John,
The project has been in a long hiatus, the performance of the prototype is encouraging. The last test runs we were getting an average of 21lbs at around 16k rpms, Research and Developing and testing a prototype is expensive and sometimes life tends to throw some curve balls and funds allocated for fun hobby projects have to be diverted.
I need to put the project back into priority and make time and build a Byron F-20 I have boxed in the garage, and test fly it.
Thanks again for the message.
Joe
