Hi Chris,
you're quite correct,Litespan is said to be fuelproof,but we've found with both litespan and solartex they seem to get 'ingrained' with handling etc,and soon look grubby. Hey,but I suppose that would be an instant 'vintage' look.The fuselage in sprayed with 2-pack car enamel...................cheers,Mal

Right, let's see if I can post some more pics..............................
 
below is cowled engine,a Mills .75.......................
 

top cowl off, showing tinplate tank.............................

rest of cowl removed, rest of fuel tank....................

you can probably just about see the 4xaaa power supply attached to the lower engin bearer..............here's a better picture of it....................
 

and again............................................

hope that helps a little, I'll post some of the servo installation soon....................Mal

Hi Danny,
I'm going to try and post a couple of pictures of my 'Mam'selle', hopefully they will come out ok.My camera isn't impressing me that much,I might even have to splash out on a better one.........(poor workman etc etc)....................here goes...................

picture ,obviously ,of the wing,showing effect of fuel-proofed 'litespan............
 
 

 

Hmmmmmmmm, worked that time,I'll post some of the engine and servo installation in a short while..........................Mal

Hi,
yes it's definitely a Merlin 0.76cc. This is a standard Merlin,they also did a 'Super Merlin', which had red anodised cylinder finning,and a red anodised spinner .Apart from this anodising,it appeared to be identical to a standard Merlin. Later Merlins were fitted with an 'easystart' spring starter...........................Mal

Almost certain it will be a plan built 'Deacon',designed by the great Phil Smith,and kitted by Veron,powered by a Boddo Mills 1.3

Mal, am I right in assuming you have attached the tailplane etc already, and are going to cover them in situ? Doesn't that make it awkward?

Cheers
Danny
Hi Danny,
yes, you're quite right,I did attach the tailsurfaces before covering the model,and it did indeed make it a little awkward to cover.It did make it a bit easier to fair the fin into the fuselage,so it's a bit of a 'swings and roundabouts' situation.I think either way is correct,or possibly incorrect..................cheers,Mal.

Hi Danny,
thanks for the compliment.What I have done with the stringers on my model is to continue them right to the tailpost,they will all fit in,tho' it is a bit tight,but nothing to worry about.I notice you say you are going to trim the fuselage to allow a bit of down elevator.I have done mine slightly differently in that I have used a two-piece elevator,joined with a torque rod (posh name for a bit of wire),also I've glued the tail surfaces to the fuselage.Incidently,I meant to mention the other day that 'Litespan' does look like coloured Modelspan tissue,but only certain colours appear translucent.I think the colours are red,orange,yellow.I think all the other colours appear as 'solid' colours,also while it does shrink with heat,it shrinks nowhere near as much as Solarfilm or similar colours.Hope this is of some help to you,,,,,,,,,,,,,,cheers,Mal.

Hi all,
does anybody remember buying diesel fuel in a glass bottle,...............I think it may have been sold by 'E D', (electronic developments) to complement their range of engines................................Mal.
 
p.s. if I remember correctly,it cost about 3/6 (about 17 pence) a bottle in 1956-1957
Thread: Mam'selle.......
17/11/2011 11:56:04

Hi Danny,
hope I can help you a little with your 'Mams'elle'.I covered mine in Litespan,using Balsaloc as an adhesive.After covering,it is heat shrunk,carefully,as the heat softens the Balsaloc adhesive.I then sprayed a couple of coats of well-thinned clear dope onto the litespan,then colour trim in 2-pack paint,then finished the clear-doped sections,i.e. the wings,tailplane etc,with 2-pack clear ,as used by the car trade over metallic finishes.All this may not be nessarsary,as Litespan is claimed to be fuel-proof,but that's the way I did it.The (2) servos were fitted behind the ply former the holds the undercarriage,about level with the crutch,with the rx below them.For the rx power pack,I used a 4xaaa flat pack,strapped below the lower engine bearer,inside the engine cowl.I know that's not ideal,but the model was pretty tail-heavy by this stage.All-up weight is 14.9 oz,or 430 gm,I'm sure it could be made a little lighter with a simpler finish.So there it is,it may be a lesson what not to do,but it may be of some help to you.I'll post a couple of picture later,that's another hassle for me!.................cheers,Mal.

