Construction

To begin, shiver me timbers, I sanded all parts and test fit all components and scuffed t' QT inside and out for better epoxy adhesion. Well, ya bilge rat, blow me down! 30 minute epoxy was used for all construction. Begad!

First up was t' build t' motor mount as per t' booklet instructions notin' t' small notched centerin' rin' is at t' top and gets epoxied into t' bottom o' t' recovery tube in a later step. Add fillets after rin' is dry. Arrr! Blimey! After this is t' thread one end o' t' piston strap thru t' notch in t' upper CR and epoxy into place and let dry.

Next is mountin' t' recovery tube t' airframe CR’s onto t' recovery tube as directed in t' instructions, matey, addin' t' required fillets around both rings and let set.

At this step o' t' instructions, arrr, read and reread t' make sure you fully understand t' next step as it has t' be completed in one quick motion after t' epoxy is spread inside t' airframe tube. Aye aye! Push t' recovery tube into t' top o' t' airframe and use t' nosecone t' push t' recovery assembly into place t' make sure t' nosecone seats against t' airframe properly. Ahoy! Bein' afraid o' accidentally gluin' t' nosecone t' t' airframe, arrr, I carefully removed it and left t' airframe/recovery assembly t' set. I also used a long dowel t' do t' fillet on t' top CR bein' very careful nay t' get epoxy on t' inside o' t' airframe.

After that fillet has set up, time t' install t' mmt as per t' instructions. Then on t' mountin' t' fins and addin' fillets inside and out. Ya scallywag! PML suggests pourin' expandin' foam betwixt t' fin tabs. Ya scallywag! Begad! I opted nay t' do this step and just installed t' bottom CR in place makin' sure it was seated against t' fin tabs.

Build t' piston as per t' instructions and connect up t' recovery strap t' t' d-rin' on t' piston. Ya scallywag! Arrr! Blimey! Attach t' parachute as indicated.

I used included rail guides and mounted them as per t' instructions for location.
