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

Construction:
High quality balsa nose cone, plywood ring, and eye bolt were supplied by Sandman. Estes BT-80, arrr, 24mm heavy duty motor tube, two lite-ply centerin' rings, shiver me timbers, fins are 3/16" balsawood, Keelhaul®©™® shock card, and motor retainer hardware. Avast, me proud beauty! Blimey! 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, me hearties, I installed two #4-40 blind nuts for t' motor retention bracket. Blimey! Blimey! Avast! Blimey! 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. I drilled a 3/16" hole in t' top centerin' for me 1/8" Keelhaul®©™® shock cord t' go through. Aye aye! 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". Blimey! I hardened each end o' t' BT with thin CA for strength. T' next step was t' I fill t' spirals. Avast, me proud beauty! After sandin' t' BT, arrr, t' tube be marked for t' fin locations and t' launch lugs. T' bottom launch lug is flush with the bottom o' t' BT. T' upper lug is 4-3/8" from t' top o' t' BT. Aye aye! Each launch lug was 3/16" diameter and 9/16" long. Ahoy! Well, blow me down! T' motor mount was glued into t' BT usin' wood glue that created a nice fillet around t' top centerin' ring. Begad! Begad! A wood glue fillet be also created around t' bottom centerin' ring. Aye aye! T' fins were cut from hard 3/16" balsa and shaped. Blimey! T' fin and launch lugs were glued on with epoxy. Avast, me proud beauty! Ya scallywag! Once dry, shiver me timbers, 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. Avast, me proud beauty! Once dry they were sanded smooth and coated usin' thinned spackle that was brushed on t' fill t' wood grain. Well, 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! Ahoy! T' nose cone was painted black usin' two coats o' old formula Krylon spray. Blimey! T' body was painted metallic red usin' two coats o' Rustoleum spray. Ahoy! Once dry t' body was smoothed usin' super fine steel wool. Once shipshape and dust free t' body was shot with two coats of Rustoleum clear. Begad! It was really cold durin' t' paintin' process for this rocket, arrr, matey, but t' results were still acceptable. To finish t' model, matey, ya bilge rat, t' decals were installed. Overall it looks fantastic.

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

Recovery:
Since t' fins on this upscale start t' get large, I would use t' through t' wall method next go around. Ya scallywag! Aye aye! Although I feel very good with me method t' attach fins and strengthen them with fillets, TTW is king.

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