Re: Pieter Visser's X350

Just keep sanding, filling, sanding, filling... :lol:

Amazing when it starts to smooth out, really cool, but yeah, don't underestimate the effort it takes ;)

Re: Pieter Visser's X350

Not much progress to show, or nothing the camera will do justice. I've been sanding and filling the rudder to smooth it out in preparation for painting. It takes a bit of time, mainly as the micro dries overnight and sanding is only the following day, so it is a slow cycle. It is amazing to see how ...

Re: Pieter Visser's X350

Started filling in the rudder trailing edge with micro and smoothing out the rudder skin. I had my bench vice on the trailing edge straight edge at one point, but it fell over and onto the rudder, putting a few indentations into the skin :( Fortunately the micro will smooth all these imperfections o...

Re: Pieter Visser's X350

To ensure a good bond on the trailing edge, I finished it off with peel ply and forced it down with a straight edge. The peel ply is good as there will be micro filler used later to finish off the trailing edge. I put toilet paper over the peel ply to absorb excess resin. On all the edges I used pee...

Re: Pieter Visser's X350

I covered the trim tab section that should not be covered with carbon as protection while putting on the last skin layer 300gr bi-ax. This was cut years ago and fitting it again was a breeze. After fitting the skin, I started spreading out micro over the polystyrene, top half first, folding back the...

Re: Pieter Visser's X350

As I will only do a single layer of 300gr bi-ax carbon covering over the rudder, I put some UD over the counter balance horn to add a bit of strength. Added a layer UD on the top over the counter balance horn extending onto the rudder and another layer on the bottom going onto the rudder leading edg...

Re: Pieter Visser's X350

Removed the straight edge and peelply and sanded the area to apply another layer of UD. This trailing edge is going to be stiff when all is done ;) I use packaging tape to protect the trim tab from resin overflow, so it should be easy to clean up for final painting. One more UD after this one, smoot...

Re: Pieter Visser's X350

Finally back to work on the rudder. After replacing the VStab fin skins with the carbon ones, I fit the rudder again to make sure of the fitment and the width at the counter balance horn. Thankfully this seems to be good. I did take of very thin layer of foam from the side still to be covered to com...

Re: Pieter Visser's X350

Not much building going on, but moved the wings back to the dolly to free up space so I can start working on the rudder, H-stab, ailerons and flaps. This is mostly sheeting work, but I look forward to getting it done so I can start the assembly, after which my Whisper will really start to look like ...

Re: Pieter Visser's X350

Wrapped the spar box, which completes this step of the wing build process :D 3 times around with 180mm by 2100mm 500gr UD finished with peel ply. My box cir-cum reference was about 68cm, so x3 and rounded to 210cm to ensure a bit of overlap. This was done after 4 layers 400gr bi-ax was put around th...
