CP3 Spins like a plate which has lost its speed.

[joaliff]

I have a Esky Honeybee CP3 helicopter it has cost me a fortune on spares so far without a flight so I have invested in some small and medium four channel helis to train my fingers as to how a four or six channel machine flies and I can belt these around a flying field no problem without any fatalities i should have done this first.
But I have a problem with my CP3 as I cannot get it to hover flat and stay there it will take of and start to hover but it then starts to gyrate very slowly like a spinning plate that's lost its speed but over a larger area.
I have put a CNC full metal head on it and everything looks ok but its so frustrating.
Has anyone had this happen to them.

do you mean the heli is wobbling bobbing in a hover >?

Hi Gaza,
Thanks for your reply.
It is difficult to explain, if you tied a bit of string to the top disc above the flybars without running the helicopter and imagine being suspended six foot above on a invisible platform, and you lifted the helicoper with the string of the ground 18" and the swung the helicopter round in a 4 foot circle with the helicopter always facing north, the helicopter would look like its changing its axis as its goes around the 4 foot dia if you looked at the circle say at west the helicopter would be banking right at north slightly tail down east banking left and south the nose slightly down.
This is the only way i can explain whats happening.

hi cliff it sounds like you need to check the cog of the model (centre of gravity)hold the heli by the flybars and see which way the heli sits ,then move battery a bit or add weight to make it sit flat and check the trim as the one under the throttle is the tail trimm .this should stop the tail driffing .hope this helps

[Gaza-Davies]

yes i would do what robbo sudgested sounds like a cg problem indeed check that first and get back to us

As I am new to Helicopters can anyone explain what function do the fly bars have, and if they were a fraction out or very slightly tight, could this affect the stability.

If the fly bar is bent will effect the handling. I found the Honeybee very difficult to get a perfect setup on. Check the cog, check the blades are balanced, flybar is straight and also the rotor shaft is straight. When it's perfect it's fun to fly, until I crash it and then one of the above needs sorted all over again.

Forgot to mention the blades on the flybar need to be the same angle, and with the right adjustment can make flying a lot easier.

[Gaza-Davies]

or sell up and buy a blade heli they are worth the money for beginner , but no you cant have any binding problem in the system or it will cause all kinds of problems

Got my Honey bee out today for the first time in months, been flying my micros. What a pig compared to the Blade MCPX and 120sr. Although it is good for practice as I'm having to make corrections constantly.
