David,
You have a very valid question...and I know where you question is coming from.
The way Tam runs his business is that when he comes out with a new aircraft, it is test flown out here (by me) and thoroughly tested for no less then 100 flights as we take notes on any changes that we think need to be made before production starts. After testing is complete, Tam travels to China and supervises any changes himself and plans the production of the kit. Once the first container arrives, then all dealers and customers are immediatly shipped out their aircraft, while the other kits are placed into stock to accomodate future orders from customers/dealers. Tam realizes that this kit will be very popular and has increased the production numbers in response.
I hope this answers your question, if not please feel free to re-post or call my cell phone at (831)207-9539.
Thank you for your interest,
Dave
