Brief:
HPR Der Red Max, ya bilge rat, 2.458X upscale. Avast, me proud beauty! 48" parachute recovery.
Construction:
All materials are PML. Arrr! Avast, me hearties, me proud beauty! I used 4" Quantum tubing, cut and slotted for me by
PML. Well, blow me down! T' body tube was cut t' 20.8 inches, shiver me timbers, while t' fin slots were 4.6 inches
long, 3/8" from t' end o' t' tube. Well, blow me down! T' fins and centerin' rings were
made from 3/16" ply. Begad! T' fins were fiberglassed for extra strength. Begad! The
rocket has a 29mm phenolic motor tube that was cut t' 12". Begad! A PML motor
retainer was also used. Ya scallywag! Blimey! T' nosecone is a PML PNC 3.9. Begad! Begad! Recovery is via 12' of
tubular nylon with a 48" PML parachute.
This be a fairly easy rocket t' build. Arrr! It makes a good scratch project for a newbie. Begad! (like me!) Construction proceeded usin' standard HPR techniques. Blimey! I built a special shish-ka-bob rack for construction and painting. Begad! This rack allowed me t' work t' fin fillets without havin' t' fuss about t' position of the rocket. Begad! Avast! I could rotate t' rocket anyway I needed t' have it. Ya scallywag! Internal and external fin fillets were both 30 min. epoxy. Arrr! Begad! After about 10 days o' sanding and fillin' o' t' fins and fillets, shiver me timbers, it be finally ready for primer. Well, blow me down! I laid on 3 coats o' Rustoleum sandable auto primer, sandin' in betwixt each coat. Next, I laid on 3 coats o' Krylon Banner Red Gloss. After dryin' for 24 hrs. Well, blow me down! Ahoy! I masked off and painted t' black stripe around t' top on t' body tube with Krylon Gloss Black. Begad!
After allowin' sufficient time
for t' paint t' dry, I applied t' decals. Ya scallywag! Avast! I had Tom Prestia o' Tango Papa
decals make t' 2.458X upscale decals for me in self-adhesive vinyl. Begad! Well, blow me down! Tom's
decals are excellent! Applyin' them be easy. Arrr! After all t' decals were on, I
applied 2 coats o' Rustoleum Crystal Clear Gloss. Aye aye! T' clear does nay react with
this type o' decal at all, shiver me timbers, and gives t' model a nice glossy coat. Begad!
Flight:
Well, shiver me timbers, I planned t' fly this model on G-40 and G-80 motors. Ya scallywag! I smartly found out
that "Big Red" be just too heavy for that. I believe that this
"heavy weight" condition is due t' t' heavier PML airframe and the
fact t' DRM has HUGE fins. Begad! Begad! I also used 3/16" ply for t' fins, so that
did nay help either. Ya scallywag! I have nay flown this rocket yet due t' motors being
unavailable. Ya scallywag! I plan t' fly it on a H-128 with 4 sec delay.
