QueenBee: 100" EPP wing build & fly thread
Thanks Ming!
The QueenBee core and the Bee cores arrived today, the new middlesection is from ONE piece of molded EPP: Looks pretty sturdy  The kit is not ready yet but Ming agreed to send me the molded EPP parts and some strapping tape... Now it's time to go to the kiteshop for carbon tubes  Peter |

Ming has developed a process for molding EPP, like the Elapor molded twinjets but then with real bouncy EPP
Found 4 en 6 mm carbonrods that slide tightly in each other and a 8mm rod as spar for the middlesection... Hope to have time next thursday for building, need some servo's too. The middle section has premolded places for a standard servo just like the outer (EleBee) wingpanels You can contact sales@windrider.com.hk for the wingcores, the kit is NOT ready yet... The outlines of the QueenBee are very similar to the Horten III, thinking of a nice freescale project later on Peter |

Here's a pic of the bottom of the middlesection, you can see the pre-molded holes for servo's battery and other equipment...

Used the hot knife to make the holes for the spars..
In the middle an 8 mm spar against wingflapping In the outer wingpanels 4 mm rods that slide into the 6 mm rods on both sides of the middle section... Weight of all carbon rods: 42 grams Middle section: 309 grams Two wingpanels: 96 grams Makes 447 grams so far without glue and things to come.... They say EPP is heavier then styropor but I'm happy with these figures for an 100 inch wing Peter |

Hi William,
The batteryhole is 18x6.5x2cm, quite easy to make it bigger though, my 10 cells CP 1700 pack is a tight fit with room on it's side... Will mix a few drops of water with polyurethane glue and let it dry overnight, lightest glue and fills up good I'm not going one piece. I will put some oil on the place where the wings meet and the 4mm rod goes into the 6mm one so the glue will keep that spot free. I will have then wingpanels with two 4 mm rods sticking out that sleeves into the middlesection 6mm rods.... Peter |

Ordered an Aeronaut 12x9 folding prop from www.aircraft-world.com
This prop will give 1500 grams thrust and a 90 km/h pitchspeed with the Axi 2820/12 on 10 cells (1900 gr. with 12 cells )Figures found on: www.flyingmodels.org Think the flying weight will be around 2000 grams so that will be enough.... Peter |

Take a look at this 1943 Horten IIIe, shape is very similar to the Queen Bee

I have to correct myself on one thing:
Ming told me the 85" QueenBee prototype was flown with elevons and flaps/airbrakes, the hundred inch version is still so new that even the CG is not known yet... So all the pics on www.windrider.com.hk are of a 85" QueenBee, this one is even bigger Decided to go the elevon/flaps route too, this big wing will be less then 2000 grams, so it will float forever: Think I need the flaps for a proper landing Peter |
