Prime RES 3 building advice

Hi expert Aloft builders. I am seeking advice about servo mounting and spoiler wiring connections on 2meter res glider with a very tight spaces.
1. When rudder and elevator servos are mounted on diagonals is there a typical way the servos are oriented. The servos are very close to where the bowden cables exit the boom tube. I have played with the options but have never mounted this way before so thought I would get some other ideas. See photos.
2. Also not sure how to make the connections at the wing junction for the spoilers. It is very tight. I think I will need some type of a micro connector rhat I can push back inside the wing. See the photo with the mpx connector for reference. Any help is appreciated.
Tom

I'm not sure on the best setup for this model. I'd need to see a bit more of the details to venture some suggestions. But here are some basics - The bowdens should be pretty straight, pointing right at the end of the servo control horn. The servo control horn should not be able to hit the other horn or servo. Typically the output shaft will be up against the side of the fuselage with the servo arm going straight across to the other side. Depending on the control horn on the flight surface, you may not need a very long servo arm.

Do the plans show anything?

I will just have to play with it and figure it out. The plans and instructions do not cover any of this. They also have nothing on spoiler articulation. I assume the spoiler servo arm can just push up the spoiler. Quality of the kit is good but probably not for first time builders.
Thanks for your input.
 
I think this German thread should be a big help. I did not read through it, but sounds like they like the plane a lot and saw servo installs and spoilers mentioned.
 
Thank you for the link Wayne. I did find some info there. Someone used a 3 pin pogo connector (see photo). What I did not realize is that the non motorizes version jas a completely different fuselage. It has a ballast box with a hatch above it. The motor version has the rudder / elev servos mounted upside down with a hatch on the bottom. I think I may build another hatch above the spoiler connection in case of future problems. Thanks again
Tom

They also have build threads for the electric version there. Was not sure what you were building.

Here is one of them. I didn't see any photos of the servo install.
