I have been intrigued by homebuilt aircraft since I built the Zodiac. Next up, we'll do the Van's RV8, by request. Noah, let me know what specs you'd like. Otherwise, it's dealer's choice. (It could be, anyway.) It'll be a while before I can get it started.

There are quite a few of these at Flabob airport. I can't wait to dish out the CS's

Hi guys,
I would like the wingspan for the model to be around 60".
I also have a cs in mind but i have to take some pics.
Thanks,

Noah

Here's a start on the RV-8. This is modeled after an 80" build thread that I found. I used a separate cylinder to provide points for vertex locations of the main cowl.

Looking good. I just remembered a painting I saw of this plane, painted like an
ME-109, flying in formation with three different variants of ME-109s.
All were portraid in a ghostly blue hue.

The left one was alot easier than the right one.Funny how that is, but I always find that to be the case too. Same with the left half of a complex fuselage.

When I made the Extra, I came up with a really slick way to make the rear of the vstab flush with the rear of the fuselage. For the life of me, I can't remember how I did it. so now I have a new way.

I'm at 3,772 triangles right now.

jeffpn
02-27-2012, 07:11 PM
7,040 polies so far. Only the deck to do, and the servos.

jeffpn
02-28-2012, 05:35 PM
So I'm at work today, and it hits me! I thought of a brilliant way to add tautness to the wing covering. Sometimes, I amaze myself!!!

What do you think, Maj? Keeper, or no? And what about bones? Should we do them on this model?

abaser
02-28-2012, 05:39 PM
Wow! Where oh where did you come up with that idea? You are such an amazing modeler!:p

Man, I know the best way to get someone to lose interest in the forums! How many times has this happened now? I agree to build a model for somebody, and the requestor disappears!!! :eek:

No. Like the Albatross, it's a request. I haven't seen him, either!! I don't know why people ask for a model, and ditch us when we're building it. I'm doing a model for kmot next. Who wants to start planning his going away party? :p

Maj. Numbskully
02-29-2012, 09:31 PM
We need to start requiring a deposit :p:rolleyes:

:eek: Loving the wing technique...is it a big hit on polys?

jeffpn
02-29-2012, 09:32 PM
No, it's pretty reasonable. Should we do bones in this one, or just do a pre-bump with solid covering?

Maj. Numbskully
02-29-2012, 09:34 PM
I think in this case boneless chicken would be just fine

jeffpn
02-29-2012, 09:39 PM
Ok..

jeffpn
03-01-2012, 07:43 PM
None of my pictures show a tight covering, showing the ribs and spars, so I had to wing it.

Sometimes, I crack myself up!! :D

This doesn't have to be final. I am open to suggestions.

abaser
03-01-2012, 07:48 PM
Just my $.02, but it looks a little over stretched to me.

jeffpn
03-01-2012, 08:02 PM
How's this? By the way, the unbumped wing is 422 polies. The bumped wing is 1,508. I thought it'd be triple. I was a bit off.

abaser
03-01-2012, 08:08 PM
Better. Just for kicks, have you removed the hard edges to see how it looks? Wings seems to really show the ribs a lot more than Blender. I played around a bit the other night and Im a little torn on doing hard edges or not. Just wondered how it looked in wings with soft edges.

jeffpn
03-01-2012, 08:12 PM
No hard edges. Very subtle. I think I like it.

abaser
03-01-2012, 08:15 PM
Blender with and without.

What say ye? Im kinda linking the without myself. But with a little more indention in my case.

jeffpn
03-01-2012, 08:17 PM
Almost too subtle without. I'm sure Max will look different than Wings. I think I'll do it without multiple SGs, though.

abaser
03-01-2012, 08:28 PM
Here's a top to bottom comparison.

flexible
03-01-2012, 08:49 PM
The top looks more real for plastic film covering. However, if it were going to be painted, maybe the bottom, as the covering will be stuck to the top of each rib.

jeffpn
03-03-2012, 04:38 PM
Servos are installed. Poly count is at 18,071. I'm not conviced physically bumping the ribs in the 3D model like this is worth the polies. The same effect can be done in the CS.

