Yeah Phil,

I am happy with it ,but i'm more and more thinking the torque rod way .

I think its a quicker build and the pushrod-horn sticking out of the wing is becoming more and more a thorn in my eyeteeth.

Thinking and mesuring for the cockpit details got me investigating some boxes full of junk and look what i found...

A genuine Belgian air force parashute !

Would't that be a great scale item ?I feel i have to......nonono that's overkill...Is it ?On the other hand....

Dirk,

Will your pilot be ejecting for some reason?

... it might have something to do with the stormy weather we have at the moment, but some guys from around Sint Niklaas, BE seem to become seriously 'winded up'... surprise

Parachutes, Migs around... well, well...

Cheers

20200209_224816.jpgNo worries Chris,we'll be safe with 25 sabre's aroundwink.

I finished the second aileron servo connection today...The list is getting shorter !

Another item on that list was giving the rudder a more scale look altough it's not operational.

I removed te part that's normally moving,bevelled the edges and added a little block(the part in front of the hinge line)20200209_224805.jpg. Both parts will be glassed apart and glued together later. It's atleast more realistic than a panel line

Neat work, as always Dirk.

When posting photos I always start by inserting a series of lines with just an x on each:

x

x

Then, put the cursor after an x, insert the photo and change the x to a suitably witty caption. Move on to the next x for another photo.

Yes agreed. The key to photo insertion Dirk, is that before inserting the photo insert your cursor at the spot in the post where you want the photo to appear. So if you are inserting photos one after the other, you have to insert paragraphs so that the photo will be positioned at the right spot.

Thanks for the tips Steve and Peter !

Today i hooked up the elevator and brakes servo. Everything worked as planned and at the end i saw my brakes work for the fist time via the servo !( and the elevator)20200211_231241.jpg

With all the servo's installed,i was planning to permanently install the fin and rudder but i still have to close the bottom of the fuse .I realised that would be a pain with the fin in place.

So ,first a little last planking or better a little hatch ?I hate the idea not being able to reach the elevator attachment in case of problems !ideaAs i don't want to add weight ,i kept it simple :I prepared a piece of 4mm balsa that fits the opening in the fuse. Then added two pieces of plastic snake wich will serve as two little dowels.Drilled two holes in the former where the dowels go in ,and formed a little ''lock''at the back side.Nothing left to do than just a little sanding. Voila !20200212_231802.jpg

All in place it looks like this .I reinforced the hatch with a small piece of 1mm ply in the front.20200212_231740.jpg

The hatch will be secured with a little screw via the exhaust20200212_231823.jpg

20200212_231840.jpg

Two more things before the final sanding! The fin and the canope. Stay tuned !moon

... splendid, your idea of the access hatch, Dirk. yes

Great idea Dirk. As I have already cut a hatch in my fuselage, I might as well make it removable. I think I will screw mine down then cover it over so it can be accessed in an emergency. There will then be no gaps for the wind to whistle through.

Hi again ,The last item on the wooden airframe is to fit the fin and rudder accompanied with the fillets. The fin was fitted earlyer so that's the easy part. i glued it in with epoxy because cyano could run onto the belcrank and we don't want that ! Later i fitted some triangular balsa strips over the joint.The hard part is sanding these guy's ! For this i made-up a special tool.Well special...It' s the non-threaded part of a 10mm bolt welded on a large nail who fits in the handle of our perma-grid files.On the 10mm cilinder i welded a flat plate.

20200214_210913.jpg

The idea is to wrap a piece of sandpaper around the cilinder and secure it with a little clamp.

20200214_210932.jpg

To my surprise it worked very well !With this tool it's easy NOT to touch the parts beside the fillets. Easy to handle too !

Today i started on the canope works teeth.Not my favorite job !!

After a lot of mesuring and fitting i decided to make the rear part remouvable , i may regret this later but hey ,no guts no glory ! I drew a line where the dividing has to be made . I had to cut with scissors because i can't lose a mm of the canope,it wouldn't fit proper(like with cutting with a disc ).I took extremely care,not to damage the plastic.

20200213_215124.jpg

I then placed the front part in the frame and marked the edge of the front canope part on the inside of the frame

20200213_215201.jpg

20200213_215524.jpg

The photo makes the line look out of place but i double checked , it's fine .The idea is to place the frame on the canope in a way that the aft canope part slides under the front part of the frame. It will be clearer later...Like the plastic canope ,the epoxy frame lets itself cut best with scissors.

With this precise job behind me,i realised i have to finish the interior first so i looked up some examples on the net and did my best to copy the front part first.

Great update Dirk, superb canopy work - is the canopy going to be sliding on rails as per the full size - or just removable for RC access?

Any job that requires a special tool making to get that perfect finish is always a rewarding job - and you've certainly achieved that with your 10mm bolt and plate! For me, welding like that would be a major task, I dont have the kit at home, I guess to you in your business applying a few spot welds is no big deal!

Hi Phil , the canope will be held by magnets . I like the possibility of having access to receiver and switch without removing the wing.

As for the tool ,you could make it in hardwood too i guess,and glue in the handle.

It must be one of the best tools in my toolbox !

Just something in between while i'm waiting for my pilot to arrive :Has anyone gave it some thought to replicate the gun ports in the front of the fuse ?

20200216_151627.jpg

Well i did today and i realised it's not going to be easy with the former on the inside.I ran a little test on a piece of scrap balsa .I drilled a hole with a round perma grid file until i could slide in a 8mm carbon tube.Glued it in and sanded off the tube part that sticks out.Not bad for a first test .

20200216_172928.jpg

Any thoughts about it ?Suggestions ?How about the size ?

20200216_210527.jpg

Cheers , Dirk.
