Another case of "When good designs go bad"...

The RENEGOON...

Length: 10.82"
Fin Span: 8.14"
Weight: 1.77 oz

A8-3......146'......16 FPS
B4-4......375'.......6 FPS
B6-4......381'.......5 FPS
C6-5......846'.......3 FPS

Model has 1/4 oz ballast to reach >1.00 margin, and safely reaches flight V in the length of a 36" standard rod, 1/8" dia.

Enjoy!

BARCLONE is certainly not exempt from the Goon Squad Makeover Team...

Behold -- the Goonender!

Performance was not spared in this design, it was completely thrown out the window. You will need to reef the chute when using the C6-3 due to the excessively high deployment V. No ballast is required to achieve stability. All motors reach flight V in the length of a standard 36" rod, 1/8" diameter.

Length: 10.625"
Fin Span: 6.64"
Weight: 1.3 oz

A8-3......175'......13 FPS
B4-4......365'......19 FPS
B6-4......365'......16 FPS
C6-3......697'......31 FPS

Enjoy!

Lil' Battle Axe has a fat cousin...

Length: 11.64"
Fin Span: 4.46"
Weight: 2.12 oz

B4-4......330'.......9 FPS
B6-4......330'.......5 FPS
C6-5......855'......15 FPS

The A8-3 is not recommended. All three motors reach flight V in the length of a standard 36" rod.

Enjoy!

I like these open-style fins, and have tried to use this idea since doing Lil' Battle Axe. It's interesting how the outer edges of the fins seem to have the lion's share of the stability attributed to them, while the inside area of the fin just adds extra weight (and, granted, strength). Use the SEMROC 20" parachute if the recovery area is large enough, but drop down to the 16" parachute when the area is smaller. You should have enough canopy area to keep the landing loads on the fins low...

Reinforce the outer surfaces of these fins with some label stock, or use regular computer paper attached with glue or 3M-77 spray adhesive. Once the paper has been sealed to the wood, you shouldn't have any trouble with the paper trying to lift.

The forward "fins" are just balsa supports for 1/8" diameter wood dowels. Epoxy these joints. Trim the front and rear ends of the dowels to match the angles of the supports.

Length: 24.98"
Fin Span: 4.95
Diameter: 1.04" (ST-10)
Weight: 1.77 oz

A8-3......160'......13 FPS
B4-4......385'.......7 FPS
B6-4......391'.......3 FPS
C6-5......825'.......9 FPS

All motors reach flight V in the length of a standard 36" rod.

Enjoy!

Great design of the Star Seeker Craig!

I still have not figued out how you did the hollowed out fins. I keep getting the message WARNING: Plan contains one or more crossed lines every time I try it. Please explain how you crossed over into the middle section to hollow it out??

I also see your landing troubles with these delicate fins. In my design notebook I once had an idea for a landing post (3/16" or 1/4") dowel which was glued onto the main BT and stuck out past the fins bottoms. The idea of the post is for it to take the brunt of the impact on landing and not the fins. Might be somewhat unsightly though and needs to be kept out of the exhaust stream also. Just an idea.

You have to zoom in as close as the program will allow on the plot screen, and move the various points as close as possible, without allowing any of the lines to cross each other. Think about having the full width of the plot screen as being less than one grid square. It will make this task much easier.



One could probably glue a strip of basswood along the trailing edges of the fins to reinforce them, then fill and sand to shape...

Just a simple little design from my journal I thought was kinda neat. Might just be a Park Flyer as well. I have a rare day off today while we are waiting for materials to show up on the jobsite. Very rainy today as well so outside yardwork is put off. My choices seem to be either pay the bills or build some rockets . Not a hard choice for me, rockets win.

Enjoy and Thanks Again, JP

I just created a spreadsheet listing all of the BARCLONE rocket plans that have been posted either to the website, or to the forum. This list includes everyone's contributions, not just mine. There may even be a few missing from this list which I've forgotten about, or which are just not ready to be acknowledged. The list does not include accessories or other rocketry items.

The list currently stands at 227 plans, with RKT files for every one of them, and PDFs for a few of them. Now you know why it's taking some time to create that catalog...

I once mentioned that I thought the number had crossed 250. Not quite there yet, but we're slowly reaching that milestone.

I really want to thank all of you who have contributed to the BARCLONE catalog of designs. These may not all be the fresh and exciting designs you wanted to see, but such designs come as part of the territory, not the whole landscape. We have some very simple designs, which I still contend everyone flies more often. But among these are also some very cutting-edge and complex designs that keep this hobby interesting.

Until later...

Here's plan #228...

Another open-fin style, with very good performance. Similar in configuration to the Estes Clipper -- simulated two-stage, large sustainer fins, smaller booster fins.

Length: 22.2"
Fin Span: 5.04"
Diameter: 1.04" (ST-10)
Weight: 1.42 oz

A8-3.......194'.......4 FPS
B4-4.......463'.......8 FPS
B6-4.......470'......12 FPS
C6-5......1000'......13 FPS

All motors reach safe flight V in the length of a standard 36" rod, 1/8" dia.

Enjoy!

Craig,

Neat design!!
