Yes Mark, that's a good question. And I could be foolish enough to try that too

. I think I could have done that, but probably with a lot of frustration. The tube is just wide enough to accept 6 wires, I couldn't fit in a seventh. Now if you realise that along the drilled holes there will be a small dent into the tube reducing its inside diameter. That would mean that 6 wires will not fit anymore. I guess I could have tried it with three or four wires, but fact is I did it with none:
Then the tube was glued to the right hand side and the 6 leads were bent and fitted to the magneto. Also I glued the plug leads in the holes, but as the plugs are still missing, they are not yet of much use 
So before drilling the holes I have glued 6 wires in one side of the tube and after the holes were drilled and the tube glued to the cylinders I just glued a wire in every hole.
Now there is another challenge waiting for me and I do intend to follow that one: I am planning to make the control wires from the control stick and the rudder panels all the way to the rudder and elevator through the fuselage. WNW has provided holes in the fuselage to do this and also in the elevator for the upper control wire. The only thing is, is that these holes are there with an angle of 90 degrees to the crossed surfaces instead of a much smaller angle

. But for this exercise it will have the same effect: nobody will see the difference whether these lines are connected correctly or are there just for cosmetic purposes. So now you may also understand my question in another topic for a pin vice to accept small drills

Thanks for the compliments for drilling the holes in the tube, but that goes to the milling machine. I know it is quite an investment (I estimate the Proxxon MF20 at about 300 USD), but it is always a good investment to buy proper tools. And at that price it means buying one modelloco less or 3 or 4 less WNW kits in your stash

I must wait for the etched nuts to arrive to proceed with the spark plugs. Can't wait....
