I have been flying a hummingbird form hong kong for about 5 weeks now and although i have found out that the helicopter is actually very unstable from its conversions i have taught my self with the extended training skids to hover nicely within a metre square. I need some comfirmation i have been flying RC planes for a bout 2 years and have some nice models, but helicopter bring a whole new aspect to RC flying you dont need to go to a special area and fly on a special feild you can use the heli in your back yard and practice its wicked. well to my question if i was to change my HB for a nicer heli like a zom CP or a small size electric size CP helicopter do i need a computer controlled radio to use the CP aspect of the helicopter, at the moment i have a computer radio but i'm in engaklnd and its an amercan 75Mhz radio so i'm using my old 5ch futaba challanger radio it has idle on thrtle hold and the 4ch's for control, could i use this with a CP heli.
sorry for so much writting

well you could theorically fly a CP helicopter with a 5ch radio (and two servos slaved to one same stick)

Now, modern radios give the opportunity to set up your throttle and pitch curves.
This, for a stick position, you decide on throttle and pitch servo travel

On an helectric heli, the throttle is giving way to the controller. Most modern controllers have a built in governor function; this is, whatever pitch, the headspeed will remain constant and drawn current only will vary (you will draw more current at high pitches, at a given Headspeed)

So, on an electricheli, you will have a flat throttle curve.
You still have to set up your pitch curve, so you have homogeneous collective response.


Hope this helps

PS:by the way, where are you from Lojik?

And you can fill in your member profile under "my home" menu and also check other's in bound (that's in the left margin of posts)

Did you understand something about CP management with throttle and pitch curves?Radio and chanels issues...

Don't hesitate if you need help.

Many dudes and I will be more than happy to help you with your rc heli related questions

You may also have a look at the dedicated thread concerning hummingbirds

Take care.
