Colin’s Spanish Fury

Thank you Danny, your comments are noted and appreciated. This is moving now, I’m able to put in regular hours at last!

I’ve struck a problem that I’ve shared with Danny and he has sent me some helpful detail. I’ve lost a couple of days trying to understand why in attempting to set the upper wing incidence using the jigs made up from the plan, the fuselage section made up from F3 and 4 was about an inch up in the air from the base board! The 10swg wire cabanes are accurate to the plan. I’ve finally understood that the wire dimensions on the plan are drawn to the vertical spacing and make no allowance for the true diagonal dimension. Ridiculous, how can that be? Fortunately I’ve got enough 10swg to re-make them when I’ve worked out the accurate dimensions, but could have done without this.

That is most peculiar Colin, I can understand what you are describing but why haven't the rest of us hit this issue?

I made mine from the plan.

Anybody else want to chip in here??

Made mine from the plan no problem noticed.

I had a problem (see my post in October last year). I felt the rear cabana struts were too short. I cannot remember whether I remade them or not. The interplanetary port strut rear leg could be about 5mm longer as per Danny’s RCM&E article. By the way I really enjoyed reading it.

I made mine with wire bent using the plan and wire bound the struts but didn't solder. I didn't use the jig. I measured directly from the plan and triangulated the wing to fuselage rear to make sure it was straight. Tack soldered to hold it steady then soldered up after the wing halves had been removed.

I wonder if the squiggles on the cabane wires drawn on the plan (you can see them in the photos previous) have got something to do with it? I didn’t do them, they’re on the printed copy. Are other plan copies the same? If I use them as drawn, the upper wing will be too close to the fuselage. To position the wing correctly, they have to be longer, so I’ll work that out myself. It definitely ain’t right.

Colin the plan that i used is on aerofred, that plan does not have squiggles.

I would suggest you download the Pdf and check it.

I have a plan printed from that pdf you are welcome to borrow it?

Where did you source your plan? There were others that also found errors, that were not present on mine.

Cheers

The wood and plan came from somewhere I’m not allowed to say (can I say that now?). I’m measuring now and can confirm that the wires as drawn make no allowance for the diagonal span-wise or the forward angle from the vertical. I’m wondering if the copy I’ve been sent is from when the error was identified but not corrected? Let me have a look at Aerofred and see if I can download the pdf. If I can’t I’ll gratefully accept your offer.

Thinking about what I said, the wood came from where I said, but I think the plan came from Sarik.

I’ve just down-loaded part of the AeroFred plan and the difference in the cabane wires is obvious, not just in the dimensions but in the relationships between front and rear. I’ll plough on from here, but it will be a job for tomorrow now.

Phew

Glad you have an answer.

You probably dont need the paper plan, just print the bits you need

But you are welcome to borrow mine if need be.

Cheers

Danny

Thanks again Danny, that’s what I did. I’ve got what I need now by the looks of it.

Call it paranoia perhaps! Even so I thought I’d sit down this evening and work out for myself what the cabane wire dimensions should be to achieve the correct position and incidence for the upper wing. I’m very pleased to say that my numbers worked out within 2mm of the measurements on the AeroFred download, so that’s me sorted out for a day in the shed tomorrow. Once I’ve got this bit done I can solder in the diagonal braces into the cabanes, then I’m leaving all of that to get back onto finishing off the fuselage. At last!

Keep going Colin. Looking forward to seeng the completed Fury.

Graham

The diagonals I didn't find were accurate Colin, and dimensioned my own, but I think I documented that?

Cheers

Danny

Thanks Graham. So am I!

Danny, I can’t remember, I’ll take another look on your thread. Once I’ve got the incidence set, I’ll make the diagonals to fit rather than work off the plan anyway.

I’ve considered this bit to be a hurdle, but I’m over it now! Cabanes set and soldered, incidence and stagger correct. I’l solder the diagonals in tomorrow, then back onto the fuselage.

Don't forget the servo leads when you clad the cabanes Colin . I did I think I was so relieved to get them set right to the jig.
