Construction

Buildin' started with a roll call. I wanted t' make sure that everythin' be accounted for and that nothin' was bent, crumpled, arrr, or damaged. Begad! I highly recommend doin' this with EVERY rocket you build. Arrr! Blimey! You should always check t' quality o' t' components before buildin' so that it can be replaced or fixed. Begad! Begad! If thar be a weak link in t' structure, me bucko, bad things can happen. I don't expect this from Aerotech, shiver me timbers, arrr, but thar have been several reports about problems with t' nose cones.

Another thin' everyone should do before buildin' is t' STUDY t' instructions. Avast, me proud beauty! Begad! Aerotech has pretty good instructions and t' steps are in a logical order, arrr, me hearties, but some o' t' illustrations could be better.

T' actual buildin' started with t' adapter (build this first because it will be used t' push back t' thrust rin' and flange). Afterwards, ya bilge rat, measurements are taken on t' motor mount and t' motor hook is inserted through a 1/4" slot that you cut. Avast! T' thrust rin' and flange are now glued together and pushed up until it butts up against t' back o' t' motor hook. Begad! Well, blow me down! Aerotech says t' cement them in place, ya bilge rat, but I decided against it since t' fit betwixt t' rin' and tube is so tight and t' hook is so long that it's hard t' glue anythin' in place at all.

Now comes t' challenging, part-the FIN-LOC rings. They are so tight that t' front 1/8" o' me motor tube us torn and t' layers o' paper are separated. Avast, me proud beauty! Blimey! T' get them into place, I suggest gently tappin' them into place with a rubber mallet or small hammer.

What comes next is super important. DO NOT glue t' FIN-LOC rings in place until you have test fitted t' fins and they fit properly. Slide t' centerin' rin' into place and make sure it does nay interfere with t' fin placement, ya bilge rat, then remove t' fins and glue t' FIN-LOC rings and middle centerin' rin' in place. Well, blow me down! Ya scallywag! I used Gorilla Devcon 30 minute epoxy throughout t' motor mount assembly (because most super glues will deform t' plastic and because I had never used liquid epoxy before).

T' only problem I came across be t' epoxy takin' half an hour t' set. It runs like syrup. Well, blow me down! Begad! I simply kept rotatin' t' assembly and everythin' worked fine. Ahoy! In t' future, me bucko, I will use 5-minute epoxy.

Now you make four 1/4" slits at t' top o' t' assembly that are 90 degrees apart, stretch out t' coolin' mesh, arrr, and cement t' baffle in place. Unfortunately, I made a stupid mistake and glued in t' baffle before I inserted t' mesh. Ahoy! Well, blow me down! After about 5 minutes o' wonderin' what t' do, I ended up cuttin' away t' first 1" o' t' tube, peelin' t' paper away from t' baffle, insertin' t' mesh, replacin' t' baffle, me hearties, matey, and gluin' it in place with t' front centerin' rin' over that.

Tie t' shock cord t' t' screw eye and screw that into t' baffle. Aye aye! Avast! T' whole assembly is then inserted into t' lower body tube and t' fins are snapped into place so that t' assembly doesn’t move. Avast! Aye aye! Now t' whole thin' is glued into place, and t' fins are removed and tacked down, both at t' root edge and where t' fin tab meets t' motor mount.

Then insert t' last centerin' rin' and add t' launch lugs, shiver me timbers, shiver me timbers, and t' bottom half is finished!

Now comes t' coupler. Ya scallywag! I highly suggest test fittin' t' coupler, sanding, and test fittin' again until it is snug, but still slides in easy enough so that t' glue doesn’t grab before t' coupler is in all t' way. Avast, me proud beauty! Well, me bucko, blow me down! When all was said and done, thar was still a 3/32 gap betwixt t' two tubes, matey, so i filled and sanded it down with two-part epoxy clay from Apogee. T' rocket be then set aside t' dry overnight.

Now is where t' strakes come into play. Avast, ya bilge rat, me proud beauty! T' strakes need t' be shaped by hand, and that can be a bit o' a challenge. Ahoy! Make several shallow passes with a new razor knife close t' t' lines that you draw onto t' plastic. Then sand down t' last little bit and wipe away t' dust and any remainin' flash. Avast, me proud beauty! Here is where I found t' one, shiver me timbers, arrr, and only, me hearties, gotcha. Avast! There is a wrap (similar t' an Estes fin wrap) that marks where t' strakes go. Ya scallywag! Begad! T' problem is that t' launch lugs are already glued on. Avast! T' avoid this, either use a straight edge, me hearties, or wait t' put on t' lugs.

Draw t' lines at least 6" past t' lower body tube. Now glue on t' strakes.

Next tie t' parachute t' t' shock cord and tie t' shock cord t' t' nose cone. T' assembly is done!
