Hi Guys

Well she’s all finished and maidened.

The control throws in the instructions are way out, (like 45Deg) I don’t think so, so I set up what I thought would be a good start for the airframe, worked out fine for me, I can measure these if anyone wants the info.
CG was set as per the book, on the wing joiner box.

The engine had not been run so I left the cowl off for the initial startup, it took a fair amount of priming and some fuel squirted directly into the carby to get it to fire.
I then used my nitro starter to fire it up which took a few turns before the dry carby was up to its task.
It idled pretty sweet right away so let it run for about 5 mins with varying throttle settings, tweaked the High needle a little to get a transition and then replaced the cowl.

The day was bleak and windy not the best weather at all for a maiden flight.
Taxied it out, and I have found that my Ag planes all taxi sweet with no tendency to tip forward at all, lined her up and slowly opened the throttle, straight down the strip and she was airborne in about 8 ft due to the wind but no problems she just climbed away nicely.
A small amount of aileron trim was all that was required to get straight & level flight.
Did a few circuits and tested the stall, none to speak off, flies great, very much like my smaller H9 Pawnee.

Had 3 flights with 1 deadstick on approach which was no issue at all.
The engine quit due to sucking air bubbles into the fuel line which I tracked back to the tank. It was shaking too much at low fuel level so some remedial work will be done here; also the tank actually slants forward, not the ideal layout.
So a few tweaks and more engine running is in order.

First impressions are good and this will be a keeper for sure, I will probably sell the smaller one, although reluctantly.

Cheers
Paul