Not sure when the Mamselle was first published, might help to fulfil the model flying dress code if I knew, anybody know?
 
 
Hi Danny,
'mam'selle' was published as a free plan in 'aeromodeller' Christmas issue either 1956 or 1957,not quite sure which year,I built one from the plan while I was still at school,which was Merlin powered,just completed another,with a Boddo Mills 75 in........................cheers,Mal.

I really don't remember the "vibromatic" engine afore-mentioned.Tell me more!

The Frog 150 'Vibromatic' was a rear intake 1.5 cc diesel.The induction system consisted of a spring-loaded petal valve,which opened or closed according to crankcase pressure,in a similar manner to a reed valve.I never owned such an engine,but they seemed to get quite good 'write-ups' in the modelling press.I can confirm the merlin was a good little engine,in fact,I still have one in a Vic Smeed designed Ballerina,and I recently bought one,in a control-line model,for £8 at a car boot sale..................Mal

Hi Alan,
yes you're right,I too blew the picture up and could then see the flat in the prop-driver.Didn't see it earlier.So yes,it must be the shim washer ,or rather the lack of it,that's causing the problem..............................Mal.
29/08/2011 18:42:53
Hi again,
just checked an OS 46AX,and the crankshaft has two flat sections,the prop-driver ( the piece you are holding) should have two correspondig flats in the centre hole,which yours appears not to,and there is indeed a black washer fitted between the crankcase and the prop-driver.Hope this helps..........................Mal.
29/08/2011 18:34:00
That appears to be the wrong prop-driver for that engine.There seems to be a flat section on the crankshaft,and the prop-driver should have a corresponding 'D' shaped hole to fit.Not being familiar with your engine,I am judging this from the photograph.If this is the case,it would seem you have the wrong prop-driver for some reason....................Mal.

Hi Danny,
model's looking really good.In answer to the problem of the titebond 'rivets' sagging as they dry,I found (not my idea,btw) that pva white glue,mixed with talcum powder to a creamy consistancy,dried out very nicely when applied to the model via a syringe.Obviously it must not be mixed too thick,or it will be impossible to push through the syringe needle.On occasion,I have substituted the syringe needle for a piece of small-bore tube.As regards obtaining a grease-free surface prior to painting,the stuff I use is 'panel-wipe',which is available from auto-paint suppliers.Keep up the good work.............Mal.

Hi BB,
I would say that propo radio became affordable (just!) for the average modeller round about 1969-1970,when Futaba brought out their 'Digimax' outfit,which was sold with a complete set of crystals and frequency flags.Mind this was on 27 mgh,and there were only 6 frequencies.The colour codes were red,yellow,green,brown,blue,and orange.I can't remember now which colour was which frequency.This outfit,.iirc,was about £150 ,still a big chunk of cash in those days.I remember a couple of years earlier that a Kraft or Orbit radio,top stuff,was the same price as a new austin minivan.When I bought my Futaba,I couldn't afford 4 servos,so I bought it with three,and saved up for the other servo,which cost about £18.Don't forget,these were,by today's standards,very basic radios,no servo reversing,no mixing or expo etc.We used to have 2 servos that would travel one way on command,coloured red,and two,coloured black,that would travel in the opposite direction.However,despite the cost,I think a lot of modellers took to proportional via Futaba,although a few other reasonably priced makes came out,I think Futaba gained a head start,which,perhaps,they have never lost.....................Mal

Hi Erfolg,
I tend to agree with what you are saying,having said that,it was in the late '60's-early '70's when I thought I read it,so I could well be wrong.Don't forget,also,that Doug Spreng was a top-class flier,a one-time world aerobatic champ.I remember his model,the 'Twister',being published as a plan by 'Radio Modeller' magazine,with an article describing his aerodynamic thoughts,which the writer 'pylonius' promptly had a good-hearted amusing 'dig' at.Does anybody remember 'P'ylonius'. Who was it,and what happened to him? Doug Spreng,together with Harry Brooks,went on to form 'Sprengbrook' radio systems.....................Mal.

Hi Erflog,
I seem to recall reading ,a long time ago ,that Doug Spreng invented the feed-back potentiometer,which is the basis of a proportional servo.......................Mal
