    Well, if you"re a Lego purest, Buwizz is a sin. You can use Pure Lego parts and use 1.6 volts Nizn in your Lego battery case and enjoy Buwizz like performance and still be pure Legoist. I've done one of the first true and the original RC high speed mods early this year for the Lego set 42093 and I've step it up on my latest mods.. Here is a video example of my Lego 42093 high speed mods from 7 months ago using the Lego battery boxes.. So don't listen to the devils and stay pure my friend .. :)

    Well, I went ahead and modified my small pickup and used the Lego 42093 43.2mm tires and boy I was wrong!! I was correct about the steering pivot and using the 43.2mm really kick butt!!! Beside being very fast , The 43.22 mm tires really perform well and it haves very serious grip for good traction.. If you have a model like the 42093 and you motorized it, if you dont change the front steering from the default setup, you'll experience power slides due if you turn to the left or right on full power. even adding weight over the axles actually help with traction. I can wait and see your mini 4x4 @Zerobricks ... ... this is so much fun!!! please check out my video! riding on 43.2mm tires.. Im a believer, now!!

    Yes , The corvette's pizza cutters do lack gripping traction but I can manage to have the steering pivot point almost half way in, you can actually push the steering pivot to the center but a little notch that sticks out that is in the rim (see picture 2 ) stops the axle of a full rotation!! you can cut the notch out and have full on center steering pivot point but half way is the best without mutilation!!! using the 49.5mm tires and rim, i manage to have the steering point past half way in and it also have the notch in the rim .. (maybe Lego group done that on purpose?) I just know that looking at your picture, the distance just a half of L more better then the stock 42093 steering pivot. I just know from trial and error that running in high performance, if its a racetrack that has a lot of short straight aways and a lot of curves on the track. My design can be useful in a handful racing clubs that uses short length pahs with alot of curves.. there seems a trade off from to much understeer on long straights vs to much oversteer on quick turns and handling.. using the Legos 42093 tires would be best for dragsters front axle since going straight would be the best for the small scales model!!! The current technic elements lacks the high precision required for small scales that we are designing on. the first picture is the actual 42093 tire and the steering pivot is almost half in. you can actually have the steering pivot point all the way in the tire but a little notch prevents you to do that.. maybe cutting it can curet that issue?? see picture 2 for the notch.. (its a 49.5mm wheel but the corvettes tires have the same notch) Lego technic steering by victormendoza_jr, on Flickr Lego technic steering by victormendoza_jr, on Flickr

    I had a similar issue with 2 wheel drive and it was the steering design was the issue. Moving the steering pivot closer to the center of the tire, in this case, my steering pivot was in the center of the tire and steering was spot on..

    Some more ideas to share with the Lego set 8081 suspension that I have designed and tested.. Its the same independent double wishbone setup with a limited Live axle support which the Lego 8081 uses but with wheel hubs to use the bigger tires and rims. The limited live axle is different from the Lego set 42099 4x4 Control+ which supports full live axle with independent on top of that. On the Lego 8081, when the front suspension hits max compression of the springs on the independent suspension, the axles then becomes a limited live axles that pushes the opposite wheel down or upward. On my set up I also converted the rear live axle to a full independent with limited live axle support and added AWD drive with 3 diffs. and a High/low gear to the fake engine. The transmission feels solid and very smooth to operate. i also have designs a removable rear shell so you can converts your SUV into a pickup truck. Just like the old 1970's Chevy Blazer's and Ford Bronco's.. Here are some examples pictures to click on and a quick video of the setup.

    You can even use a PC computer power supply!!! Red color lines on the pc power supply are 5 volts and the yellow color lines are 12 volts.. only thing you need to do is use a jumper wire on the power supply to keep it on!!!! Any power brick rated 9 volts should do , but buying a Lab/table power supply is kind of over kill!!!

