    Pull start question

    i just got a new obr 31.8 full mod and the compression stripped the paws on the pull start after I started it 4 times. I don't wanna keep having to order the paws for it. Is the turtle racing pull start worth the money or is it going to have the same problems?

    New OBR 31.8

    i just put a new OBR 31.8 engine in my losi, I was just wondering if it should be really stiff when you first start running it. I no it should be stiffer due to higher compression but I feel like I'm gonna rip my arm off when trying to start it. Is there anything to do to fix it.

    OBR Widowmaker 38 post break in.

    Got the 38 all broke in nice, the victory pipe is sweet, it's loud but with the Turtle Air filter system with the baja element it's taking in big air and putting out big power.
