Ted has sent building details for his BumbleBee.
Below is a followup received a couple of months
after the piece first appeared on the web site.
Here is Teds answer to Dave:-
So pleased to hear from you!
My friend at PMFC, Ian Middlemiss gave me a
copy of your aeromodeller Bumblebee Shuttleworthi plan In June 2010 and I just
fell in love with it. ... I built mine exactly as per your plan in balsa
with 'boots' and 'antennae' but used a brushless motor set up as we are
not permitted IC engines at Peterborough Ferry Meadows. It flew ,
but unfortunately it would just screw right into the ground after about 5
metres and no matter what I did it was just too heavy a wing loading
to fly as a balsa electric/ lipo model.
My friend Dave Clarke at PMFC recognised your
plan and told me that he had also built your Bumblebee Shutleworthi
when it was first published in the Aeromodeller.magazine.
Dave used a TD. 20 motor and said that
it flew exceptionally well , so well in fact that it flew away into a dot and
he lost it!.
Ian Middlemiss at the club then sucessfully built
and flew your Bumble Bee design using depron in lieu of
Balsa using a GWS pager dc motor/lipo combination at out flying
Ian discovered that to enhance the flying stability
the model really needed two wing struts to keep the wing angles constant
otherwise air current flow would tend to bend the floppy depron
wings like aileron control surfaces.
I use two simple piano wire wing struts and
the model is now incredibly stable , easily flying a stiff
breeze out of doors on all versions.
-Behold three versions of your bumble bee...
A4 size voodoo 25motor 90 mA cell , Pboro 1
gram Fet timer 5x3 prop.
A3 size voodoo 25motor 90 mA cell ,
Pboro 1 gram Fet timer 5x3 prop.
A2 size £6.00 brushless ebay
motor 300Ma 7.4 VLipo 3gram Pboro fet timer 6x4 APC 'E'prop.
The A4 and A3 size fly beautifully both
indoors and outside , the brushless one really turns heads and I always tell
people where your Bumblebee shuttleworthi design originates from.
I intend to enter next year's Ebeneezer at
Old Warden with the brushless A2 size as it will qualify, having
the flat plate wings and no aerofoil . I have given copies of your
modified plan to dozens of people to date and I flew all
three versions at the BMFA Nats with great success to demonstrate
just how well you can fly with depron /electric / lipo
On another note, I also built your Space Shuttle from the
aeromodeller plan about 3 years ago in 6mm depron!
I however chose to make a more substantial tubular depron
body and used a brushless 2500kV pusher on 5x3 prop and 3 cell 640mA lipo
I terrorised everyone at the Ferry Meadows flying
field trying to get it to fly properly!
It flew very well once you got the CG right, I remember
you had the same trimming diificulties in your article but I eventually
got there and it was well worth it.
Many thanks Dave for your wonderful designs which
have brought us all so much enjoyment,
From Ian Middlemiss - Nov 2010
I am the perpetrator of the Bee revival.
Spotted your design in a 1994 Aeromodeller and could not resist it as it has no
section, no reflex , no stab and should not fly. My brushed GWS 12mm 7.4v
200mah LiPo Depron FF version climbs like a demon and is very stable, most
entertaining and bounces.
Thought you would like to see my RC version.....almost
complete. Note antenna and 6 legs but not wellingtons, alas.
10gm brushless motor from Robotbirds
6 x 3 GWS DD prop
300mah 2cell LiPo
3 x 3.5gm Blue Arrow servos
2.4 Ghz RX
Set up as rudder/elevator but twin servos on each
elevator half just in case I need to go to elevons. (Thought unlikely).
Will finish for trials in Spring 2011.
Thanks for a great design that should not fly.

After todays foray into the continuing adventures of
ancient house renovation, I'm now free for a while.
I just love the R/C Bee - any chance of the build/plan
details? After seeing your reincarnation (the original has gone to the
great hive in the sky) I have to admit that my interest is piqued and - with a
huge gymnasium to fly in - I can see a super-lightweight jobbie buzzing round
the lights. Not only that, but there's a 200Watt, 3750rpm/volt inrunner
just screaming (?) for an outdoor model, just laying there in my
atelier (= workshop - posh name for my old caravan that's been stripped
of internals) - waiting patiently.
I assume that my e-mail to Ted got copied to you so I'll
try not to overlap the blurb within.
