Hi I'm L, still mainly play with PF1 motor even PF2 has been released for now With the PF2(new electrical system that broke the old lego paradigm) PF1 motor are no longer likely to come out anymore Imao So I'd like to make compatible motor for the PF1 electric building system myself consider the proper shapes, specifications, and placement of the wires and while im making it, i wanna make it really good and nice to use, over lego motor to acieve it, I want to hear the user's reaction or wish. I look forward to hearing from your idea Question here 1. Which is more important (1) Torque(strength) (2) Speed 2. Size(Size and torques are in semi-parallel relationship) (1) 2x2(Micro motor size) (2) 2x4(S size) (3) PF Series's was fine, just need more torque 3. Shape (1) Round (Like XL Motor) (2) Square(Like Old Lego Motor) (3) Oval(Like M Motor, Flat Bottom Type) 4. Building type (1) Pin & Hole (2) Stud & Tube (3) Axle & Axle Hole 5. the unit of length (1) odd number(etc. 3x5x5) (2) even number(etc. 2x4x4) 6. Power Supply Method (1)PF1 (2)PF2 and last, I'm going to post it on the crowdfunding site if it's a good response after I've made the motor brick prototype. So what if there was a third-party motor with better performance? 1) If the performance is good, it can be purchased. 2) Because it is not Lego, it is not purchased. thanks for your asnwer and have a nice day~ and any critical, basic ideas are always welcome from L
First off, I would like to say that, no, I am not terrible at maths! All shall be explained! (Sorry, this may be quite a lot of reading!) The Back Story: First aspect: Some weeks ago, I was having a general look for sets that might be of interest to me. I stumbled upon a very good deal on the Lego City Bus Station (Set no. 60154). I decided in a spur of the moment purchase to pick up 2 sets, with no real plan… That’s what sowed the seed! Second aspect: In the not so distant past, I had purchased a huge Lego haul from eBay containing many train set items and accessories. In amongst this, was an incomplete copy of the Lego Freight Rail Runner (Set no. 4564) – (maybe 80% complete) – at the time I didn’t really know what to do with it. Over time I harvested the 9V motor, wheels, couplings, bogie plates, wagon parts and straight track – basically all the good stuff! Now, I’m a big fan of seeing people doing set combining! I have never seen anyone attempt something like this! (Correct me if I’m wrong!) The Hypothesis: “Is it feasible to make a decent looking locomotive of any kind, combining Sets 60154 and 4564? – Using minimal significant other parts, but in cases where necessary only using parts I currently have, and not resorting to ordering things. The locomotive should ideally use Power Functions with 2 motors, lights are not necessary. Also, the finished model should be sturdy, strong, and able to be played with by children.” Answer, Was It Possible? Yes, and in my opinion, it turned out rather well. What I attempted to build was a massively simplified Class 37, with much artistic licence! Here is the finished product: Thus, the idea for “60154 + 4564 = 37?” was born! What do you think? Any questions, thoughts, or criticism will be much appreciated. Regards, James :)
