Robertus, can you give me any information on the angle you mounted your edf on ?
I'm modeling up a YaK 15 and I see that the prototype shows a definite upwards angle.
I'm assuming this is to stop a nose up attitude when full throttle is applied (?).

Thanks.

I don't have any angle. I'm aware how engine was mounted in real plane. I read that plane had a tendency to climb as well. In my model to prevent nose up force, especially during hand launch, I have mix throttle-elevator.

Hello
This is my first post here. After when Robert posted photos of my Yak 17(W) "AGATA", I decided to send couple more photos and informations.
My Yak 17 is based on Robert Yak 17 plans with modifications. Is powefred with Change Sun 70mm Ducted Fan 12 Blades with EDF 2839 motor kv2600 and 4S 3000mAh Lipo. Take-off mass 1450g.
There is two pilots in cocpit and full set of lights on wings and tail.

Yak 17 (W) was a civilian airplane (if there was any civilian airplanes in socialistic country), in service for "Instytut Lotnictwa" (Institute of Aviation) and have an woman nicname "AGATA" (Agatha).
At this moment airplane is in Polish Aiaviation museum in Cracow. More informatiotion You can find here:

elevators


I'm hoping this thread is still being monitored. I have read the entire thread and I do not understand how the two elevators being on two seperate pieces work together as one control service. Do you connect the two with a CF rod? If so, I would expect to see a place in the rudder where it must pass. Any help is greatly appreciated.

The elevator pieces are joined by pain strip, like in the picture
Just cut the rudder, then make elevators, then you will se where you have to cut hole in the rudder.
