I fly weekly to Mexico with my full setup, and have converged on the following:
[*] With about $3,000 in the case, I have decided to carry on, and check my roller back with clothes, etc.
[*] Couldn't get comfort from Alaska that in a loss of checked bag, or pilfering of contents by airline personnel, that my coverage was anywhere near the $3,000 value
[*] Got tired of no wheels, so I bought a Design Go plastic luggage cart ($27 USD). Maiden voyage next week.
[*] GoProfessional case fits easily overhead on every commercial aircraft to date, principally Alaska's 737s.
[*] Used to get "special attention" from TSA, but that seems to be waning. Fewer inquiries of late.
[*] Mexico's SAT (import police) pulled me in to their office once for import charges. I paid $20 for import duties on professional equipment, got a receipt, keep receipt in travel case, and have flashed it since first payment, avoiding subsequent charges. SAT personnel smiled that I knew the system (thanks to my Cabo attorney).
[*] No experience with other countries security or import personnel, but I wouldn't hesitate to carry-on most anywhere in the world.
[*] Wasn't aware that LiPo's are an airline no-no. Is that true?
[*] Statement of the Obvious: I always recalibrate compass on the other end.
