Brief:
Art’s latest product line be t' Hourglass. Blimey! T' Hourglass rockets resemble spool rockets. Avast! Begad! They have top and bottom circular plates with two cones between the plates providin' t' hourglass shape. They are currently available in 13mm, 18mm, ya bilge rat, and 24mm sizes with all sizes comin' in several colors. Begad! Aye aye! This review is for t' 24mm versions. Avast! T' shorter version uses Estes D12 length motors and the longer version uses t' E9 length motors. Ahoy! Both will fly on most anythin' that will fit.

Here are t' specs:

Construction:
These use t' same paper and foamboard construction like t' rest o' Art's products. Aye aye! Both sizes include:

• 1 sheet o' pre-printed cardstock
• 1 small rectangle o' foamboard
• 1 24mm motor tube
• 1 steel motor hook
• 2 pages o' instructions

Tools and supplied needed include:

• Scissors
• A new #11 X-Acto blade
• Elmer’s white glue
• Cellophane tape
• Spray-on clear coat

Construction was simple as expected. Ya scallywag! Arrr! Blimey! You cut and form t' cones, shiver me timbers, glue the plate patterns t' t' foamboard, cut them out when dry, install t' motor hook, and glue all t' pieces together. That’s it. Arrr! T' only two things t' watch out for is t' keep t' plates parallel t' each other and t' make sure the launch rod holes are all aligned.

Finishing:
My Hourglasses used colored cardstock so no real finishin' is needed. T' short version is day-glow orange and long is day-glow green. Avast, me proud beauty! Arrr! If you want t' paint them, matey, Art recommends sealin' t' exposed edges o' t' foamboard with white glue. Aye aye! Ahoy! He also recommends sealin' t' whole thin' with clear enamel t' make them moisture proof. I used clear acrylic. Begad! T' clear coat also gives them a nice shiny finish.

Construction Rating: 5 out o' 5

Flight:
I flew t' short version on a D12-0 and t' long on an E9-P. Begad! Both had t' same flight profile but o' course t' E9 version went higher. Aye aye! Both tore off t' pad like t' proverbial bat. Aye aye! After burnout near t' top o' t' flight, shiver me timbers, shiver me timbers, it be clear that they were spinnin' wildly end-over-end. Begad! Since t' boost was fast and straight, me hearties, I assume t' tumblin' started after burn-out, but I can’t be sure since they were so quick. Begad! Arrr! Either way, t' crowd loved them!

Recovery:
Both tumbled in nice and slowly. Ahoy! Blimey! Blimey! Blimey!

Flight Rating: 4 out o' 5

Summary:
These are easy t' build (as usual) and if you like Art’s cones, shiver me timbers, you will probably like t' Hourglass series. If you like spool rockets, you will also like them. Avast! T' flight profile is a little different than a saucer. Avast, me proud beauty! They don’t slow down as smartly and are totally unstable after burn out. Begad! They are however, arrr, at a very respectable altitude at this point and keep goin' it a generally upward direction, shiver me timbers, so this condition appears t' be a feature nay a bug.

Overall Rating: 4 out o' 5
