RCC Addict
Well, I've finally been talked into taking my 1.9 MRC Pro and converting it to a scale class 1 competitor in my local club. After a little thought (like it was getting used anymore anyway???), there was only one build that came to mind. I have to have it my way though...
Currently just mocking things up, but it's coming along. Bending up chassis rails after ordering the body are next on the list. Problem being, cash is tight now. Please be patient with me through what is about to be one of the slowest builds I've ever done.
For now, I'm gonna copy and paste from my facebook. The descriptions below them will tell the story so far.
My builds always start with an idea I haven't seen executed, or a way to clean up an existing idea. A 3 link with a panhard in the front is something I set out for on this build, as I have NEVER seen one on an MRC based build. I simply draw my brackets in 2d on graph paper, cut them out, tape them squarely on to my medium, transfer the draw to the aluminum with an exacto by cutting them out, then get to it with the hand tools.
After rough cutting the brackets you've got a LOT of hand filing to do. I actually prefer to rough cut with a hacksaw, leaving generous material over my intended design. Doing so makes it easier to file them to the finished shape without screwing them up.
The front 3 link bracket. The nubs under that plate will be trimmed down level with the top of the housing, leaving plenty of room for the panhard over the top. Yes, there is only one upper link.
Trans cover will stay on the rig this time around. No dirt needed in my billet spur or pinion thanks! Trans is also built with HR billet gears spinning MIP CVD drive shafts. The front axle is over-driven with a mini E Revo pinion as well.
The rear 4 link bracket. Once again, this bracket will be slammed down on the housing. The links are only temporary. My new plates are actualled drilled for M3 rod ends.
Anticipated flex with shorter modded Mini Late Model shocks. This is also a guess on skid height with flex.
Skid height at ride height. These side plates are actually loaners so I can figure out my link geometry. Look for a full c channel chassis soon! The wheelbase is also a little long with my Pro links. The wheelbase has to be shortened by around 20mm still. The chassis end of the upper links will also drop about 8mm to match the lowered link plates.
Billet knuckles, C hubs, stainless M3 hardware, brass kingpins, CVs, and the whole bit. It's a shame I am taking it all off for LCC axles, knuckles, c hubs, and lockouts in the back. All of these parts have around 4 runs on them. The new wider LCC parts will also allow me to correct the scrub radius of these axles, and appreciate a little more strength. I don't plan on being nice to this rig.
A spare housing and some shocks... These are the mini late model shocks with the ends modded for MRC rod ends and caps. Around 1/2" shorter total length, but only around 1/8" less travel than the MRC shocks with 6mm limiters installed. The red marker lines correlate to the piston inside each shock, and the oil is written on the body inside the spring. Medium mini t front springs with 40wt for the front, softs and 35wt in the rears. This rig as a scaler will be VERY forward biased, thus heavier oil and springs in the front. This will be a very controlled setup with just enough travel to get the job done. Oh yeah, 3s on my Mongoose setup ought to help...
An example of how low the posts on top of the housing will be cut down. If it weren't for the fact that I want a panhard over the axle with a 3 link, this wouldn't be necessary.
Rebuilt and ready modded mini late model shock in my hand, 6mm limited on the axle still. You can see the difference in length, though the travel is within 3mm of my old shocks. Short shocks will keep my rig low, keep the shocks at a scale place in my fender well, and not limit travel too much. Just enough to get the job done.
Mockup panhard. Will end up MUCH shorter, much lower, and my link mount plate will be lower and NOT in the way.
This is pretty standard for a Samurai MRC build. Chassis mounted steering ideas in the works. Need the chassis done first.
The only other parts that remain from my comp rig are the ESC/RX. I also picked up the Axial waterproof box for the RX. Most of the electronics will be in the nose of this rig.
4 runs on those Ti chassis plates, and they're just spare parts now...
