yeah i feel ya. dont mind the wrenching but its tough with two kids around and one day off a week to spend with them and the wife. love the long races too, one of my favorite things to do is run a long main with the nitro guys! never tried to go longer than 20 mins but didnt hit lvc and temps were reasonable. only bummer is the marshals love to start carrying the car off the track cuase its not making any noise dude no cooling head sticking out guys
