Epic Technic Posted August 22, 2015 Posted August 22, 2015 (edited) When building a Lego sailboat today, an idea popped into mind. Using rudders as wings on a plane. Of course it would mean using actual rc plane electronics but they do have a symmetrical airfoil. I would love to see someone try and make a plane using these as wings.

I would love to see someone try and make a plane using these as wings. That part has no where near the surface area that an RC plane would require. Most planes don't have symetrical airfoils for the wings either (the exception being some earobatic aircraft). Quote
Sariel Posted August 22, 2015 Posted August 22, 2015 Can we please not start the same discussion again? Quote
nerdsforprez Posted August 22, 2015 Posted August 22, 2015 Can we please not start the same discussion again? Could not agree more..........The issue stems so much further than even physics and mechanics (which I will not elaborate on). Just not gonna happen folks for a myriad of reasons..... Quote
dhc6twinotter Posted August 22, 2015 Posted August 22, 2015 Can we please not start the same discussion again? lol! For the record, I'm part of the camp that thinks a 100% Lego RC airplane will never achieve controlled flight. Quote
Sariel Posted August 22, 2015 Posted August 22, 2015 lol! For the record, I'm part of the camp that thinks a 100% Lego RC airplane will never achieve controlled flight. And I'm with you on it, but you know some people are immune to reason ;) Quote
Gnac Posted August 22, 2015 Posted August 22, 2015 Does it keep pushing, or does the mtoor at some point in time stop as it's controller realizes that it won't reach it's final position? I would suspect that Lego has either a controller that is intelligent, or a current protector that safeguards the motor. Either way I don't expect this to be a case where you can fry the motor, it is a too easy fault not be to have been taken care of by Lego. The motor does appear to keep pushing further for a second or two, but then it gives up with a little electronic *squeak*. Quote
Epic Technic Posted August 23, 2015 Posted August 23, 2015 That part has no where near the surface area that an RC plane would require. Most planes don't have symetrical airfoils for the wings either (the exception being some earobatic aircraft). I never said it would be a big plane and with the correct angle of attacks it could work. lol! For the record, I'm part of the camp that thinks a 100% Lego RC airplane will never achieve controlled flight. I literally said that you would have to use actual rc plane parts. Quote
Captainowie Posted August 23, 2015 Posted August 23, 2015 Can we please not start the same discussion again? Why not? It's been long enough since the last argument, about time it rolled around again ;-) Quote
Nalyd997 Posted August 23, 2015 Posted August 23, 2015 Why not? It's been long enough since the last argument, about time it rolled around again ;-) Don't you mean flew around again? Quote
Epic Technic Posted September 20, 2015 Posted September 20, 2015 (edited) I was feeling inspired today so I looked up 'magnus effect glider' (as any normal person would do) and came across this (which I highly recommend building) : I was truly mind blown. I was thinking if and how it could be done in LEGO. Any ideas? Edited September 20, 2015 by Epic Technic Quote
Saberwing40k Posted September 20, 2015 Posted September 20, 2015 I was feeling inspired today so I looked up 'magnus effect glider' (as any normal person would do) and came across this (which I highly recommend building) : I was truly mind blown. I was thinking if and how it could be done in LEGO. Any ideas? I'm going with no. Thing is, I think the Magnus Effect is just too small, even for that thing. Quote
Jeroen Ottens Posted September 20, 2015 Posted September 20, 2015 (edited) The Magnus effect can be quite significant if you have a long enough path: So if you are living near a high structure there should be no reason why it can't be done with a contraption made of Lego Edited September 20, 2015 by Jeroen Ottens Quote
Saberwing40k Posted October 1, 2015 Posted October 1, 2015 Maybe somebody should build one of these instead: Kress Truck: Quote
Kman860 Posted October 10, 2015 Posted October 10, 2015 lol! For the record, I'm part of the camp that thinks a 100% Lego RC airplane will never achieve controlled flight. Just to (try) and put this argument to rest, here's a question statement-Lets assume we had a properly sized piece to build a wing, the right motors, etc, etc, a lego plane would never fly just because of the sheer weight. Maybe somebody should build one of these instead: Kress Truck: Someone should seriously build that... Quote
1974 Posted October 10, 2015 Posted October 10, 2015 .. lego plane would never fly just because of the sheer weight. It has nothing to do with weight, heck not even aerodynamics much, it's all about POWARRR! And we'll not see such motors from TLG Even the much heralded buggy motors are week sauce compared to even the cheapest proper RC motor (380 type Quote
Moz Posted October 10, 2015 Posted October 10, 2015 I think Lego could fly at least as well as that basketball... not quite straight down, and with a fairly low terminal velocity. Some of the pieces might even be reusable after "landing" :) That Kress dumper looks interesting. It would be interesting to see someone provide turn and drive though a pivoting axle like that. Luckily it looks as though the back wheels don't steer. Quote
That_LEGO_Guy Posted October 10, 2015 Posted October 10, 2015 I was actually fiddling around with something the would function the same as that front drive unit of the Kress hauler, might give it a go after i finished my Morgan 3 wheeler Quote

Good old Lego builder Posted October 29, 2015 Posted October 29, 2015 I have a small question: I'm trying to build a winch like on the Unimog 8110 BUT with classic Lego Technic bricks. I borrowed a wormgear from my son, but now I can't have it meshed with an 8-teeth gear. (I'm not a technic mastermind). Is this possible at all? In Sariels book I saw an example with bevel gears, but I was wondering if I'm doing something wrong here.... Quote

You should be able to, like the first picture, left hand side here http://www.technicbricks.com/2014/01/lets-talk-about-gears.html Quote
Good old Lego builder Posted October 30, 2015 Posted October 30, 2015 Yes, with the current Technic beams I can, but with the old, studded, Technic beams I fail.... Quote
Lipko Posted October 30, 2015 Posted October 30, 2015 (edited) rotate the old beam with 90° (so it's vertical). I don't think you can fit them otherwise with straight studs-up build. Edited October 30, 2015 by Lipko Quote
AOW Posted October 30, 2015 Posted October 30, 2015 How small "independent" rear wheel driven suspenssion can be build with "classic" technic parts ? Those up to 1999? Quote
