I like it!

Jiminy!! Thats got fun written all over it.
The cute canine and birds loved it too.
Thanks Kim.

jiminy-

Does single channel mean you only have servo control over one control surface? Would that be rudder or ailerons? You can obviously turn left and right. Is altitude a preset trim on the elevator... but no, you need elevator to land. I'm confused.

Single channel flying involves a little more care in trim and balance.  The airplane is set to gently climb under power in level flight.  A gentle rudder input produces a gentle, turning climb...a harder input brings the plane around in a level turn or descending spiral.  Going back to level, the resulting upward "zoom" is checked by ANOTHER quick jab of rudder which helps kill it's momentum.  You can effectively control it's altitude this way.

You try for a fairly flat glide after the engine dies, and if your timing it good enough, and the field is BIG enough, you can even pull off a landing flair by entering a gentle turn, and going back to level as the plane is about to touch.   Takes practice and familiarity with the plane to do it!

I made the wing rails a bit longer to allow sliding them forward or back in the manner of our old balsa gliders, then made marks with a sharpie to help me relocate the spots I wanted: flatter glide for a little wind, and steeper for windless days.

Here are some others

Nice landing.

My pulse command system i had , the rudder flapped back and forth with input to the right the plane was suppose to go at a up incline and left was DOWN!! it did have a lift at forward motion .. Harder to control than you would think! Of coarse i was like 10Yrs, old Soooooooo.... I think if i have the money this year at the swap meet i may get me a Pod Power Bird if i can find what i want Eric

Hope you're able to find one! I've loved these things almost from the beginning. My very first shot at R/C was with an escapement-controlled Sterling Minnie Mambo...that I actually got to fly. Of course, it occasionally decided to ignore me and my desperate button pushing, and take off on it's own adventure!

Just try explaining a rubberband-powered flite pack to someone who's never messed with one!

I've still got it, and intend to set it up as a demonstrator to try and shame these youngsters with their easy lives of 'plug & play' !

I've also got an old Ace Pulse Commander System that works just enough to aggravate me. Want to get it going and actually fly it...another back-burner project.

Cool videos Kim! That Blunderbus replica is neat. It looks similar to an old design called "The Real Thing"
