I am building a custom rc 1/10 scale crawler which will consist of a custom lassr cut chassis. 2 speed gear box, one for high torque crawling and one for high speed group ripping and mudding. This hopefully should be a mid ranged cost engineering marvel of a rc car and should be great hopefully, looking forward to having some great fun with this, making it and hopefully driving it in the next month or two!
Gearbox Work Part 1
Did alot of work on the gearbox but eventually ended up deleting 2 gears, realised that the shifting mechansim was just based on two little inserts that lock under the gear, silly me, under high speeds that will crack almost instantly, so i will implement the shifting tecnique they use in cars with teeth locking into other teeth
Lovely stuff!
Devlog #2
I (Hopefully) learnt how to use markdown
What I did today 😸:
•Today I finished off the cad designs by adding 3mm holes for where mounts and etc go for M3 screws (3mm)
•Now although this may seem like simple work i can assure you it was not, as i had to expertly place the holes in strategic places so it doesnt crack easily, So basically most time was spent procrastinating and evaporating as its currently like 28°c in the UK.
•Also kinda found suspension links shocks motor battery mounts screws receiver servo axles. But that will be submitted on the Github BOM later!!
-What’s next:
•Drivetrain Design (Gearbox etc)
•Add parts to the BOM, and properly journal (is this journaling???)
•Final simulation
•ASSEMBLY!!
You can find the laser cutting files if you wanna see them at: Project-Mud-Striker Github

What i did today 😸
today i did the basic cad designs of the side rails of the crawler (if you are not sure what a crawler is its basically a rc offroad expedition-y vehicle that has high toque and power to climb rocks and obstancles, basically a scale down remote controlled truck)
I realised after a while that the 12mm i had the chassis vertical width or whatever was far too small, and at high speed bumps, the aluminium/stainless steel will crack over time, decreasing the longetivity, so thats why i increased it to 20-25 mmon certain points, and even higher on joints and bends because thats whel most stress will be exerted. see below in red:
Whats next??
-Adding cutouts for links and shocks
-Designing drivetrain
-Choosing electronics: Battery motor reciever transmitter servos etc
-Assembling maybe!?!?!
