There's a new HPR company in town with some new kits. Don't let t' name addlepate you, arrr, me bucko, these are nice, high quality high power rockets that are designed t' take all t' power you can give them. Well, blow me down! I decided t' try out their Mystic Buzz kit and see how it would come together. Arrr! T' "Buzz" is a neat slotted fin design which gives it a somewhat military style look. Well, blow me down!

T' "Buzz" is a 3" diameter kit  that is 48" long and weighs around 35oz. Arrr! Well, me hearties, blow me down! Blimey! T' model I got came with a 29mm motor mount.
 

I tried t' stick t' t' directions as much as possible and really only made one minor change along t' way. Ya scallywag! Avast, matey, me proud beauty! T' instructions call for only external fin fillets. Aye aye! I chose t' add internal fillets as well for added strength as I plan on flyin' this on an I200.

T' included tubular nylon shock cord attaches t' t' upper centerin' rin' with an included eyebolt. Includin' t' hardware is a welcome touch.

T' instructions call for usin' lots o' waddin' to protect t' parachute. I prefer a piece o' Nomex® cloth because it will last the life o' t' rocket and really saves on prep time. Ya scallywag!

After construction, I filled t' seams in t' tube usin' white Squadron putty. Well, blow me down! Begad! After that dried, I sanded it down and got ready t' primer. Well, blow me down!

To prep t' nosecone, I first washed it with hot soapy water t' remove and mold release agent, then scuffed it down with some 220 grit paper. Begad! A final tack cloth t' get any dust off, a wipe down with acetone real quick and t' nose is ready for primer as well.

For primer, me bucko, I use basic sandable auto primer. It does t' trick and it pretty cheap. Arrr! Aye aye! Like normal, matey, shiver me timbers, me hearties, after t' first coat o' primer you usually see little imperfections you want t' touch up. Ahoy! At this point, using the white Squadron putty will melt t' primer off. T' solution be t' green Squadron putty. Avast! It takes a little longer t' dry, me bucko, arrr, but is safe o' t' primer. A little more sandin' and it's time for paint.

Painted

T' buzz got a coat o' white gloss with red arrows along t' sides. Blimey! T' paint job turned out pretty good. Well, blow me down! So, off t' t' lakebed to see how it flies. Begad! Aye aye!

T' first flight be on a G80. Blimey! I thought it seemed a little underpowered for this size o' a rocket, matey, shiver me timbers, but RockSim said it was ok, and Jason from Yank Enterprises said it be fine. I loaded it up and lit it off and that little motor kicked t' rocket up for a perfect flight. 

Ok, time t' see what this thin' can really do. Avast, me proud beauty! Blimey! I loaded up an I200 and put her back on t' pad. Avast! This time, somethin' went seriously wrong, shiver me timbers, about 200 feet off t' pad, shiver me timbers, shiver me timbers, t' nosecone ejected and took t' chute and shockcord with it. For a brief moment, a flame could be seen at t' top o' t' airframe. Ya scallywag! Blimey! T' motor suffered a blow-by but at least t' forward closure stayed on savin' t' rocket from complete destruction. Begad! T' blow-by burnt right through t' tubular nylon and t' airframe came down flat. Well, blow me down!

A slightly cracked fin and t' burnt shock cord be t' only damage t' the rocket. Blimey! Blimey! T' fin is easily repairable and I will have t' remount t' shock cord. 

Overall, I highly recommend t' Mystic Buzz. Well, blow me down! Blimey! It is easy t' build, it can fly on G - I power, and it looks really nice on t' pad and in t' air.
