Queen BEE

It all started with little Baby BEE. Thread here: http://www.rcgroups.com/forums/showthread.php?t=2201665
This is bigger version of model. I had to redraw entire model (not just scale it up). I used Kolibri airfoil, which has already proved with good properties in small Kolibri glider. The model is built from lightweight plywood and balsa. The fuselage is made entirely of plywood thickness of 3mm, also 90% of wings, only tail is made out of balsa wood. The model has as less possible parts so that the construction of model is simple and so far big fun to build it. Model is my design, since I do not like to build models from other plans.

I will use motor, that is designed for multirotors, since I want to have low KV motor, that can spin 15-17" propeller. I ordered Turnigy Multistar 4830 420KV, propeller light electric wood 15x8" and 40A YEP ESC (clone of YGE ESC). My model will fly with 4S lipo pack 3000mAh or higher.
My plan is to put FPV gear on it.

Tail finished, fuselage almost. Still need to glue wing support (will after I finish wings).
So far all weights 929g, including servos, FPV camera with pan/tilt mechanism, RVOSD V5.1, Multiplex RX 16 pro receiver and motor with propeller.
Hoping to get below 2400g RTF

Wow interesting model, I love the honeycomb structure, is all this hand or CNC cut?

Could you let us know the wingspan/dimensions?

Looking forward to more progress, Ken

So far so good. I was expecting to more than 250g for one half of wing. So finished wings with plastic film cowering will be around 500g, my goal was to stay under 750g + 1100g for finished fuselage + batterys around 350-450g depending on used capacity.

Some progress today. It took me less than two days to finish half of wing.
Since model will be used for FPV, I glued tube for pitot tube and add extra rib. I wanted to have removable pitot tube, if I decide to use it on another plane and for easier repairs in case of crash.


Still have to sand leading and trailing edge, glue 4mm join tubes in front and back of airfoil.

SO far all weights 1391g including all wooden parts, receiver, ESC, motor, propeller, servos and RVOSD. Still missing covering film, landing gears, control rods and lipo pack. Hoping to get under 2250-2300g RTF model.

Yesterday finally connected and tested RVOSD 5.1 and test motor with 15x8" proppeler and only 3S lipo, since 6S had different type of connector. 4020RPM at 10,5V and 11,6A.
Today spend most of day to install all wires in to fuselage and left wing. At the end it was time to cover one half of wing with covering film.