    I've done many mods for the excellent Lego 42093 that are compatible to the Lego 42098 Blue car and these fine examples should work with a little adjusting to the Leg 42098 car chassis. Gives you guys and gals an idea on how much mods can be done on that small scale. First example , is a 4x4 mod to turn your car model into a 4x4 !!! or a race car with rear suspension. I could build the examples but I would rather wait till I get the real sets!!! :) https://www.flickr.com/photos/23813430@N07/47292915522/in/datetaken/ Lego Technic 42093 4x4 mod by Victor Mendoza Jr, on Flickr https://www.flickr.com/photos/23813430@N07/40303622703/in/datetaken/ Lego Technic 42093 2 x Lego L motors by Victor Mendoza Jr, on Flickr

    I think this shared video explains it a bit

    Just doing some more Lego Technic RC mods and this time I've discovered a Lego clone of the buggy motor called Monster motor from China. The idea of my model is to be small and light weight by designing a uni-body chassis based from the Lego set 42093. I'll have more on the design later but I would like to share a few videos for all ages to learn from.. Using the default Lego battery AA case, Im using Nizn batteries which are rated 1.6 volts but my measurements shows 1.8 volts!!! 1.8 x 6 = 10.8 volts!!.. almost like using a buwizz on fast mode or what ever you call it. Hooking up the monster motor fast output to an axle that drives a differential, I'm trying to figure which tires between the 49.5mm or the 56mm haves the better performance..The transmitter is a China 2.4ghz /IR clone of lego's parts My MOC sports a front 11 wide full independent suspension and rear semi- live axles. if you have any question please leave a comment or anything constructive. 100 percent Lego bricks are used .. The first video, the model is wearing 56mm tires and the second is wearing 49.5mm I plan to use 2 x Large Lego motors in the future.. I think they might perform better .

    The more I look at imdesigner42 model, I dont see a 8081 chassis when you look at the bottom view.. @johnnym your model, when I look at the bottom of your model, it does look like a 8081.. Can you please share on why imdesigner42 is acceptable and my version that haves a chassis 8081 in it is not??? We both are the same scale and size.. otherwise we dont have to build it out from a 8081 chassis as long it looks like it one?? very odd I think.. the smell of BS is strong so far...
  11. sirslayer
    Yes @alecmo99 thank you .. even though the body is different, the technic is still based off the 8081 and its all bolt on improvements !! @johnnym Mod is define as modification and technically and mechnicly i've max out on the 8081 and the next logical steps is the body shape is next. my second model on this thread is based off the original design and i thought it look like a fat pig (cactus picture) .. The 8081 design haves very good suspension and its a fine model. To be honest, I wish I have bought an original 8081 but building one from extras parts was almost good enough.. when it comes to design a modern 8081 to fit the year 2019 build, it seems like most of builders prefer to keep the old body design. RM8 did a different body design and it accepted but if i done a different smaller design, only a few accepted. @johnnym can you be honest and say your design would make a 2019 Car designer happy.. No , I don't think any of ours is close what a 2019 SUV should look like if you still to use the 8081 body.. The new Defender is different then the original and the 8081 of 2019 should follow also... The 13 l roof is the same as the 8081 and instead of fatten the body, keeping the 13 L roof width to match the body as best as i can trimmed off the extra fat and therefore the same seats and scaled is still the same.. who needs 2 1/2 L of space from door to car seat.. and if the 8081 is a real SUV in real life.. the real long doors and short hood and rear deck is odd looking beast. I don't this there is a SUV with long doors with a short bonnet ??.. it would look like a circus car!! and its a 4 banger!!! Only small truck in America uses a 4 banger with one exception !! side note: imdesigner42 is only 13/15 wide like mine and his is acceptable?? i smell bias!!!

    Is this more appropriate ? Lego technic MOC by victormendoza_jr, on Flickr Lego technic MOC by victormendoza_jr, on Flickr

    and I did post this a few months ago and @rm8 you said its ok..... and his friend says its ok.. I thought my previous version was a little to wide at the hips .. The newest version is based from this 2 month old design..and it doesn't look like the vette so don't go there. I like the idea of the contest to be on hold for the wait for a while to gain more attendance so I can upgrade the current build and having fun...

    The fenders from the Lego set 42098 Car transport would also work... and my model is in WIP after all.. The roof width is 13 L across, the body width is 15 L across and the length is only 1 L shorter then the original 8081, so adding a bumper puts me as the same size of the 8081 but the most important is the seats are the same size so therefore its the same scale.. using curved fenders and some extra touches really modernizes my version of the 8081. This is the only time to modernized the set and I really think its time to update the 1980's looks of the set.. :) Lego technic 8081 MOC by victormendoza_jr, on Flickr Lego technic 8081 MOC by victormendoza_jr, on Flickr download by victormendoza_jr, on Flickr Nissan Xterra

    Yes, its the same chassis!!!! Thirdwigg required red beams is in there and I shrunk the body and using modern parts.. The same chassis from the instructions .. The smaller body saves weight !! and this is the 8081 mod page!! and its an original design by me!!
  16. sirslayer
    There is another way to do this if you want to keep it simple.. First of all, you can purchase a 2.4ghz wifi China controller and receiver for a cheap price and you can use Nizn batteries rated at 1.6 volts each !!

