PKW Posted January 14, 2015 Posted January 14, 2015 hi to all! this will be my entry for the TC6! I hope I success to build it as I want and I don't fail to build this MOC, it is a truck took from the videogame Motorstorm:pacific rift, I want to test my ability with my first scaled MOC and also, as I love to do, putting some strange and complex functions into a small creation :3 those are the four function that I've planned: -1 buggy motor for drive (4x4 with two differential) -1 M motor fot 2 speed gearbox -1 servo motor for fron wheel steering and.... -1 L/XL motor for boost function, with overcharge system (it is reallly difficult to build into that creation) the points where I'm focused are: -make a reliable chassis with 4 link suspension similar to the molotov baikal one (the "real" type of suspension is impossible to build due to the start from a videogame, it doesn't respect all the physics rules ahahah) - make a llimited-lifetime boost function (automatic slow recharge) like the game, with a brake function if it is overloaded (in motorstorm cars explode but I can't replicate that :'( ) -finish this moc D: i'm not an expert builder but I love if someone could restart this project after my try those are some pics of the molotov baikal, i have to built it in yellow and with gray wheels but i hope to make some stickers for the black and red painting photo took with the in-game photo mode this is my first try for the chassis, unfortunately I don't have 4 9m uniball link but it looks more similar to the molotov baikal system i've made some improvements and also tested the gearbox that works quite well, i'm only worried about the boost system and the truck cockpit suggestions, impressions and critics are welcome!

Milan Posted January 14, 2015 Posted January 14, 2015 Nice progress so far. what is that boost function with L motor? One correction: it cant be 4x4 if it has non-lockable differentials. Right now, it is awd :) Quote
aminnich Posted January 14, 2015 Posted January 14, 2015 Looks like a good start sorry to be off topic, but wow we have seen a lot of different mocs from you in a short amount of time. Nicely done Quote

Right now, it is awd :) if i'm Not mistaking My truck doesn't have lockable dofferential, however thank you To have taught me a new thing, i don't know that difference in The game Boost upgrade speed an acceleration forse a limited time in you use It while is overloading your veichle Will explode :3 due To The lack of Power in The 2nd gear, gearing up and connecting a L motor To The buggy one is possibile to increase speed and acceleration, but I also want To limit Its lifetime with a mechanism that I'm still perfecting in My mind :3 Edited January 15, 2015 by PKW Quote
pint14 Posted January 15, 2015 Posted January 15, 2015 The truck looks great, but am i only one who thinks that those wheels are too small? Quote
5imon Posted January 15, 2015 Posted January 15, 2015 Interesting truck! I'm very curious about what this boost function will be and how it will work. And I agree with pint14, I'd use some more impressive wheels for this type of vehicle, like Unimog or balloon tires. Quote
PKW Posted January 15, 2015 Author Posted January 15, 2015 (edited) The truck looks great, but am i only one who thinks that those wheels are too small? yes you're Right wheels are 1 stud smaller than what they have To be for a perfect proportion with The length but when The aesthetics Will be finished They won't look Small Interesting truck! I'm very curious about what this boost function will be and how it will work. And I agree with pint14, I'd use some more impressive wheels for this type of vehicle, like Unimog or balloon tires. I think you know how much is bigger an unimog wheel than those one, and is impossibile for me to make an huge building due to piece limit but also for power limit I'll make the boost function after finishing the bodywork, it has to fit inside ;) Edited January 15, 2015 by PKW Quote
NXT45 Posted January 15, 2015 Posted January 15, 2015 Nice MOC! What other 2 functions do you think you will combine in that? Quote
PKW Posted January 15, 2015 Author Posted January 15, 2015 news from the chassis :3 I've made a better gearbox (but sure not the last version) a better steering axle, it has some play but during the drive it works really well and with a plausible steering range also the first item of aesthetics, this could be useful to decide if I have to make a shorter chassis and this is a view of the complete chassis Nice MOC! What other 2 functions do you think you will combine in that? there are written ;') boost function and 2 speed gearbox Quote
Milan Posted January 15, 2015 Posted January 15, 2015 if i'm Not mistaking My truck doesn't have lockable dofferential, however thank you To have taught me a new thing, i don't know that difference If you say it does not have (you did not put option to lock diffs), then it is regular awd. 4x4 means simply that all four wheels have same speed and same torque (all three diffs are locked) I like your idea for a boost! :) Quote

