Oh, of course. I have my butler tear down all servos and inspect all the gears under magnification after every flying session. I also have him check out the battery packs, switch harness and RX under full load on my ultrasonic test bench.
When he's completed those tasks, then he tears down the engines completely for Zyglo and magnaflux inspection of all moving parts. While he's at it, I have him demagnitize the crankshafts to reduce unwanted drag.
We also firmly believe in tossing all control linkages every 4 flights and redoing all hinges, just to be sure.
This way, we are sure to never have any mechanical failures or to need more than 1 plane at a time at the field.
