>Is there anyway to accurately determine the delay on a Aerotech
Not unless you live in Las Vegas. <g>
>The feedback I'm always rec'ving is that the delays are way way
I wouldn't say they are "way way" off. I don't know if I'd even go
as far as saying they are way off, except for a few cases here &
there where one might explain the delays being of on reloads due to
the (improper?) motor assembly. For example.. I recently witnessed
a case where the flyer most unknownly swapped a 7sec delay from 1
kit with a 4 sec from another. In this case 3 secs was way off as
the rocket lawn darted. Yes there are a few motors where the delay
may be off by some factor, but I'd say it's usually consistant for
a given motor. In any case where I see most delay inconsistantcies
being a problem is with the blackjack motors. They're a problem not
only because the delays tend to be longer than given, but because
the flyer has underestimated the altitude or the rocket
weathercocks, both of which give the "perception" the delay was
"way way" too long as the rocket crashes before ejection.

Fly, Fly, Fly, and fly some more. The more you fly the more you
get to know how each motor/delay/rocket combo performs which will
help you to better achieve success in the future.
