    Recently picked up a A/T Mirage a friend wasnt gonna fly - went through everything and ran a few sims, but just wanted to hear from some that may have flown one , whats the largest 29mm you flew and how did it work out ??
    At this point I will more than likely go with a CTI \H90 because I have the case and a vendor.
    - but Im more than open to suggestions. gonna pop at the top on the factory chute with a JLCR .

    I fly my stock Mirage on AeroTech G40 motors. :)

    looks like it weather cocks a bit , how long was the rod ? Any idea of altitude on the G40 ??
    I really would like to hit it a little harder off the pad - unless someone thinks thats a poor idea for a long rocket .

    I believe it was a six foot long 1/4" diameter launch rod.
    A moment after the launch picture was taken, the Mirage was flying straight.

    This is very similar in size to the Astrobee-D, which I used to fly on 3G H128 & H165 motors. If you use AT RMS-Plus motors, use masking tape in place of the plastic charge well cap. :eek: I used rail buttons and a 6' rail.

    Thrust Curve is a great source for motors that will work and not work for a given rocket. Shows fps off rod or rail, velocity in flight, delay times, acceleration, and altitude for each motor.
    Just need airframe diameter, mm diameter, mm length and weight.

    I have simmed it a bunch of times in OpenRocket , its just always nice to hear some REAL WORLD results as well .
    I do believe either a single use G80 or a CTI H90 will be my choice- as long as the wind plays nice. Never flow one this long , but I cant imagine a breezy day being a good choice ?? lets hear it ???
