Hello everybody I guess it's my 1st real post here. I don't really have pictures of the build but it was a Brodak kit, I liked that the ribs had a pair of 5/16 holes in each rib to aid in construction, I used two aluminum tubes with all the ribs slid on to the tubes, it really made the wing go together nice. After the build got to the C/G stage I quickly  realized it was going to be real nose heavy. So I gave it a beak reduction and engine setback. This left no room for a hard tank like I had in mind behind the TeeDee. So I went with a externally mounted bladder.

Plastic P clips that I modified to hold the bladder to the fuse, that allow quick bladder changes with no tools.

I like the pivot style landing gear design that allows movement that is limited by rubber band if you have a hard landingFirst Baby Ringmaster build 16735713

Even after the radical engine setback and nose reduction to the fuse, it still needed tailweight!First Baby Ringmaster build 16735714

Awesome set up thanks for sharing. It's going to be speedy fun. Inspired by how you set your pressure bladder up. I like it! Also looks lkke your using the aluminum venturi body. Epic that will make it so much more reliable. Happy New Year Small Cox Logo This Site Rocks!

Nice clean build Michpatriot . It is nice to see some new construction here . I love seeing all these Cox engines but they need planes , cars ,and boats with them. Keep us posted as to how it flies .

Thanks guys, I'm thinking of building a Willie Nillie Ringmaster kit next and will run a radial mount just to see..I've got a couple ManWin wing trainers going together next for my girls to practice with (and me!)
Kind of thinking of a Babe Bee for starters but got talked into a Venom a couple weeks ago..now I'm having second thoughts on running it on the ManWin trainer..I think ill have to get a Babe Bee to train the girls with..just not sure about it when it comes to simple loops, will the Babe bee need tank pickup work to keep the juice flowing?

Looks totally badass..!!

No need to build a canopy...the bladder will look like a canopy when it's loaded... Cool
