Have not flown it in a 190, but flew those in Slow Sticks, and Epaya sells them for the smaller GWS warbirds. It will fly the 190, but it is only good for about 150-160 watts without building up to much heat. I think you will be happier with a little over 200 watts.

I posted up the united motor I'm planning to run, and expect it to be good for 220 watts without issue. Price is about the same as the motor you are looking at. Clark is flying his 190 at about 220 watts and performance is good. Not over powered, not under powered, very nice. To launch his plane, he grabs it near the canopy and gives it a slight underhand toss with the motor on, plane pulls out of his hand. (We fly without landing gear in our thick grass field.)

(I'd link to the United motors, but their site is SLOW again.)

Hi taxdodger,

I'm afraid your FW-190 would not be happy with a flat tired
pilot.

I am using this motor with APC10X7E prop.
HXT35-42C-1000
HXT 35-42C 1000kv Brushless Outrunner (eq: AXi 2820
https://www.unitedhobbies.com/UNITED...idProduct=3884

Like Wayne said, It's good. I can launch it with about 70-80% throttle.
I may try 11 or even 12in. prop. this weekend to see the defference of the vertical climbing.

Actually it's not.
With this motor and a ThunderTiger 2200mah lipo, the 190 blances well.
When it spins the 10X7E prop, it only draws about 22-23AMP.
The only thing I am concerned about is that the motor is too big to fit the GWS plastic stick motor mount.
I can only put two screws to fix the motor, which is kind unsecure.
But after about 20 flights so far,the motor stilll stays there. No problem.

damn.....

that's a big motor.. I use the 35-36 version in my magpie AP 40oz AP plane and the formosa II. My 1350KV version of that motor is a monster. With a 9x5 prop I run it at only 30% throttle when taking pictures.

With the 1000KV version you could probably swing a 14inch prop with no issue or a 3 bladed 12inch mmm big props.

Very nice paint job. It will hold up against any other FW on the market, especially those costing 3x as much. Glad to see you got the COG dialed in. I'm noticing the bigger GWS warbirds are a lot more tolerant of COG errors than the older ones.

Right at the stock recommendation - 85mm from the front of the wing, basically right over the wing spar.

My CG is, at the 90mm, is 5 mm further back than that used by jamesdr. This is recomended by GWS as the rearmost position. This is where the CG came out during the build. I use a lighter 2 cell battery so this is the reason for the difference.
