Flew G3PO in the daylight with the axi.
It flies very nicely.
A flight note, turns take a healthy dose of
up elevator, with right turns taking more than left.
It has a lot of roll/pitch control so its wise to take it up
high and experiment. I will post video on the website
sometime today of the low speed flying with the
axi powered, aerobalsa blade model.
Note that I added a tail boom brace, this pushrod tube
was more flexy than the other one and needed it.
The symptoms of a flexy tail boom are really bouncy
handling on the ground and it tries to lift off too
early.
I'm going to add this brace to the plans, because it
weighs next to nothing and really helps.
Its a bamboo skewer and a piece of 1/4 balsa.
The pointy end of the skewer is wrapped with thread
and CA'd to the tail boom.
ALSO, the axi motor mount let me move the CG forward
some, It now hangs with the mast straight down + 2 or 3 degrees,
i.e. the CG is slightly ahead of the mast. This made a nice improvement
as now you can just feed power in and it will ROG without any help.
It reduced the pitch power somewhat so I may move it back slightly.
My rule of thumb is now mast straight down or a tiny bit more nose heavy
than straight down.
Here's the axi motor mount I whipped out and a detail picture of the head
showing the shaft length, anti-rotation link, and trim setting of the swashplate from
the side. The side to side swashplate setting is roughly level. This was the trim
position during the morning video.
