Greg,

I did not know you RCGrouped. :-) Welcome to the show. Greg inspired me to build a Bubble Dancer.

Bob, good idea on this. I have often wondered how many Bubble Dancers have been built. Here is “Johnny Rotten”. He is gone but he’s not forgotten.

Guess it's my turn!

Just had a blast yesterday spec'ing out my BD a few times up in Maryland. I forsee a trip to California in my near future, so I just might have to test out some of those legendary west-coast thermals...

Pictures though, back to the point.
I have a lot of construction photos here: http://www4.ncsu.edu/~djedward/planes/bubbledancer/bubbledancer.html

Dan,

Very nice job! I remember seeing some of those pictures as you built it early on. Very cool.

I also like how you used different colors on top and bottom. I did that on my Allegro and like it quite a bit.

Ryan

[danstrider]

Good to come across you again Ryan. Glad you got to see the full-circle :-) I have looked at your pictures a time or two myself!

Neat to see you again Ben! Nice to see you stuck with Drela and super-sized the Allegro we talked about a couple years ago in Wilson at the DLG contest.

Yup! Apparently I did well enough with the Allegro-Lite, Denny tapped me to build and document the EZBD build. Check out the documentation if you get a chance :)

[soarrich]

Uses AG35 on the mainpanel, AG35-7 on the tips, 1/2 inch cf tube in center and 3/8 cf tube for spars in the tips. Great flier, thanks MD.

[skipinhouston]

I don't have my Bubble Dancer from Mississippi yet, but I do have a home (hangar) for her to live in when she gets here.
Its Baltic birch 1/4" plywood.
Still needs several coats of urethane, internal supports for the fuselage and wings, some brass handles on the side, and foam on the inside, but you can get the idea from these pictures.
Yes, I know. It looks like a freaking coffin, but it will protect the airplane and make people wonder when I drive by.
Thanks Mike Browne for the use of your table saw, planer/joiner, and help.
He said I should have done dovetailed joints but I told him I didn't have the skill level to build piano's.

This plane was built using the original composite airfoil, rather than the flat-bottomed compromise airfoil. It flies well. Our club has 3 BDs and several commercial variants (Ava, Danny, Soprano). This one has a better LD and flies faster. It weighs 48 oz., only a few oz. more most of the built-up BDs I've seen. Around here, they all require ballast most of the time anyway.

[neonbutterfly]

tony, where did u get the fuse for ur BD???

bob

[tonyestep]

Hi Bob,

I got the pod and boom from Barry Kennedy. That was 4 years ago, so I dunno if he is still selling them separately. At about the same time I bought Ava #8.

I got the V-mount from Bud Elder.

The pushrods are stainless fishing leader, run in teflon tubes on the outside of the boom. The spars in wing and stab use the same carbon specified in the built-up BD plans; the cores are blue hi-load.

[Roger_n_MtAiry]

126" version, otherwise according to Mark's plans. Bud Elder's pod & mount with boom from PoleCat. CF pushrods, 750 mA NiMh, 555 with three of the servos that Mark specs for the spoiler with metal gears. Despite best efforts, I missed the weight goal. It came in at 41 oz. :confused: but it really does fly great. I am very pleased. I will give it (me) a good challenge at the CASA Open in Sept. :cool:

[ASK]

My son Fateh Singh and I built this in Summer of 2003, and maidened it three years ago today. Fond memories, and it still flies great.

Some favorite photos.

Here's a picture of two at a time: mine and Harold Mantz's beautiful built-up BD.

[dharban]

My BD's #1 and #2 (I'm flying BD #2 1/2 now)

[tonyestep]

DHarban, that's a sexy-looking fuse on #2. Tell us more about it. And I like that Ava-style stab, too.

[dharban]

There are more details on the Allegro web site in the Files section under Carbon BD fuselage. There are also some additional photos in the Photo section.

The stab construction is straight forward and simple. It really isn't any harder to make a AVA type stab than a conventional one. I have construction photos somewhere and I'll try to post them.

[Roy Walton]

Here is mine - I guess it is modded to something other than a Bubble Dancer.

