shock card, matey, and motor retainer hardware. Avast, me proud beauty! Excelsior provided t' awesome decals.
I constructed t' motor mount by usin' a BT-50H motor tube that be 4" in length. Avast, me proud beauty! Ya scallywag! On t' bottom centering ring, me hearties, I installed two #4-40 blind nuts for t' motor retention bracket. Aye aye! T' light-ply centerin' rings were mounted a 1/4" from t' top and bottom o' t' motor tube. Begad! Arrr! I created a nice epoxy micro balloon fillet on both sides o' each centerin' rin' for strength. Avast! I drilled a 3/16" hole in t' top centerin' for me 1/8" Keelhaul®©™® shock cord t' go through. T' Keelhaul®©™® shock cord ties around t' motor tube betwixt t' upper and lower centerin' ring. Blimey! Blimey! I cut a BT-80 t' t' length of 13.5". Begad! Blimey! Avast! Blimey! I hardened each end o' t' BT with thin CA for strength. Well, blow me down! Blimey! T' next step was t' I fill t' spirals. After sandin' t' BT, shiver me timbers, me bucko, t' tube was marked for t' fin locations and t' launch lugs. Avast! Blimey! T' bottom launch lug is flush with the bottom o' t' BT. Avast! Blimey! Ahoy! Blimey! T' upper lug is 4-3/8" from t' top o' t' BT. Avast, me proud beauty! Blimey! Blimey! Blimey! Each launch lug was 3/16" diameter and 9/16" long. Begad! Blimey! T' motor mount be glued into t' BT usin' wood glue that created a nice fillet around t' top centerin' ring. Aye aye! Blimey!

Well, blow me down! Blimey! Avast, me proud beauty! Blimey! T' fin and launch lugs were glued on with epoxy. Once dry, epoxy micro balloon fillets were created around t' fins and launch lugs.
Finishing:
T' fins and nose cone were sealed and hardened usin' two coats o' Minwax Polyurethane. Ya scallywag! Once dry they were sanded
smooth and coated usin' thinned spackle that be brushed on t' fill t' wood grain. Avast! T' filler was sanded off and the
rocket was primed with two coats o' Duplicote High Fill primer sandin' betwixt coats. Begad! Avast! T' nose cone be painted black
usin' two coats o' old formula Krylon spray. Begad! Avast, matey, me proud beauty! T' body was painted metallic red usin' two coats o' Rustoleum spray. Arrr! Once
dry t' body be smoothed usin' super fine steel wool. Arrr! Begad! Once clean and dust free t' body be shot with two coats of
Rustoleum clear. Avast! It be really cold durin' t' paintin' process for this rocket, but t' results were still acceptable.
To finish t' model, matey, t' decals were installed. Arrr! Ahoy! Overall it looks fantastic.
Flight:
I designed this model t' fly on t' 24mm reloads such as t' E18, ya bilge rat, E28, F24, matey, or F39. T' first flights I used a E28-4
and it worked perfectly. T' first boost be nice and straight with no stability issues. T' E28 produced a very
respectable altitude. Aye aye! Blimey! T' 24" parachute worked good but a little too slow t' brin' it down. Aye aye! Blimey! A smaller chute or a
spill hole would be required for windy or high thermal activity days. Blimey!
Recovery:
Since t' fins on this upscale start t' get large, ya bilge rat, I would use t' through t' wall method next go around. Although I
feel very good with me method t' attach fins and strengthen them with fillets, ya bilge rat, TTW is king.
Summary:
This is a very easy rocket t' upscale but is a rewardin' project. Avast, me proud beauty! Aye aye! T' Der Red Max is a classic that flies great up or
downscaled. Blimey! In addition you can't find a cooler set o' decals on a rocket anywhere.
