Id now vather get in to RC helicopters than RC airplanes. Because where I live its very hard to find a spot to fly planes. I was gona ask. You need atleast a 5 channel radio for helicopters like the Century Hawk Sport right. I was kinda confused because I know on real helicopters the throttle and the colelctive ptich are different but on RC helicopters they are mixed in right? But then how do they perform inverted hovering? I was a lil lost there.

1 servo for throttle
1 for aileron
1 for rudder
1 for elevator.... what else...

I really liked the century hawk sport because its so cheap I figure why not.. Any thoughts, please

1 throttle.
1 left/right cyclic
1 for/aft cyclic
1 pitch
1 tail rotor

Add another one if you want variable gain on the gyro and another for adjustable gain on a governor.

jtatarin: inverted hover will use another of the buttons on your radio, (Idle Up), and some mixing called "Pitch Curve".

Basically:

The idle up button allows you to set a constant rpm, regardless of the position of the left stick.

The pitch curve allows you to set sufficient positive and negative collective pitch, (you'll usually see a range of -10 to +10), based on the position of the left stick.

For an inverted hover: engage the idle up, (so the rpm won't be affected by the left stick), flip your bird over and pull back on the left stick 'til you get about 6 degrees of "negative" pitch.

Although you pulled the stick to a "negative" position, the bird's upside down so it actually has positive pitch - and about 6 degrees should let you hover.

If only it was as simple as it sounds!

So far I've only tried it on a sim: I can keep it inverted and off the ground, but I haven't been able to even approximate a hover that way yet!!

Also, what exactly is the afk cyclic, is that the pitch and and down cyclic (elevator). Also, Is the RD6000 Super a good radio?

aft = back

The Cyclic controls your pitch and roll, (elevators and ailerons) - the attitude of your rotor disk.

Aft Cyclic, (up elevator), tilts the rotor disk aft.

It might help to think of it this way:

The right stick of your controller is the cyclic, this is two servos working together (in a normal heli, not CCPM), that move your rotor head and allow you to move the heli left/right and back/forward.

On the left stick, the forward/back direction controls two different things: Blade pitch (how much the blades "bite" the air to generate lift) and throttle (generates energy to move blades). The more the blades "bite" the air the more power that is required to spin them at the same speed. That is why your throttle and pitch move up combined with each other.

the right/left movement controls the tail rotor. You change the pitch of this to induce movement of the nose of the heli (think steering wheel on a car).

This is such a simplified model that it almost has nothing to do with how heli's actually fly. You can't just input one control at a time, three is about normal just for hovering.

For example:

To take off, you'll spool up throttle/collective (push left stick up), as the tail rotor blades generate sideways thrust there will be a tendency for the helicopter to move in the opposite direction of the thrust being applied. A tail rotor on the right side of the boom will make the heli want to go left. So add in a little right cyclic and right tail rotor. Those are the controls that must be used just to get the heli off the ground in one place.

Hope this helps.
