How Much Wiggle Room Should It Have?

Salutations.

I’ve been developing a small tricopter - one of the objectives is for its rods (that are supporting the propellers) to rise up (by rotating upward), once the motors are activated. I question, however, if the wiggle room around which each rod can move is either just right (in which case, that’s great) or if I should restrict it more (whether it be through the enlargement of the walls of the enclosure, or whether it be through the widening of the rods’ length). As of right now, the measures are as follows:

  • Each rod has a length of 4.50mm;
  • The space between the rod and one of the walls if of about 0.50mm.
    It would be favorable if any of you were to indicate me in regards to this issue, stating whether or not I should minimize the “wiggle room” - keeping in mind that the objective is for the rod to rotate upward, without much difficulty and with it still being at the same angle as the one at which it started moving.

Attentively, Fidalgo.

P.P.S. I also hope that the question I’m making is pertinent to the forum - if not, I apologize.