Roy

[Mark Miller]

Here are two photos of a very special BD. It was built by Mike Remus. These photos were at the 2005 NATS. Mike was suffering from cancer at the time and passed away shortly there after. I own it now.

I've seen Don's work. His fuselages are something to behold... in fact all his work is quite beautiful. He went crazy and moved to Tulsa, though... I do my best not to hold that against him.

Here are two photos of a very special BD. It was built by Mike Remus.

That is a special plane and Mike was a special guy. I timed for him when he was flying that BD at his last ever OVSS contest (2005 BSS MID AM). I knew he was feeling rough by then but he soldiered on and had a good last round and took 3rd place "wood" in RES.

I'll be there, but without the Allegro-Lite. Hi Phil! For those following along, that's Phil Lutz and his Allegro-Lite alongside our Bubble Dancer in the photo above, post 17.

Yes, I'll be at the Southwest Classic (http://www.public.asu.edu/~vansanfo/casl/). This February contest in Phoenix AZ is a good chance for all you folks to get away from harsh winter weather, and fly your Bubble Dancers in a big contest. I'll have the BD and (speaking of Dr. Drela's designs) hope to have a couple prototypes based on the Aegea II.

The BD will have a new plan-style fuse, which is considerably lighter than that strong and beautiful AVA fuse we've used for years.

[rdwoebke]

This February contest in Phoenix AZ is a good chance for all you folks to get away from harsh winter weather, and fly your Bubble Dancers in a big contest.

Some day I hope to make it to the SWC. Perhaps in 2008. I actually wonder if the Allegro would be the best thing for me to bring due to it being a bit smaller and easier to airline transport.... Anyhow, I'll just have to go out and fly in the cold that weekend as a nod to you all enjoying the Arizona weather. Good luck from Santa Claus, Indiana to all the BD pilots competing in SWC!

[Desert flier]

I have built both Alegro lite and now a Bubble dancer I hve put a .25 glow on it as I have no winch as I live in a small town and there are only two RC guys in town and I did not have $300 to spend on electric. Flies great and lands at a walk the rubberbands will be removed when i get the right cg The fuse was built on the looks of a giant butterfly. Just a great glider. :) :) :) :)

[aeajr]

With those modifications, I wonder if you can still call it a bubble dancer? Looks like no spoiler, and a standard tail.

I assume you know you don't need a winch to launch it. Hi-starts work great!

Glad you are enjoying it.

[soarrich]

The wing is the thing, it's cool.

[rdwoebke]

He can call it whatever he wants, me thinks! :-) That, and the wing looks pretty much to plan. I think he does have spoiler (that would be the big red line in the center of the center section), he just has the wing banded on for the first few flights. I'm sure I'll never make it to your town in Australia, but I'd be interested in seeing a BD land on wheels... :-)

Fun looking ships. People don't get enough credit these days for being unconventional and doing thier own thing.... :) I like the canopy on your Allegro... So if we are posting Allegros to the BD thread, here is mine! :-)

[Desert flier]

Thats what i enjoy taking off from the ground in no wind and landing doing touch and goes It looks great as the tail leaves the ground and just lifting off into the air. The wings are built to plan with carbon art short kits. Both have spoilers. Will try and get some video soon and will post the landing and takeoff when i do.

[soarrich]

Maybe someone else will know better, but I would think that if you're going to be launching with a motor you could leave out all or most of the CF to save some money. I think the spars out of wood will handle any flight loads, the CF is the for the launch.

[flystoolow]

...the CF is the for the launch.

No, it's the CF sandwich that's for lunch. :D

[Desert flier]

Yes you are probably right but I have seen light park flyers snap wings and my spad also since i am building it from scratch it is not much money or time to make the carbon caps and binding it is very relaxing to know that the wing will never fold no mater what. Have not done any dive test. will wait untill the wing is securely bolted on

[flystunt]

Hey everyone,

I am just starting a BD build with the usual starting pieces (Bud Elder pod and mount, laser arts ribs, tailboom, CST carbon, etc. As I am laying out the ribs and webs I am still undecided as to which span to pursue. Any ideas from you all who have already gone down the Dr. Drela path? I am currently flying a Soprano (which I absolutely love) and am looking to round out the stable with a lighter lift floater that turns like a sports car. Will the 126 span significantly reduce the turn ability of this ship?

