| MCR Pro, Motor, Pinion Help?
I am a total Newbie with 1.9 and need help finding the right motor and pinions. So far I had to return one motor (wrong size) ended up at local Hobby Shop with a Reddy motor, which has a too short arm shaft and had to grind on pinion to get some kind of gear mesh. I need a 12 and 13 pinion, but have NO idea on which one to order (shaft size/pitch etc.). Any help, links, info would greatly be appreciated. |

I'm sorta in the same boat, just received a Losi MRC Pro. Most brushed crawlers here run "540 cans" IIRC, the 1.9's run a "380 can" (can is the motor case size.....not BREASTS!!!!!). The 380 cans run a smaller diameter shaft, thus all my frikkin RC electric stuff (pinions) are too big for a 280 can output shaft. Ka ching, Ka ching....... I am not sure of the pitch, but a quick look seems to be a 48P......don't hold me to that. On this forum, look to the "1.9 class" forum and see what they are running.

Just returned a 380 brushed Traxxas motor, too long and would not fit into motor plate and mounting screws didn't line up, so not to sure about 380 size. The Reedy I just installed fits fine (except for a short shaft) and it is made for 1/18 scale and called a "Stump Puller" #290. Works OK except for the pinion problem, don't have full gear mesh. Pinions I see in sets, but to get what I want I have to buy 2 sets ($30) and don't feel safe buying individually, just not sure which one? |

280 is the direct bolt in size. 370 will fit with a little work to the motor plate. Both need pinions with 2mm shaft diameter, .5 mod pitch I run an Associated RC18T motor (~$10) in my MRC based scaler on 3s. Scoots pretty good, but the magic smoke comes out if it's bound up much. These little motors are fragile compared to the 540 sized motors. |

Ahhh Haaa, Manning, this is what I was looking for. Thanks... Now I can search with some confidence and can stop having to return items.

I just got my MRC Pro and cut to the chase with a Losi Xcelorin 18.5 crawler set up, used the included 15T pinion on a 2S and it works like a charm. (I have pinions from my RC18 and Mini-T.)

Mini T = 280 motor = bolt in, no mods RC18T = 370 motor = need to mod the motor plate a bit |

Losi's Insane motor works very well in the Pro. Pair that with a Tekin FXR esc and you got a combo with good drag brake and wheel speed that will last a long time.

The losi RX-280 motor from a mini-t works great if you gear it down to a 12T (stock is 14t). Cheap to.
