Flying Genie on a Carpet (New NIGHT VIDEO post 212 08/01/2009


After flying Dennis' FFF "Genie on a Carpet", I had to have one myself. It's a "stretched PBF", twice as along as it is wide. I've made a few of the PBF's that have been posted on these threads, personally I prefer this one, for the way it handles and the shear novelty of it. Since the pictures I posted of Dennis' Genie got so many lookers, I thought I would post some pictures of my build. Not that it's all that hard to build, but it's just so much fun to fly. I'll list all the dimensions for anyone who might want to try one. I still need to paint my "carpet". I made mine 20" x 36" and used the following gear. Tower Pro 2410-09 motor, 20 Amp simple escape, 11x4.7 slofly prop, 1000mah 3s lipo, 2 HS-55 servos, GWS Rx.

Update: I am now using the FC 28-22 Brushless Outrunner 1200kv from HobbyKing along with a GWS 11.47 slow fly prop.

Here's the blow by blow of making the flying Genie. Cut a piece of FFF 20" x 36", then another 20" x 18". Glue the small piece on one of the bigger one, this stiffens the front half and adds some needed nose weight. Now cut 4 1/2" off the other end and then split it in half to make the elevons. Cut one of the long edges of each elevon at a 45 degree angle and reattach to the main board with tape hinges. Make sure you have a lot of throw in both directions, as slow flying and hovering will require it (see the pictures above). I taped coffee stir sticks together for the music wire pushrods.

I made a motor mount from a piece of plywood and attached it to the front with about 2 degrees right and 7 degrees of down thrust. Add a 13" piece of balsa for a stiffener on top front. I use a piece of scrap FFF from the fold area for a stiffener on the bottom center, it runs from the doubler to the back edge of the main board. Mount your motor, servos, pushrod wires, esc, Rx and battery.

Cut out and paint a Genie, or any other cartoon character 18" long and 13 1/2" tall. Glue it to the top of the boardfrom the back of the stiffener to the rear of the board. I mixed the elevons in my Futaba 8U radio. If you do not have a computer radio with elevon kixing, you can get an external mixer, such as GWS makes. The CG is at 9' from the front of the board, you can see where I mounted my gear to get it there. No additional weight was needed. I launch it underhanded, holding the front of the genie. If you build one, let us know how you like it.

Dave, nice Genie! How does a long skinny PBF compare in flight characteristics to a square PBF?

Jeff, the saying "flies like a trainer" is pretty much applicable to it. When we used to make them with slimmer engines, I let some of my "trainees" fly mine, they could control it very well. I'm not saying it would be a trainer for someone teaching themself to fly, but after a little stick time on a conventional trainer, they could do allright. It is more stable, I think, than the square PBF's, especially in slow high alfa. It will also fly inverted, do loops and a great barrel roll. I especially enjoy hovering it, if their is a little breeze, it's even possible to do a controlled verticle landing. I like trying to do elevon drags and tail touches, it has enough power to pull out vertically, at least until the battery gets low.

gpw, greta idea. Yes, fringe is definetly in order after I paint the "rug", I'll have to get a ball of yarn and make some.

Here is the "pilot" I drew for my carpet... I'm going to start construction today...I hope.

How critical are the dimensions for height...I guess I can blow him up as big as needed.

Later,

Dennis

Great looking pilot. The taller it is, the more drag you get, and that requires more up trim. 12-14" works best. Any other Questions are welcomed. Post pictures here and a flight report.
