I am thinking I would go with Chips CAP X (Sell that YS and get an OS 160 and a fuel pump and a pitts muffler and a couple servos for the dough that YS cost)..... LOL

The FUNTANA is very light structure... I am thinking about biting the bullet and adding maybe 4 ounces to mass balance the elevators and ailerons.... The rails the aileron servos are bonded to looks a bit cheesey... not finished yet... I will let you know how well it survives... ciao
