Dravpnir builds somthing Scale-ish with Performance
It is time to build a new Performance Scale as my old almost stock TRX4 is not up for the task anymore. The goal is to have it up and running for EuroCrawl 2022.
Axles:
The axles I will use will be the True Spider axles with axial OD/UD gears. I didn't like the stock options for the upper link mounts on these axles, so I have made some new ones. For the front they will be 3D printed and in the rear they will consist of 2 CF plates. I have also designed some weight holders for the knuckles so I can use tungsten rods instead of the stock brass weights that came with the axles. Much easier to adjust the weights in this manner. I don´t plan to run any weights in the rear so some adjustability in the front will be a good thing.
Chassis and Body:
I had a plan for the chassis, but then the rules changed and allowed more sporty-like chassis, so I changed my plans. I started with the SuDuOne FL and redesigned it so it fulfills all the requirements for the Performance Scale class. I also modified the chassis so it fits the Proline Cliffhanger body I will use for this build. I use a sway bar on my shafty and I like it, so I added a sway bar mount for this chassis as well.
The transmission will use Dluxfab SAF low ratio gears. The skid got a bit on the large side but the sides are beveled so the footprint is smaller than it looks. Perhaps I will redesign the skid later on. The bonus of a larger skid is that I got room to add a mounting plate for esc and rx behind the transmission. The battery will be mounted in front of the motor.
Wheels and tires:
The wheels will be 2.2 CF wheels with an offset face to be ok accordingly to the rules. The tires will be the narrow 2.2 Baja MTZ tires from RC4WD. I plan to start with the foam that the tires comes with and see if I need to change them or not.
Electronics:
I will use my standard Sanwa MT4 for rx/tx and a SHV800 servo from Holmes Hobbies. For the esc and motor I have not decided. I would like to test a Revolver V2 380 2000kv motor with Crawlmaster Mini V2 esc. If that motor isn't up for the task I am planning to go with a brushed setup with a BR Mini esc and a Crawlmaster Magnum Stubby 13T. For batteries I will use the same Nanotech 450mAh 3s lips I use for my Pro and Shafty.
