Hello Dave,
Are there any updates from your side? I'm in exactly the same situation as you are. I paid a lot of money back in 2019 to Pirotti to pre order the F35. Until now I didn't received anything. The communication is very difficult and when he react it's another excuse to delay the delivery even more. The last promise was that it will be ready before the holidays started. The holidays in Europe started already two weeks ago. Maybe we can help each other to find a good solutions for this. I will go to Jetpower in Germany in September and he will be there as well.
Best regards,
Egbert
