Hello , I bought 2 EDF 64 mm to fly my F22 Raptor...
Actually , I want to know what is the best ESC that fits for this kind of motors.
i.e 30Amp ESC is fine , or 45Amp ESC or what ...I know that I have to use 2 ESC.

Another question about the battery , I know that this motor works with 11.1 V .
and I bought a battery of 5000 mAh 7.4 V ( I didnt know why I bought it )
can this battery run those motors together with the ESC ( and I will another microcontroller circuit ) .
Any info will help ...thank you all ...

you want to go at least a 40 amp esc for each motor..the 64mm EDF's usually will pull close to that on most planes. Your 7.4 pack will not work with these very well..plus it is very heavy and big for most planes...the 64mm EDF's really need a 3s pack to work..and most twin EDF's will even ask for a 4S pack depending on the motor and setup...

You have to use 40-45Ams ESC x 2 , and battery 2200 mAh on 3s for these motors if they are 11.1 volts

What are the kv's on the motors? I have 3500kv 64mm that need 4s. With any edfs of a decent wattage I would also recommend 40c batteries and also programmable esc so that you can set timing to high if necessary. The best bet while experimenting with edfs is to buy a combo so that EDF performance is out of the equation for setting the plane up. I bought 2 70mm EDF combos from HK for my Shumate su37 twin EDF and could concentrate completely on making the plane fly rather than on getting proper power. That's my 2 cents....

Here is my setup.
dual 64\'s.JPG 

Your ESC should be at least 40-45 amp and use at least a 40-45 C on your battery. I use 2 1300 mah batteries and get about 4+ min of flight. Your 7.4 pack won't work.
I have found out that 1 70 EDF on 4 s will give you a thrill in flying it.

I first flew this setup(World's first) without any surface controls (3D TV) and it was super fast including the landing. Since there was no deflection of surface controls, most of the drag was eliminated.
I then added controls and it is still a handful at full throttle. Please remember that the landing speed is a lot higher due to the increase weight.
I like to design and fly unique planes.

Sorry guys for being late...
first,I just wanted to know , what is a battery of 2S or 3S is it number of cells ? ... and what is 40-45 C ?
second, now I have 2 64mm EDF motors, so I have to buy 2 X ESC each of 40-45 Amp , and to buy a battery of 2200mAh (3 cells = 11.1 V ) ...
dont forget that I need some other power to run other circuits that I need on the plane ( not much )
and how many minutes will this battery fly that plane ?

Please don't take this the wrong way, but have you flown these planes before? The cell count (2s,3s,4s)anf esc amperage is the basic info needed to build a plane. Using edfs can be difficult for even experienced pilots to fly. Have you flown prop planes? My concern is that, like many beginners who fly EDF planes first, they become discouraged because the plane will not get into the air.
But, many 64 mm need 4s power, and definitely need over 40 amp escs, one for each unit. The cell rating for the battery is also critical. 40 c or higher. This will give maximum power without overheating. What motor specs are on the EDF?

thank u guys , since I am a beginner , I think I have to start with F22 Raptor design , with a propeller motor and use the recommended motor and esc etc ...

Good choice! Don't forget to get a good simulator and practice on that first. I'd recommend ClearView RC Sim (rcflightsim.com) as it is a great sim for the money. You'll also need a USB Simulator controller (http://www.hobbypartz.com/60p-dyu-1002.html) so you can "fly" the plane on the simulator. Good luck and happy flying!

Thank you bro , for that , but they told me that the EDF is Hard to control , why is that ? I have a simulator bro thank you...

Another question , if I have 2 motors EDF , each of max current 30 Amp , can I use one ESC about 70-75 ESC , or I have to get 2 ESC .... ?

Another question, I want to control the motor through a microcontroller,
i.e connect the motor to ESC , and connect the ESC to a micrcontroller , then send PWM from the microcontroller to the ESC , will that work fine , with no problems..
thank you all guys , I am just a beginner in RC Airplanes

Sorry, I read your post wrong and assumed that you meant the RCPowers F-22 V2, not some other EDF F-22. EDFs are hard to control because of their high speeds, slow acceleration, underpowered, and high wing loading. I wouldn't recommend an EDF for a first plane because of those reasons. If I were you, I'd either build the RCPowers F-22 v2 or F-35 v2 first, become a proficient flyer, and then learn to fly and EDF.

AccidentalStuntPilot gives great advice.
EDFs are hard to control because of their high speeds, slow acceleration, underpowered feel, and high wing loading.
And I also wouldn't recommend an EDF for a first plane.

You can use one ESC, but I rarely hear of someone doing so. There are some advantages to using two BECs. Twin motor yaw control?

Why!!
Starting simple:
All of the experienced pilots I know encourage beginners to start with Tailerons or Elevons only, on a "proven good" single prop design, built the way the plans show. In one of his post, Dave said "Start simple, master SOMETHING and then use that to leverage your way up to the next step works so well. One step at time." All beginner pilots want to start with the biggest baddest and the best, it's human nature. "Starting simple" is a foreign concept to us. Many beginner pilots build there second plane simple because their super plane failed or flew like a brick. "Starting simple" means choosing a set up where only 100 things can go wrong instead of 500; this will take a lot of bumps out of the early learning curve. The Taileron's 2 servo configuration is not only the easiest to set up, it's also the cheapest. This is why we encourage beginners to start with Tailerons only.
