  1. Thank you all for the tips and kind words. I will add this to my list of upgrades to get at some point. I'm not looking into adding a fan with all the air reaching the motor through the vents, but that motor mount will definitely help soak up heat and adds a bit of weight where it helps. Anyways, the new motor, ESC and bearing kit have arrived and I gave it a rip as soon as I installed those. The motor has a bit more power than the stock one, but it also spins slower, giving me less top speed. It is however advertised as a crawler motor so it makes sense. It also managed to stay fairly cool throughout a 10 minute run. I'm going to experiment with more motors as I just found this cheap surpass hobby 550 3 slot motor available locally that seems more speed oriented. I did not mention this before but I ordered the rally uprights from the M-05 and gave them a proper test in the mud. The car now has about 20mm of ground clearance, making it somewhat offroad capable. I did get carried away a little and left a few scuffs in the body. For those wondering, I will likely get another body for the shelf, as I made a couple of mistakes working on this one so I don't mind getting it beaten up. As for those tires in the front, I've 3d printed them. They're a 959 replica design that I found and modified and they'll need a couple more revisions before I can use them on the car. By the way, if anyone has suggestions for aftermarket tire options for m-chassis, I would love to know.

  3. Hello I am posting my first tamiya build, the Alpine A110 on the M-06 chassis. I have been eyeing tamiya kits for a while now but only just pressed the trigger on getting one. Building the kit has been pretty straightforward, just like legos but more advanced. My only gripe with the kit is the included crosshead screws can be a major pain to fully tighten up without stripping. I have tons of hex hardware lying around so I replaced all the regular screws with better ones. I also added shims everywhere I noticed play in the suspension components. The car feels very solid. I built the car with the stock bushings first, the bearing kit is on the way. I used some cheap aliexpress oil shocks I had lying around and a tamiya branded 1060 brushed esc with the kit motor. The servo used is a metal cased low profile servo from aliexpress I had planned for a different project. Now to make things a bit more interesting, I decided to pair the car with a 3s battery. As you might have guessed, it is not the best idea to pair a 2s motor with a 3s lipo, but it got me a staggering 47kmh (29mph) on the stock gearing. The car is so fun to just rip around on the road I cannot understate it. The brakes are a bit too powerful for this car so I ordered a hobbywing 1080 to get better control over them. The 1060 ESC takes the power just fine, but the motor got hot very fast and it got me thinking I should try to make it fast while keeping it brushed, as a challenge if you will. And so I ordered a hobbywing 555 11T motor, which is slightly longer than the stock one and should provide better heat handling. Have yet to see if it is any faster, as the specifications on motors are a bit confusing. It came time to paint the body, for which is used 3 light coats of PS16, 2 coats of PS30 and 2 more coats of some generic can of black I had lying around. Me thinking just using PS16 alone won't be dead accurate to the blue used on the real car. I think I got the result I wanted. Have yet to finish the decal work, just thought it looked so good I had to take pics early. More to come.
