My first post, I have flown glow and gas for about 5 years, and have no experiance with electric flight.
I just won a Great Planes FlatOut Matt ChapmanCap 580 and have access to a Castle Creations Phoenix 25 controller and Castle Creations CM2042 brushless motor. Would this be a good combo?
What size/brand battery would work with this motor and controller? I know I need a micro receiver (Futaba R124F?) and servos (Futaba S-3109?) I thought it would be good to have so I could fly in our parking lot at work, I work 3pm to 11pm and it is empty except for about 20 cars the lot is about 3 acres so plenty of room.
Any info would be appreciated.

Bob, I believe the motor that you mentioned is a 4200 kv motor (4200 rpm/volt) which means that it would normally be used with a gear box. I wouldn't know which one. I think you would be better off with an outrunner which would turn an APC 9x6 SF or a 10x4.7 SF around 7000 rpm. One example would be an MP Jet 28/7-30D red outrunner. Many more would fill this requirement. A 3s 11.1 volt 900 - 1320 mah Lipo would be a good choice. The Phoenix 25 ESC would work fine. I highly recommend the FMA M5v2 dual conversion receiver.

I've been flying big gassers since 1982 and usually keep 5 ready to go at all times.

This is the info from their web page,,,,,,,,,

FOR AIRPLANES: Replaces sp280/300/350 geared brushed motors for more power, longer life and higher efficiency. Must be used with a brushless airplane ESC only. Our Phoenix 10 or 25 is recomended.

RECOMMENDED MOTOR SETUP
CM-2042 with 6.6:1 ratio Cobri gearbox and 3s lipo:
10x4.7 APC
9.5A
11x3.8 APC10.2A12x3.8 APC11.5A
I hate sounding dumb but I have never tried the electrics.

My Great Planes Flatout Cap 580 comes with the following motor and gearbox,,, I thought since I had the brushless motor and control I could upgrade.

Motor: T-370 size brushed
Gearbox: 5:1 gear ratio, ball bearing supported
Propeller: 10X3.8 slow flyer with prop saver

Here's some of the stuff I'd look at to complete your setup:

Gearbox: http://www.e-flightline.com/ This link is for the cobri gearboxes. Great gearboxes and strong. You could mount your motor in the gearbox that comes with the plane.

Radio: I assume that you have a futaba radio so you can use the micro gear from them or use Hitec gear ( Electron 6 and HS-55 servos)

Battery: I'd go with a 700-1320 mah battery. I'd go lipo but you will have to buy a charger for it. IMHO, I'd stick with the major brands like Thunder Power (my first choice) or Kokams. There are others out there and I'm sure that they'll work for you.

Feel free to ask more questions.

good setup...6.6:1 of 5:1 anywhere around that is fine. get a battery that can supply 13A or so continuous. 3s 1000-1300 would be perfect.

anything from 10C up is fine also..no need to blow your dough on something 15-20C though...it can save you weight at the expense of flight time...swings and roundabouts- except for the price.
