Thank you. You can build models like me, it is very simple but you will have to follow this thread and build your model this way.
Try it and you will like it !! All balsa, epoxy plate and plywood cnc parts are in the kit. Our speedmodels we build to fly on our local field are very strong. After three years all parts have to replaced like engine bearings and servo's but the models are still flying fast and are still strong.

At the moment I am not sure how to connect the servo to the elevators. I am thinking to put two servo's in the tail with a direct connection to the elevator. This must be ready before I can start painting. The rudder will be closed loop with thin iron cable in a tube.
So the elvator is at the moment a problemm.

The belly pan mounting is ready and cnc cut. I will show that. Some parts are glued at the moment.

Mounting of the belly pan:
Glue the two small blocks in the back of the fuse and one of the longer blocks in the fuse front. The longer one will be chopped, this is only to glue in the former straight in the fuse. Use a saw to make the former shorter. Take the four small formers and place the blind nuts with a hammer. Glue them with Zap 5 min/ 30min or UHU plus.

First I wanted to place the servo besides each other so three servo's in a plywood former. Better is to make a former with on the bottem in the middle the elevator servo with carbon Y rods and above that the elevator servo with pull pull system.
Not straight above each other but the elevator servo a little forward so you can see what happens. Both servo's must be replaceble.
At the moment I am drawing it to get a complete vieuw. The elevator rods will get a balsa Y support in the middle.
The throttle servo will come forward.

Marking the formers on the belly pan with a pencil and masking tape. Sand the fuse spots with 80 gritt and glue with UHU plus or JB weld.
When the glue has been dried the holes can be drilled but first tomorrow shopping in Amsterdam with my son for some Pokemon cards.

The servo's are drawn in real size and the top vieuw of the backside of the fuse is drawn in cad with the servo's and the carbon rods for the elevator and wires for the rudder. It is very easy to measure where the stuff ( rods and wires) comes out of the fuse. Even the servo's can be fitted in the fuse when printed in real size:

A hole is made for the elevator rod with help of the cad drawing of the top vieuw with all rods and cables.
The cnc control horn is glued on the elevator with UHU plus but first two holes are drilled in the inserted and glued plywood.
All fits very well and works fine.

The servo unit parts are glued with Elmers white and reinforced with spruce triangle 8x8mm.
A second unit is made with a hole for a switch. The complete unit will be glued in the fuse after the paintjob.
The holes in the fuse for the rods and cables will be made in the fuse before the paintjob.

The holes for the bolts in the belly pan are marked and drilled through the plywood and through the belly pan.
Keep it straight. Before the places for marking are marked on the side of the belly pan with masking tape and a pencil.

When ready tape the belly pan on the fuse and put the drill in the new drilled holes in the belly pan and drill the holes in the fuse
through the fuse and through the glued plywood. Use a needle file to make the holes smoother.

Before the blind nuts were glued on the small plywood formers. After removing the belly pan the holes are ready for the bolts and blind nuts.

Apply some glue on the blind nuts and use the bolts for mounting. Use some double folded tape on your finger for the back bolts.
