Posted December 23, 20159 yr Hi there everyone This creation is similar to my last project (mini jeep), but in truck form. Nothing fancy, but I had a lot of fun making it. Specs 2x L Motors @ 3:1 1x Servo Functional Doors Working front lights 29L x 15W x 16H (chassis, in studs) 708 grams Thanks. Feedback is appreciated.
December 23, 20159 yr Looks super cute, and it looks so much fun to drive! The looks remind me of the Suzuki Super Carry that I adored as a kid.
December 23, 20159 yr Heh, that was the first thing that came to my mind when i saw it,.. only somesort of chopped up version,.. anyhow, cool thing :) me likes.
December 23, 20159 yr Very nice :) Maybe almost to fast for my taste - have you tried bevelled gears to get a bit lower ratio on these motors?
December 24, 20159 yr Author Looks super cute, and it looks so much fun to drive! The looks remind me of the Suzuki Super Carry that I adored as a kid. *snip* Thanks erelender. You're right, it's very loosely based on this manufacturer in truck form. Heh, that was the first thing that came to my mind when i saw it,.. only somesort of chopped up version,.. anyhow, cool thing :) me likes. Compact and powerful, nice work! Thanks Sylvian and Sm01 Very nice :) Maybe almost to fast for my taste - have you tried bevelled gears to get a bit lower ratio on these motors? Thanks Kris. Bevel gears are very easy to change to (20/12) but at 1.66:1 it's a bit too slow for me. This model is great fun to zip around the house. I just say popopopopopoooooo . I have absolutely no idea what this means, but I'll take it as a compliment. Thanks!
December 29, 20159 yr Author Cute it is, yet it is!!! Great work dude! What a fun toy! Thanks everyone!
December 29, 20159 yr Looks super cute, and it looks so much fun to drive! The looks remind me of the Suzuki Super Carry that I adored as a kid. On my first job I managed to crash into one once (whilst also driving another one [same model]) and it flipped over... the model is great - i love things at this scale but why not flip the motors and have one drive each side (no need for diff and better turning) great details
December 29, 20159 yr Author Thanks rockbrick! Flipping one motor is certainly possible, but there'd be gears on both sides, causing possible harm to the cables. Keeping all the gears on one side allows more room. Great idea though!
December 30, 20159 yr Author I just have a question for someone about gears. Which is the correct way to specify gear ratio? If the gears are 3x faster (24 gear to an 8 gear), is it 3:1, or 1:3? Sariel has it 3:1, but I've seen it the other way a lot too. Just want some clarification. Thanks
December 30, 20159 yr Well, I'm not sure about the convention but this is how I understand it. You chose which gear stands for input and the other is output, then the ratio is 'input turn':'output turn'. In other words, how much does the input need to rotate for the ouptut to make one full revolution. Of course, it's conventional not to use fractions (i.e. 1/2:1) so there is not always '1' for the output but you got the idea. Hence if you have 24 gear as an input, 8 gear as output, I'd say the propper spec for ratio is 1:3. Of course in this notation you talk about radial velocity ratio. If you have taken number of teeth as a unit, the ratio would be in reverse.

If you have taken number of teeth as a unit, the ratio would be in reverse. Thanks for replying kris. I don't have a mechanical mind so I struggle with this stuff. So I take it that my gear ratio (24gear to 8gear) is 1/3:1, which converts to 1:3. If it was the opposite (8gear to 24gear) it's 3:1, which converts to 1:0.333. So in other words I've been writing it wrong. Hang on, I just read that last bit again. If you talk about teeth it's 24:8, which is 3:1, but if you talk about rotation it's 1/3:1, which is 1:3. So for my model either one is correct. Confusing! Edited December 30, 20159 yr by Chade
December 30, 20159 yr Thats it. There is indirect proportion between radial velocity (rotational speed) and size (number of teeth). In engineering world, I think the speed is taken as aspect more commonly, because that's what you really care about in gearboxes etc. Anyway, the best is to clearly name what are your ratios related to (whichever choice you pick) so there's no confusion.
January 8, 20169 yr Hello Chade This is a very nice MOC that you have built. It is pretty fast and compact. There was a lot of fun to build it on. The cabin I've slightly modified to fit the proportions better, I think.

January 9, 20169 yr Wow, I am extremely surprised at the speed of that truck! I must get my hands on those new tires. Edited January 9, 20169 yr by DamonMM2000

Thanks for building and sharing! I'm currently building your classic car and it's a really enjoyable build. So, thanks for the instructions Wow, I am extremely surprised at the speed of that truck! I must get my hands on those new tires. 2x L motors @ 1:3 is pretty quick Edited January 9, 20169 yr by Chade
January 13, 20169 yr Author Nice little truck, well packed with fun. The video just made my day :) Thanks miguev. Glad you like the video, it's a bit silly :)
January 29, 20169 yr Hello Chade .... Here is my conversion to "Race Van" ... At such a fast Van naturally fit the spoiler better ... :wink: Here all pictures: http://www.technic-dialog.de/Homepage/index.php?page=24&album=2133 And here is the video:
