A simplier KF version may be a good idea and a popular plane on this wide open forum. I would not be offended if someone wants to draw up a KF version of the Peregrine. My experience with the KF is that it would fly well and be a popular scratchbuild but probably not be as aerobatic as the full airfoil.

Great, thanks! The peregrine does look like a more complex build, but I guess that's why I asked. Thought it might be a fun challenge. I might try it with a KF, maybe you have an outline of the wing?

I had a lot of fun building the 42" version so I decided to go ahead and make a 58" one. The smaller one is easier to transport and can take the load of my camera ok, but it seems like the larger wingspan might make it easier to keep things steady, and it's closer to the size of a real eagle. I glues the wings together last night and it's big! It will be my biggest plane, but it make me smile to look at it so it will be cool.

I thought I would post this video too. I guess it's a bit off topic since it wasn't taken in the Eagle plane, but it's take with the camera that I will be using. Also, a bird did come up and check me out during flight. I didn't get him on camera as much as I wanted, but about half way through I did get a few quick shots. He circled back a few times and checked me out, I can't wait to get everything ironed out with the eagle and get video with it.

I just got the camera too. It's a VadoHD and only weighs 3.5 Oz. I had the original Vado, it's about the same size but the HD one has much better quality video. Hope you guys don't mind, I wont post another aerial video unless it's from my Eagle plane!

Wing attachment consensus?

Lee and everybody:
What are you using as the preferred method for easy-on easy-off method of attaching the wing to the body, other than rubber bands? Pictures if you have them would be helpful.
Thanks....arniep

I am using industrial strength Velcro. It holds good and lets you reposition the wing if needed.

I'm using the Industrial Strength Velcro from Walmart. It holds even with the loops and rolls.

I am not familiar with Zelcro. But on the Velcro, are you using anything other than its own 'stickum' to enhance its holding power?

Never heard of Zelcro...where have you been?

Yeah, it was a typo. I have had success with the glue that comes on it as long as you don't try to stick it on a painted surface, part the the industrial strength part is the glue. But it really depends on the surface you are trying to stick it to. In spots where I didn't get good adhesion I just put a dap of Gorilla glue in between and it's on for good.

Kline Fogleman, Is an airfoil developed by a couple of cats from Germany,
(I think) It is a stepped airfoil. There are several variations; this will enable you to do a search. jp
