LOLLLL!!! The question, if it was copied directly from Facebook was not correctly phrased. When I first saw this on the web, about 8 years ago it was phrased like this: If an airplane is on a conveyor belt runway and the runway moves backwards at exactly the same speed as the plane moves forwards, can the plane take off. And the answer is clearly yes. And yes, it is definitely a question that can ONLY BE ANSWERED BY PHYSICS. The solution. Boeing 747-8 = 266,000 lbs of thrust applied on take off surface moving backwards = one planet's worth of thrust connection of surface to the aircraft = the wheel bearings reverse thrust applied through wheel bearings = 5 lbs per wheel (guesstimated worst case) For every action there is an equal and opposite reaction. Therefore the thrust from the engines pushes the plane forwards and it WILL reach rotation speed. Any connection to the ground is eliminated by the wheels. ---------- Teehee. I work for an aerospace components maker and I asked quezzy this to a few guys at work about a month ago. 3 machine setters and one engineering manager. 2 setters in my department decided the answer was no "because the ground". One setter from the lathe turning dept said no, initially, but wait a minute, yes it can, there's no effect. He has flown RC in the past. The engineering manager? "Yes it can, there's nothing to stop it." So now we know why he's a manager. So, if you're already a manager and already answered no . . .

Obviously I'm not going to suggest that it's a sex aid. But are you starting a night club?

Poundland, your one stop shop! Well, almost.

Soo, as an infrequent flyer, BMFA country member and member of a slope soaring club that's sort of based at a landing strip on the edge of Dartmoor and does not insist on flying certificates, who is occasionally flying from a farmer's field with verbal permission granted, about 2 years back, the 'prototype' regs will have me breaking the law pretty much all the time? I can't find a smiley that shows,"I'm old enough to know what the hell I'm doing and to do it without affecting you or anyone else so bog off and leave me to my own devices" My bad was to sign the petition in a knee jerk before coming here to read all the sense that's all too obvious. I then realized that I knee jerked to the knee jerk petition against the knee jerk proposed regulations! I'm hearing faint strains of Mother Brown in the background!

Posted by ken anderson. on 10/09/2016 08:11:29: here's my story...I've been a member of one of the well known break down companies for 12 years,each renewal they attempt to put it up(even though I haven't used the service)and after I phone complaining they always come back with the line -your a loyal customer, the manager say's we'll give you preferential treatment etc...and the price stays the same? out side the local supermarket they occasionally have their stall set up and advertise-join today for £50-£70,i asked the man what the crack is for the special price-he said nothing they would get the same as what I pay for £100+and i'm supposed to be a platinum member ....so I was /am confused to say the least....... A.A I hear you say ken Anderson...ne...1 motoring dept. Eh? Eh?

Posted by Martin Whybrow on 10/09/2016 00:48:27: Chuck, I suspect our recent breakdown may have had even you stumped for a solution to getting home; my wife's car snapped its crankshaft whilst in lane 4 of the M25! The police got us to the hard shoulder, but we needed the AA to get home. Holey Moley!!!! What a horrible thing!!! Oh my goodness, I can imagine how scary that must have been! Were you able to get out and stand between the central barriers or somewhere safe?? . Yes, no, obviously the special attachment on my Swiss Army knife would have fixed the problem before it happened.

Posted by Tony Bennett on 09/09/2016 21:36:54: i have AA breakdown cover as part of my bank account, came in useful when the vw camper broke down. recovered to home for no charge. I had that too a few years ago. But glad to not use it though.

Posted by Percy Verance on 09/09/2016 21:36:08: Well Chuck, that's absolutely fine. But for those of us whom have no wish (or desire) to lift the bonnet and tinker, we go for the reassurance of breakdown cover...... Hopefully I shan't need it, but as my car is now out of it's maker's warranty I'm happier with some cover. I'm thinking that if I have it, I probably won't need it...... I definitely understand why folks go for breakdown cover. And I'm probably kidding myself as t what I might or might not be able to repair. To be honest, I'd prefer to have a much older 'classic' car. One without any electronic malarkey. But they are never too good on fuel consumption.

