Hi Eric

I had happen to one of mine it turned out to be a faulty lead, it had a break, if you have another lead you could try it might be worth doing that if just to rule it out.

Cheers

Nige.

Rich, sadly it was the other way round, I got it for the covid but got scared! Now I can get scared with impunity! 🤪😂 only problem is it needs a visor demister!🤪

I haven’t found any other colours yet but I am sure I will.

Tomboy

Hi Martin

Something like the Vic Smeed Tomboy would be good with that engine and lightweight gear, I have a free flight one.

They were used in a duration competition so you may find later issued plans with the rc mods done but it is not hard to do.

Or have a look at other Vic Smeed designs there are some crackers out there, one of my favourites is the Miss 38.

Thread: Tissue over Doculam covering for undercambered wings
23/07/2020 00:04:08

Glad it was of interest Pat, I will have a look over on RCG as I have not been on there for a longtime now, and George inspired me on some of my designs with his construction articles years ago, I will be interested is what he does with the Doculam.

Cheers

Hi Pat

Labelling on these rolls can be confusing, as Doculam is a US product they use feet and inches, the CR confused me at first, not sure where the CR came from but would welcome enlightenment! In fact they use thou for this measurement which is usually down as mil to add further confusion!😳🙄 the 20” is width and 200’ is length of roll as you say the 1” is the core size of the roll, our machines used a 32mm Core, the 1.5 CR (mil) equates to 38micron (mic) most laminating film supplied here is in metric ( which is why I can get confused🥴 thickness being in microns.

the film I have that I thought was 48mic is actually 42mic (I went to find a roll) and is a Matt laminate, it is very easy to use and as you say the joins can be hidden well, what I meant to say is it can be sensitive to too much heat, turn the heat up to stretch or form around complex curves but if you are not careful it can drag over sheeted areas and cause creases which basically stick together far too well! I like the 75mic on larger models as it is easier to use, obviously on bigger areas but is not so sensitive to excessive heat and is more stable due to it being heavier weight wise.

Cheers

P.S. It might be of interest, but application of this film is designed to be applied through a slowish moving machine through a pair of heated rubber rollers under pressure, they can be turned off so only one side heats up ( causes curling issues unless speed, heat and tension are optimum but mostly we used a two roll machine which did both sides, it was not really manufactured to be applied as we do, so I suggest on flat sheeted areas, to hold plenty of tension and I have used kitchen roll laid over to Iron on to stop dragging the film to good effect.

Hi John

I am not surprised it seems lighter, dope can defiantly add a lot of weight like all things if used too much🤭 it only has to hold the tissue onto the film, I used to like a glossy finish when I was a kid, can’t remember how many coats I gave them, looked nice but I didn’t know any better!

That looks the ideal weight of film, the 48mic is a bit too light and can be difficult to apply, if you want some to try PM me your address I I will send some over.

Cheers

Thread: Best modern fillers.
21/07/2020 11:17:57

Hi Phil

Yes it does set quickly, obviously it it goes on thick it takes longer but I only put it on in roughly 2mm thickness at a time, it did take me a few goes to get the mix right but it is not difficult, I found Poly C worked but just lacked something in the sanding but that could be I needed to experiment more, possibly the emulsion being a little thicker was easier to get the mix right, I also found mixing emulsion to the micro balloons a better way as you don’t need that much, also found the bought lightweight fillers can dry out and not work, I added a little emulsion to these and this works well too!👍🏻

21/07/2020 09:57:31

I mix micro balloons, cordial silica or the fairing compound from Bucks composites with emulsion, the trick is not to have it too wet but a nice stiff paste, you can get the match pots in the usual outlets I tend to take some balsa with me to get a near as possible match, Let it dry overnight is preferable but not essential, it sands as easy as the bought fillers but it a little denser and does not crumble away, it feathers out very well, if filming over I tend to sponge on a light coat of basaloc to be belt and braces with it.

I have tried mixing with the water based resins and found the emulsion a better option.

Thread: Tissue over Doculam covering for undercambered wings
21/07/2020 09:47:08

As I have used Doculam for both models and it’s intended use, to get the best out of it just do some samples onto balsa structure using different heat settings of your iron, when laminating using the proper laminator the heat range generally was between 130C and 150C but that was on that machine and dependant on lam thickness and area also we had to take into account too much heat would curl the sheet etc. But to get the best out of the adhesive just run a few tests and get the optimum.

I use the lightest I have (48mic) on small rubber powered free flight, adds very little to the overall weight and only use 2 thinned coats of dope, a Junior 60 was done with 125mic and although I thought this was a little too much has proved to be very strong in use and much lighter than Solartex and about on par with normal film.

In theory , its a good idea to have a spare crew for long flights . Look at the Flying Scotsman with its second crew entering via a tunnel through the tender .

But that spare crew would have to have had sleep , not simply reading a comic , to be more refreshed .

Now, I dont know about you , but I find it pretty much impossible to sleep in economy . Ok , so a nice drop of single malt whiskey with ice helps , but for a good few hours I need to be lying down .

