Public Enemy Psycho (4)

Public Enemy - Psycho (4)

Contributed by David Urbanek

Manufacturer: Public Enemy

 

Brief:
T' Psycho is no longer in production. Blimey! It was a great kit from Public Enemy. Ahoy! 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. It would be best if you had either built high power rockets before or had a coach who had. Ya scallywag! Begad! T' airframe is paper tube with Public Enemy's signature yellow glassine coverin' it. T' motor mount is paper too. Begad! Blimey! T' fins are 1/8" plywood and include tabs t' go all t' way through t' t' motor mount. Ya scallywag! T' centerin' rings are made from press-board type material that is quite strong and accepts epoxy readily. Ya scallywag! T' nose cone is plastic in t' line o' LOC/Precision nose cones. Ahoy! Aye aye! 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! I don't like, me bucko, shiver me timbers, or use bungee for recovery, but t' strap nylon is nice. Begad! Two 1/2" copper launch lugs are also included and they're already angle cut t' reduce drag. Well, blow me down! T' parachute is a 36" LOC/Precision type flat chute and is fine for sea level launch sites, ya bilge rat, but too small for us highlanders.

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

Finishing:
Finishin' a fiberglass rocket is relatively easy, but time consuming. After sandin' I shot 2 coats o' Plasticoat Truck primer that I got from Pep Boys. Aye aye! I sanded betwixt coats with 150 grit, then 400 grit paper. Next I added three coats o' flat white Krylon, sandin' betwixt each coat, ya bilge rat, lightly, with 400 grit sand paper. Ahoy! Finally I added 3 coats o' Red Devil paint (Orange Creamsicle and Gloss Black). Blimey! Avast! Came out nice, shiver me timbers, 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, ya bilge rat, ya bilge rat, and twice in it's primer gray. Each time it be a great flight. T' H123 doesn't get it too high. Avast, me proud beauty! T' I161 is middle high with lots o' smoke. Well, blow me down! An I211 is a real shot and quite high. I saw Roy Wied's Psycho fly and it flew like it was on rails too, me hearties, so I think this is part o' t' rocket's normal characteristics.

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

Flight Rating: 5 out o' 5

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

Overall Rating: 4 out o' 5
