Test flown indoors and outdoors


Here's the finished bird.

I am very pleased at the performance of this model, given it only has a 10g 2000 Kv motor in it.

It flies relatively slow and stays aloft at half throttle. The prop is a GWS 5 x 4.3.

Indoors was quite easy, but outdoors was a bit blustery out. Once I got it out of turbulent air it was very manageable. That means that I could keep it into the wind. Rudder rolls and loops were very easy to accomplish.

At 125g (4.35 oz) she is very light with all that wing area (177.5 sq. in.) and comes in to 3.53 oz. per sq. ft. Compare that to our SEMFF Combat warbirds with 150 sq. in. wing area at 9 oz. gives a wing loading of 8.64 oz per sq. ft.

I am going to modify the design slightly to make the fuselage a little wider. I had to mount one servo higher that the other to prevent the control horns from crashing into each other. 1" wide on the inside, and I'll modify it to 1.375" inside. This will be designed for MPF through out, with 3D printed firewall and control horns. Then I will publish a set of plans.

Had to do a double-take when I saw the 3d printed motor mount. That looks awesome!
