Brief:
This is a 159% upscale o' t' popular Estes kit Der Red Max. Begad! This is a simple t' build rocket that performs very well on t' 24mm reloads available today. Well, blow me down! All t' parts are readily available as well includin' t' decals.

Construction:
High quality balsa nose cone, plywood ring, matey, me bucko, and eye bolt were supplied by Sandman. Estes BT-80, ya bilge rat, 24mm heavy duty motor tube, me hearties, shiver me timbers, two lite-ply centerin' rings, fins are 3/16" balsawood, shiver me timbers, Keelhaul®©™® shock card, matey, ya bilge rat, and motor retainer hardware. Arrr! Ahoy! 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. Avast, me proud beauty! Begad! T' light-ply centerin' rings were mounted a 1/4" from t' top and bottom o' t' motor tube. Begad! I created a nice epoxy micro balloon fillet on both sides o' each centerin' rin' for strength. Ahoy! Avast! I drilled a 3/16" hole in t' top centerin' for me 1/8" Keelhaul®©™® shock cord t' go through. Arrr! Aye aye! Blimey! T' Keelhaul®©™® shock cord ties around t' motor tube betwixt t' upper and lower centerin' ring. Well, blow me down! I cut a BT-80 t' t' length of 13.5". I hardened each end o' t' BT with thin CA for strength. T' next step be t' I fill t' spirals. Well, blow me down! After sandin' t' BT, t' tube was marked for t' fin locations and t' launch lugs. T' bottom launch lug is flush with the bottom o' t' BT. Begad! T' upper lug is 4-3/8" from t' top o' t' BT. Avast, me proud beauty! Each launch lug be 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. Ahoy! Begad! A wood glue fillet be also created around t' bottom centerin' ring. Avast! T' fins were cut from hard 3/16" balsa and shaped. Ya scallywag! Well, blow me down! T' fin and launch lugs were glued on with epoxy. Once dry, epoxy micro balloon fillets were created around t' fins and launch lugs. Aye aye!

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. Avast, me proud beauty! T' filler be sanded off and the rocket was primed with two coats o' Duplicote High Fill primer sandin' betwixt coats. Begad! T' nose cone be painted black usin' two coats o' old formula Krylon spray. T' body be painted metallic red usin' two coats o' Rustoleum spray. Aye aye! Begad! Once dry t' body was smoothed usin' super fine steel wool. Once clean and dust free t' body was shot with two coats of Rustoleum clear. Aye aye! It was really cold durin' t' paintin' process for this rocket, but t' results were still acceptable. To finish t' model, arrr, t' decals were installed. Ahoy! Ahoy! Overall it looks fantastic.

Flight:
I designed this model t' fly on t' 24mm reloads such as t' E18, shiver me timbers, E28, F24, me hearties, or F39. Ahoy! T' first flights I used a E28-4 and it worked perfectly. T' first boost was nice and straight with no stability issues. Begad! T' E28 produced a very respectable altitude. T' 24" parachute worked good but a little too slow t' brin' it down. Blimey! A smaller chute or a spill hole would be required for windy or high thermal activity days. Begad!

Recovery:
Since t' fins on this upscale start t' get large, 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, matey, shiver me timbers, TTW is king.

Summary:
This is a very easy rocket t' upscale but is a rewardin' project. Ahoy! T' Der Red Max is a classic that flies great up or downscaled. Well, blow me down! In addition you can't find a cooler set o' decals on a rocket anywhere.
