    Excellent work! Any chance of showing the reversing mechanisms in action? It seems very quick and effective.

    Good gravy, I'm impressed with the speed you build at. Did you do a (partial?) digital build before starting this?
  3. BusterHaus
    Wow, this will keep you busy for a while. Isn't the whole upper arm built off the model? Have you started planning how to attach it?

    I am seeing a few topics attempting to set speed records. I remember a speeder with many (4? 8?) Technic 9v motors that reached over 40km/h. I think it was a studded construction. I can't find it anywhere - does anyone else recall it?

    Looks good! The battery box is used perfectly.

    Nice execution and a very cute result!

    I wouldn't hold my breath. They had a chance to do use black elements in the Porsche and went with the regular colors instead (blue pins etc). This was in a licensed product, where looks would seem more critical. Oddly enough the Exosuit set used black 2L axles, which makes theories about color choices made by TLG harder to establish.

    @mattthewise Nope, most of my Technic sets start with 42xxx.

    @mattthewise Thanks, I enjoy making them. I may get the 42053, it's not very expensive around here. I like the medium and smaller sets for C-Models as they offer more of a challenge because of the limited part selection.

    I don't own a 42053 set, but @Nequmodiva made a very nice Cherry Picker. I started making a windmill with 42055 but I doubt it will get finished. I pilfered too many parts from that set for other builds and don't feel like sorting 3,900 parts to continue.

    Forgot about this topic! Timely bump, thanks. 42061 C-model - Helicopter:

    @kbalage Very good work, thanks for showing the process - it's fairly simple but the results are terrific.

    The building techniques you used in the Hammerhead really stuck with me - Pythagoras triangles, connectors attached to angled beams, etc. Building with triangles is a very fun process, and the results look good and are strong. I've been designing a car for the past few weeks using the same building method and decided to apply it to this C-Model as well. Thanks!

    42061 C-Model - Helicopter The focus of this build was rigidity, functions were secondary. Instructions: http://instructions.busterhaus.com/42061_C_Model.pdf Functions: Main rotor and tail rotor are linked. Bucket can be tipped using a linear actuator. Opening roof can be used to lock main rotor in place, allowing ejection seats (not included)

    Hello and welcome! Great job reusing the attachment parts to build a new one, it looks robust and very functional. I like the linkage mechanism for lifting the side blades. Keep up the good work!

    Heh, I finished the instructions for my 42061 C-Model over the weekend, I will try to post them today.

    It's very close to having the axles aligned, but the gears are not in line. The motor or the link to the steering rack would have to be off center.

    @Didumos69 You can make a brake for the winch pretty easily by adding a ratchet-type lock. If you position it properly you can lock it in both directions. Here's an example:

    I think you'll be fine driving it directly, I had the same question a while back and used the servo with limited physical travel, without any damage to the motor. I tried gearing the servo down but it was a pain in the neck because the axle of the second gear was never aligned with the first, resulting in a car that never drove straight. Maybe there's some magical gear ratio that fixes this issue, but I don't remember finding it (edit: 3 gears will do it, but it takes space). The only alternative to gears is a linkage system, but that will increase your build size quite a bit.

    I tried the white connectors during my initial build and I think the second solution may work. These connectors offer too much resistance and don't allow the sliding ring to travel far enough to engage the red gears. You need to over-travel the catch (maybe by 10 degrees?) and then come back into the 90 degree position with it. It's much easier with the new smooth connectors. While I was building a version of the Porsche gearbox with your 90 degree limiter I thought about replacing attached by the rubber bands with and using the torsion of the axle to lock the position in place. If I remember correctly a test build worked well enough, but I went with the rubber band method to always have contact with the #2 connector.

    Great work, it looks very original and has plenty of functions.
  22. BusterHaus
    Very cute, instructions should take less than 4 months this time.

    @TinkerBrick The motors are side by side in his build, so the output from the drive motor is offset. The pulley design is actually not great, as the 3L axle is offset from the center of the motor by half a stud. I put it together quickly at lunch, I noticed the error just now. It will have to be driven by gears on the right side of the red connector, and the motor shaft cannot pass through piece #15100.

    @Appie Too bad they won't fit - thanks for checking, I don't have access to them at the moment. I guess the solution is to have it gear driven.

    4L wide compact differential: You need a rubber belt to join the two pulleys. A regular rubber belt will not do the job here, it's too wide and will rub against the 5L half-beam. I think the old square-cross-section belt should be ok: Bricklink: https://www.bricklink.com/v2/catalog/catalogitem.page?P=x137#T=P&C=11 If you don't like the pulley solution you can put a couple of gears on the right-hand side of the red #2 connector. I tried to keep the length as short as possible.
