Siegfried Posted March 26, 2009 Posted March 26, 2009 Yes, Hinckley and Sinners sigfigs did survive...unfortunately... That's good; I am getting rare you know... Quote
WhiteFang Posted March 26, 2009 Posted March 26, 2009 I can't believe that this discussion has span till so far, and Dennimator has certainly done a great job by proving his point well. Now, it's time for the accident investigation agency to check the cause of this accident. Quote
Zorro Posted March 26, 2009 Posted March 26, 2009 Well done Dennimator, I love your little movie! And I still need a Sinner and Copmike minifig as well ! Quote
Buttons Posted March 26, 2009 Posted March 26, 2009 Now, it's time for the accident investigation agency to check the cause of this accident. I wonder if that aircraft had a black box? Quote

Dennimator Posted March 27, 2009 Posted March 27, 2009 (edited) I can't believe that this discussion has span till so far, and Dennimator has certainly done a great job by proving his point well. Now, it's time for the accident investigation agency to check the cause of this accident. Already done, scroll down a bit. I would say the runway was not long enougth to allow the plane to reach take off speed. I would say something else... Here are some pics taken by a security camera in the cockpit (while the plane was still up in the air): I wonder if that aircraft had a black box? It certainly did, look for yourself (Oh, and don´t care about what´s happening in the background, the LEGOville cops saw the previous pics before you guys did. (Yes, I have finally named my tabletown, and yes, it´s the name of the DUPLO city , too.. TLG stole the name from me. ) Edited March 27, 2009 by Dennimator Quote
Skipper 24 Posted March 28, 2009 Posted March 28, 2009 Loving your test flight. Sinner and Hinckley, I thought better of you two . Great video . Quote

Brickthus Posted April 13, 2009 Posted April 13, 2009 OK, we've established that a LEGO MoC can fly for a short distance if it drives fast enough off a ramp, but can a LEGO creation fly under its own power? I did a few experiments to see. The first was to create a replica of a bird toy, with dual flapping wings. The idea is to force air backwards and down at an angle, whilst making the wings suitable for gliding, which is what the toy does when the wings stop flapping. Unfortunately LEGO is rather heavier than the polystyrene body of the toy. I have obtained some thrust from the wings but not enough to move the model. The other experiments involve propellers, using a 4000 RPM motor. The aim is to make a quad rotor helicopter like the fire service use with a camera for looking into burning buildings. 3- or 4-blade town propellers do not provide much thrust. 4x8 plates with 12 studs on top provide more thrust. I put 3 at angles on some 24mm pulleys. The first go ended up with a blade-off incident. Good job it didn't fly off in my direction! I fixed the plates more securely and got more thrust out of it. Still not enough to lift the weight of the motor and propeller when dangled over a table though. I tried with some of the blue polypropylene sheets from the Technic Mars Rover. These are light, but not efficient as propeller blades, even with axles supporting their shape. I might try with two of the sheets with something between them, in order to try a wing shape. I think aerodynamics is the key to this. I have other experiments but the blades are not very aerodynamic because they use the underside of plates. There was a 1-piece propeller from a Technic plane years ago. Would this provide some real thrust? I'll have to check on some scales how much thrust each experiment produces, as well as taking some pictures of the models. Mark Quote
just2good Posted May 23, 2009 Author Posted May 23, 2009 It would be cool if they also made that it could fit 32 minifigs. Quote
just2good Posted January 8, 2012 Author Posted January 8, 2012 I think it's time we bring this topic back. LEGO City has done just about every gimmick (but I'm not calling the theme gimmicky ). Floating boats (which didn't float well ), motorized trains and boats, light up minifigures, advent calenders, combination sets, ect. So I think they should start doing (cheap) 9v race cars (possible hint of racing sub-theme?) and planes/helicopters. What do you guys think? Quote
Hinckley Posted January 8, 2012 Posted January 8, 2012 What do you guys think? I think nothing has changed since the last time it was discussed. The limitations remain the same. Well, there is one change: LEGO has abandoned 9v motors altogether anyway, so maybe power functions, but still, the cost would probably be exorbitant and marketing something that flies that is that big could actually be considered invading airspace or building a weapon. Race track, perhaps, but have you seen an XL motor? That'd be a pretty large scale. I don't think it's feasible... Quote
rriggs Posted January 8, 2012 Posted January 8, 2012 I think nothing has changed since the last time it was discussed. Well you say that but LEGO has been through a phase of using cheaper plastic and putting holes in the lugs in the bottom of bricks so that must save weight? Also, I haven't tested gravity recently but maybe that's changed too? Cheers Rog Quote

Pingles Posted January 8, 2012 Posted January 8, 2012 That would be a fun forum contest. The most spectacular Lego Plane crash video. - No special effects - Single impact - Must be in flight when it impacts The prize? Replacements for damaged bricks. Quote
LEGOman273 Posted January 8, 2012 Posted January 8, 2012 How about a glider made out of Destiny's Bounty sails? Quote
Theo Posted January 9, 2012 Posted January 9, 2012 Is it really impossible to make a LEGO helicopter? Quote
Hinckley Posted January 9, 2012 Posted January 9, 2012 Is it really impossible to make a LEGO helicopter? You tell me. Go make one. Make sure there's a tail rotor. Quote
Theo Posted January 9, 2012 Posted January 9, 2012 (edited) You tell me. Go make one. Make sure there's a tail rotor. Well, I'm just a LEGO town guy, and I am not good at physics neither, so...I would love to hear an answer from an expert Here in Moschato(Greece) where I live, on Saturdays I see many people go to the beach, having different types of RC planes, making them do all the kinds of manoeuvres and it's pretty cool (and there is no tree there, only small bushes, so I'll have nothing to worry, unless I drive the plane to the water of course) Edited January 9, 2012 by Theo Quote
Dakar A Posted January 9, 2012 Posted January 9, 2012 I'm not sure where on teh interwebs I saw it, but if someone were to scale down, say a B2 bomber (158,000 lbs) to minifig scale (1:48)the model could feasibly weigh aroung 3280 lbs. Now just tyo find a motor to power it.. Dakar Quote
Pingles Posted January 9, 2012 Posted January 9, 2012 It would just take about 1600 battery packs. Reminds me of the real rockets where most of the fuel is used to lift the fuel! Quote
MrBeaver Posted January 9, 2012 Posted January 9, 2012 Is it really impossible to make a LEGO helicopter? Sorry, I haven't made 5 posts here yet so I'm not allowed to post links. But I want you to check out the video on youtube with yellow RC helicopter. Video called Lego RC Helicopter by makinggodlookgood Very cool RC helicopter. Unfortunately, if you look closer, you'll see it's far not the minifig scale, but a brilliantly stylized model Quote
lightningtiger Posted January 9, 2012 Posted January 9, 2012 'Pingles' had sort of a suggestion...a contest...Power Function City....be that road or air or even structure....a MOC or modified city set....well an idea yes ? Quote
Dakar A Posted January 9, 2012 Posted January 9, 2012 What Mr.Beaver meant to link. Body's built of fibreglass, though.Dakar Quote
