1/12 forum

It's a unique part so I'll be waiting for parts from Japan. Just one of the joys of owning a weird Japanese chassis

Finished up the build tonight. fit and finish is really, very good. The shock is super smooth and the rear damper tubes are very precise (both stick and tube made from machined aluminum). I was just barely able to make 172mm width at the back with Pro-one hubs.

The Kawada FXIII is a pretty sweet looking kit. The owner of the hobby shop I frequent to here in Japan just bought one. The front damper tubes are really neat.
You can buy the whole front end assembly. So if you're looking to convert your front end to this style of dampening you can. Kamui rc in Japan has them in stock.
On Saturday, I went out to my local asphalt track and did a few laps with my new R12C3. I decided to run both my Kyosho and R12C3 to compare lap times ect. Before I even put any laps down, my preconceived notion was the Kyosho will be the faster of the two. Considering I've never put any laps down with the R12C3. The Kyosho Ra should be the faster of the two.
Running setup, same tires for both rides. The R12C3 was running a D3.5 21.5 stock 12.4 rotor and the Kyosho a ORCA 21.5 stock 12.5 HT rotor.
On Track
The Kyosho was obviously the faster of the two with a solid 0.300 sec lap faster than the R12C3 for obvious reasons.
A-I've been racing this chassis for 1.5 years
B-The Kyosho has the ORCA motor which is hell ass fast.
C-R12C3 was running bone stock setup and it's the first run for this chassis.
After laying some laps down I noticed how easy it was to carve into the corners and all the while maintaining corner speed with the R12C3. I felt the car was really connected with the track in every way - entering, mid and exit of the corner. With my Kyosho there was always this "grey area" or "disconnect" with the track. It just never seemed like it connected or responded with the track. Therefore, I was a little unsure about the R12C3 and doubted if this "connectedness" was a good or bad thing.
By looking at the lap times and the on-track performance I decided to make a few changes for the next run.
After reading up on Mark Stiles R12C3 suggestions on R12C3 setup changes. I decided to change the steering ankerman position by changing the steering block from 0 to + 1.0. I decided to increase the damper roll oil from 100 wt to 130 wt. I also noticed the motor performance was different between the two cars. So I decided to switch out the motors. So now, the R12C3 has the ORCA installed.
The R12C3 managed to drop it's lap times considerably. The extra bit of power and the setup changes made I was able to be 0.200 seconds faster than the Kyosho. I managed to gain 0.500 seconds! Pretty impressive for it's first day out. I can't wait to test and tweak this bad boy in order for it to go faster.
I love the front suspension design, many people at my track complain about how complicated the front end is. I personally like having the ability to adjust roll center, damper tube rates, droop.
All in all. I am very impressed with the R12C3's performance and handling.

Hi Edward2003,
It is interesting to read that you run 2S - 21.5T in Japan.
I tried to browsed the website of JMRCA, but couldn't understand the language
Is there any link to learn the JMRCA's 1/12 technical rules in English ?
In addition, any youtube channel for 1/12 races being run in JMRCA or TCS in Japan ?
TIA

what is the best center shock to use on a 12R5.2?
The standard ones bends the shaft far to easy!
I no everyone uses the hot bodies one, but no one seem to be able to get that anymore and the stoped production.
The vbc one looks nice but the ae springs don't fit that or the xray one.
CRC?
reflex racing team prime is never in stock either!
What's the go finding a decent shock that fits the AE springs???

Hmm...never bent the shock shaft of a 12R5. And I'd be one to do it!
Anyway, of all the shocks you mention, I'd say the CRC. It's readily available, builds up smooth, doesn't leak, and fits AE springs no problem. It's red, which may cause some cognitive distress once mounted, but there are drugs for that.
Pity about the Hot Bodies shock. It seems to be gone from global inventory.

this prime shock has been the best shock I have ever used on an pan car chassis very high quality very reliable , also loving the reflex front ride height shims they are black g10 instead of those ugly crc shims
