I see what you mean, but there is no challenge for me in taking something that is known to work and insert it into Lego. Technics was for me always something which always had a solution, but required you to figure it out. Ive been keeping an eye on pneumatic engines (2480 RPM is probably enough to hoover a bit), with the use of a high torque engine for some air pumps. Generally Im lookint into a 8 Air Pump/4 Engine pump combination. The only reason I need a pneumatic engine is for the rpm. Unlike you i will try to make some kind of helicopter, and the high RPM is perfect.

Interessting. What is also quite interessting is the PF Train at 9V, which has a very nice amount of RPM output and the Torque isnt even bad. Could be kinda interessting for an RC maiby?

Ah, I see. Well my Bad. I actually thought that the counterweight was one of these things that has a long cord inside of it, and those dont really weight much. But thanks for clarifing. Also, tomorrow Im gona pick up the Unimog. I can post a review or something along that if anyone wants.

Well from what I saw on the Video the ship lifts itself up, and the only reason for the string was so that the ship turns around and keeps itself from falling down with the momentum that it achieves by turning itself around. Well I dont know much about the Lego Engines, so yeah, I cant comment on that.

I saw some stuff about the implications. If you check out YouTube there is a Video of one of these planes with 2 engines that hovers up and then turns them to fly. Basicly he can hover with it an fly in circles. He uses 2 XL engines for it. The only real way for something made of lego to fly is using the hover method, as Lego pieces dont really offer the aerodynamics that is needed to fly. The thing would probably be made of 2 XL engines for the hovering, 1 M engine for the movin of back and forth(small rotor in the back should provide enough Power), and another engines, the smallest avaliable, for some kin of airflow regulator for the movement so that you could turn around etc. Not saying that its easy, just stating some theories Ive been thinking about.

Genius! I could really see this working off in a RC Car.

Thanks for all the replies! Well dont really ask me what I would plan on doing for the future... I actually would, most likely, try to build a RC car or something that could fly. Now, I really just need to get started, and as its not christmas yet, I can still get an additional set later :P But it looks like that I will get the Unimog.

Hello all together! I have always been a huge Lego fan since my childhood, but then trough school I lost touch with it. Now Im kinda tempted to buy a Lego set, because theyre currently on sale, and I wanted to ask about what youd recommend to get. Im looking for a set that offers alot of pieces that can be used for other stuff. Not only Power Functions, but also pneumatic. The only one Ive found is the 8110 Mercedes-Benz Unimog U400. The store also offers the 8043 escavator and the 8109 truck. Currently I dont min about the colour, because mostly Im just trying to see if I still got the same interesst in it as I had.
