Hughes H-1 w/ Racing Wings

Thanks robin ill have to look into that

Thanks jayz and Robin.

jayz, are you updating a build log where I can see your work in progress? I'm going the 'full disclosure' route with mine so everyone can see the obstacles, my mistakes and how I move past them, for better or worse. My first fuse was a total distaster, but I had to go through the process of designing it, cutting it then gluing it together to find out where the inadequacies were.

I had to simplify the nose and make an easy way to mount the wings. Those were my goals in the redesign but other things came out of it - A better tail section and a better way to manage the tail connections to the fuse, including the way the V. Stab mounts to the rear of the last former. I'm really loving the process. Thanks again for the encouragement.

If you have time to share your build, I'd enjoy seeing it.

This is what I'm talking about! Good stuff.

I learned it from watching you.

I´m really looking forward on how you´ll cover the fuse. Until now I really appreciate your building technique and hope to learn from your work.

As of now I never constructed a plane from a three point view. If you could go in detail on how to design the single sheets for the "skin" (I assume you don´t cover it in whole, but cylinder per cylinder) it´ll help me a lot for further designs of my own!

I'm glad to see you're interested, Robin. I have a lot of respect for your patience and skill putting that Gee Bee together. I am solving problems as I go as this is my first design from scratch. I picked up a lot of what I used in the design process from nerdnic. I built his Bucker Bu 180 and really enjoy flying it. He also is working on a tutorial series on using 2d drawing software to design planes from 3 view drawings. He has some great tips and makes it look easy even though it really isn't. But it gave me enough confidence to try and keep trying until it comes out right.

Here are the links to the 2 parts of his series that are currently completed. I only saw part 1 before I started. I plan to watch part 2 soon.

nerdnic's How to Design DTFB Planes - Part 1, Part 2

You're right about addressing each cylinder individually. To have a smooth top, I plan to have a continuous top from behind the cowl to the cockpit but I will need to make precise cuts down the sides at the point of transition. I'm getting the shapes by wrapping each cylinder in standard white paper and marking the formers on the paper then cutting those lines.

I have the cowl and the front cylinder including the transition to the second cylinder figured out. I'm going to take a break and update my build log with text around the pics.

 

[JohnRambozo]

Ill take another look at my build and scratch my head and see if i want to change my sub fuselage to make it properly fit the former or just alter the tail taking out the aft former. Then ill start a thred and go from there some input never hurts. Its all about learning new techniques

Great! I'm looking forward to it. Its nice to have suggestions but the final decisions are always up to you. It can certainly help get past some trouble spots or even just make a decision when you're unsure where to go with it.

Updated text on first post.

Updated first post with Poster Board detailing.

Its coming along nicely johnrambozo looks great

Thanks, jayz. I just have to refine the poster shapes a bit and get some servos before I can maiden!

 

[jayz 84]

Johnrambozo what kinda of power setup are you using on this bird? She gonna need a good amount of power at 700gram. And gonna be a heavy lander

 

[nerdnic]

Ohh it's nearly done! You did a great job with the paster board. Let me know if you need any tips on turning the poster board into digital pieces.

 

[jayz 84]

Digital pieces nerdnic? Hows that done im planing on posterboard on my build

I'm gonna cover it in my video series but that's a ways away, so here is the quick version.

Make your pieces like John did, then lay them flat next to a former piece that's already in digital form. Take a photo as straight on as you can. Then take that photo and lay it over your plans in whatever program you're using. Now you can stretch the image and make it fit perfectly over the former piece. Once you've done that you can trace the poster board in your program and boom, scale, exact pieces.

It was kinda tricky at first when I was figuring it out because your camera distorts the image and streches it the further away from the optic center you go. I use this same technique with any 'free hand' piece I have to make. It works great!

 

[jayz 84]

Wow nice idea man ill keep this in mind

 

[JohnRambozo]

I'm planning to just try it with my Suppo 2217/7 1250kv motor and I have a ZTW Mantis 25A ESC coming in the mail that I'll be using to turn an APC 9x6E prop.

Its definitely going to be a heavy lander. Keep in mind I will also be adding the long range wings to the plans and testing those before I consider the design complete. Should be more floaty with those.

I'm think I may have to reduce the width of the ailerons on the racing wings, too. They take up about half of each wing. I'm going with very low throws on the maiden. haha.

Great tip! And I was going to just measure stuff.

That should get her around well, but ya with your racing wing shes gonna stall very soon so you will come in alittle hot so give her a long run way get her down to 20 30ft off the ground and i just cut power at 100to 200 ft away and bring her in level your spped and weight will all depend on how shell come in so trim her out and test your stalls, and ya i would reduce your ailerons size they dont take much at all with speed

I desided to go a new direction with my rarebear build. The way i built it i just had no room for anything really. And even with my short moded pod it dosent fit, the wing gets in the way sence it a center mounted engine and where the wing sits so im doing a diferent fuse and lowering the wing a half inch thats where i got to before changing my mind

Cool. I know the feeling. It sounds like you ran into a lot of the same problems I did. Its good to hear you have a direction again. Stay at it!

Thanks, man. I thought it was going to be a lot harder, but using printer paper to find the shapes worked out pretty well. You'll see more of the true shape when I glue it all down but I'm pretty happy with it so far. Just waiting on more servos, as usual.

This is looking really good so far. Can't wait to see it finished. You have all inspired me to continue designing aircraft as DreamWeaver RC. I've been working on a P47 based on this and Nick's recent Mig 3 build. thanks again guys!
