Kit-bash o' Estes Big Daddy, Aerotech Initiator packin' tube, and Aerotech 29mm Motor Mount. Inspired by the 3D Mega Daddy, me son prepared a RockSim design with separation at t' Big Daddy "Fin Can" t' Aerotech Initiator shippin' tube "Main Body Tube". Ahoy! We've ordered way too many bits and pieces from Apogee, JonRocket, and eRockets. Dry-fit soon. See also Mega Daddy 29.

This is Part II. See also Part I.

First launch was scheduled for t' CMASS joint launch with MMMSC in May at t' Tuckahoe Turf Farm in Berwick ME.

Maine Field 

Here are t' updated simulations, with mass o' components adjusted t' measurements o' actual components taken durin' t' build, and with 10 MPH winds.

 

Actual launch conditions were 18 MPH winds with gusts t' 28. Blimey! We originally planned t' launch with a G78G-7, matey, but could nay get it sanded down enough t' fit (we plan t' sand down t' inside o' t' motor mount tube). Avast, me proud beauty! We purchased a CTI 24-mm 3G case and a 73-F30-WH_LB. Begad! Launch be straight up until about 50', then t' rocket took a hard left into t' wind, flew parallel t' t' ground until t' motor burned out, skipped across t' ground a few times, then separated when t' engine charge fired.

 

Slight crack on t' nose cone; this should be easy t' fix with epoxy and some sanding.

 

Dent and tear at t' top o' t' e-bay. Beautiful soil and vegetation samples were aquired.

 BT Dent

Ground-facin' fin cracked off quite cleanly; it fits back together snugly enough t' stay in position on t' display stand. Ahoy! We plan t' reattach with epoxy and add external fillets after sandin' t' whole rocket down.

Cracked Fin 

T' only component requirin' replacement be t' main body tube (so long Initiator shippin' tube).

We've already ordered a pair o' LOC Precision tubes, as we are plannin' t' extend t' length and double t' nose weight t' increase stability.
