When I first got these arms in my hand I was a bit baffled. They looked like a re-issue of the arms that were already available. So, how could this be something new and how could new arms gain length of the RC18(x) overall? And, for those wondering, I call them 18x’s as the 18t, 18mt, 18b, and now the 18r, are all generally the same platform. I saw the pictures on the FFRC web site and had to try them out for myself.

The new FFRC arms allow you to do two things. The first is to give the truck an extra 1/2 inch+ of length. Lets face it. A 1/8th scale is designed to go 60mph but a 1/18th scale is not. Having the extra length could enhance control at high speeds. The second is to allow customizable shock positions from the back to the front.

Initial impressions:

The first thing that I did with these arms was to place them next to the old arms on the truck. They are the exact same dimensions as before. However, by flipping the arm around, you will then gain the length that is advertised and you will be afforded new shock mount holes to mount the shocks in the front or the rear.

Of course, the quality of FFRC was still there. All the machining was completely smooth and brilliant. The product also appeared to be as durable as the previous FFRC arms that I owned- which is a good thing considering how much I crash into the baseboards of my house while chasing my dog (he hears the mamba arming and knows that its playtime).

Installation:

Installation was quick and easy. Simply remove all four tires, the set screw and pins to the hubs and casters, the bottoms of the shocks, and the screws holding the front bumper and rear pivot block. Slide the old arm off, slide the new arm on, re-install the above, and then lengthen the turnbuckle a few turns. Installation took 10 minutes for all 4 arms to be installed and another 20 minutes for all the turnbuckles to be re-adjusted.

I personally did not re-adjust my turnbuckle lengths and so far… so good.

Also, there were some worries over after-market bumpers. The RPM bumper will work with this upgrade. Mine slightly rub but it will not affect performance. If I wanted to I shave off 1mm off the inside corner of the bumper and have no contact of any kind.

Testing:

The arms performed outstanding. There really were no issues on durability or use at all nor were there expectations for them to arise. These are basically the same arms that I had on prior only flipped. So, the same quality is there. The RPM bumper and the wheels protected the edges of the arms from being hit. That was my only real concern as they were no longer covered in in the front.

I tried the arms on the street, in my house, and on a waxed surface for drifting. The biggest difference in performance was noticed on the street. On a 8000kv mamba system with a 2 cell 30A apogee lipo the speeds can get fast but the wing tends to hold the kit down. The fun doesn’t start until the 3 cell Apogee lipo came out. I actually did have more stability on one gravel part of the road and the 18b handled a lot better on the faster, more extreme speeds.

Conclusion:

1/18th scale RC's were designed to do 20mph and not 60mph. When they start to approach these speeds they tend to be very uncontrollable. This upgrade easily solves some of this without having to upgrade everything on your truck. If you are looking for new arms, look no further. You have the option to extended, normal, or half and half on these arms. So, why buy the old when these arms give you options!

If you are a lipo and brushless user, and want more stability, then this is your answer. Remember, these things were not designed to handle, or achieve, the extreme speeds that BYT users have been placing onto these kits. They have need to be upgraded to handle what we throw at them. Upgrades ranging from MIP Super Diffs and CVD's, a full compliment of FFRC upgrades, and a Mamba kit on lipo. No one has factored stability into the equation to re-engineer stability of the chassis. These arms attempt to do just that without major modifications and ease on any budget.
