DEVO RX601 Install

I have a Devo RX601 and want to install it in my DH9100 with Xtreme 180 Pro motor so I can use my Devo 7 or 7E TX with it.
I do have the plugs for conversion

A few questions:

1. Would this require an ESC?
2. How would batterY power hook up with it(which slot)?
3. What would be the max size battery I could use for it?
3. Could anyone provide a wiring diagram for for this conversion?

1. In any case. I don't know it he 180 Pro motor is brushed (I assume) or brushless but in both cases the rx can not deliver enough power and will burn - besides that the signal coming from the rx (since it is no specialized for a specific Walkera heli model) is a standard servo PWM signal which you can't use to drive a motor. There are many other receivers from Walkera where the motor controller for brushless motors is built in - maybe you should get such a receiver, would make things easier.
2. Since you have to use a motor controller you will probably get one whit a builtin BEC - if you connect it to the throttle slot the receiver will be powered this way. If not, you would have to use a free connector or split a cable.
3. With a motor controller with BEC or an external BEC the manual can tell you what battery (which voltage) you can use with it. Since the voltage is regulated for the receiver (by the BEC) the battery voltage does not matter for the rx. The current is also not interesting - it should be enough to give you a sufficient flight time without wasting too much weight to make the heli slow and cumbersome.
4. Sorry, not me.

In this case an extra motor controller for the tail is needed.
It sound really easier to me to take a receiver from e.g. CB180 which has a brushed main and tail motor and the motor controller included.

True, but the Devo RX601 is sitting right here in front me free of charge and I have Devo 7 and 7E TX's. If all I have to do is get a cheap ESC to make this work with my remotes, wouldn't it be worth it since cost would be very low?
