Wing centre panel partially constructed on the plan using the right panel as a guide. Used 1/8 balsa on the 2 inner ribs as Danny suggested.

Decided to go with teachers method for wing panel joining, 6mm tube outer in the spar.

The the spare was cut through to seperate the centre and outboard panels. A test with 4mm inner tube shows alignment spot on - very pleased with that yes

Will use the spare ply ribs for the outer panel root ribs.

Hi Furites

Been a while but slowly chipping away at things on the Fury.

Lower wings finished using same techniques as other builders, my outer panels join to the centre section using carbon tubes at both spars. Test fitted, nice alignment with wing cutout.

I cheated with this, the fuselage sides come down to the cross grain bits that i fitted first, I guess it wont matter too much once covered.

Here you can see I messed up the fuselage side to stringer join - set the side peice too high, may cut it to size along the blue line.

More work on the forward hatch and gun troughs

Blue filler to form the lower forward fuselage shape. This area is a bit confussing - do the the lower fuselage sheets fit inside the frames ? I guess so, this gives the opportunity for a lower access panel to the battery compartment.

Upper wings started, these will be in three peices, joiners like the lower wing. Comimng together quicker after the lower wing experience. Decided to use some spruce for the forward spar caps - maybe over engineered.

Also started to think about the wheels / tyres. From what I can find out the wheel and tyre sizes on the plan are actually quite accurate (I stand to be corrected) Not sure if any of the group photographers have any pictures to confirm ??

The wheel scale thickess just looks to thick so I'm thinking of going slightly narrower, the tyre "overhangs" the wheel a little too.

Got these ply discs laser cut by SLEC, really nice clean work yes Black foam from Mick Reeves although maybe neoprene cord would be better - struggling to find 22mm stuff though crying

It looks excellent Martin. I’m pretty sure the 4 5/8”/115mm wheel diameter is right, also for the Spanish version. The Dubro vintage wheels are very close to scale I think, except for the lightly moulded spoke simulation which is easy to get rid of. I’ve got the idea for making a pair of sprung wheels as an experiment as well, but the tyres bother me. The Dubro tyres are excellent and very resilient, but I’m reluctant to scrap a pair of those wheels for an experiment. I’ve used foam tyres on light models but they don’t wear well and aren’t very good as springs/shock absorbers.

Hi Furites

Slowly progressing upper wings, now all framed up and starting to add capping strips, shrouds etc.

Very much copying Danny and other builders.

upper wings.jpg

Used the same carbon sections as Danny for the centre joiners, had the same sizing issues but the rod sands nicely when spun in an electric drill

My right angle dremmel attachment took care of the centre section spar location holes for the cabane securing clips

Need a bit of help with the upper wing outboard trailing edge S1 and S2 parts. There must need to be some shaping here or have I completely mis understood how these parts should go together ??

I can see that there still needs to be the 1/16 sheet shroud to go on to the trailing edge peice but there still looks to be a bit of "extra material" on S1 and S2 ???

If anybody can offer some advise I'd be very grateful

Looks great Martin

I found it easier to do all the cappings first. I added some meat to s1 and s2 as Andy did. But then sanded much of it away again. Wing it

Cheers

That 90 degree drive for the dremel looks brill I NEED one

PAR group does neoprene foam chord at 25mm diameter, just need to sweet talk them out of some

this is my wing tip area around S1/2

Hi Furites

Quick update, a bit more progress, ailerons finally just about constructed and hinged. I'm following Danny with RDS so this all looks familiar looks familiar. Still need to cut a channelon the wing tip trailing edges for the outboard hinge rod.

Nice fit of the ailerons with the frise aileron effect noticeable with up aileron. RDS pockets also started. i'm seeing almost an inch of up / down aileron deflection possible so plenty me thinks ????

Some reinforcing with carbon sheet

cabane bolts support.jpg

Elevators joined - G10 horn and square section carbon rod

fury elevator joiner.jpg

Still pondering rudder and elevator servo location but plate made and tried behind F4.

Aligning the plate with the fueslage structure join seems like it will provide good alignment for the elevator control rod and rudder pull pull cables to the rear end ?? The plate is a lamination of 1/16 ply & 1/16 balsa the 1/64 ply underneath then some small 1/16 ply plates for the servo screws..

Also done a little "rigging" - horizontal stabiliser located and secured with dry fit skewers, this will eventually be glued to the support plate. Just wondering if we need to have the vertical stabiliser off set to the left with our electric power train ?? Any advice gladly received.

Hi All

I'm looking to use Danny's RDS solution for the aileron control.

I have a pair of HiTech HS125MG thin wing servos for this.

They only come with single arm horns and the servo output spline is not the same as for example the HS225MG so I cannot use a 2 or 4 arm or disc horn from these on the HS125.

I cannot seem to find anyone who supplies after market horns with this spline size.

Anybody come across this or have a solution ? Any help appreciated.

regards

Martin

If that link is correct then the arms from the mighty feather servo, the HS65HB should work.

Just so happens I have two sets of extra arms in my hand, do you want them to try?

Just for info, Servo Shop aka Steve Webb Models sells the servo arm kits, the one for the HS65HB is only £1.95 just need confirmation that they fit the 125.

Went in the post box 10 mins ago Martin, let us know if they fit?

Cheers

Hi Danny

Servo horn set splines were a perfect fit - i owe you one yes

RDS fittings now installed onto the horns

Hi All

At last managed to properly bend the cabane struts. Yes you can see my many failed attempts !

These turned out to be not quite the shape on the plan, I suspect my wing spar clips were possibly fitted slightly out. Done now so well pleased. feel i can move on.......

I can thoroughly recommend this wire bender, Fathers Day hint worked a treat wink

Slight change of plan with rudder and elevator servo locations.

The elevator pushrod is a 6mm carbon rod with m2 threaded rods JB welded in.

Access to fittings through the "scale" empenage access panel

Progressed the cabane hatch and struts.

A little filler was required on one side of the sheeting to get a good match at the F4 / F3 areas. I then glassed the sheeting as I intended to use foil covering.

Used solatex to wrap the strut, stuck using dope, hope this stays put. Its not as easy / flexible to use as I suspect silk would be and does not like to conform to the more complicated ends of the struts - may have to use some silk to finish off this area.

The brass anchor points have also been installed.

Decided the surface was not flat enough for foil covering so tried a little lithoplate work, play stopped for the day as HWMBO has returned and is not keen on me using the gas hob to aneal the lithoplate sad

cabane3.jpg

All very similar to Dannys, but then I am still an apprentice. frown

Looks great Martin. I try not to aneal the litho on flat sections, it holds its shape better. I am not really sure why I am mixing litho with foil, not sure i will be happy but its fun to experiment

Cheers

Danny
