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