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

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.

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

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

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

**LINK**

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

Ian,

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

**LINK**

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

I store my models vertically with the nose up - keeps any goo out of the plug and also out of bearings as goo runs back into crankcase

Hello Rob,

The gear-puller looks perfect, it should work a treat!

When you use it expect one of two results; either the prop adapter will slip straight off without issue and you’ll wonder what all the fuss was about or it won’t budge! If it’s the latter, get some tension on the prop adopter with the puller and then heat the prop adopter with a heat gun; be prepared for a pop/crack/bang when it releases. If you don’t have a heat gun, just keep increasing the pressure, it will move (eventually) but again it will probably go with a pop/crack/bang when it comes off!

The trick here is after getting some tension then give the puller a sharp tap with a light hammer and the shock is usually enough to release the stick of the adapter

Thread: Laser cut parts. What about the black bits?
12/04/2014 08:53:08
Posted by Bucksboy on 12/04/2014 06:01:37:

I've built 3 models from the Brian Taylor range using laser cut parts, I don't do anything apart from dust them off by rubbing my finger over the edges. From examining crashed parts later the black bits have not affected the glues strength at all. I use cyno in the main and super aliphatic for some bits.

when laser cutting started, it was stated then that the charring would have no effect on gluing and I think this is particularly so with cyano and have had no problems with glue joints.

I lightly sand the sheet of parts before seperating them out just to get rid of loose carbon if any. I only sand edges where they show

I think I recall the use of Brasso as a very fine abrasive to reduce and polish pistons and contra pistons where these were tight.

If you are considering flying at any club sites or meetings, you may find that bmfa insurance is req'd

Thread: Light weight fillers
25/02/2014 08:58:35

A DIY lightweight filler called spackle is popular with modellers in the USA and before the advent of lightweights over here in UK, I brought some spackle home for modelling. Its non resin, I think and I only use it for gap filling as it has no strength to it. Dries quickly and sands easily

I crunch them home using the bolts then a drop of cyano at the spikes does the trick

I have seen and heard one on a vintage model - a majestic major if memory serves me well - a beautiful low purr as it whispered past.

Only a few were made and unlikely to be any more- shame

worth the £400 - dont know if I could stretch to the possible £1100

Maidening my twice sized Debutante by Vic Smeed. Video shows it on its second day out when there was light winds which showed of RC assisted vintage flying at its best. Hopefully the link will work
