ROY DAVIES 1

I must ask the stupid question, Where was the plan sourced from. Was it a freebee in the mag' or bought? If from the mag I may still have the copy. The itch is too big to scratch, but it will be a diesel assist I'm afraid. Or will it Hmmm!

There's always transparent film to sort that out. Looks a beaut. Lovely build

John, A similar problem can be caused by a small - very small, globule of water rolling around in the bottom of your tank or close to any other orifice. When you accelerate the motor the globule with roll to the opening and block it as it's surface tension is so great it prevents it breaking into smaller globules to travel up the tube/ jet. Check for a tiny cut in the tank pick up tube and the tube from tank to motor. It can be too tight to leak but big enough for air to be sucked up.

CHEAP LIGHTWEIGHT FILLER SOURCE Cliff I notice you have used lightweight filler which most of us do. I have discovered a source which is a 600gramme tub for £3 odd in 'Wilkos' I always check filler when I see it and I was chuffed when I picked the tub up and it weighed practically nothing. It is identical in every way, smell, texture and application method.

Sorry Simon, I have just noticed your posting with a similar train of thought It looks like it popped up while was typing mine Look at the time, date bar Roy

Nice model Colin, Don't run the motor too hot or the exhausts will shrink ! Re, Shaft breakage it is very difficult to get the hardness just right as the cross section is so small. You will notice this on small sized Allen keys they either work okay or go 'ping' first time you use them or end up like barley sugar. There is a bit of shaft overhang visible and 'a great deal 'up front' In the event of a slight movement of the motor backplate or spinner and prop or a bit of cogging on throttle up the whole lot could start to precess which would be the beginning of the end

Why have they got to be 3003s ? There are plenty of good reliable servos of similar power / spec etc. Just remember most of these so called copies have a one chip and surface mount technology board the old originals have multiple component boards. I have loads of Malaysia and china made servos and I have faith in them. You must remember the manufacturers aren't going to do a runner they want your return trade. Where do the UK sellers get them from then? What about the kits then, There was some proper rubbish made and sold in the UK way back and servos ? £12 to £16 for a kit with 22 or so components to build in. We are in a modellers heaven all we need is more spending money.

A lovely build by all concerned and very tempting as I have lots of wood eager and waiting to be used. I have a Guapo plan and a Lazy Bee Epp model so I like the shape and style. I would like porthole and lights with free pivoted cardboard 'passenger cut out to make it into a true fun /sports model on mine. Hmmm!

They are a bit on the heavy side and the spares, e.g. filters make your wallet weep. We still have ours 10 years on it gets less powerful as the months go on it can just about keep a pathway through the build up of dust due to its diminishing power. May not even be able to suck up a gossamer thin Balsa shaving up now I'm afraid to try. Don't believe that drivel It still works okay been retired to be 'bedroom vacuum cleaner' Less stressful for it.

Brian, I remember years ago buying a brand new in the box Hard valve Rx for 10/- bob at one of the shows as I still had escapments lying around. I didn't use and sold it on eBay a couple of years ago. 'Brimar' valve I think - I remember looking at a Blue Steel in Cosford years ago and it had Brimar valves in it ! I know the son of the originator of the Elmic brand of actuators and he says he still has a fair quantity left at his home. His name is Mike Elmes hence the name ELMIC. As Michael Caine said, 'Not many people know that'.

It's an art they have perfected and they get paid for it too, just like actors who only have to go through the motions and produce nothing except, words.

It is a bit sad to see what was such a vibrant place a former airfield was in it's hey day I went to Little Rissington when the Nat's was there all those years ago, it was not as I remember it. Same thing when I google Khormakser in Aden and others. They are gone but the memories remain - as they were then.

Just remember crimping tools are calibrated to ensure the correct force is applied to the cable and the crimper jaws have to be the correct ones for the gauge of cable being worked on. I have soldered 200 amp cables into terminals because that is the way they were made up. Worth noting is the tendency of the copper conductor connections to loose up over the years due in part to (in my estimation) expansion and contraction due to low level heating during current flow and med frequency, 50 cps vibration in the cables. I have had to remove my switches and sockets a few times over the years through mods and decoration and nearly always found the screws backed off a tiny amount which of course can cause heating up of the termination point.

