Nice Bird!!! What wheels are those? No pics of the interior? looks minimal, very nice!!! how much dos it weigh?

Nice Marty, thank you for updating us. I don´t have my main computer running so I can verify, but from memory a built wood spar with metal ribs for a j3 was ~72lbs uncovered.

Keep in mind that Android has a high level of fragmentation*, some of these apps may not be compatible in your device.... (*disclosure I own Apple Stock :wink: and I am typing from a iOS device.) ...

Sorry I misread the add :wink:

It comes with the hanger!!!

Cool info, I´m still waiting for the graphine capacitors based batteries, same juice, 10K + cycles at under a pound and no risk of fires at all. :P price could be an issues at first.
At that wight,...

Thanks John, here is the result of the paper...

What CFD is that? Do you have the polars to compare it? I agree that computer models are just that models, but Xfoil has dad a pretty good reputation for laminar flow, it does not give you data on...

This data is all coming form Xfoils. Yes laminar flow does continue much longer on the Riblett vs the 35B (Mod or not) and it might be a better airfoil for slots.
:Geureka:

I guess we can call this demystifying the Riblett Airfoil.

So, what is the difference between all these airfoils anyways? Is there a magic Airfoil that can land you ever so slow, yet get you...

Missed you post Larry, Yes, I have my plans. Had them since late las year... sorry :(

So anyone flown the PA-11 with 65hp, how does one handle? Or do you need to consider moving to an 0-200 or O-23x for 100hp? What is fuel consumption like on the 65hp? Anyone runing P-Mapgs on the A65...

Here is a comparison of the Wag Aero 2+2 vs the data from JimC and myself. Jim's is in blue and the ordinates come from the image above, I took the 35B data and added 4% to that and is in yellow.

Cool Marty, I am sure there is a ton of people looking to see what those wings weigh... :D

Hello Marty, thank you for the feedback. The only trouble I have is the cheaper part of the equation from where I am sitting :D. Unless you can start a small side deal sourcing out spruce for those...

Hi John,


I am not sure it it will be cheaper or lighter :D but it will be the same strength, or else, it will not be a Cub wing... :)

As for the second option, and there are many...

It´s wood! and maybe CF... :D

Hi all,

Getting back to light wings. I was working over the weekend on a design (at least doing the calculations for it since my Windows machine died on me) where I'm thinking of creating a one...

Cool, got it!!! What I sis when I drew it up was make ordinates according to the 104%, so I took the 35B airfoil and added the 104% to that, which is what should have been intended (I believed) and I...

Hi Jim, are you referring to a station between station 44.100 and 50.40? I am not following the station you are referring to? changing 4.036 to 5.036 or vise versa only affects upper camber profile...

Roger, plane looks fantastic!!! the covering looks great, although there is that transparency some mentioned about the covering, but that does not bother me one bit.

My point exactly, there was debate, but when I took measurements the discrepancies where all over the map, thus the conclusion that moving from jig to jig changed some of the ribs in less than 2% of...

Hi JimC, By cord thickens I was referring to camber thickness on the airfoil. 10740
To answer your question, yes there are differences hence my questioning if the j3 and the 12/14 weren't...

John, missed your post, looking for that quote now. Thank you!

If it weren't for the fact that I have two J3 cub ribs and a 12 and 14 rib, I would have never considered this, however the two j3...

Jim, thank you, that does make alot of cense to me now!

Regards,

JM
