Construction

Estes instructions are straight forward IMHO.  T' diagrams are clear and easy t' follow.  I had built other Estes Kits over t' past few months, shiver me timbers, includin' t' Hi-Flier. Well, blow me down! So I wanted t' add this bigger brother XL version t' me collection. Ahoy! Aye aye!  (Born again rocketeer. Avast, me proud beauty! Arrr!  Just started back up Oct 2020 after a 40 year hiatus)  

Motor mount assembly be easy and straight forward. Begad! I am nay a fan o' t' Estes shock cord mount method. Well, blow me down! Begad!  Therefore, ya bilge rat, shiver me timbers, when buildin' t' motor mount, I tied Keelhaul®©™ Cord (150lb) around t' motor tube and under t' motor hook. Well, blow me down! Slipped it through t' notch in t' centerin' rin' and glued t' knot and cord t' t' mount.   Post build I will attach t' kevlar cord t' t' elastic shock cord. Avast, me proud beauty! Begad!  I learned this method when I built a Quest rocket.

It be nice t' be able t' sand and shape bigger fins as compared t' smaller fins/models I had previously built. Aye aye! Avast!   I used watered down Elmer's wood filler t' seal t' fins. Blimey!   Gluin' on t' fins be straight forward. Aye aye! Ahoy!  I used t' Estes fin alignment jig.  It's nay a perfect jig, me bucko, especially with these larger/bigger fins, arrr, matey, but it helped get t' job done. Ahoy! Avast!   I applied multiple layers o' wood glue for fillets.  I was nay happy with t' way t' fillets looked, arrr, shiver me timbers, nor their size/shape. Well, arrr, blow me down!  I then used a little bit o' BSI long-cure epoxy t' enhance t' fillets. Avast!  A metal rod be used t' drag and smooth out t' fillets. Wiped t' rod off after each drag. Process be repeated several times for t' desired effect. Avast, arrr, me proud beauty!  

I then glued in t' motor mount. Avast! Avast, me proud beauty!  Used a dowel t' rub some glue on t' inside o' t' tube and slid it halfway in. Ya scallywag! Begad!  I then put in more glue for t' aft rin' and slid it in t' rest o' way.  Applied fillets t' t' aft rin' and used a dowel t' reach inside t' tube t' apply a glue fillet on t' top center ring. Begad! Durin' this process t' kevlar cord was pushed out through t' motor mount so it was out o' t' way. Well, blow me down! Avast, me proud beauty!  

T' main "gotcha" I ran into was gluin' in t' tube coupler.  This was me first build with a coupler and a huge learnin' experience. Blimey! Avast, me bucko, me proud beauty!  I rubbed a little Elmers wood glue on t' end o' t' coupler as well as inside t' tube.  Unfortunately by t' time I did that and slid it in, t' coupler seized within t' first 1/4inch. Blimey! Avast!  I tired t' push a little harder and in t' process started t' see a small crease/wrinkle in t' tube at one o' t' spirals. Ya scallywag! Avast!  Lesson learned that in t' case o' a tube coupler, more glue would have been better (thanks google). Arrr! Aye aye!   I placed an order for a new coupler and BT-60. Ya scallywag!   Fast forward a week and t' parts arrived.  Cut t' new tube t' length.  This time used a very generous amount o' glue inside t' tube and on t' coupler. Ya scallywag!  Slid in like butter. Well, blow me down!  Attached t' bottom tube with t' fins in t' same way.