I'm sure I read they're limiting the wattage to 1400. Which means you'll vacuum longer to clean to your homes standards or allow the dust to grow all around you. Better get my attic modelling empire done as soon as poss' with my 2000 watt job before they come and take it away. Maybe I wont loose as many screws with a 1400 watt cleaner (modelling ones)

Just spotted your C of G mod for the 'mate' I have covered the Seat of mine with industrial (aviation) flooring as the ply went black after I varnished it and it got wet. Cleans up easier too. Thanks.

Belly landing a Corsair presents another problem. The cranked wing raises the fuselage some way off the ground and the greatest mass of weight is there also. This will have the effect of projecting the fuselage up and over and whacking the fin on the ground while landing at even a reasonable speed. If you can land on really 'willowy' hay or grass there should be no problem. We have a large patch of rushes on our field and they are a godsend for arrivals that otherwise would be a disaster.

It's the 'I wanna Fly a Spitfire and a Lancaster' thing again. Good advice chaps. It is great to have the fever but it must be controlled or we lose a modeller through despair of the hobby. Good luck Michael and Jamie. Enjoy the future.

Yes Brian it had a valve, It was very well made as all OS stuff was and still is. Grey upper case with the valve sticking out and the tuning screws adjacent black plastic bottom, you had to make up the hooks to hang the suspension bands on. I remember we didn't have 'foamy' sponge as we know it, there was 'Dunlopillo' latex derived and hard black foam which was aircraft parts packing and 'horsehair' and latex shock absorbent material which was difficult to use. I remember the furious rewinding of the escapement rubber after the engine starts had vibrated the actuator and run it down. In the mid 60s I did get the better of single channel esc's using solid state receivers and a Gem controller and various actuators such as the Bonner compound and Emic escapement. I even had a Min X RX, and doing slope soaring with converted power models. Great unreliable fun.

A beautiful job Lee a credit to all your hard work. Have a safe flight and a three pointer at the end of it.

I have a battered rekitted/rebuilt Graupner Easy Star and it will out fly my Radian Pro which was a bit of a pig with its old fuselage. New fuse reinforced with rods in the rear fuse and the finpost plus going to a direct elevator servo, 'T' tail and moving the C of G back to 70mm has made it a bit better, more work to do yet to make it behave properly. The easy star has a hot motor and with go vertical and roll all the way up if I want it to and it just sits up there smooching about.

Hi Peter, I picked up a really old Black Magic with a Challenger 4 channel radio in it's styro box, on looking at the little listing pics I spotted something strange buried in the styro' so I bid and won it for £36, collect. I sold the radio £24, it was in good nick, Someone local to me bought the model or £30 The buried objects in the styro happened to be a 2 volt start battery and a glow clip. But best of all a 1947 Mills 1.3 dirty but as new and a1947 ED penny slot. Both engines were hardly run I got £80 for the Mills and still have the ED. There are plenty of bargains on eBay if you keep looking and using your senses

Spotted plenty of brand new OPSs for sale on a boat site

Brian, my OS single channel Minitron was a single valve but that's where the similarity ends. I was mounted on bands in a Mercury Aeronca ? with a ridiculous number of batteries that lasted all of 10 minutes in the hot sun of Aden. I never got anywhere with it other than a chattering relay and the rare 'click cluck' of the escapement. I boxed it and sold it years later. now I have an Rx in every model and there are quite a few - where did they all come from. I have more models than shirts and I have a LOT of shirts.

The Staines deep stall accident comes to mind. But I was at Farnborough when the Buffalo crashed and was standing just downwind of the crash spot. The aircraft did a descending spiral to the right at about a 30 deg' angle as he turned to square up with runway his rudder as well as his elevator were waving about like flags (in fact the whole fin post assembly was shaking in the turbulence generated by the top of the wing), to no effect so he could not effect a flair and plonked it on the tarmac with bits flying every where. 'So the rudder don't work either if it aint in a draft' I worked for a company that weighed/s most of these and it was quite a critical set up to make sure the longitudinal level was spot on as the moment arms are so long. There is a plumb bob point above the rear st'b'd door frame and cill.

Galloping Ghost, I remember seeing the great Pete Waters at his club with a Min-X galloping ghost set flying a Cassut type model of around 30" span. I think it was flying him and he was more than capable with most set ups. My friend 'tried' a fleet version later on just at the advent of proportional radio. It didn't last In those far off days when I had the RCM&E set I owned one receiver and 3 servos. We would slope fly in the morning, home for dinner charge the batteries 'Deacs' swop out the gear and fly power in the afternoon. Three different servos ! repair for the rest of the week as most stuff was not too reliable or strong then.
