TAG IN.....

Hi Dave,

I started to do that in my contest in Kansas City last year.  This year in
pilot meeting I said. " If you don't do it the first round will be zeroed.
Well I think worked well"

John F.

You just made my day. I do more or less the same you do. I review a lot of
projects. Clearly will all here analyzed the system and we know the steps
could be used to mitigate a possible situation. That is the end of
discussion in cases like this. Just give me a real possibility of tag in
and tag out.

Jon,

Good research. Now you have to find what is the code that applies to model
airplanes. I knew that there is no one specific code. However existing
codes applies for similar systems. If all if them arrives to the same
conclusion we will be in better shape if we just follow the intent of all
codes you can find. Now try to find the specifics for a system similar to
the one we have. I already know the answer so I don't need to ask our
friend Google.

TAG OUT