Milan Posted January 15, 2015 Posted January 15, 2015 Hope you will be able to construct that :) Good luck! Quote
PKW Posted January 17, 2015 Author Posted January 17, 2015 i completed the cage for the cockpit, but I'm worried about one thing, although I'm quite optimistic To acheive to build a great bodywork, I'm not dure if my boost function will work, testing this MOC I've seen that the gearbox works well but also that the power used by it make (for example) impossible to shift down the gear when it is not moving, I don't have the lego original system for gearboxes and I need To move To shift gear but in the second gear the buggy motor, combied with the gearbox motor use al the battery power, si I hope that turbo won't stole all the power that he use To power up the buggy motor, or I need an other battery box and the Weight will be too much (I'm using the lipo battery box but I don't know if it is tired :') ) also I'm not very sure about the cage, but i've used all my red piece To do it and I can make a better one only in black D: Quote
PKW Posted January 18, 2015 Author Posted January 18, 2015 Hey! I've finished the bodywork, What di you think about? Is really hard for me to build realistic Lines To emulate the molotov baikal, but this has a really funny shape :3 The the battery of my iPod died so I decided to put another detail :') Please tell me your opinion, expecially if it isn't good ;) Quote
LeocornoProductions Posted January 18, 2015 Posted January 18, 2015 It looks realistic to the real version, but if you want to go the extra mile then I think stickers will complete it Quote
cgg199 Posted January 18, 2015 Posted January 18, 2015 Great idea, and I like what you've done so far. I would recommend covering the hole in the bed and the buggy motor by putting the box in place behind the cab. Also, I would try and make the role cage fit the cab slightly better just to neaten things off. If you want to go the extra mile, add small things like openable doors, that just enhance the model that little bit more. I really like what you've got so far though! Quote
aminnich Posted January 18, 2015 Posted January 18, 2015 looks good, but if I may give recommendation. Build the cab first, then the roll cage. It will look better trust me. Doing it this way will also allow you to build the cab more like the original truck. Happy building! Quote

If you want to go the extra mile, add small things like openable doors, that just enhance the model that little bit more. I really like what you've got so far though! thank you! This is my last process, i've added the mirrors and the motor cage, now the cabin is 1m more o long and the cage 1M shorter than before, i can't make openable doors due To the small scale and I have to fit into the cabin the boost mechanism and the receivers, taking about the cage if you see the photo its measure are taken by the wole truck, and it has not to touch the bodywork so 1M is the smaller distance, also i'm using angle 5 (67,5°)connector To fix the cage to the motor cover (not finished) only because i don't hav angle 4 (45°) red connectors :( and i need to modify the steering or find some piece that are shorter than the 5,5M axle with the stop at 1M PS: it is really funny to drive this truck and use the 2speed gearbox, it only requires big space to reach the highest speed, like its "real" brother molotov baikal ahahah Edited January 18, 2015 by PKW Quote
NXT45 Posted January 18, 2015 Posted January 18, 2015 Wow nice creation! I will definitely vote for you! When will you post a video? Quote
PKW Posted January 18, 2015 Author Posted January 18, 2015 Wow nice creation! I will definitely vote for you! When will you post a video? Ohh thanks, but it isn't finished ;) i completed the aestethics only to see how much space I have to fit the boost mechanism, and I have to see if the battery box are enough powerful to power the RC motor and the L motor ;) Quote
cgg199 Posted January 18, 2015 Posted January 18, 2015 That looks a lot better now. I really think that's made all the difference. Keep working on that boost mechanism and it'll be fantastic! Quote
PKW Posted January 22, 2015 Author Posted January 22, 2015 (edited) This is the final version of the gearbox, due To my 3M clutch is is really fluid and it doesn't use too much power To work Those are some photos of the clutch hope they will be useful for you But I have a bad new, I'm nera ti fail this MOC :( Edited January 23, 2015 by PKW Quote
PKW Posted January 23, 2015 Author Posted January 23, 2015 The reason why I'm near to fail this MOC is one, really simple, and called: thermal protection Searching in philo website I've found that all lego battery boxes have a thermal protection (that don't Let them give to motors/receivers more than 750mA/h) this is a bad news because even if the v2 receiver could power up one L motor and one buggy motor togheter (normal propulsion+ boost) the battery box cut out its power after sole seconds, this Could be useful To make an electronic overcherge of the boost that acts like the motorstorm one, but... The boost in that small amount if time hasn't enough power to speed up the truck, after different gearing tries i've definitelly left that mechanis. So those are some options that could save this building, but I need some help and please suggest whatever you want! 1) a subtractor mechanism with two L motors (reduced speed but it could work, and I think I could make the autobraking system when "overcharged") 2) buy another battery box, by the Weight will be too high I think and also lipo battery are expensive 3) and old 9v motor move a switch that control the L motor powered by the old 9V small battery box (more weight and without an autobraking system) Quote
Epic Technic Posted January 23, 2015 Posted January 23, 2015 Number thee seems like the best choice, please save this project cause it's awesome! Quote
