How many servos for GFC500?
Where’s the shop?
A GFc500 3 servo parts and installation runs about $17500. I pulled this from Lafayette avionics website.
The parts alone for G3X and 275 run about $17500.
So now we have $20000 unaccounted for.
So figure $100/hr labor that’s 200 hours of labor to do everything you listed above, except the GFC labor already accounted for. A little high, but not unreasonable if labor rates are higher than my ballpark estimate. If this is California, probably spot on, if in southeast, not so much.