I know his name from a few years back reading MBUK mag. The man's a legend! Crikey! Two displaced vertebrae!!! So much pain!!!! But man! He's just doing what he wants and making the best of it. Good man! My dad got a crushed vertebra after a bad fall playing tennis, when I was seven, about 56 years ago. He was an army doctor himself at that time, so I guess he got some of the best help that was available. Thankfully the treatment and physiotherapy is 50 years better now. Lets hope Martyn can progress. Edited By Chuck Plains on 09/09/2016 21:27:54

Very interested to see what have you! CNC milling is my day job. I have a box of scrapped off parts and off-cuts here if you think you might need something more than just the sheet ally from B&Q.

Thankfully, I feel confident that I can cover any eventualities myself. Swiss Army knife in the door pocket and all's well.

AH. I thought you meant a box of apples or something. That would certainly mess up your CG!

My only experience with fibreglass to date is from repairing windsurf boards 2.5 decades ago. But yes, if the cloth is heavy, it needs a larger flat area to flatten itself out on after turning a sharp-ish corner. And two layers of thin glass cloth can be stronger than a single layer of double weight cloth. But you mentioned bandage Treb. That's made me think that trimming off any woven edge on the cloth could help it to conform better by allowing the weave to open up on all sides.

Posted by trebor on 26/08/2016 19:57:56: I can see some fibres if I zoom in, first glance at the picture it looked like a bit of old covered balsa. Mind you wood might be better for you than foam Ah, well, the bread definitely contains fiber, but the fibres in the wing thing are carbon tube struts that run full span top and bottom. The structure is extremely rigid after gluing them in, I really couldn't believe it. A thread about that there wing will be posted soon. now I'm home again.

I seem to have confirmed this method for myself before I found the thread. I'd been seeing forum posts and a few videos about p { margin-bottom: 0.25cm; line-height: 120%; } I beams etc and decided to hack my old flexi glider wing to check my thoughts. Being a cheapskate I have stuck with the "Experimental Airlines" style of making wings up till now. They work and cost almost nowt. But this wing was used with my Easy Pigeon attached, and it flexed in a very entertaining way, using my 20 year old lengths of pultruded carbon tube as spars. I knew they wouldn't break as I'd always used this material as kite spars and knew how tough it is. So I now have one on top and one on bottom, both glued in, with the top one being full span! The covering will literally be touching the spars once finished. And, compared to just having the carbon tubes lurking inside 'gaps' between the foam, I would estimate that this wing is now four times stiffer than before. I shall be typing up a thread on it just for fun. Hmm, what should I do for a title? Thinx . . . something like . . . ah yes . . .

Analogue cheese? Yes please! I'm hankering after being fully vegan this year, though it may not happen due to disorganisedlyness. Haha! Ahem. So far I can recommend Vio Life, it really is a good mild cheddar impersonator.

Posted by trebor on 21/08/2016 12:14:40: Is that old bit of balsa part of your diet too ? Heh, that old bit of under flooring insulation foam is deffo part of my diet Mr Trebor sir. It's all over the place here, apart from under the floor. And I've just spread a thin coat of water based varnish on it, in preparation for the decorative strawberry jam finish! But that's a whole 'nother thread.

I'm not prepared to travel any distance to fly my planes. I'm only prepared to fly them either in my back garden (40ft x 12 ft ) or right from my front door. Unfortunately, I have just two choices. One means driving 12 miles to the club site at Little Haldon. And the other choice involves travelling about 5 feet vertically off the edge of the car park at work, then I can walk a few feet and launch a plane across the fields of the Creedy Valley. If the wind is in the right direction or it's very light to calm.

Posted by Mark Kettle 1 on 21/08/2016 12:51:20: I've just done a snack as well Chuck. That wing plan form really is very Vulcan like! Hmm, you don't think . . . ????

Congratulations Kieran!! Mine was so much better, but you won!

Built two planes already on a Sunday morning.

So, you say that something like this flew at a place called Kittyhawk? Yeah Wright! Time for another nap.
