    Small pinion gear

    I want to gear down my Summit real low just for kicks - anyone know a Mfg of a 12 to 15 tooth pinion gear that will work? (I have a 55t spur gear i can use) I know they are 48 pitch but what is the ID and...?

    Seems a bit extreme... Isn't that like a 50 percent eduction?
    Not sure I wanna go that low but i guess it's not like I have to leave it.

    Yup, big jump down; but it is free besides the time.

    I think the smallest I have fit is a 16/50... you have to watch that nothing is interfering with letting the gears mesh properly too.

    Ive got my daughters summit geared as low as I believe is possible with a 550 motor (brushed). Its 17/55. With a brushless motor you could go lower but the limiting factor with the brushed is the motor hitting the RX box. Since the 380 brushless motor is smaller you could move it further down. If you wanted to go even lower you could always file a bit off the motor screw adjustment slot.

    FWIW, the lowest I have seen in 48p gears is a 15t and it was made my Losi. I bought 3 of them when I found them on ebay. Only have one left but they came in handy when the time was right. Losi makes really nice 48p gears. Beefy and wide like the traxxas stock gears. RRP pinions are more narrow than the traxxas pinions. I dont like that.

    so, all the 48p gears are compatible put aside motor clearance issues?
    I was not sure if the IDs were the same

    Most 48p gears are going to be for a 1/8 shaft. There are almost non for larger shafts. The spurs are obviously specific to the vehicle but any 48p pinion should work. Just keep in mind, RRP sells both metric and standard 48p gears. I'm not sure what the traxxas's vehicle need but you need to find out if your going to buy from RRP. Most other companies only sell the standard ones like what you need for a Traxxas.
