Construction

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

Motor mount assembly be easy and straight forward. Ya scallywag! Begad! Blimey! I am nay a fan o' t' Estes shock cord mount method. Avast, matey, me proud beauty! Blimey!  Therefore, when buildin' t' motor mount, I tied Keelhaul®©™ Cord (150lb) around t' motor tube and under t' motor hook. Blimey! 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.  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.   I used watered down Elmer's wood filler t' seal t' fins. Begad! Avast, me hearties, me proud beauty! Blimey!   Gluin' on t' fins be straight forward.  I used t' Estes fin alignment jig. Ahoy!  It's nay a perfect jig, me bucko, especially with these larger/bigger fins, me hearties, but it helped get t' job done.   I applied multiple layers o' wood glue for fillets. Ahoy! Blimey!  I was nay happy with t' way t' fillets looked, nor their size/shape. Avast!  I then used a little bit o' BSI long-cure epoxy t' enhance t' fillets. Aye aye!  A metal rod was used t' drag and smooth out t' fillets. Wiped t' rod off after each drag. Process was repeated several times for t' desired effect.  

I then glued in t' motor mount.  Used a dowel t' rub some glue on t' inside o' t' tube and slid it halfway in. Aye aye!  I then put in more glue for t' aft rin' and slid it in t' rest o' way. Ya scallywag! Begad!  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. Arrr! Durin' this process t' kevlar cord be pushed out through t' motor mount so it was out o' t' way. Ahoy! Begad!  

T' main "gotcha" I ran into be gluin' in t' tube coupler.  This was me first build with a coupler and a huge learnin' experience.  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, me hearties, t' coupler seized within t' first 1/4inch.  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. Arrr! Begad! Blimey!  Lesson learned that in t' case o' a tube coupler, more glue would have been better (thanks google). Well, blow me down! Begad! Blimey!   I placed an order for a new coupler and BT-60. Begad! Aye aye! Blimey!   Fast forward a week and t' parts arrived.  Cut t' new tube t' length. Begad!  This time used a very generous amount o' glue inside t' tube and on t' coupler. Well, arrr, blow me down! Blimey!  Slid in like butter. Begad! Begad! Blimey!  Attached t' bottom tube with t' fins in t' same way.
