BARCS Open / 100S models of Yesteryear (Pre-2000)

Presumably you have a Cobra either in storage or being prepared for my hangar then Pete!

Must admit, as I am having Mike Holtby make some V tails for me, I am considering getting some short tips made, so that I can make the Contest Plus a Contest too, if all else fails!

However, when I asked for a pair of v-tails I was asked whether I wanted small or large! This is not apparent from the parts list. After some discussion, we decided that for my use - mainly thermal - the larger tails would give me greater flexibility.

I imagine that a larger tail area will give the model better stability in the turn, hence my comment "looking forward to trying out the v-tail electric version", and have not given up on the Plus yet.

Best regards,

Jef

Hi Jef

No, no ulterior motive, I haven't got a Cobra in the spare room, I used to have but not any more!

Trouble was I just couldn't assemble the thing one-handed! You have to push the wings together using a couple of flattish ali blocks then invert the whole thing and insert an extra long T-handled allen key into the underside of the fuz, waggle it about and get it to pick up the threads of the wing retaining bolts while fiddling the two leads from each wing panel into the fuz (sort of a la Luna)

Sometimes I was 20 minutes assembling the bogging thing - once it's together though everything's peachy

Sorry, I hope I didn't sound as though I was trying to put you off modding the 3.3 it's just that I didn't want you to be disdappointed if you couldn't "fix" it - several have tried!

Regards

Pete

:blush: Just checked, for the first time, the CG location on my Contest Plus (which is well rearward at more than 100mm behind the LE). Have now added two ounces (58g actually) of lead to the nose and this has moved it to about 95mm from the LE, which may be closer to the optimum position for my style of flying... although I suspect that this may still be too far aft for the big wing T-tail version, which will require a 'safer' balance point than the smaller wing version, as the tail volume is the same on both.  

 

Reduced the additional dihedral slightly and this looks right now, so I am hopeful of a less hairy session tomorrow / whenever the weather looks more suitable.

So, today in the Tonbridge Multi Launch Comp, I had a line break during the pre-start 30second launch window of Round 1 Slot 1, came off at about 75m and flew the slot out landing in the last second for 9m59s and 30 bonus. What a great model the Sharon is proving to be... the slippery ground surface caught me unawares and the model slid through the spot and out the other side, broadsiding and stopping backwards, with the flaps down. The ground was hard and one of the flap servo arms broke (I was lucky). 

Next round I flew the Calypso Contest 3m and really needed something other than flat calm conditions to get the best from the model. Feeling despondent, it suddenly dawned on me that I should be trying to get the virtually unflown Calypso Contest Plus out, and using the competition to get it properly trimmed. 

A couple of rounds later, the model was circling sweetly and even in the really light lift was able to get to very good height before rolling, looping, flying inverted (and sliding through the spot in the closing moments of the slot! Fortunately without incurring damage like the Sharon). 

Reasons the Contest Plus didn't fly well to start with...

Insufficient Dihedral - just a couple of degrees is all that is needed at the tips.

CG too far aft. The large wing needs either a larger tail volume or a more forward CG than the smaller wing variant with the same fus and tail. Pretty basic stuff when you think about it.

Don't use too much up elevator in the launch preset, I was overstressing the line and causing my line to break and knots to undo.

Not enough camber in, in the full thermal camber position, so when I slowed it in the turn, the wing was stalling. Once I had established that the wing needed more camber, the model was transformed. 

When I was finally flying the model in a proper state of trim, Deryk Collins was flying his Eliminator 134" in my air too (he seemed to think the air was his!) and to avoid a collision, I flew out of the lift for a while, then went back for some more, when his model had climbed 30metres or so. It was nice to have the Contest and the Eliminator doing battle - just as they would have done back in the mid-nineties.

Did you notice that in one of the rounds at the Tonbridge Multi-launch that I flew my original R/E Airbrakes Red Fendon, some 30 years old and recently electrified. I know nostalga aint what it used to be but it was sure nice to see the very distinct shape of a Fendon in the air once again at a comp. And yes, it flew out the slot too! :)  

Literally hundreds of Fendons were built during RC Soarings heydays, (just wish I had sold as many plans as there were Fendons built!) I used to produce Plan/ Foam Wing Packs of the Fendon for some years before stopping due to starting up my current business which took over all my time. If memory serves me correctly I think I produced close to 140 sets of foam wings which in those days were eagerly snapped up. Seeing one's own design built and flown by so many modellers was a fantastic feeling even when I was beaten (often) with my own design! Great memories.

Yes, well done Colin. It was good to see the Fendon E. There was a good selection of relatively young nineties models there, too.

It seems that the ten minutes originally set for the task is just as hard to get in sink now, as it was then... and landings seem to be easier for those with the time to practise, regardless of their model's age.

I had to laugh when an old design 100"S model, flown by my team mate Tom Frankland, absolutely destroyed the landing spot plastic plate (smashed it into two equal halves)! The model was relatively unscathed and went on to complete the day.

The Contest Plus is very efficient at returning from too low down, then flying through the circle because I still can't believe that I would need to use the brakes, having given up all hope of getting anywhere near the target. 

Defo need more practise!

Here's another Fendon, patrolling off Colley Hill on 11/12/13 – a ‘lucky number day”(?) and a very lucky photographer (me) to be there in that special misty weather….

Do you know whose Fendon this is as it looks like it might be a rare example of the Fendon 4 or 5 which had ailerons and flaps as opposed to the original versions (1,2 & 3) which were R, E and spoilers. Many Fendons were bult from my plans & plan packs but relatively few as far as I'm aware were 4/5 versions. Happy days!

