|Thread: Christmas drones - how many, and where will they be flown?|
CAA and the Drone business are taking it seriously enough to put together regulations to ensure drone activity piloted or onboard systems are safe and secure to operate and for these to be in place in 2018. As costs of fuel for delivery vehicles rise, drone delivery will be seen as both cost effective and green.
my mistake but how many modellers fly above 400 ft or thereabouts other than gliders in thermals?
I recently attended a presentation on drones by a member of CAA and someone from the business side ( making and providing drone services such as surveying etc ) and they indicated the proliferation of drones of all sizes and capabilities is causing concern for the safe flying of drones and they hoped to have CAA regulations in place by 2018. The Amazon proposal for drone delivery was also mentioned and I came away with the impression that Amazon is making a play for all airspace below 400 ft which is the space we modellers are allowed.
googling for more info , I came across this link from the USA in which they target 200 to 400 ft airspace with hobbyists limited to flying in dedicated locations - out of town etc. This would rule out current legitimate RC flying in local parks/playing fields. Hopefully BMFA are onto the Amazon proposal.
i cant help feeling gloomy about it all
|Thread: Saito 100 suspect bearings|
I have a Japanes magnum 90 4 stroke which developed a lot of side play - so i changed the bearings and guess what - side play still there. came to conclusion i wasnt strict enough in keeping the large props balanced and this resulted in the front crankshaft bearing housing being opened up slightly. I should really have stripped the engine down and tried to shim the housing but as model and engine getting on a bit - I just fly as is.
|Thread: speed 600 motor with 2.8:1 gear replacement?|
thanks Pat - have redirected
ash - email in your inbox re replacing 600 motor
i have sent you an email re replacement
|Thread: Berkeley's Custom Privateer|
that looks like the finished privateer
I like the way you left the front planking to show just like the teak decks of yachts and the stringers on show at the back - real modelling.
has it flown yet - any air photos / videos?
Liked the video, | had to turn back and rerun the takeoff - it was so fast breaking free of the water.
Nice choice of model - will look in with interest on the build. Do you have a pond to fly it off or are you going to fly it off grass??
Like the magnet idea to hold the wing floats in.
the vintage forum of RCgroups have just started a build projects - soar or splash - glider or floatplane.
your build log duplicated there would be a very welcome addition on the forum
|Thread: Poly-C, Eze Kote or Ronseal Diamond Hard?|
Are any of them fuel proof against diesel or glo ?
getting close to finishing a cloud cruiser powered by a 4 stroke and need to decide how to cover
|Thread: 'Black' Friday modelling bargains|
thanksgiving is a major traditional american holiday following taking in the harvest
the day after has developed into the biggest sale day in the usa and the term black friday , I believe started there - not sure why but wiki indicates that it could refer to the traffic/pedestrian jams during the sales, but it could also refer to the day the retailers went into the black and started to show a profit - take your pick but i would assume both reasons apply over here

|Thread: All our yesterdays - our old pics|
photo from the 70's of my Envoy which has been resident somwhere in the New Forest for about 40 years. Flew away with a nice ED Bee up front. Free flight of course.
The other model is my Cessna Skylane from the Carl Goldberg kit. Nice free flight model but has been waiting patiently on the latest micro RC gear and brushless motor to take to the air again
|Thread: Castor oil - alternative to after run oil?|
a squirt of WD40 used to be the thing to do to prevent water attraction and laydown by the hydroscopic action of any unburnt methanol or water in the exhaust gases.
|Thread: Forum members' new models: Let's see them.|
My latest model is Ben Shereshaw's 1937 design, the Cumulus. 100" span and weighs in at 4 lbs 12 ozs. Covered in doped polyspan with red tissue trim. The 450 Watt motor takes it up not quite vertically. Photograph including me in it to show the size of the model
|Thread: planning permission|
bmfa provide help in dealing with the planners and putting in an application
watch the timing tho - our club lost our site perhaps because the supporting case from bmfa was a few days late
modelling is recognised as a sport and the councils have a duty to provide sporting facilities
|Thread: Ron Moulton Druin Turbulent Aeromodeller 1955|
re mega mamselle and aerial photography - been there and done that a long time ago.
chap turned up at field with small vhs video tape camera ( this was long before the modern miniture stuff available now.) He was looking for a model to trial the camera and my big mamselle fitted the bill.
camera was rubber banded onto top of centre of wing pointing slighly down over the nose.
When played back on the tape unit he had with him, the most striking thing was as the revs varied , the strobe effect would give variation between slow forwrd, static and slow back. The quality of the video looked good and he promised to send me a copy of the tape but unfortunately never did. If he is in on this forum, please could I have a copy
Nowadays, in addition to miniature recording cameras and telemetry, the use of brushless electric motors helps to cut out any engine vibration - fortunately our heath robin rubber banding dampened out the 4 stroke vibration.
Vic Smeed's Mamselle is a great design and the original 38" span free plan from the 50's is still listed in the X plans - here
the search only showed one mamselle but rcme published a 54" version for RC a few years ago and that should have showed up - suggest you look at all plans under £20 - its in there somewhere
The mamselle scales up nicely - I have built 3 off 72" span and a 108" span all with virtually no change to design or construction. Dont reduce the dihedral for the scale ups - it doesnt look right.
Why 3? The first was a lightweight built for RC training for ATC cadets - no buddy boxes then so needed a stable flier - in trouble? - throttle back and hands off and the Mamselle sorts herself out. 2nd one built for myself before the 108" version. 3rd build more recently as a successful test bed for covering with doped 100% polyester dress lining as a much cheaper alternative to solartex as my next build would have needed over £100 solartex to cover
the 108" span mamselle is over 25years old and still flying allbeit with a new covering - can be seen here on utube
**LINK** this video taken on vhs about 1990 and converted to dvd
The recovered verion can also be seen on Micks utube collection which if you are into vintage are all worth a look as well as providing some inspiration for your next ( first ) vintage build
the plan i have ( free plan from aeromodeller xmas ) has the number fsp 613 and states quite clearly its by ron moulton, so you are clear to go on that one
RCME plans service is not all that great at illustrating models - a poor show in this day and age when you can get photos from modellers easily and copy them into the plans servoce using modern digital aids.
Also there is no excuse for ditching plans ( or relegating them to a backwater such as x plans ) with all the modern draughting facilities available to keep masters of all plans and print as required - just look at the difference laser and cc cutting based on computer dwgs has made to number of kits now available
It is in the RCME X list and I include a link to there showing several turbulents. The one you want is fsp613 plan
It was on the back of the mamselle plan which I have but in very poor condition having been used several times
enjoy the build
