Default Esky Honeybee CP3 Jitters on take off

Hi All,

New here and after some advice, I am returning to flying RC Heli's after some years and have an issue I am unable to solve with my E-Sky Honeybee CP3. I bought this heli many years ago and had some success in learning to fly it and lots of success in crashing and learning to rebuild it!

After the last crash I boxed it up and put it in the loft after running low on funds to keep replacing parts for it.

Jump to now and I have retrieved the honeybee from the loft and attempting to take it to the skies once again.

I have it spinning up and all seems well and balanced, until the skids leave the ground and then it all goes pear! The helecopter seems to jitter and shudder, but only when off the ground. while sat on the deck it all seems balanced and stable.

Any ideas on what could be causing this?

It appeared to me that most of the twitch was in the tail, correct? I have a Honey Bee CP2 and adjusting the gain there is a fine line between the tail drifting around and shaking. You could try backing off the gyro gain a bit. Also make sure your gyro isn't loose. Even with the the tail would wag on my CP2 it was still flyable, and I just flew it like that until I was ready to advance. Does the heli correctly respond to inputs while in the air?

Hi winger76,

Thanks for the reply. I read on another forum the other day that the Tail Motors have a limited lifespan to them (around 10 hours) and after this they do not respond to the speed adjustments of the mix controller as precisely. I am not sure how correct that is, but in changing the tail rotor I also noticed that I think there may be a problem with the cable to the tail motor so I will need to address this also.
Mine being the CP3 apparently E-Sky removed the ability to adjust the gain on the mixer by removing the dial, so not sure if this is possible with mine. I will fix the cable and see if the motor change has made any difference and post my results.

The problem I had was that the heli wobbled so much that I couldn't get it in the air, it would take off, wobble so much that it would unbalance itself and then drop to the ground again.

I am thinking of getting a different Heli in the not to distant future anyway, I wasn't overly keen on the direct drive style tail rotor control and think variable pitch tail control may feel better.
