Default motor suggestion for greatplanes Cap 580 flatout

I've been putting this together to start exploring 3D flight and I'm looking for brushless motor options that may be cheaper than the suggested rimfire 22m-1000 GPMG4500?

It came with the brushed motor but I have to buy a brushed esc. I figure I might as well go brushless from the start but the options are confusing.

The plane has 36" wingspan and weighs 9 oz.

Any help appreciated

Well most would use 150-200watts/lb

150/16= 9.4w/oz, or about 84w for a 9oz plane

HK has many options for small foamies. Something like a hextronic 24g 1300kv BL Outrunner or the like.


Aloha,
Les

Hi Steve those Flat out planes are very flimsy and weak IMHO, a brushless motor will rip the wings off of it, I know i had one, it was my first rc plane, I did not like it at all, but it a ok starting point i guess, just use the stock motor assy. and later get a plane that will handle a brushless motor, brush esc are cheap enough,

Brush 10 AMP ESC $5.98

I have over 150 flights on a Cap580 Flatout, and bang for the buck its been the best. Like every foamie I have flown, added reinforncement is a given. Some bass wood strips along the fuse, upper wing struts and stips at control horns should do it. Also add some carbon at the wing joint. Get her rigid and she flies well. I find such "engineering" fun, to fly and feel each mod.
I mounted a SuperTigre 370 motor/ speed control from my LHS @ $40. I have over 300 flights on this power system, (lots of hovering with a VFO)...it works great. It hovers the Cap at less than 1/2 throttle, vert is a rocket. Put some 2 inch ultralite wheels on it and takeoff is less than a foot, field landings a breeze. I use a 500mah pack, 5-7 min flights, the motor / ESC and pack run cool. Hang an APC 9x3.8 prop as a good 3D vs speed blend. Use higher pitch and she moves right along. I have intentionally tried to fly its wings off, but she holds. If the wind is over 20 I use an 800mah for ballast.
Many complain about the hinges, which I dont get. They are the best thing about it! Apparently building skills aint what they used to be. These Flatout hinges are far more solid than goofy tape, and far more precise after a hundred flights. All the carbon in this kit alone is worth the price. Repairs, I use Gorilla w/ H2O. Much stronger than CA, but a bit ugly. The beauty of a beater is thrashing her about.
Would I build another? Oh yeah! Its been a great outdoor flyer, in every kind of weather and wind that Michigan can dish out. It puts fun into foamies as I dont have to baby it. It doesnt aero as well as say my very fragile Pluma, but I like flying it more.
Just fly and forget naysayers. Otherwise you may miss out on a lot of cheap flight fun.

I had the flatouts extra 300. I put a tower pro 2410-09Y from headsup RC. With an 10x4.7 slowfly prop. I used an 850mah 3s 20C lipo. This setup worked out great and the plane handled it well.

Need More Glue!!!
