I made hard board templates to remove excess EPS foam from the lower section of the rudder. Firstly I cut the rudder in 2 halves on the centre line we originally made to line up the cutting templates. After cutting out the excess sections, I rejoined the 2 halves I removed in order to mark and cut ribs to put back in order to provide more strength and support. Idea is to glue these sections back and rejoin the two halves of the rudder to have it complete as before, but obviously significantly lighter. I will weight the total of foam removed. I suspect I'm looking at at least another 100gr. So in total, with the leading edge and main core, I guess I'd save around 200gr+ on the EPS only. The carbon covering should save another 30% I imagine. Keen to get the finished result and put it on a scale for comparison :D

Can confirm that 200gr of EPS was removed in total.

Shear web part came in 2/3rds of the orginal part weight. This weekend I aim to start sheeting the rudder in carbon and I'm really excited to see it done and on a scale to see if all this effort and cost was really worth it... :?:

It looks like you will need very little lead in the horn mass balance Pieter. I will be very interested to see the final weight.

I am also anxious to get the final result, but what I've found was that I've added back around 50g of weight in the form of micro :shock:

So like most things in life, there is always a balance, but I do believe I'll save quite a bit of weight. I'm aiming to get in at around 70% of the original part, so let's see...

Last night I glued the rudder trailing edge onto the shear web, after cutting areas I want to add rovings. So my rudder is nearing completion, but I also still need to shape the counter balance horn, which is going to be a challenge for me and stretch my non existing artistic skills :lol:

Can't wait to get this rudder covered and on a scale!

Over the weekend I got to doing the rudder rovings on the one side. This week I'll do the other side, make the counter balance horn and final fitment on the a/c before covering the rudder :D

A motivational pic attached.....to prove that even a project as daunting as this does eventually have an end.....and it sure is worth the effort :D

In this day and age of instant gratification there are few souls left on the planet with the staying power required....a unique breed of human indeed :wink:

Oh WOW, that looks GOOD!!

Thank you, Russell ;)

It is quite a project, but I'm absolutely loving every step of it. I cannot wait for the day I can take a picture like that of my a/c and it WILL come :D

At some point I need to take a weekend and fly down to PE to take a look at your Whispers! I've some ideas around locking the canopy and I need to practically see how a couple of things are done and just get some more inspiration :lol:

There are far to few pictures and clips on the internet with Whispers!

Hi Russel....

Awesome! The best looking,flying single engine low wing aircraft on the planet! Soon will start posting my progress...

Blue skies!

Last night I did the rovings on the other side of the rudder and finished with micro and peel ply.

So now it is final fitment and measurement and constructing the counter weight balance horn and finally, covering :D
