  1. OK, try into some contribution to this interresting topic. I alway begin by shaping the overall model in real life with real parts. No care of any functunal aspect at this moment. This milestone allows me to evaluate the real free space into the overall model in wich i can place mechanics. Then i define a strategy, wich results in the main choices. Motorized or not? Place for the batteries? mechanics or pneumatics? All functions motorized or some of them manual? etc.. Next come the second step. This step is made using the first mocup that still stay build. The reference model is usefull to keep proportions, main form, etc.. In this step i usually place the main functionalities as direction, suspensions and essentially, when concerned, the gearbox distribution. The following step, with the previous model still build, consist in a full rebuild of the model trying to enhance each and every aspect as look, proportion, technical efficiency. This step is the time when a strong optimisation of al aspect is done. I do it in this way because it is at this third step that i begin to have in mind all the specific constraints of the model. Then : Repeat of the previous step as often as neccecary until i state the model is finished. Nota: Potentially, a model never finish... You can have a look et my katana supersport topic as a reference of my explaination. The process is clearly illustarted. KATANA SUPERSPORT Have a nice build!
  2. Congratulation to the winner! I am happy with the concept that win this compétition. A brillant idea well executed ! On a personal pov, I am fine with my result. Now I am impatient to see next contest!
  3. I do vote. I fond as well this should be mandatory. BTW when will be the vote closed?
  4. Agree with @Seasider curious to see how many people have voted. I find that the vote process has less visibility. Maybe a banner at the top of the topic listing?
  5. This is the second model that fits the sprit of the contest in my opinion. Would have kill to buy this in the 90' Well done!
  6. Not sure that the width of it could make it compatible with my station? The only way to know it is to build it, True? I'll try to do so this evening Because i found this build in the right spirit of this contest and becaus i like it
  7. Entry of steph77: POLAR STATION 8680 MKII Building of a play set based on the 8680 official set. Summary of the functionalities: - RC -Simplke and logic organisation of function to play with, - Drive, steering, front ramp and liftable deck motorized by two medium motors - Modular build - Lots of accessories as ULM helicopter, sleigh, rope, technic figurs, skies, etc - Lots of openable elements The video: The discussion topic:
  8. [TC26] POLAR STATION 8680 MKII This is the end result of my work on this contest project. Concept I do pass the last ours on this contest to optimize the build but also i tryed to have a complete reflexion on the concept. The main modification i introduce in this last iteration is the notion of a front and a rear end to this polar station. Thinking at it, it appeared as a non-sense that once the front door is closed, it was impossible to drive the machine as it was impossible to look frontwards...quiet dangerous to drive. Even like this, i mean after adding a piloting area in the front, sometimes unexpected things happend... The concept is based entirely on the memory of the exceptional playing quality of the original set. From then on, I focused on the realization of functions and accessories, all coordinated with a view to obtaining the most complete gaming support possible. For example, I installed a winch under the lifting platform at the rear. This winch enables objects to be loaded from the ground onto the low floor of the polar station. These objects can then be transported on the roof or inside the station. I paid attention at every detail i could. As an exemple, i wondered about the cable length of this winch, for example. By choosing a very long cable, once the rear platform is in the up position, this cable can be deployed across the station, and the helicopter or train can be winched up the front ramp. These are the whole accesories embeded in the station - an u.l.m. helicopter - a sleigh - a camera and two accessory boxes - two pairs of skis and poles - extra rope - four seals - a tool kit, always indispensable in the far northern Overall view of the model: From the technical realisation point of view. The build is modular. they are threee principal parts: - The undercarrier, - The station's floor - The upper body. Lets have a look at the undercarrier who is the most technical part of the model as it received the main gearbox that power the two upper structure functions and the propulsion and direction mechanism. The gearbox is a dual clutch one. The two clutches move together and it results in a two couple of functions that are grouped like this: - Direction and propulsion - Opening ramp and lifting deck This setup is the best combo i find to optimize the gaming experience. The two medium motors are located on the two outside ends and they are RC commanded based on the power function system. This offers a physical command that is absolutely mandatory in my mind and in the present play set build. The model is also colored as it is not strictly symetrical. The tracks are the small ones. These tracks offer a way smoother run on flat surfaces. Speeking of this, the station is 4X4 powered, but it has no crossing abilities. I made this choice in order to have a reliable build. The steering radius is quiet good without beeing exeptional. The model embed the crab drive possibilities, by moving the 24T black knob visible on the upper axle on the picture below The undercarrier is very sturdy, all mechanism are packed into frames and they are no cracking gears here. Viewed from the top, the main structure is visible with the use of oblique support beams. The rear deck lifting is build as it is visible below: The rotation is transfered from the gearbox to the lateral side where it will be transfered to the roof and it's linear actuator. I tryed to used as many differents building technics to transfer the movement. The original set used pneumatics, worm gear and racks. I made use of worm gears, gearboxes, racks and gears, originals 90° gear orientations, clutch gears in original use, etc... The final room inside ended as very limited, but i managed to squeeze all the functions in a very efficient and clean build. Some other views of the finished model: openable roof for easier acces: lateral door and ladder Pilot place and extra rope I hope you enjoyed it. The madatory video:
  9. Tanks. The HD video is uploading. I'll replace the 360 dpi as soon the hd is online. edit: done
  10. Yesterday build session wasn't that productive, However i managed to realize some things. First, i finalized the direction system. As it is motorized and use the standard racks and gear system, i had to insert a clutch in the power line. I finished wit a solution with two clutches, (the new ones - inline clutches), one for each steering racks front and rear. I add a small knob on the outter side and managed so to realized a build in crab mode for the direction. You can actualy turn the gear and the tracks will steer manually, place theme in a crab mode and have fun. The reset is automatically reallized if you let the motor turn, the two pairs of rack re-align due to the and-of-course clutches. Cool function. Second i had a look at the little helicopter wich is now sturdy and fiabilized: Third, i relocalized the battery box for more convenient acces and begin to search a solution for a proper integretion of leds. Some night taken pictures, (sorry for that) the heli: The battle field late night: And as i was working on the station, the crew has begin it's observation work of the environnement:
  11. :) maybe it is the original Set who has affected my building skill later. Who knows. BTW this helicopter is the subject of this evening build session. Thx
