Sikorsky S70-C Firehawk (Delayed)
jwarner posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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.
