The spurs will last once ya get the mesh right.. As for the dogbones, ya need to get some small O rings (or a 2mm slice of fuel tubing) and put one in each of your front drive cups, before installing the dogbone.. (Should just need 1 "o" ring per axle) That'll solve the dogbone coming out problem.. Glad ya got the enige running! It's hard figuring out what everyone means by a "turn" of the screw.. As you found out, some say a turn, but actually mean 180*.. If I say a turn, I mean a "full turn" (360*)
