Avidventurous added a topic in Avid Model C 7 Nov 2023

Hey guys. I apologize for asking something so obvious but I looked for quite some time and couldn't find it.
I"m looking for an Excel Sheet or table of plot points for a Stol wing WITH ribtails for the flaperons. A 1:1 drawing or template would help also. I"m pretty sure it's already in the forum somewhere but I can't find it.
THANKS

This probably isn't the proper forum for this post. If so, feel free to move it.
I thought you guys might be interested in an interesting quirk in hydrodynamics. I stumbled across this video on Utube. Please check out the first segment, although the rest of them are interesting also.

I haven't flown my gear yet, but the design is in this post on my thread. http://avidfoxflyers.com/index.php?/topic/7354-another-kitfox-iv-rebuild-project/&do=findComment&comment=68547
This is a thread on my ponderings about the gear and my design of it. http://avidfoxflyers.com/index.php?/topic/7688-fuselage-landing-loads-kitfox-iv-and-cabane-gear/
The landing gear is shown in this picture. FYI, I'm about ready to get the engine running again, and then small stuff before it flies again.

Here is some info on the gear. I do think he has modified his design somewhat though. As I recall, the tube between the cabane and the gear leg attaches lower down, near the end of the axel. JImChuk

Main gear technical drawings

Hi there, it seems that most of the modified gear welders are out of business now and none of them are located in Europe, so I am thinking of having a welder here to build me an extended gear for my Avid MKIV. Would any member of the forum be willing to share some technical drawings of an existing solution?

I definitely want to set it up as a tailwheel. There is going to be some detective work when I get it home. The current owner told me that the original owner had plans to remake the wings into speed wings and there are two sets of landing gear. I'm sure that other mysteries will turn up.

The Polini 303 engine that I tried to use was just too light for the CG. Just bought a rebuilt 503 to install. May be old tech, but still reliable as can be.

fantastic, I am excited to see/hear your cat in the air. Also I'd love to see your final W&B with the 582 engine fitted....see the difference with my 912 setup. Let me know if I can help you in any way for your 1st flight;)
P.s :phase 1 radius 500NM?

AvidJack added a post in a topic 912 uls radiator/fairing for IV speedster 10 Oct 2023

I picked up a 912 radiator, and started looking at the mods to the radiator speed fairing- it's a total rebuild. Which made me start figuring.. So, can anyone tell me why the cooling area of the vaunted 912 radiator is actually *smaller* by two square inches than the 582 radiator, which fits the speed fairing? And how that makes it better? Extra capacity by a few ounces in the side chambers can be cured, and I don't think the heat flow differential of two inches in height is going to make that much of a difference.
I had all the measurements for the "bigger" 912 radiator, but hadn't sized the "smaller" 582 radiator. Still spending time learning about radiators, thinking I may go the 582 route. Any thoughts? Anyone have experience with those 2-row ebay 582 radiators?
There's always sometHing.
Thanks, Jack

Good catch Chris on the trike gear in the tailwheel spot. Sharp eyes. JImChuk

Thanks! Yes the gear moves so easily from extended to retract it is amazing. I feel lucky that the idea to use a bungie came to me :-)
Regarding the battery, I don't know. I just took the fuse to the airport to put the wings on and I will do a W&B. and figure out if I need to move it or not. That's where it was. I'll move it if W&B says I should. Good call and thank you!
I have it all re wired and re plumbed, have run the engine so its pretty much ready to go. I just got an email from the FAA yesterday asking me what phase 1 fly-off radius I wanted! Can you imagine that? Since when do they ask? They have been wonderful to work with on this project.

ChrisBolkan added a post in a topic New here just bought an Avid 7 Oct 2023

Welcome! This is an incredibly helpful and knowledgeable group.
That looks like a nose wheel weldment in that fuselage. Worth it weight in gold IMHO. That means the plane can be easily converted between trike and TW configurations making it more saleable to a much broader audience.
One thing I notice is that the fuse appears to be sitting on trike gear positioned in the TW mounts. If you are planning to fly it as TW you will need the TW gear legs which are longer and swept forward.
But that and many other details are a long way from being important right now.
Congratulations on your new plane! Avids are awesome.

ChrisBolkan added a post in a topic SAVE the Ellipse! 7 Oct 2023

I almost bought an Ellipse! It was a beautiful plane. Could fly very fast and very slow. This was many years ago. It was an unfinished "kit" The wings came completed because they were so complex. Made of wood. Then common sense took over (for me anyway) when I realized just how difficult it would be to repair a wing if a ground loop or something damaged it. And I would be just the one that something like that because I like to fly and land lots of places that are sub optimal. I ended up passing on it but it was a GORGEOUS plane and would have been incredibly practical except for the complexity of the wing.

SAVE the Ellipse!

Ed at edshoe5272@gmail.com has a deal for you. For those who may not know, the Ellipse was Dean Wilson’s 4 place design, but only 5 or 6 were ever built, It was featured here several years ago, maybe someone can pull it up? BTW, Dean is still doing OK.

One is for a 582. The other one I am not certain what it was purchased for. It comes with an Arrow 500 engine that I am not sure if I am going to use. It is new old stock, but there isn't much information out there about it.
