You guys have any suggestions on another motor? I know this really isnt thread specific but I wanted to see what you guys were running in your RB6s since its a little heftier than other buggies.

Id run a Fantom Apex (this is actually the motor I run). It is 100% as fast as my D3.5. Stellar motors. (look at the price, too)

None of the shurrspeeds or reedy sonics can keep up. Gear it 69/31 with the endbell timing maxed out, and run the Fantom 4500 shorty lipo. If you get your car to a reasonable weight, somewhere around 1560, you will have the fastest 17.5 buggy at your track.

I am building this part of the car now. My buddies set up calls for o* narrow. Do I simply switch the L and R to get the narrow setting? Meaning no flipping or turning, just a straight swap?

Exactly. Hole to the inside is for a wide track... hole to the outside for a narrow track width. (i think i got that right.. dont have the car in front of me).

I'd do a background check on your "buddy" before you used his setup.

I prefer the 4* inserts using the wide stance. But there's no denying those two guys are flying with the 0* narrow setup.

0* narrow felt super aggressive and overly twitchy to me. Tons of steering. But I'm just the water guy.

My 210 was pretty aggressive just not consistent. Maybe I will like it. You should answer your phone when I call. I don't care if you're out of town. I needed you and you weren't there for me

Not arguing but that doesn't make sense to me, If the hole is inside wouldn't that put the hinge pin/steering block closer to the bulkhead making it a narrow track ?

No easy way to explain but capts right. Ill try, inner on spindle means less material towards center of the car and more outwards, so that why increases track width.
