Fixed/variable costs of piston helos
Do all psiton helo's require expensive time/life rebuilds as does, for instance, the Robinson range? I am thinking specifiaclly of either an Enstrom or a hughes 300.
I am a fixed wing owner and know roughly how to calculate the fixed and variable ownership costs assoiciated with 'planks', but I am a little in the dark when it comes to maintenance / rebuilds associated with piston helo's.
Advice gratefully recieved
