Sky Babe foamie... now with video and plans.

Here are some pics of my Sky Babe, loosely based on the Stits Sky Baby plane. I made some changes, both cosmetic and areodynamic, but its a nice design basically. The changes I made are done so this plane might be able to be made into a J3 Baby Cub as well (which is another project for another day).

Edit: The video is on page 5, post 61. Plans are in my blog.

Oh NO... another great design. My build list just got bigger. I don't know what it is about bipes, but I loveum. I have the hiperbipe on my list too. Will Be interested how this turns out. I'll be watching

I remember seeing a small electric r/c Sky Baby flying around some dudes legs, and was simply amazed and blown away! I was very intrigued by this plane, but didn't know what it was. I came across it yesterday by accident, and decided to build one. I seen the vid at Youtube, too. It flies well.

Looks good Rusty.... but I think I would slim the fus down a little, maybe a 1/4"...It might help reduce the built in headwind a little.Lol

This maybe of interest Its a full size of X-Twin bipe

Rust, Cute bipe !!!! Looks a touch roll sensitive ...a small bit of dihedral and reduced throws might help...

Guys, thanks for the comments, and interest.
GPW... I did add dehedral on both wings, and intend to have reduced throws as well. Its pretty much a requirement on some "cartoonish" planes.
dekan... I can easily reduce the fuselage width as well, as this is only a prototype. Currently, its 3.5 inches wide.
Plans can be posted as well, but I want to make sure it can fly well first.

Very nice Rusty...

Did you simply work from a 3 view? or are the plans hand-drawn?

Rusty.....Sometime ago I built several small indoor free flight cartoon scale planes.
They flew ok at a reasonably high speed,but they tended to fall out of the sky at a slower speed.

I put this down to the amount of drag that was produced by the fus just overcoming the lift from the small wings.

Slimming the fus down helped to improve things

dekan... over the last few years worth of making cartoon planes I too have noticed they drop from the sky worse then lead bricks, so extra speed is indeed needed when landing, and general flying too. Narrowing the fuselage will help. I'll continue with this prototype, but alter the plans for a narrower fuselage (keeping fingers crossed).
My last cartoon effort was a Baby DR-1 (smaller then the Blue one in my blog, plans not available yet, but soon), which tended to rock on it's roll axis due to very short wings, and no ailerons. This one will probably do the same, but hopefully the duel aileron set-up will help.
A few changes I made: KF type airfoil on both wings, lengthening the wings a few inches, and also lengthening the fuse a few inches, too.
I don't know where the actual CG is supposed to be on the Sky Baby, so if anyone can offer this info, I'd appreciate it. Otherwise, I'll make an educated guess, and have at it. I come pretty close though. Thanks.
BTW I don't have plans for the Stits Sky Baby, just some pics from the internet, and another builder's build log pics. Any help is appreciated.
