Balancing and Set-up
I prefer to balance models using lead shot and epoxy rather than making a moulded
lead piece for the nose.
Tape a small plastic bag to the nose of the model leaving it open at the top.
Put the model on a balancer and pour lead shot into the bag until the model
balances. For now, balance it at 85mm from the leading edge.
Remove the bag from the nose and put to one side. Remove the battery from the
nose of the model. Now mix up enough 30min epoxy to pot the lead shot into the
nose and remove some of the lead shot to allow for the weight of the epoxy. Mix up
the shot and epoxy and pour the mixture into the nose of the model. I like to place a
bit of greased cellophane around the battery and replace it into the nose of the model
so make sure that the nose weight doesn’t get in the way of the battery. You should
find that there is just enough room.
Once dry, remove the battery and the cellophane.
Now rebalance the model and add removable nose weights either side of the
battery to give you a CG of 77mm. This will be your CG for the maiden flight.
Most pilots end up flying the MiniVec around 80mm.
