Queen Bee (oz5764)
About this Plan
Queen Bee. Radio control model. Wingspan 48 in.
Quote: "A 48in radio control model by P Grimwade. Queen Bee was designed for the ED Bee and built around the Dews Radio Unit, so that the average builder can build a cheap but efficient R/C model. Two of these models were built to give it a thorough testing, and the weight of each one came to about 1 lb 10 oz.
Fuselage: The two fuselage sides are built flat on the plan in the usual way, the top longerons being cut off just behind F.4. While the sides are drying, cut out the formers F.1 to F.5. When the sides are dry remove from plan and glue formers F.1-17.4, and engine bearers in place. The rear ends of the bottom longerons can now be cemented together and F.5 fixed in place, after which the lower spacers can be added. The next thing to do is to pack up the front of the fuselage, and add the top longeron and the two struts which form the 'V'. When the longeron is dry, the uprights can be added. The tail platform can new be cemented in place, the blocks added at the front and the whole platform sanded to shape. U/C blocks should now be added, together with cowling and all other sheeting as shown on plan. When dry the whole fuselage can be sanded lightly and the cowling shaped.
Wings and Tailplane: The wings and tailplane are built fiat on the plan in tlic usual way, and call for no comment except at centre section of wings (see sketch).
Fin: Usual construction, but for rudder which is hinged by means of IS s.w.g. wire bound to rudder and het into 18 s,w..g, brass tubing at top and bottom of fin. Cement fin to tailpiece.
Undercarriage: This is constructed from 14 s.w.g piano wire and a in. balsa. fairing.
Covering: Original models were bamboo tissue covered, the wings and tail unit being yellow, and the fuselage and rudder black. Doping Fuselage: Two coats of clear dope. Two coats of banana oil. Doping Wings: Two coats of clear dope. Tail Surfaces: One coat of clear dope.
Flying: Check up balance to see that the CG is in correct place, as shown on plan, and check wing and tailplane alignment and incidence, wings 3°, tailplane 0°. Check glide once or twice and then switch on batteries and test for move-ment. For first flight give an engine run of 24-30 secs. Only give a few signals for the first few flights and then increase engine run and signals accordingly. The tank used was the one supplied with engine and gives a run of approx 4 mins. Keep all couplings and movements as free and as simple as possible.
Radio Installation. The installation of receiver, relay and actuator can be clearly seen from diagrams. The relay and actuator used were the ones manufactured by ECC."

Previous scan version.
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsThis was my design in 1950, following 2 years of construction.

I am interested in seeing the updated plans of my original design.

Good Afternoon Outerzone, I recently sent off a couple of these photographs to Mike Goulette (email@example.com) to see if anyone in SAM could identify the design, and he put them into an article with the photos - lo and behold a gentleman had read the article and identified my model as a Queen Bee designed by Peter Grimwade for Aeromodeller in May 1950 issue and now published by Outerzone. There was a plea for photos, so here you go. Use or abuse them any way you please [model pic and morepics 003-005]. I just wish I knew who built it - I know I didn't - but perhaps the builder will see the photos and come forward. A great little model and with my trusty FROG 100 it rises from the ground just as the name says - FROG = Flies Right Off Ground. My thanks to Mr A N Croft for identifying the model which was designed as a low cost intro to R/C. My model was powered originally by a Clan .9cc engine but would barely get off the ground and that was with two very small lightweight servos, whereas now powered by a FROG 100 red head it positively jumps into the air. I'm guessing the prototype powered by an ED Bee would come somewhere in between those two on performance.

Hi, Photos of Queen Bee from Cechia... Motor is Junior 2cc MVVS.

Great photos, of a very fine model. Many thanks.

What stunning photos! I built a Queen bee 25 years ago, single channel powered by an ED bee, and seeing those photographs I've decided to build another with an ED BEE mk 2.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
