Is this just a matter of everything needing to break in and ill just have to keep an eye on it and tighten it up as I go?
Also the outdrives, they do move freely with resistance, but it almost feels like "sandy" resistance, again is that just a matter of things needing to break in? ie. the washers on the outdrives pressed against the ball bearings?
thanks! Ive never built one from scratch before, so I dont want ot make any wrong assumptions
The 2 FT sc10's I built had no issues, my FT B4.1 was like yours, I simply ran it with the one tranny screw (only one caused the issue for me) on the loose side so the tranny wouldn't bind. Ran it one race day and then pulled it apart to see if I could fix the problem, I'm not one to leave something that's just not right. Before I pulled it all apart I tightend up the all the tranny screws and it was fine. I would guess things needed to seat a little inside. It shouldn't be that way but it's all good know.
