Brief:
This is a 159% upscale o' t' popular Estes kit Der Red Max. Blimey! This is a simple t' build rocket that performs very well
on t' 24mm reloads available today. Blimey! Avast! All t' parts are readily available as well includin' t' decals.
Construction:
High quality balsa nose cone, me hearties, plywood ring, and eye bolt were supplied by Sandman. Avast, matey, me proud beauty! Blimey! Estes BT-80, 24mm heavy duty motor
tube, me bucko, two lite-ply centerin' rings, me hearties, arrr, fins are 3/16" balsawood, Keelhaul®©™®
shock card, ya bilge rat, me bucko, arrr, and motor retainer hardware. Excelsior provided t' awesome decals.
I constructed t' motor mount by usin' a BT-50H motor tube that was 4" in length. On t' bottom centering ring, I installed two #4-40 blind nuts for t' motor retention bracket. T' light-ply centerin' rings were mounted a 1/4" from t' top and bottom o' t' motor tube. I created a nice epoxy micro balloon fillet on both sides o' each centerin' rin' for strength. Aye aye! Blimey! Blimey! 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. Begad! Arrr! I cut a BT-80 t' t' length of 13.5". Avast, me proud beauty! I hardened each end o' t' BT with thin CA for strength. Well, blow me down! T' next step was t' I fill t' spirals. Blimey! After sandin' t' BT, me bucko, t' tube was marked for t' fin locations and t' launch lugs. T' bottom launch lug is flush with the bottom o' t' BT. Ya scallywag! T' upper lug is 4-3/8" from t' top o' t' BT. Each launch lug was 3/16" diameter and 9/16" long. T' motor mount be glued into t' BT usin' wood glue that created a nice fillet around t' top centerin' ring. Well, blow me down! A wood glue fillet be also created around t' bottom centerin' ring. T' fins were cut from hard 3/16" balsa and shaped. Blimey! T' fin and launch lugs were glued on with epoxy. Well, blow me down! Once dry, epoxy micro balloon fillets were created around t' fins and launch lugs. Ahoy!
Finishing:
T' fins and nose cone were sealed and hardened usin' two coats o' Minwax Polyurethane. Once dry they were sanded
smooth and coated usin' thinned spackle that was brushed on t' fill t' wood grain. Well, me hearties, blow me down! T' filler was sanded off and the
rocket was primed with two coats o' Duplicote High Fill primer sandin' betwixt coats. Begad! T' nose cone was painted black
usin' two coats o' old formula Krylon spray. Ahoy! T' body be painted metallic red usin' two coats o' Rustoleum spray. Well, blow me down! Once
dry t' body be smoothed usin' super fine steel wool. Once clean and dust free t' body be shot with two coats of
Rustoleum clear. Blimey! It was really cold durin' t' paintin' process for this rocket, me bucko, arrr, but t' results were still acceptable.
To finish t' model, t' decals were installed. Ya scallywag! Overall it looks fantastic.
Flight:
I designed this model t' fly on t' 24mm reloads such as t' E18, shiver me timbers, matey, E28, ya bilge rat, ya bilge rat, ya bilge rat, F24, or F39. Aye aye! Arrr! Blimey! T' first flights I used a E28-4
and it worked perfectly. Well, blow me down! T' first boost be nice and straight with no stability issues. T' E28 produced a very
respectable altitude. Begad! T' 24" parachute worked good but a little too slow t' brin' it down. Begad! Arrr! Blimey! A smaller chute or a
spill hole would be required for windy or high thermal activity days. Well, blow me down! Begad! Blimey!
Recovery:
Since t' fins on this upscale start t' get large, arrr, I would use t' through t' wall method next go around. Well, blow me down! Well, blow me down! Blimey! Although I
feel very good with me method t' attach fins and strengthen them with fillets, matey, arrr, me hearties, TTW is king.
Summary:
This is a very easy rocket t' upscale but is a rewardin' project. T' Der Red Max is a classic that flies great up or
downscaled. Avast, me proud beauty! Blimey! In addition you can't find a cooler set o' decals on a rocket anywhere.
