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