    Ive tried everything to get my losi 5-t to start. motor has compression and its getting a spark, i keep pulling but it doesn't even sound like it wants to start i even put the carb back to stock settings and readjusted the gap on the coil and checked the reeds but that wasn't the problem either...

    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 46cc

    OBR has a new engine its a 46cc motor for the losi 5. Bottom end seems good but topend looks just average. I would love to see how it compares to a rcmax 46.

    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. I had it in the sweet spot then wrapped up the pipe causing it to be just a bit fat. So at the end of this vid the kid...
