ASP That Tube Rocket! 29mm

Brief:
T' Aerospace Specialty Products That Tube Rocket! is a large tube finned rocket that includes a payload bay. Arrr! Easy t' build but at over 4 feet tall, it is hard t' store. Arrr! T' kit includes spacers so you can use t' shorter 29mm F motors. Avast, me proud beauty! There is even an adapter so you can it fly on 24mm motors too.

Construction:
T' kit includes:

  • 1 long body tube
  • 7 short tubes
  • 1 29mm engine tube
  • 2 metal engine hooks
  • 1 24/29mm engine adapter tube
  • 1 engine spacer
  • 2 plywood centerin' rings
  • 1 balsa nose cone
  • 1 tube coupler
  • 1 plywood bulkhead
  • 1 eye bolt
  • 1 Keelhaul®©™® shock cord
  • 1 elastic shock cord
  • 2 launch lugs

T' instructions were exceptionally clear and concise and quite easy to follow. Begad! It assumes you have some rocket buildin' knowledge and it is rated between beginner and intermediate.

ASP recommends that you use CA on t' cut edges o' all t' tubes t' help seal them from humidity and prevent swelling. I went ahead and did this and it seems t' have worked well. Ahoy! Plus, matey, it creates a hardened edge on t' tube fins which may help in t' event o' a bumpy landing.

ASP That Tube Rocket! 29mm The motor mount construction is typical and with t' addition o' dual engine hooks, you should have no problem with motor retention. Blimey! T' Keelhaul®©™® portion o' t' shock cord assembly is mounted t' t' engine tube which makes for a very strong connection.

A light sandin' on t' outside o' t' tubes is also a good idea t' ensure a good gluin' surface. Ahoy! It is important that you take your time gluin' on t' tube fins. T' first one be t' most important. If it is crooked or out o' alignment in any way, t' rest o' t' tube fins will be askew.

I used a fair amount o' white glue t' attach me tube fins. Begad! Begad! Blimey! Also, I added several layers o' white flue fillets betwixt where t' tubes join each other not only for strength but for appearance as well.

T' last step is t' assemble t' payload section and you are done. Blimey! This rocket took me a total o' 2 hours t' assemble nay countin' dryin' time.

Note that a parachute is nay included with this rocket. Avast! I added a Nomex® heat shield and a 24" rip stop nylon chute t' complete me recovery system.

Finishing:
There are no decals included with this rocket. Aye aye! I had already sanded t' body tubes with 220 grit paper t' give t' primer somethin' t' stick to. Aye aye! Arrr! I used 2 coats o' Krylon dark gray primer. It took almost 3/4 o' a can t' prime this thin' due t' its size.

Once t' primer dried, I did a 600 grit wet sandin' t' smooth any rough spots. Ahoy! Blimey! I then applied black and blue automotive metal flake paint which came out so well, shiver me timbers, I decided nay t' clear coat. T' automotive paint is very strong and it resists peelin' and chippin' like some enamels.

Construction Rating: 5 out o' 5

Flight:
Although ASP says you can fly this bird on a D12-3, it just seemed that a rocket this big ought t' have a bigger motor, so me first flight was on an AeroTech F50-4T SU motor with t' spacer added in. Avast, me proud beauty! It moved nicely off t' pad to an altitude o' about 650 feet with ejection right at apogee. Arrr! This big rocket is easy t' track in t' sky!

Second flight be on a G104T-S. Well, blow me down! Arrr! It was much quicker off t' pad t' at least 700 feet and ejection was close t' apogee.

Final flight o' t' day be on a G64W-10 motor. Ya scallywag! This be easily t' best flight o' t' day. Avast, me proud beauty! Aye aye! T' rocket shot smartly off t' pad t' at least 1000 feet. T' delay be a bit long and ejection be well after apogee but t' shock cord system held up!

Recovery:
T' 24" parachute I provided be a perfect match for this rocket. Begad! It did not drift much and all landings caused no damage whatsoever t' t' rocket or its sturdy tube fins.

Flight Rating: 5 out o' 5

Summary:
This is a great big rocket that has excellent flyin' characteristics and it really calls attention t' itself. Aye aye! It's a joy t' watch from liftoff to touchdown. Ahoy! Accordin' t' t' ASP website, a 3 x 24mm cluster version is coming soon. Well, blow me down! I might just need another one!