    Here is another update of my Lego technic 8081 MOC pickup truck. This version is the Monster truck!!! tell me what you think!! https://www.instagram.com/p/B4fknZeHAzk/ https://www.instagram.com/p/B4fknZeHAzk/ https://www.flickr.com/photos/28224690@N03/49019328893/in/dateposted-public/ Lego technic 8081 MOC monster truck by victormendoza_jr, on Flickr Lego technic 8081 MOC monster truck by victormendoza_jr, on Flickr

    Here is an example of my 8081 MOC wearing 49.5mm tires and full support suspension. Front suspension is a Fully independent with limited Pendular suspension used in Lego set 8081 even for an example. Rear suspension is a 4 point spring on a limited live axle. Heavy sprung to support batteries weight. Recommend to use bigger tires size 56mm or larger. 49.5 is just for a basic pickup truck with no suspension. .. more on that later.... The motor in the driver seat is a Monster motor and ill have more on that later also :) Lego technic 8081 MOC by victormendoza_jr, on Flickr

    This Trophy Truck MOC is my version of the Lego set 8081 and its WIP at the moment and its motorized. I will plan to do a non motor version for the contest. This MOC has a shorter wheel base with 56mm tires and still using the original chassis from the 8081 and a Monster motor. Video is coming soon.

    Well any app can run the boost motor as a motor .. I wish there is a simple way just for the app to say "simple servo mode vs motor mode" I couldn't resist .. typical lepin pf servo from youtube.. and its very disturbing for any person that purchases this motor from Lego.shop and it doesn't supports its claim.. what a rip off..
  21. sirslayer
    No absolute zero??? Just like the Lepin PF Servos!!! Well, then I guess I have to wait till Lego's app supports Boost motors..

    Yes, I got my hub from the Batman Lego set and the default motors that it came with are very simple and it doesn't do the increments movement .. The motors I bought from Lego.shop website, part no 88008 named medium linear motor https://www.lego.com/en-us/product/medium-linear-motor-88008 Connect the LEGO® Powered Up 88008 Medium Linear Motor to the 88006 Move Hub or 88009 Hub to make your LEGO builds move with extreme precision. This LEGO® robot toy accessory features a medium-sized position motor for precise control, connecting wire and a connection point for LEGO Powered Up components. and using the Lego app or any third party apps, I can't figure out on how to or assigned the motors to do any precision movements.. it just spins fast like a normal motor.. does your app detect this motor and does it allow to use the precision part of the motor.. the app just sees it as a normal motor without any precisions controls!!! thank you for the follow up
  23. sirslayer
    I have a Powered Up 2 port Hub Hub 88009 and I have 2 x Medium motors and 2 x Medium motors with encoder.. All motors work and there outputs do spin .. It seems I can't get the encoded motors to work in increments with any app!!! Do I need a Control + hub to do the increments on the encoded motors??? or my regular 2 port hub should be fine??
  24. sirslayer
    Right on!!! its cute and children would learn from it.... Can't wait when you build a scale that does measurements of 0.001 of a gram!!

    Please @HorcikDesigns that is why I'm sharing these designs. :) I have a better design for the front axle that is closer to the original wheel base. They are in WIP at the moment but they are very close to what I expected on performance. The first picture is an example of the King Pin Inclination with the steering pivot towards to the center of the rims. With a straight inclination, the turning radius is being dragged by the tire and causing a bigger scrub vs a smaller scrub with the king pin inclination. a smaller scrub has less wear on the rubber and better handling on corners The second picture is the castor angle, where a positive angle haves better control of the tire when you hit a bump on the road.. with 0 degrees angle (straight up and down castor) the wheel haves less stability when you hit a bump causing it wheel to steer left or right after the bump and therefore less control of you travel of direction. The yellows arrows is where you can adjust the steering pins distance from the axles to provide adjustment to the center of the rear diff for more accurate Ackerman Geometry of the chassis to steering pivot.
