For my 8000th post, I'm presenting my model ideac for the TC30. I got the idea for the models by watching Bajd and Dakar racers, especially from the perspective of the helicopter. The same helicopter that records the races could also be used to provide support and rescue. One of the models will be a trophy truck with the following functions: Independent suspension in the front Live axle in the rear RWD with a fake V8 engine Steering actuated by a spare tyre in the rear Full interior with 2 seats and a steering wheel Opening doors and hood Monster livery Here's the current digital progress. I'm using the new large, thin tires and suspension parts to keep the model as compact as possible. The rear suspension uses a ball joint to attach to the rest of the bodywork. The angled spare wheels provides the HOG input. I am really proud of the following drive and steering solutions. The driveline basically goes directly from the axle to the fake V8, while the steering system uses linkages to transfer the steering input from the spare tyre to the steering rack. I think this is a more compact, and a cleaner solution than using gears. This being a trophy truck it needs some proper suspension system. Currently the suspension system is compressed a lot, so the physical should have a much higher gorund clearance. The front suspension is sharing a single shock absorber which is placed longitudally between the wheels. The rear suspension is an interesting hybrid of a ball joint and a trailing arm suspension. The suspension arms not only center the rear axle, but also act as levers for the suspension system, supported by hard shocks in the rear: That's the plan for the trophy truck, I will build and weigh it soon. it should just be under 300 grams according to the Studio. The second model will be some kind of a Rescue/camera/support helicopter which supports the race by providing video coverage and a means to a rescue if needed. The idea is to implement the following functions and features: Spinning rotors using a gear or a hidden rack trigger mechanism Collective control for the main rotor Winch with a ratchet mechanism Foldable landing gear Add lots of cameras, sensors, antennas, etc. Colorful livery, using neon yellow, red, white, black, etc. Modern styling with lots of curved surfaces Current progress so far is the basic concept of the collective control uisng a small turntable. Basically the central axle can move up and down and thereby change the angle of the rotors: So far that's all, I will update the topic as I go along. -
Friends, It took a little too long, much like the ATS, but the MD600N if finally done. Much more at thirdwigg.com, and the Flickr album can be found here. As I child I would see the MD600N and MD520N flying up and around my house. It was time to honor the love for the aircraft. The MOC has the following features: Opening Doors Working dual Joysticks Working dual Foot Pedals Working collective lever Swashplate Collective control (much thanks to Efferman for many components of the design) Swashplate Cyclic control NOTAR rotation Six bladed rotor PF L drive with LiPo Battery Working Landing skids (I mention this only because getting it to support the MOC and not tip over was quite a task) Seating for eight I hope you all enjoy.

It seems about time for me to get into the TC15 spirit. I've been building up a storm in my dorm room every chance I've had when I haven't been studying, and it seems about time I share my progress. I noticed that there are notably few helicopters so far, I think just steph's Chinook and Eric's Skycrane. So I decided to join the fray, and I'm going big on this one, the Sikorsky S-70C Firehawk, the cousin of the military Blackhawk. Unlike the blackhawk though, this one comes in pretty colors: Sikorsky S-70C - N2FH FireHawk by Christopher Ebdon, on Flickr I want my model to focus on playability, so I plan on making the swashplate RC controlled with PF. I also wanted to use as few motors as possible, so here's what I'm planning: 1 L motor - rotor blade rotation 1 M motor (or L motor if needed) - swashplate control 1 Servo motor - switch between collective, left/right cyclic and forward/backward cyclic So few motors means that the gearbox is naturally a beast, so it will likely be taking up the entire rear of the helicopter. Waiting on a few more parts to arrive before I share what I've concocted on that front. In the meantime, here's what I've been working on: Sikorsky S70-C Firehawk - WIP by jwarner1718, on Flickr I apologize ahead of time for the wild colors and stickers, my selection of panels is pretty slim so I'll be playing 'rainbow warrior' for a while until I have most of the design down. Easier to order everything at once right? Sikorsky S70-C Firehwak - WIP by jwarner1718, on Flickr Both cyclic sticks are synchronized using a few linkages. They will not be linked up to the swashplate movement, something I had debated for a long time, but decided that with the route I had taken with the gearbox it just wasn't feasible to fit it in. I guess this makes a fair consolation prize though. Sikorsky S-70C Firehawk - WIP by jwarner1718, on Flickr The battery box sits behind the pilot seats, and the fake collective lever acts as a pin that can be removed to slide it out. I'm really excited for this contest, hoping to finish in time and that I haven't bitten off more than I can chew. If I don't make it before the contest though I'm definitely finishing this one.

I showed this MOC the past weekend in the Lego Fan Weekend in Skaerbaek. After many cars and other land vehicles, now its time to build something different. This creation is based in the Russian helicopter Kamov KA-32. This helicopter has the peculiarity that it has two coaxial rotors turning in opposite directions, instead of the traditional main rotor with a small tail rotor. A real Kamov KA-32 used in Spain for firefighting. I have used the same color scheme. This MOC has been build in scale 1:16. The rotors has a diameter of 127 studs(102 cm or 40 in.) The fuselage size is 98x15x23 studs (78x12x18 cm or 30.7x4.7x7.1 in.) Both rotors are powered by only one PF XL motor and a PF Rechargeable battery. Complete rotors control using two swashplates directly from the cabin. Just like the real KA-32. Collective lever control: fly up-down Cyclic stick control(both sticks works): fly front-back-right-left(not turn) Upper rotor pitch pedals: turn right-left The controls only control de lower swashplate, and this one control the upper swashplate using the there grey links . The front wheels have free steering. And the rear ones have suspension, and a side sliding door. Very quick fuselage disassemble. I know that all this technical features and strange functions are difficult to understand. So here you have a video showing the helicopter working.
