Re: Pieter Visser

Made hard board templates for the aileron bell crank and the rudder pulley. Then cut a section of polystyrene for the pulley bracket and made a carbon layup: 11 layers 300gr bi-ax carbon. Before the 12th layer, the resin started gelling, so I stopped on 11, but this is one SERIOUS layup! Rolled out ...

Re: Pieter Visser

Glued the bronze wing pin bushes onto the rear spar plank, so not a big work day, but at least something was done ;) The flange areas of the bushings are put against each other for this clamp and cure to put pressure on the busing when the planks are clamped. The front plank and bushings was already...

Re: Pieter Visser

I did the strengthening of the rudder attach points today, as well as cutting carbon for the elevator pulley bracket and the aileron bell crank brackets. For the rudder attachment points I decided to use 5 layers 300gr bi-ax carbon for the upper and lower area and finished the job with peel ply. To ...

Re: Pieter Visser

The engineering shop will only open on Monday the 15th, so my bronze bushings are lying idle and so am I :( Thus, decided to do the strengthening of the rudder attach points, the Hstab area and I also decided to add a little more strength to the area where the elevator pulley will be mounted, before...

Re: Pieter Visser

While waiting for the engineering shops to open, I decided to glue the RH carbon fin skin. This replaces the standard fiber glass skin and the RH and LH skins combined should save around 800gr of weight in the tail section, which is fantastic! It came out beautifully. The Whisper factory did a great...

Re: Pieter Visser

Using a new 41mm hole saw blade, newly purchased with the arbiter (no drill bit, but a 6.5mm seemed to work just fine), I then drilled the wing bolt holes. This was after I used a long 6mm drill bit to drill the spar plank pilot holes into the wing spar, FROM both sides. It is important to drill fro...

Re: Pieter Visser

I then needed to set the dihedral. With the wings level at the center at ZERO incidence, measuring and setting the dihedral is not too hard. I setup the left wing with the wingtip 18cm higher than the center and then used the laser to set the level of the RH wing. Setting up the laser and then swing...

Re: Pieter Visser

As I've lost a lot of build time with the relocation to NZ, I decided to have the wings constructed by the Whisper factory, which saved me a LOT of time and they look great too :) The challenge I found is that with the wingtips on it is not as simple as setting the wings up in the wing jig to get th...

Re: Pieter Visser

The time has come to start the wing carry through spar box. This was my thoughts in December, as I was going to have a glorious 3 weeks of leave and lots of building to do :D Sadly, this task is still ongoing and I've not completed it during my leave, although I've made good progress, life happens a...
