    Not much of a build thread but this is pretty cool! Right out of the box, seems pretty sturdy so far, the plastic body is thicker than I expected. Can't wait to see how it flies!

    Looks great! Can't wait to get my hands on one. Really excited to hear how it flew.

    Of course! I don’t think it will even notice. I’m thinking about making an orange and white ‘chute for it too.

    It’s an 18mm mount. Estes says C6-3, I have some Quest C12s on order to try as well.

    I have two on order from AC Supply (as I think I’ve mentioned before). Q-Jet C12-4 is where I’m planning to go with it. Then D16-4.

    Do you all think it's under powered with the 18mm motor? I'd think that most people would be just using the Estes motors. Do you think you could you do some 'configurin' to get a 24mm in there?

    I have some Aerotech D10-5 motors I’m going to try when mine comes in tomorrow.

    Launched one of mine yesterday with first the recommended c6-3 Estes motor then the Q-jet c12-4 planned to follow up with the Q-jet d16-4.
    Clear day ambient temperature 81 degrees, humidity 61% light winds.

    1. Estes C6-4 Alt 175’ (per onboard altimeter) slight roll off pad. Ejection appeared to come after apogee recovered 25’ from launch site.
    2 Q-jet c-12-4 Alt 585 slim roll off pad tracked to south. Ejection before apogee recovered down wind 200 yards from pad.
    Did not attempt d-16 as winds picked up and didn’t feel like losing rocket on first day .

    Hmmmmmm....so maybe if I get to the D16 with mine (they’re supposed to be here tomorrow) I’ll want the -6.

    What altimeter did you use, just out of curiosity?

    Sadly, our club launch was rained out last weekend so I still haven't gotten to fly yet.

    I'm picking up a couple more cases on Monday and might pull another one to try a 24mm conversion. It looks like it would be easy but you never know for sure until you get it open!

    I got my two from AC Supply today.

    I can't see reworking the motor mount (there is no tube, per se, just the aft sleeve for the screw-on retainer which also holds on the flight fin unit on and a boss or ring that the forward end of the motor fits into), motor retention and clear fin unit to get a C11 or D12 in it. MUCH simpler to just get some Q-Jet Cs or Ds.

    I checked - Q-Jet Cs/Ds fit with no issues. The Aerotech D10/D21 fit snugly....but based on prior experience flying these in a model with a plastic motor mount you might only get one flight before the motor mount is damaged as their cases are really hot post-flight. An 18/20 RMS case fits also, but the screw-on retainer can't quite snug down enough to hold the fin unit tightly. Not sure about trying that either.

    I'll be flying mine primarily on Q-Jets as I expected, though I may try the recommended Estes C6-3 once.

    Mine came today. I think it’s a pretty cool model and probably the nicest RTF rocket I’ve ever seen. The shock cord is the wimpy Estes rubber band, and it comes with a standard Estes purple and white plastic chute. I’d like to upgrade both of those.

    I’m surprised the C12-4 went so much higher than the C6-3 — more than 3 times as high. I’m not really sure I want this model going all that high, but the C6-3 seems too low. I have some D10-5 motors, and I’m wondering now if that’s a bit more impulse than I really want.

    I agree that converting this for 24mm would be a lot of work and probably not worth it.

    Do you really think the D10 would damage the plastic motor mount? I bought some D10-5 motors specifically to use with this model, but I’ve never flown one before, and I don’t want to damage the rocket. Do they really get hot enough to cause damage?
