The CG is just about 13" from the rear without the motor, within 1/2" either way is fine. I would guess the CP is about 5" to 7" from the rear.Originally posted by brianc
Did you see my earlier plea for a CP location?

I would calculate the region that occupies a median position of atmospheric dynamic pressures in relation to the geometry of the airframe if in motion through a gas medium w/ ±14psi at V>0 to be greater than (±5.00") but not less than (±7.00") from the trailing edge of the airframe structure assuming airframe orientation is parallel to theoretical horizontal plane with the positive Y axis ascending from the center of a given gravity well.Originally posted by brianc
Guess?!? GUESS?!?!?
Is this rocket science or, OH nevermind, your tagline says it all-

Here's a SHX-15B building tip....
A BT50 tube under the wing tip makes it easier to keep the wings level as the glue dries.

Oh, I am scared! I see SHX-15B optional builds!Originally posted by brianc
Not madness, but a pair of 24mm MMTs might be interesting...
I have a single-to-dual MMT quick-change design bouncing around
my head. I might just try it here. <img src="https://rocketryforum.com/images/icons/icon6.gif">

Okay...I'm thinking about straying from the norm here and putting a 3 cluster in this. I don't have the sim file on this...Shrox can you tell me adjustments I might have to make...if any?
I am angry and hurt. Please continue, it looks great.Originally posted by OKTurbo
Hey Shrox,
I hope you don't mind me posting these build pics on this thread. I've kinda started to take over.....sorry.
I can start a new thread if you'd like.

BTW- I decided not to go with the cluster this time around, so
mine's built 'stock'.