Following the 'potted history' and the move to La Belle
France for many reasons, it didn't take long for the bug to bite - HARD!
Although I had built just a few models over the 'business' years before
2003, I had almost nothing but my old modelling kit, a small engine collection
(remnants of a much larger one) and a pile of odds and sods that could be
cobbled into something that would fly. The old truism; "You can take
the man away from modelling but modelling never leaves the man." is very
accurate - After 3 years of hard graft on the house I had to pull back a bit
and spend some 'me' time, as did my Wife Pat with her Patchwork, etc. She
needed some space of her own after working 'cheek by jowl' with me on some
extremely hard renovation work.
It was around this time (late 2006 ish) that I bought a
French model flying magazine, just out of general interest. I was
surprised to see that a specialist model builder was advertising his wares and
was based just 25km from my place. I contacted him to ask if there were
any clubs locally and was surprised to get - almost by return - an affirmative
reply and invite to visit the piste (piste - anywhere sports or similar are
performed) to meet the crew on the following Sunday.
I tracked down the area by his description and was
amazed at the site/sight - a full-sized 500 metre paved runway with run-off to
the 'pits' and - just across the access road - a grassed plain some 3/4 by 1
1/2 km. in size. It's not perfect, but very nearly so! The first
guy I met was a member setting up his electric trainer - Jean-Michel spoke
no English, I almost no French, but we managed. The guy that invited me -
Yann Dobignard - turned up later and introduced me to everyone else. None
of the cold-shoulder that I've been show at many places in England, these guys
are very friendly - it's a Breton thing.
It turns out that the runway and grassed area (parachute
drop zone) are part of the Military Training School of Coetquidan (spoken
Co-wet-kwi-dan), which also lets us use the large gymnasium. We also have
the use of a couple of lakes nearby for floatplanes. The club Patron
(boss) is Roger Nieto, International F4C flier for the French team a few times
- he's a Captain at the camp, hence the leverage to use it.
The past 4 years have been a bit of a rush, what with
continuing work on the house, doing work for other Anglaises and building my
stock of equipment and models. Despite a couple of bouts of muse
withdrawal, the models don't stop coming. I design, build old Ebay won
kits, renovate cheap purchases from others, etc. Anything in fact to keep
the interest alive and the hands working. The common theme is that they
have to be 'interesting' or different. On the drawing board this winter
is a De-Monge Monoplane and a Hurricane - but not the Hurricane of WW2 - this
one is much older. I have to re-wing the Pegna Rondine after substance
abuse and wall heater collision. The virgin HP-Sayers Monoplane is
trembling 'on the blocks' waiting for this weekend and its maiden
If the weather plays nicely on Sunday, so will I.
The Senior Telemaster I bought - complete with Super-Tigre .61 - for 50 Euros
awaits another sortie following its change of clothes, and an engine swap
to an old Profi .75. It flies like a motor-glider and is the nearest
thing to aerial Valium I've ever encountered. The French guys don't get
the joke of the logo on the side - do you? The little blue/white thingy
is a Bede BD5 I designed/built 3 years ago. It flys like a demented
dingbat on an ancient OS .10, but is now retired with terminal fuel soakage -
perhaps electrickery would have been better. The two others are (front) a
Livesey DL5 which - due to aileron insensitivity - flies only in very calm
conditions. The rear effort is a 'Baron' - I believe an old Belgian
design/kit of very many years ago. I bought the kit for almost
nothing on Ebay and it putters around with the draught (couldn't be called
thrust) from a 1960's Merco .35 - again, only on balmy days.
Other odds and sods litter the store room and await their
call. I wonder if you saw the photo/reference to the silver biplane -
it's a Corcoran 65-1 that I am currently trying to sort out. The
first two flights were clenched buttock affairs, as once over 30 metres
away and airborne it went apeshit, acting like a manic Galloping Ghost model
(are you old enough to remember them?) and almost out of control.
The problem was signal glitching from the 2 x ESC's to the 41MHz (French
standard) receiver. My mate Don Sim (now the second Anglais in our
throng) has given me a 'spare' basic spec. 2.4GHz Tx/Rx to try and conquer the
effect. My Wife - ever the critic - reckons that the plastic pilot looks
like a failed porn star... How would she know?
I think perhaps I'd better end there and await your reply,
comment or ribald retort.
Best regards, Dave Goodenough.
