Aviomania G2sA-2 build

Thanks, Chook, I'll see if that space is open near my fuel pump. Did not think of that...

No, the Aviomania does not use a belt on the prerotator; it uses a rubber wheel that is pressed (friction) against an aluminum drive wheel.
The rubber wheel is directly connected to the flex-shaft.

Hmmm. have I got it wrong.
Looking at your gyro from the rear your prop spins anticlockwise which will reverse the direction of the flex driveshaft spinning it clockwise.
When the bendix engages the rotor drive it will then reverse the direction of the rotor drive drive causing it to spin anticlockwise (looking at it from the bottom). Your rotor needs to spin clockwise when viewed from the bottom.

I'm looking at the photo and based on the pitch of the prop blades I'm seeing it spinning Clockwise from the rear. This would cause the friction wheel to spin CCW. Seems OK to me.

With the prop hub on my 912UL it won't work, inner bolt circle is blocked inside the hub.

The prop pitch has not yet been set (sorry for that confusion), but the Rotax 912 rotates counterclockwise when viewed from the tail in the photo.
Thus the black, rubber wheel rotates clockwise.
There can be no 'reversing' of the rotor drive, its direction of rotation is determined by the direction of rotation of the 912.
Not to worry, it is all correct. (y)

I'm looking through my build videos and could not find anything focused on installing, routing and adjusting the choke, throttle, rotor brake etc cables. Do you have something in your downloads?

Bobby, installing and routing the cables is straight forward. You can find all the information needed in 4 videos in the "04 Controls" folder. The video file names are "3 Throttle System (1)" through to "3 Throttle System (4)".

Email me with pictures if you have any questions.
 
Also details on adjusting rotor brake in "02 Rotor head" folder.... and details on adjusting/ routing the engine part of prerotator in "06 Engine" folder.
 
My G2 received its Airworthiness Certification on a stormy Wednesday.
The DAR used this opportunity to get his DAR certification renewed by Facetiming with his FAA manager who watched from home ('pandemic rule').
All the reviewing was going along well until the hangar's electrical power went out due to the storm while we were about halfway through the examination.
The heavy rain also presented an audio challenge as the big drops pounded the metal roof.
We finished under a fading flashlight, but both the G2 and the DAR received good marks. :)
Quite the memorable event.

There are still a few bits to tidy up on the airframe, but I am mentally switching to flight test preparation mode.
Engine start, systems checking.... prior to the first flight, also I plan to do a bit of refresher training with a CFI and review my test plan with him as well. First flight hopefully late November timeframe.

Thanks Nicolas, I watched the videos again but could not find anything on routing the control cables back to the engine.

Excellent news - well done
 
Fantastic. Congrats!

It's time to start shopping for a snowmobile suit for winter open-cockpit flying. 50 degrees is about as low as I can go and that's only a short flight. The wind always finds a way in.

3C was the lowest I have tried on a Bensen. Multiple layers and three sets of gloves and it was my hands that caused me to terminate after about half and hour. I simply couldn't feel the stick.
 
Congratulations that is awesome news!!

Minus 4c for me, and even with a short muster of about 7 hours in the saddle it was a still a long day.
Even with multiple layers my toes where still numb at lunchtime, really takes the fun out of flying.
