Public Enemy Psycho (4)

Public Enemy - Psycho (4)

Contributed by David Urbanek

Manufacturer: Public Enemy

 

Brief:
T' Psycho is no longer in production. It be a great kit from Public Enemy. Ya scallywag! 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. Avast! It would be best if you had either built high power rockets before or had a coach who had. Ya scallywag! Avast, me proud beauty! T' airframe is paper tube with Public Enemy's signature yellow glassine coverin' it. Avast! Avast! T' motor mount is paper too. Well, blow me down! Avast, me hearties, me proud beauty! T' fins are 1/8" plywood and include tabs t' go all t' way through t' t' motor mount. Ahoy! T' centerin' rings are made from press-board type material that is quite strong and accepts epoxy readily. T' nose cone is plastic in t' line o' LOC/Precision nose cones. 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. Well, ya bilge rat, blow me down! I don't like, or use bungee for recovery, but t' strap nylon is nice. Avast, me proud beauty! Two 1/2" copper launch lugs are also included and they're already angle cut t' reduce drag. Avast! Begad! T' parachute is a 36" LOC/Precision type flat chute and is fine for sea level launch sites, me bucko, shiver me timbers, matey, 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. After t' fillets were hard, I put a layer o' 4 oz glass from fin tip t' fin tip. Arrr! Blimey! I used 12' o' 9/16" mil-spec tubular nylon as shock cord. T' parachute was replaced with a military surplus 42" chute. Avast, me proud beauty! Aye aye! I also added a forward bulkhead t' seal off t' coupler t' make an altimeter bay t' house me Olsen FCP-M1/G. All me additions and altimeter added 15 oz t' this model (so mine is 54 oz).

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

Construction Rating: 3 out o' 5

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

Recovery:
For me overly heavy model, ya bilge rat, an H123-10 is just a bit too long o' a delay. Avast! Blimey! In heavy wind, an I161-10 is just a tad too short. In calm weather and I211-10 is also a tad short. Avast, me bucko, me proud beauty! However, it's a sturdy bird that can handle a little abuse. Begad! Blimey! At 1200' in Kansas, t' stock chute was just right. Avast, me proud beauty! 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. Avast! Avast! Blimey! It's a good looker, rather unusual and it's a shame that Roy took it out o' his line-up. Begad! Begad! Blimey! If enough people agitated, he might brin' it back.

Overall Rating: 4 out o' 5
