Channels required for a Heli?
I have heard that an electric Heli needs 7 channels, but a 6 channel system can work by doubling up the power function with another function.
If this is true, then how does the Axe CP do it with a 5 channel system, while the E-Flight Blade CP uses 6?
Also, can someone please list what each channel is used for (not for a specific brand/model, but if the standard is 6 or 7 channels, what each does)?

Thanks!

Ch 1: Aileron (swash input) [swash side, 120/140 style)
Ch 2: Elevator (swash input) [swash front or back, 120/140 style)
Ch 3: Throttle
Ch 4: Tail (rudder)
Ch 5: Gyro gain
Ch 6: Pitch [swash side, 120/140 style)
Ch 7: Govener (or is it govenor)
Ch 8: Govener when using Ch 7 for Gyro tail lock gain (JR gyro)
Ch 9: Mixure
Ch 10: Rear tail elevator (scale)
Ch 11: Retracts
Ch 12: bling light

one way or another ch 1,2,6 go to the swash. 6 is not needed in a fixed pitch heli.

Ok, jokeing about 9 to 12, but they can be used

Please someone correct me if I left something out, or wrong.

Keep an eye in the classified section. I'd go with a 9 channel so you don't limit what you can do down the road.

First, thanks to those that have replied here so far!

The two models of electric Heli that I'm considering between, to purchase as my first one, are the Blade CP and the Axe CP.
Both some with their own transmitters, electrics, etc. Basically complete.

Between these two models, anyone know what two channel functions are not on the 5 channel Axe? Or what is possibly missing on the 6 channel Blade CP?

If I was already experienced enough for the T-Rex 450, I'd be looking at that and getting good electronics for it.
But being that I'm a beginner (so far), I don't want to invest a lot of money until I'm more experienced and still enjoying the hobby.

I do not know the Axe CP, so I cant tell you the chanel difference.

however, I do have an opinion, step down a bit, get the Blade CX, learn with it, then go got the T-Rex.

I never owned a CP, but have CX, and nitro heli's I know a few people that have gone from CX, CP, T-Rex, Nitro, and what I hear is the CP was too hard to fly at first, but the CX was not, and it was easy to go from CX to T-Rex.

The CP, as it described to me, is a full heli so it requires good flying ability. The CX lets you get some skill down before you step up.

Just my two cents

Also, you should realize that if you buy one of those heli's, your not going to be using the radio that comes with it, when and if, you upgrade to a trex nitro something or similar. So if you buy a Cx or blade whatever, learn to fly with it as it comes, and then move into a good quality computer radio and heli. I would suggest a 7ch as a minimum. (Would highly recommend an 8 or 9 ch.) JR and Futaba seem to be the preferred. Both are good, I fly JR and like it pretty well.-----------------------

I don't know about the Axe CP, but he Blade CP only uses 5 channels stock. 3 x swash, 1x tail motor, 1x throttle. The 6th channel is reserved for when you add a HH gyro and the 6th channel is the gryo gain.

IMO the T-rex is a much easier helicopter to fly than the blade CP. However the initial non-recurring cost of Transmitter, charger, and batteries is a deep investment for something that you are not sure about getting into.
