Upgrading E-Sky To 2.4GHz

[scallybert]

How feasible is it likely to be to convert an E-Sky HoneyBee CP2 to 2.4GHz ? (HBCP2 is collective pitch, CCPM, tail rotor driven by its own motor, uses an E-Sky 4-in-1 {receiver, etc, combined}).

I'd be thinking something like a Spektrum DX6i and AR6100.

I'm pretty new to this, but the problem then seems to be that I have to replace the other functions that the E-Sky 4-in-1 performs. ie ESC, rate gyro, mixing for tail rotor speed.

Can you buy suitable 3-in-1s ?

[The Blade CX2 (co-ax) has a 3-in-1 to work with an AR6100. But (aside from not seeing one listed anywhere), I'm guessing this won't handle the bigger main motor and 3S LiPo, assuming it could suitably control a tail rotor motor anyway.]

If you done it then you'd have to purchase a suitable seperate gyro/ESC also. CX 2 is totally diffrent heli and doesnt manage a tail rotor. You therefore dont need a mixer as the gyro will manage the tail rotor. Obviously you need something to manage the motor so will need an ESC also. The 3 in 1s you've seen are probably the new units for the new cx2 which has a seperate ar6100 rx. There no good for the cp2 as explained above.

I guess it figures that you can get these separately.

An ESC just plugs into a channel on the Rx and drives a motor ?

Whatever drives the tail rotor motor will need to combine a proportion of the main rotor speed with the (rate) gyro output and the Tx yaw input, and also ESC the tail rotor motor. Does a single gyro unit combine these ?

One thing that would be helpful, so I can read up on them, is any manufacturer and part # for such an ESC or gyro. It doesn't need to be particularly suitable for an HBCP2, I just want to look and see what's around.

ESC just plugs into the throttle channel on your RX. I seemed to have got the HBCP2 mixed up with another model so yes you will need a mixer for it then. The 3in1 unit will do the job fine then. No a gyro wouldnt combine the 2.

you would be better off getting 1 of these and putting the 2.4ghz + 4x hs-65mg servos in it.

just look at that price - thats the cheapest anywhere

Aye, problem is the 40 quid P&P

Yes. There are a number of things wrong with what I'm thinking if doing. A Blade 400 3D might be a more sensible option too.

However, there are reasons why I'd like to do something with this HBCP2.

Hence I'm wondering what's involved.

I know I don't know much, but there must be suitable 3 in 1's for the AR6100, as that's what the Blade 400 uses and that's a CP 3D heli isn't it?

There's a significant difference between a B4003D and a HBCP2.

The B4003D tail rotor is belt-driven from the main rotor, and the tail control is by changing the pitch on the tail rotor. A servo does this.

On the HBCP2 the tail rotor has its own motor. Hence there's a tail motor to control, and the speed of this is related to the main rotor speed (as well as stick input and rate gyro input).

So I doubt the kit from a B4003D will work.

Thanks Scallybert, have to ask or don't know these things. A lot of this you can't possibly learn from Coax helis, and don't want to ever think about moving on till I do know a lot more.
