Public Enemy Psycho (4)

Public Enemy - Psycho (4)

Contributed by David Urbanek

Manufacturer: Public Enemy

 

Brief:
T' Psycho is no longer in production. Blimey! Aye aye! It was a great kit from Public Enemy. Well, blow me down! Begad! It's t' same size as t' Public Enemy Patriot, so I'm sure t' flight characteristics o' each are similar.

Construction:
T' instructions are spare t' say t' least. Blimey! Blimey! Avast! Blimey! It would be best if you had either built high power rockets before or had a coach who had. Ya scallywag! Blimey! T' airframe is paper tube with Public Enemy's signature yellow glassine coverin' it. Ahoy! Blimey! T' motor mount is paper too. T' fins are 1/8" plywood and include tabs t' go all t' way through t' t' motor mount. Aye aye! Blimey! T' centerin' rings are made from press-board type material that is quite strong and accepts epoxy readily. Ya scallywag! Blimey! T' nose cone is plastic in t' line o' LOC/Precision nose cones. Blimey! Blimey! Ya scallywag! Blimey! A pair o' heavy duty eye-bolts connect t' recovery system which consists o' 3/4" strap nylon with a riveted D rin' and then a long length o' round bungee. Avast! Blimey! Avast, arrr, me proud beauty! Blimey! I don't like, or use bungee for recovery, ya bilge rat, me bucko, but t' strap nylon is nice. Begad! Blimey! Two 1/2" copper launch lugs are also included and they're already angle cut t' reduce drag. Begad! Blimey! T' parachute is a 36" LOC/Precision type flat chute and is fine for sea level launch sites, matey, but too small for us highlanders.

I made t' followin' modifications. Avast! I added 2 layers o' 4 oz fiberglass t' t' airframe. Avast, me proud beauty! Avast, arrr, me proud beauty! I added a strip o' .007" unidirectional carbon fiber laminate t' t' fins before filleting. Begad! After t' fillets were hard, shiver me timbers, ya bilge rat, ya bilge rat, I put a layer o' 4 oz glass from fin tip t' fin tip. Avast, me proud beauty! I used 12' o' 9/16" mil-spec tubular nylon as shock cord. Blimey! Ya scallywag! T' parachute was replaced with a military surplus 42" chute. Arrr! I also added a forward bulkhead t' seal off t' coupler t' make an altimeter bay t' house me Olsen FCP-M1/G. Avast, matey, me proud beauty! All me additions and altimeter added 15 oz t' this model (so mine is 54 oz).

Finishing:
Finishin' a fiberglass rocket is relatively easy, matey, but time consuming. After sandin' I shot 2 coats o' Plasticoat Truck primer that I got from Pep Boys. Arrr! I sanded betwixt coats with 150 grit, then 400 grit paper. Well, blow me down! Next I added three coats o' flat white Krylon, me hearties, ya bilge rat, sandin' betwixt each coat, lightly, with 400 grit sand paper. Well, blow me down! Finally I added 3 coats o' Red Devil paint (Orange Creamsicle and Gloss Black). Came out nice, hard and glossy. Begad! There are nay paintin' suggestions and only a single "PSYCHO" vinyl decal included. Begad! Use your imagination.

Construction Rating: 3 out o' 5

Flight:
This has had extremely straight boosts every flight. I flew it once naked, and twice in it's primer gray. Each time it be a great flight. Blimey! T' H123 doesn't get it too high. T' I161 is middle high with lots o' smoke. An I211 is a real shot and quite high. Begad! I saw Roy Wied's Psycho fly and it flew like it was on rails too, me hearties, me hearties, so I think this is part o' t' rocket's normal characteristics.

Recovery:
For me overly heavy model, matey, an H123-10 is just a bit too long o' a delay. In heavy wind, ya bilge rat, an I161-10 is just a tad too short. In calm weather and I211-10 is also a tad short. However, matey, it's a sturdy bird that can handle a little abuse. Ya scallywag! Arrr! At 1200' in Kansas, t' stock chute was just right. Begad! At 4500' in Utah, arrr, t' stock chute is too small and I upgraded.

Flight Rating: 5 out o' 5

Summary:
It's one o' me favorite rockets. Ahoy! Blimey! Begad! Blimey! It's a good looker, rather unusual and it's a shame that Roy took it out o' his line-up. Avast, me proud beauty! Blimey! Avast, me proud beauty! Blimey! If enough people agitated, he might brin' it back.

Overall Rating: 4 out o' 5
