Welcome, being a lifetime leaver, and returner, what you learned in the past is still there. But it’s not always still right. As ever, game of blood. But addictive. I still think however, the lessons learned from when you left, pre computer radio are valid, particularly setting it up to fly nicely from the mechanical setup, are still valid.

It’s when it’s in a dive, and you forget, and the engine dies, speed, ideas, hight, springs to mind. Don’t ask where this knowledge comes from.

Full size airfoil, efficient use of power, and chuck ability, and all the wires holds it in place. Miget size airfoil, less efficient, don’t like that front end if I slam power and up on (nasty stall). (Note I have a lot more power)but crucially, who fancies doing a tensioning regime every flight.

Who wrote that, oil industry influencer? Just saying.

Aye, Rich Griff mentioned Max Boyce, remember his song, “The outside arf factory” from the era. ”and they broke the mould, the golden mould, that once made Barry John”

Welcome, sounds like you’re sorted, club, and if trusted, and I assume he is, an advisor as to who to trust for knowledge.

Nylon, that’s a blast from the past. But the tip re heat. Thank you.

I once had a mate, he was building a serious yacht from scratch. His plans were reduced scale, and some of it needed to be full size for reference, like some of the hull formers. So he drew them on the lounge walls. Wife arrived home. Still smarting from an earlier incident, where, the heating being non existent in the garage, he had undertaken a repair in said lounge of his motorbike and got caught. Soon to be single.

Has He got a ticket boyo?

Jiffy Davies, that little migit , what could once turn on sixpence, and opposition inside out. I can’t spell

Don’t see much opposition.

When I was a little sprog, 10, 11?, I looked at the ads, back of aeromodler. And drooled over a KK Falcon. I will have to sort it one day. I have a plan to build, and am sure it can be built to a stupid weight with 3 mm depron, 29 micron doculam, a bit of balsa, and a battery up front to give an hour of flight time. And I will need a beer, and a deck chair.

Or Simon, recreate the original, small number of watts to power it, stick a pound of lead on the CG, to recreate the radio weight, and it ceases the desire to react like a feisty disco dancer, and it reverts to the far more natural corpulent old age slow waltz.

I had a lovely afternoon, just had second cataract done, had the usual ageist discussion with the dispensing optician, and after a comment you have better eyesite that me, got my very satisfactory new transition lens glasses. 15.5 °, I think there was a bit of wind here and there. Wall to wall sunshine. Good turnout. Rusty, flew an electric Tundra. 6 flights, 30 landings. Most satisfactory.

I used to use small lead batteries. Accepted, poor decipline in keeping it charged didn’t help, but they take all day to charge, and don’t do many starts before they start to struggle. Any way I also used 8inches cut of a broom ( blessed with a shortish wife, who wouldn’t notice). It got me physiotherepy, 5 one hour sessions a week for over 4 weeks. Painful. golf bag on wheels is a golf trolly

If it’s as memory, it has an under camber on the wing. It is what it is, a model design for single channel radio guidance. It has a power setting where it will climb nicely, loose hight in a rudder turn, ad infinitude. A bit of down trim will make it use more power to climb, and it’s very slightly faster. Trainer it is not, unless he is being trained as a single channel pilot. As you say yourself David, you, with your experience live with it and compensate. For a biginner, I suspect something like an Foss Acrowot, modest power would be easier. BTW, I’m not saying Acrowots are trainers, just easier than a Radio Queen.

I use 3s or 4s batteries. Don’t really care. But I do make sure it has a maximum prop swing to get up some speed before it gets loaded against compression. With either I’ve not yet welded anything up, except on one occasion, I had a 24v Dynatron unit, and a 4s battery, almost flat, and I welded the switch when it stalled. I think, willing to be disproved, ( not my game) that the amps max out at stall, and that’s the heat peak that causes an arc weld.

A trade secret, keep it safe. Criminals are liars. “I swear on my babies life, officer” They will say granny is a bully if it suits.

Nick, you are so right. I remember being in a queue, my Building Society being taken over, to collect new passbooks, or whatever they were called. Nice young lady handed mine over, I noted interest, balance, rate of interest and before I turned away told her the balance was wrong. Not believed, patiently explained, I couldn’t estimate compound interest, but estimating not less than £x interest is simple, sort it out please, and handed it back. They paid out. No apology, naturally.

Back in 1972, I was undertaking, what is now back in fashion, a 5 year degree apprenticeship with ICI. In their Soulth Wales fibres research department, in the lab next door, to where I was trying to improve the tensile strength of polyoxadiazole fibres, I found they had an electronic calculator. I used a lot of maths|number crunching to solve statistic equations wot would suggest likely mixes. Godsend. It sat on a bench, was the size of a couple of shoe boxes, did the work of a basic calculator, and cost, a couple of quid more, than a brand spanking new MGB GT Convertible. Still can’t spell.

Ditto

Just read this, life gets in the way of building, and this build is still stalled. I’ve just had the second cataract done, so eyes sorted. Bit of heart surgery next, and that’s me sorted. Workshop still a mess, but I am determined to sort it out before I get chopped, so I can start to get backlogs done during convalescence. I also have a cunning plan. Missus is thrilled, she’s getting a VW Transporter, converted to my design as a motor caravan. Full hippy wanderer. Ooo, mon Cherie, she coos. It just so happens, can’t think why, but it , by happy coincidence, will have racks that happen to carry large aircraft fully rigged.

I think it’s a TLAR. A Foss own design generic airfoil, nice general function section, but not fast. A lot of kit buyers take root and tip sections onto paper, I know I do, but I’ve never built a Wots Wot.

An RM Aerobat sorted me out after a very long layoff. And a Tyro with a Fok 15 was a first venture into RC flying.

If the problem is the scarf joint, and they don’t look good, why not reinforce, 1/16th,light side of medium, both sides of the scarf. Cut the infills with scarfed ends, lower edge above the main stringer edge, so it’s invisible under the covering. Glue as desired.