Boof69
03-03-2012, 04:47 PM
Looks nice. Love the detail.

jeffpn
03-03-2012, 11:32 PM
Putting tautness in the wings, hstab, and vstab cost me 3,960 extra polies. Like I said, I'm not sure it's worth it. I'll leave it this time. It is easy to do, though. Maj., you can do it from now on!

abaser
03-03-2012, 11:46 PM
Wow! How about a wire frame pic? That seems like a lot more than I had figured.

jeffpn
03-03-2012, 11:58 PM
Here you go. The only edges I added were those edges necessary for the effect. Look at the wing before. Large faces, going across the wing. Adding the edges for each side of the ribs and the edges for between the ribs really multiplies the count. Like I said in an earler post - the raw wing is 422. The bumped wing is 1,508, more than triple.

a4magic
03-04-2012, 12:19 AM
Do you think you could put it over a dark blue background with spot light from the top? That is a nice looking plane!

jeffpn

Yeah... with bump mapping it never seems logical to do that. Less headache too. Looking great though.

jeffpn
03-10-2012, 06:38 PM
Here's what the modeled rib bumps look like in RF. You are right, WM. It's alot less headache to do it on the bump map. Effortless, if you ask me!! :p

It's an interesting process, but I really don't believe it's worth all of the polies to model them, when you can get the same effect with an _N map.

a4magic
03-10-2012, 06:40 PM
That looks beautiful. great job, now if I only had $150 for RF6....:p

You only need $50, if you have G3 or better.

jeffpn
03-11-2012, 08:54 AM
Here's preliminary physics. The rudder is way to effective, in my opinion. Also, I noticed flying in chase view that the model, when flying otherwise straight and level, will yaw (or bank, I don't know) slightly to the left, then to the right, and back. Does anyone know what can be causing this? I'm not a big fan of physics. Someday when the Maj. gets mad at me, all my posted models will be green, and fly like bricks. :D

Reminds me of Dutch Roll but it is hard to tell exactly what is going on, even in chase mode. What is confusing though is this airplane has only one of the characteristics that tend to cause it, so perhaps that isn't what is going on (large dihedral, swept wings, high wings). And further, when I experimented by removing the dihedral, it still happened.

http://en.wikipedia.org/wiki/Dutch_Roll

Anyway, that probably isn't it, but some related dynamic stability situation. It is pretty cool that RF6 can actually model these occurring.

jeffpn
03-11-2012, 05:28 PM
Well, if it's accurate, it's accurate. I have no idea. It'd be interesting to hear from someone who has an 80" RV-8. Naturally, I don't expect that. I asked a question at Flying giants in a thread about this specific model, and got no response. I wuldn't expect to find anyone here who has that plane.

Very nice Jeff, it looks like your mapping (I guess) allowed the Maj. to do diff. CSs` on the top and bottom of the wing, without the usual bleed thru from the bottom to the top of the wing, (as I have experienced in the past). Future CS`ers will love that:D

uncle twist

uncle twist
04-07-2012, 09:38 PM
Maj., i would be referring to the "LEADING edges of the ailerons" and the back side of the wing, where they meet, often when I`ve done a CS, those two areas are competing for the same color because of mapping, thus making it hard to do a CS where the colors are diff. from the top of the wing,to bottom of the wing. Usually the color from the bottom of the wing comes through to the top in that particular area.It would seem to me, looking at those pics, that somehow, between you and Jeff , that, that problem does not exist on this plane, thus making a future CS that much easier, should the CS be different from the top and bottom of the wing, smell what I`m steppin` in. I`m just saying, it looks great for future CS`ers:D in that respect. See what I had to do to FW-190 to keep the color from bleeding to the top of the wing

04-07-2012, 11:03 PM
Jeff, if your`e referring to the grey in my pics @ the hinge lines,then, yes, this is what I had to do to the bottom of this plane, to keep the red &white from being visible on the TOP of the surfaces.
Maj...............I`m complementing both of you on a job well done,in,what I see as a complicated area of an EA for future CS`ers. Don`t make me put a sucker in my mouth, and say,'Who loves ya baby"
"CRIPES` ALL MIGHTY". Then I`d have to shave my head. :eek::eek::D

That middle render is awesome for sure. Although try lowering the level of reflectivity of the floor texture for a polished floor look. That is unless a perfect mirror is what you were going for. Are these renders being done in max?
