up selling the model to someone who knew this stuff better and had use for it. Forgot to close this thread at the time, sorry.
