|Thread: Reagle Eagle – from the ashes.|
The tail feathers completed:
Fitted the tailplane with some 4mm ali struts. fitted the wing to ensure it was all square.
Top fuselage decking next.
Fitted the leading edge, still needs a bit of final sanding. (Peter's book page 47) Balsa glued to ribs, sheeting added, then sanded flush. Leading edge added. Very strong and easy.
Trailing edge: bought stock.
Need to finalise my tips. Not yet glued. May have to cut new ones.
I love the formation photo
Some years ago I read a thread (RCMF I think) where someone said they had contatced Cab with regard to buying the rights/licence. Apparently he wasnt interested.
Anyway, I shall carry on. Glued the trailing and leading edges on today. Tomorrow, I'll plane/sand them and fit the tips.
Thanks guys, interesting stuff.
Peter I did use your book as reference whilst constructing my version. Mine is probably over engineered 😎
Bob, I didnt have any original plans or details only what I noted after the crash. I also wanted to use my CAD. It was the first time I actually used it for a new model. I really enjoyed the drawing and cutting.
KC, I saw the Tequilla Sunrise in the book “ designing model aircraft” (same author I presume)
The thought crossed my mind that the Reagle Eagle could be based on that model.

Oh, I almost forgot; the pilot survived
This will be the power: A Hacker A60 V4 190kv. This is my test rig. With a 22x10 APC and a 99A regulator I got 78Amps, which I believe is plenty.
The project has been very off and on, due to other commitments. Now, as we all have to stay in, it looks like I may get on.
I also hope, posting the rest of the build may help me to stay focused.
Years passed but I always had memories of the Reagle Eagle.
In the meantime, I bought a Stepcraft 600 and loved the satisfaction it gave me to produce my own parts.
Last year I decided I would re-build my Reagle Eagle. I still had the original undercarriage, so decided it would be ok to call it a rebuild.
I used my old drawing and produced plans to cut the parts with my Stepcraft using mainly 3mm liteply.
When I took up RC again, I started flying the Eagle. After a couple of years, on a very windy day the wings folded after a tight loop and this was the result.
I was devastated. I searched the interweb for another but alas, none to be found.
I decided I must build one, so made a rough drawing with the measurements.
Some of the more mature amongst you will remember the Paper Aviation Reagle Eagle. A kit sold around 1990 if my memory serves me well. It was made from foam board covered with thick paper.
It was my favourite model of all time and I fitted a 26cc Zenoah. It spent many years after the build hanging from the ceiling of my hobby room as I progressed to 1/1 scale aeroplanes.
Just a picture of my present tug. Based loosley on a typical tug. 2.3m span. ZG62 powered. Built with my Stepcraft 600, so first CAD project.
|Thread: Anet A8|
I am pleased to see 3D printing has made it to this forum. I also have a A8 clone.
I am new to 3D drawing and have found Onshape. Its really easy to use, free and you can export a STL file which is then opened in Cura ( or other slicer).
Only downside (for some) is that it is online only.
|Thread: Dihedral question|
The wing in question has no sweep back, the leading and trailing edges are parallel. It is a two piece wing, each part being approx 1,25 m. The difference in thickness between the root and tip is only about 10mm. The top of the wing is flat.
The question arose as the builder was inserting a wing tube. I asked "what about a bit of dihedral" and was told "it has dihedral"
Hence my question on this forum.
You assumed correct.
Oh well, looks like I was wrong. I thought the whole wing had to have a "V" to be dihedral.
Thanks for the comments guys.
A friend of mine is building a glider tug. I asked if he wasnt going to build in a small amount of dihedral and he said it already had dihedral. For me, it was a straight wing but according to him the tapered lower section counts as dihedral. I find that hard to believe.
Please tell me;
If a wing has a straight (level) upper but a slightly tapered lower part, does this count as dihedral.
(Seen from the front, lower thicker at the root tapering up to the tip)
I thought not but I would like to hear from someone who really knows.

Thanks, something to bear in mind
