I'm a little confused.
My Aerotech Airspike (Mustang w/o decals?) has a 29mm motor mount. I picked up the web special and received the rocket with two F20s. The F20's appear to fit correctly with the single 1" spacer that comes with the Airspike. The specs on the Econojets say these are 73 mm long but there are no dimensions of 73mm anywhere on the motor. The casing is 83mm.
My questions become these:
1) Should an F20 use either of the cardboard spacers in addition to the 1" spacer that comes with the kit?2) Will a 29/40-120 RMS fit into a mount like this?
3) Are the F25 and F50 longer? Specs say they are 98mm long.4) Any idea where the 73mm dimension came from?
Please let me know.
Thanks.
