Maks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingUH-46D Sea Knight US Navy (2) by [Maks], on Flickr Good morning. After 3,5 year hiatus I would like to present my newest creation. It's good ol' Boeing Vetrol helicopter, "the smaller Chinook", CH-46 Sea Knight. Here in UH (utility version) as used by US Navy in 60s and 70s. Here you can see the exact color scheme I tried to mimic: This model was almost entirely bulit during spring of 2017. But then DA came and I was unable to find time and motivation to buy some needed parts and finish it. But here it is, the big moment for this heli!

Zerobricks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingI decided to UP the things with my take on the 8081 modification contest. Here's what I came up with: Driven and steered front axle with homeage to the original design Tandem live rear axles working on a simillar prnicipal as the front axle Differential lock Two speed gearbox Working steering wheel You can see a sneak peek of the progress made in LDD:
colinrichardson posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingI started this project a few years ago but let it sit dormant. I've started it up again and figured it would be good to track its progress and start getting some feedback (though there's not much to critique yet). This is going to be a tandem helicpoter loosely based on the Chinook. I'm especially interested in mimicking the Chinook's flight controls and expect this to be the biggest challenge. The real helicopter's controls uses a sophisticated, for its time, hydraulic system to mix inputs from the throttle, stick, and pedals into outputs to the rotors so that it "feels" to the pilot that they're flying a more traditional helicopter. Though I briefly considered using pneumatics to create the control system, the lack of pressure variability made it an unappealing option. Instead, I'm working-out a mechanical gear and axle system to combine and actuate the controls. I may convert to an rc/servo system in the future, but plan on only motorizing the rotor's spin for now. The crude testbed / proof-of-concept mockup that I'm starting with. I'll upload some more images over the next few days.
