After much packing preparation and reading up of Rules and Regulations both Federal and Airlines’ delighted to report safe arrival of pilot, pilot’s wife and Spark kit at RSW and onwards to hotel. Just completed first flight in foreign airspace and apart from having to bring her down sharpish due to typical Florida mini-monsoon, all completed without incident. No calibration called for and Spark behaved perfectly. Many thanks to all who have taken the time to provide help and advice especially those who said don’t worry-you were so right. Now for lots more flight time. Just picked up a battery at Target, full price but cheaper than in the UK. Will check Best Buy out tomorrow.