So perhaps North American should have organised a reclining sliding chair , with better sound insulation and black out curtains in the "spare " fuselage , A little shower and toilet facility (perhaps stolen from a caravan ) would have meant that the resting crewman came out fresh as a daisy . Shame about the other bloke....

It just takes a little planning . I cant believe they missed these valuable points. A good interior designer and a Feng shui guru would have had that buttoned up in a jiffy .

My goodness , how we've moved on ..

Who said they didn’t? 😳. 🤪🤣🤭

29/06/2020 17:56:59

Quite right Peter, this is happens when I snatch a couple of minutes on the internet 😳 I was thinking the conversion of the training airframes or at least one I was reading about had been converted to two operational cockpits. 🙄

29/06/2020 16:20:14

Both cockpits were fully functioning, as per it’s original design spec.

29/06/2020 11:02:26

You have to look at the original design spec for the F82 to see why two pilots, designed to be an escort fighter for the B29’s so a range of 2000+ miles and shared workload.

The various versions that came later with the ‘pod’ , the unofficial photo recon etc. some required just one crew member which could allow for the second cockpit to be faired over to reduce drag but I have never understood how that was a good thing in this configuration although I guess it could be trimmed out.

The best thing that always made me laugh was the early Models with the RR/Packard Merlins were relegated to trainers for the later Allison 1710 equipped E’s etc, making the trainer capable of a higher ceiling of operation and faster to boot!

Because it was quickly superseded by the Jet age they were tried in various different roles and were masters in none, not the fault of the aircraft or crews, but there is always odd example that stands out if you research enough and they were documented but these are fairly thin on the ground, Betty Jo was an example that stands out as a record breaking airframe but everything military was taken out (armament and amour plate) and extra internal fuel tanks fitted plus the 4 external drop tanks but when it came to dropping them only one wanted to leave giving more problems making the whole flight success even more credit.

I've been using M J Hardy's book "The North American Mustang" for my Top Flite Mustang build and he covers the Twin Mustang. He observes that the P82 was the only twin-fuselage version of a single engined wartime Allied military aircraft to go into production in any numbers. The first XP-82-NA was Packard Merlin powered with "handed" airscrews rotating inwards. He does not say whether this resulted in the aircraft not taking off.

Hardy states that the fuselage of the P51H had " an extra section 4ft 9in long inserted aft of the radiator fairing and ahead of the tailplane".

Hardy notes the outer wings were modified to remove the guns and undercarriage. The main u/c was now repositioned to the wing root pivoting on the main spar and retracting into the centre section.

Interestingly, options for use in the fighter bomber or ground attack, even an interceptor, role the starboard cockpit could be removed and replaced by a metal fairing both reducing weight and drag. The interceptor would have had internal fuel and no external stores.

Other interesting points were that the twin retracting tail wheels were cable operated from the main wheels, these now being directly in front. The Allison was only installed in the 3rd XP-82 and did not have contra rotating props. As both the USAAF and North American preferred the Merlin this prototype, XP-82A was never completed. The first production version P-82B-NA reverted to the Merlin and 500 were ordered. It was not until the P-82E was ordered that the Allison replaced the Merlin. It was the first time that it had appeared in a production Mustang since the P-51-A and A-36A. It was now "wearing" handed Aeroproducts 4 blade props which also now incorporated feathering.

In the Korean war they were in action from the beginning because of their range. They were credited with a Yak 9, Yak 11 and La-7.

The now F82 was superseded by jets and was out of service at the end of 1953.

A good P82 to model might be the 9th P82B which was flown from Hawaii to New York non stop in 14 hours 31 minutes 50 secs. It was named Betty Jo after the pilot's wife, Lt Col Robert E Thacker. The other pilot was Lt J M Ard. The guns and armour were removed and extra fuel tanks were fitted behind the pilots' seats which, with 4 x 310 gals, gave a total fuel load of 2,215 US gals and a gross weight of 30,000 lb.

Thanks for that info Peter, it now makes my scribbling a little more understandable! The point is the ‘H’ Fuz as Ron has said, I think I will get that book👍🏻

It is slowly coming back so once I have everything in front of me it may well get a grey cell working.

Talking of Lt. Col. Thacker, I had the great pleasure of meeting him at a Mesa Jet meet in AZ back in around 2007 or so, in his 90’s and flying a F15 Model very well! I had intended to do the F82 as Betty Jo which is the last time I enthused about the project but life got in the way again, hearing the story from the horses mouth as it were was inspiring, the friends I was with started the conversation as the evening before we had a conversation on what was the best project you never got round to doing! Sadly it still is!🙄🤭😂

P.S. Sorry it may have been 2008 in Mesa when Lt.Col. Thacker was 90, I know they said he flies better than most half his age !

That’s helped me understand my 36 year old scribbling, in a note book I have a very rough sketch of the Fuz with 57” marked on it, must go with the photos I have.

I have got find everything now!
