New former F6 cut from the scrap ply from which the old F6 came from, it was simplest this way

Thanks Tony

Richard Dalgleish told me he had the 3/8 wooden beams snap when attaching his wing one time, and advised upping the wood thickness. I have subsequently added two strips of 3/8 x 1/4 to each beam.

Whilst that was drying I moved my attention to the tailskid.

I contemplated making it sprung, but couldn't justify the effort, I know I will regret it but it is done now.

fury98.jpg

looks a bit scrappy but is solid. I have used 14SWG as per the plan, bound with Kevlar thread from Mick Reeves. Thtead is locked in place with thin CA

I know Richard said his broke and suggested a heavier gauge but I thought if I leave the lower section un-bound then the flexing would be over a larger area.

Time will tell......

Of course Richard puts hundreds of flights on his models, mine barely fly a couple of times a year sadly.

Cheers

Danny

The beam strengtheners were solid enough to be worked on so they were drilled and the blind nuts fitted.

I have been looking at the photos again and it appears that as somebody already pointed out, there is a middle stringer on the top centreline of the fuselage, not on the plan. I will have a look at the spacing and see if we can get away with adding one or whether it will mean re-distributing all of them......

Cheers

Hi Danny.

Nice work.

I think the problem of broken tailskids/tailwheels is a commom isue of glow powered models. A few years back I have a Great Planes Super Sporter 20 powered with a O.S. 40 Four Stroke. The force to restrain the model for starting the engine and some armonic vibration shed a few tailwheels until I changed the engine for an electric motor.No more lost tailwheels. Just my two cents ¡

José Luis, you are quite right, I had forgotten about the loads involved during model starting and restraint! My excuse is I only do leccy. You can have a point!

I have cut additional notches in the formers, on the centreline. I used a small Permagrit file.

More stringer detail:

First I added the lower 3/16 stringer that doubles up the lower fus longeron. It was made from one piece of 20mm wide section of 3/16, which I then divided diagonally to give me the two triangles. Note the forward part tapers into the wing seat, and the rear abuts F11.

fury105.jpg

fury106.jpg

I didn't slot F11 for every stringer just added two, and I added a central stringer notched into the fin seat. I haven't cut the slot as it will need checking to include the rudder offset, you hadn't forgotten the three degree rudder offset had you?

fury107.jpg

fury108.jpg

I will fill in the side stringers next, but we also have to be wary that we don't block access to the fuselage insides for the pushrod/snake runs.

Cheers

Danny

More stringer work.....

fury110.jpg

With the side stringers I was a tight sod and actually scarf jointed some strips of scrap together to make up longer strip, the waste otherwise would be too much. I made all the stringers from a single sheet of 3/16 stripped.

fury111.jpg

Also of note is the side formers at F10. they are marked for the position of the notches, not cut. I found they were spot on, but worth checking your positioning.

fury109.jpg

fury112.jpgOn to some sheeting now, I am anxious to see how the line flows through the centre section through the cowl area. I think I need the lower wing before I can do the wing seat area.

Cheers

Centre section sheeted, just need to cut open the gun troughs.

I have just used stiff paper for this as the trough will probably get lined with litho plate.....

A modification I would advise here. Before sheeting the top of the centre section, add some stringers at the edges of the trough, that way the sheeting has something to stick too when you cut the troughs open. Better still pre bend the balsa, which is what I should have done. Wet the balsa and tape it to shape. when dry it will be close enough that the stress will be non existant. Then attach it and sand to size.

I may yet have to tear my sheeting off and redo, we will see......

Cheers

Hi to all,

Is it just me... or did The Chief take some Gonsalez's pills today?

Hi Chris, i have been mulling over lots of the build in my head and have made decisions, so now I have a plan of what I am doing i can forge ahead.

Stringers trimmed to length, and the rebates sanded in preparation for the cockpit sheeting.

I am going to sheet from F5 to F8 using wide planks, I think Jose has done well to sheet the section, I am not that good and the unsupported section between F6 and F7 looks like a recipe for disaster.

Once the areas are planked then the stringers can be sanded flush to the 1/8

Cheers

Danny

Superb progression, Danny.

Looking forward to your 'wide planks' solution.

Some times ago your were raising the question (to yourself) that there was quite a gap at the starboard side with - I think - the F6S counterpart 'missing' at that side... (?)

Did you 'insert' one as well there?

Cheers

Chris

I just taught I would possibly be able to remind you that second F6S, Danny.

... and, very conveniently, get rewarded with a 'house' point... angel

BTW, did you make an Excel file to keep record of those extra points for the Fury Pupils? cool

Cheers

Chris