Cheers

Here is a pic of a model from the nineties, that I had not heard of until recently, a Frits Donker Duyvis design called the Fletcher.

Pic supplied by FDD himself!

Hi Jef

A good friend of mine, Pete Hemsworth of the ISA, still flies his Fletcher today, but as a "high end sport" model, he swears by it

I now have three Proton 140's - one via your goodself, one my old Proton I flew for 20 years plus, (which I sold just over a year ago to a fellow ISA member, and, after 20 years of hard comp flying in my hands, it took him 6 weeks to smash it in a mid-air), now fully repaired and re-furbed and ready for its second maiden, and third a Proton 140E (a version which John Shaw never actually designed nor saw, due to his passing)

This string wouldn't be complete without a pic of a Proton 140 - I'll see if I can upload one soon......

BUT the icing on the cake has got to be the BRAND NEW, unflown, Calypso Contest "E" I haven't quite completed yet, but will hopefully soon, which I'm just 90% finished re-converting back to a pure glider, with the "E" option still available for when I finally dink the "standard" nosecone....... kept that little secret quite well, haven't I?

Oh, and I've got a Multiphase 142 and a Hi-Phase (fuselage only at present) to keep me going this winter.....

Finally, can I invite every one of the contributors to this string to ISA Nostalgia Day on Saturday 19th September to do their reminiscing the correct way, face to face, and hope I can get pics of as many of their "period" offerings as I can, on the day - now won't that be a pic!

BTW Please e-mail me direct or PM me, for more details of Nostalgia Day if you are able to come

Regards

Pete

Thanks Pete,

I really am going to try to be there for this nostalgia day on the 19th Sept - too many have passed me by! It is my wedding anniversary on 20th Sept though, so I will have to dream up something very special for us to do on that Sunday (so that I have plenty of brownie points).

The original post on this thread has pics taken (by my Dad) more than two years ago, of the Proton (while it was on the bungee at Bartletts), which was mine and you now own.

The electrifiable Contest... :drool: Interested to see how you are doing the interchangeable nose thing... and is it a tee or a vee? And if it's a vee, does it have the large or the small tails?  

What is a "high end sport" model? Something for a windy day perhaps? :mellow:

Thanks again for the invite. See you there, if not before.

Jef

Phil Taylor's got a Fletcher as well. His is in a very classy Mondrian colour scheme. I didn't know it was designed by Frits, though!

Hi OiPigFace

If you take the time to scroll through the online library of "Soarers" you'll find an "F3B Special" issue which, I think appeared in 1983 and was subsequently used by Sean Walbank in the "White Sheet" where Frits explains his design philosophy for the F3B Fletcher

Even today he's still providing designs for planes, currently, I think, he's designed a BIG F3J/Cross Country version

It was seeing a picture of Phil Taylor's one at Thurnham (on the RCMF forum) that prompted me to first contact Phil and then Frits.

A design that sits very well in this section.

Hi Jef

It's a "V", don't know if they're big or small, with white topsides and a classy sort of "duck egg blue" underside - perfect camouflage for disappearing into a clear blue sky at height! - I'm thinking of adding (removable) black tape stripes on the underside - just in case....

The "E" fus has slight differences to the standard one, you should be able to see them on the fus  you got from me in p/ex for the Proton, where the sheath nose has cooling slots in it and the nose tip removed. The rudder and elevator servos are now under the wing seat opening, allowing me loads of room on the standard keel to fit a 2200 Lipo recessed into the keel on one side, and the receiver on t'other - oh, and a Hacker motor and 60 amp ESC as well

BTW isn't the one I got from you ex Murky Knights? I know one of them is because I was talking about my Protons with him recently, he was certain at least one of them was......

Oh and also, the high end sport plane was my description of an F3B/F3F model that ISN'T used for racing - just sport flying

The Multiphase I got from the "Dark Lord" at the BARCS AGM B&B two years ago.........thanks Greg

Regards

Here's a photo of my competition glider circa 1980. It was started by the late Ron Gardner, like me then a member of the Thanet Model Flying Club, with a Proton fibreglass fuselage, a Bluebeast wing modified by me, my own design fin, rudder and all moving tailplane. I named it IRONIC and was quite successful in the Kent Interclub competitions and I still have most of it as one half i.e 6ft of the wing disappeared in 2 moves in my absence between 1994 and 2009. I had previously bought from Ron a solartex (horrible stuff) covered Bluebeast that was shot down in a frequency clash (another person was flying in the wrong slot) leading to an on field purchase from Ron of his Soaron Sunshine 100in. that I flew to beat him in the competition that day to my amusement but not his! I still have the Sunshine that was flown again in 2010 after an18 year rest. Yes I edited my naked body from the photo that was taken in Holland during one of our many annual twinning competition with the Delta Club Vlissingen.

Yes, Pete, I bought the Proton from Murky Knights, in a (too good to miss) deal along with a Balsa Cabin Fantasia 100" RES for my Son, Gary.

Gary flew the Fantasia to good effect in his teenage years, while his Grandad and I were building three Trilogy 6 models. Two still survive 20 years on. We sold the Fantasia to buy a Xantia semi-mouldy for Gary when he was 16.

The maiden flight of the Proton under my ownership was tragic. I had the rudder control reversed, despite checking it several times and reassuring myself that all was well :(.

The wings were neatly packed into a black bin bag and fellow club member and free-flight guru, Bob Wells, voluntarily rebuilt the model and glassed over the tissue on the tips.

I have been seriously lucky with the generosity of my fellow club members (Anglia MFC and EQFA especially, and also Canvey Island MA) on many occasions. :)
