EZI-65 Test Flights

Anyone have suggestions for a good sequence of motors to use in testing an EZI-65?  I have the info from the
blurb sheet included with the kit, but would like to have actual opinions from those of you who have flown
this model.  (No hurry, it's snowing like the***ens at the moment and I don't expect to see good flyig
weather for at least another month or so... Sigh, life in Wonderful Wyoming ;)  ).

   Here are motors I've had success with in my EZI.  It is worth noting that
you can fly it without the payload section and as such mine weighs in just
at the 3.3 lb mark with a G reload (thus no waiver needed, just notification).

Aerotech G80-4, single use
Aerotech G64-4, 120 nt-sec 29mm reload
Aerotech G75-S, 160 nt-sec 29mm reload
Aerotech H128-S, 180 nt-sec 29mm reload
Aerotech H238-S, 180 nt-sec 29mm reload
Aerotech H180-M, 240 nt-sec 29mm reload
Aerotech I161-L, 360 nt-sec 38mm reload
RocketFlight G160-5
RocketFlight H220-7

   I hope this is helpful.

Also try it on a J90-M . You may need a litle extra nose weight. But it
does produce an awesome flight

here's a suggestion of what NOT to do .... everyone with an
EZI and a set of 54mm reload casings eventually thinks of
sticking a J275 in it ..... it will go mach and rip the fins off
(it is possible but you need to fibreglass just about everything).
I have made this mistake and seen at least 2-3 other people
do it too

Well, for a 1st flight, try a G80-4. Some people actually leave off the
payload section when flying it on this motor. Next, assuming you have
some H class reload hardware from Aerotech, try an H180-6. It worked
great in my EZI-65! If you don't have the reload hardware, most
expendable H's with a 5 to 8 second delay work well.  

For an 'I' class flight, start with a low-impulse I such as an I161
[reload] or an I210 [Aerotech expendable], both with 10 second delays. I'd
recommend the Aerotech I95, but I lost my EZI on that very motor when it
headed downrange at a 60 degree angle [to the horizon].  After this one,
go for a full 'I'! Something like an Aerotech I132 or a Vulcan I283 with
a 10 second delay make for great flights.  Or, for the ultimate
experience, get an I65 and watch it keep going and going and going...
