Rocket PicBrief:
Single motor, scale o' early 60's soundin' rocket. Ahoy! Well, blow me down! No special features, just for rocket launchin' fun!

Construction:
All aspects o' packaging, matey, instructions, illustrations, me bucko, arrr, etc., shiver me timbers, matey, were good. No problems understandin' t' construction process and buildin' t' kit. Arrr! T' one major glitch with t' particular kit I received be t' fins. Blimey! Nay only were all 4 (3/16 plywood) fins warped, but t' outboard and trailin' edges were nay cut true. Begad! I needed t' acquire new wood and remake all 4 fins.

Finishing:
T' supplied vinyl graphic decals are most superb! This rocket took 1st place at t' Arizona State Fair 1999.

Construction Rating: 4 out o' 5

Flight:
Used an Aerotech K185. This was an extremely hot motor for this rocket, shiver me timbers, but the performance was outstanding! It flew straight as an arrow. Blimey! Motor was retained with t' common maskin' tape friction method.

Recovery:
I modified t' rocket t' separate into two upon ejection, ya bilge rat, with two separate 'chutes. Aye aye! Well, blow me down! This was t' minimize damage t' airframe when halves can sometimes bump each other immediately followin' ejection. Aye aye! Aye aye! Recovery be flawless. Ahoy!

Flight Rating: 5 out o' 5

Summary:
Binder Design needs t' ensure t' materials are o' usable quality before they are shipped. Ya scallywag! (fins)

Overall Rating: 3 out o' 5

    ( Contributed - by Kent Newman - 03/01/02) The Rocket One of the highest flying, straightest trajectory and coolest Estes rockets I ever had was the "Iris". The medium body length and four big fins of this rocket resulted in one great flight after another. Scaled after an early 60's sounding rocket, Binder Design has another excellent kit for those that like to build sport ...