I am really looking forward to the build and learning some new things with composites. I have an excellent stash of really light contest wood and this should be fun trying to hit the spec'd weights.

Sean Elliott

[rdwoebke]

Will the 126 span significantly reduce the turn ability of this ship?
I built the 126 inch version. I'm not sure what signifigant is. I know the BD turns nicely. I doubt most of us would really be able to tell the difference between the 2 spans, to be honest.

Ryan

[flystunt]

Thanks Ryan for the thoughts on the negligible difference. Maybe I will go with the longer span.

Sean

[pocket rocket]

built the wing from a Laser Arts rib set a couple of years ago and it has flown as an electric with a K2 light (V-tail) fuselage and as a glider with a Chrysalis 2M (also V-tail) fuselage

at long last I now have a more appropriate Art Hobby High Aspect fuselage as in the photo so maybe it's a Bubble Dancer now and not a K2Bubba nor a Chrysabubba maybe a Bubble Aspect or a High Dancer ???

maiden flight went well with 16 minutes in cold and windy, but with thermals, Tucson air

Nice, Philip.
Are you bringing it to the SWC to compete in RES? I should have mine, and then we can dance them around in the same sky.

[Desert flier]

Hi just a quick question When I pull the spoiler the nose pitches down a fair bit and gaters speed quite quick I have nearly full up elevator mix and still needs more I am thinking i may have to reduce the spoiler throw any ideas from other Bubble dancer pilots

[rdwoebke]

Hi just a quick question When I pull the spoiler the nose pitches down a fair bit and gaters speed quite quick I have nearly full up elevator mix and still needs more I am thinking i may have to reduce the spoiler throw any ideas from other Bubble dancer pilots

You need quite a bit of up elevator mix with full spoiler. The TE of the elvevator might move an inch or an inch and a half. Check your servo travel to make sure you have a good deal of travel, and then see what your mix is at. On my Allegro/BD, I found that once I had the mix set right though, this thing is a dream to land.

BTW, test the mix up high and if you are able to access and make changes to the mix while the plane is in the air, you can usually get it sorted out in a few flights.

Ryan

[bobby legue]

Perhaps if you cant get enough elevator you could limit the spoiler height. I know its a back door approach but it is a viable second approach.
Bob

[rdwoebke]

That would be a back door approach, but I have to figure if a person spent all the time to make a Bubble Dancer that I'd do whatever possible to get enough elevator throw to make it work. It really is sweet when it is working.

One thought I just had. Desert, you have a segmented elevator on your BD, right? Not sure how that will effect things or if you will need even more throw on your elevator (compared to how it looks on our full flying V mount tails).

Ryan

[markdrela]

Perhaps if you cant get enough elevator you could limit the spoiler height. I know its a back door approach but it is a viable second approach.
When the elevator servo is mechanically centered, and the stab is at neutral, the elevator horn should be angled forward about 15 degrees. In effect, this makes a longer elevator pushrod. See the BD fuselage drawing at CRRC.
This biasing of the elevator servo like this gives more total up-elevator capacity, so you don't run out of up-elevator even with lots of spoiler compensation.

[balsabozo]

Hi Folks, beautiful ships!
Jumping in here with question as I continue my search for my second TD plane:

Roy Walton and Philip Pocket Rocket, How does the BD/wing fly with a Vtail?
Is the Vtail effected by the deployed single spoiler?
Any tips on design? did you scratch build it? If so, any insights, esp sizing?

[glderguy]

I was out flying with one of my flying buddies last week, Bob Brown. He has built a beautiful stretched wing, 144 inch Bubble Dancer. Great flying plane and can really cover some ground. Ill get a pic of it next time we fly together.
Walter

[Roy Walton]

balsabozo

I have flown both BubbleDancer and AllegroLite with "V" tails. Both respond with excellence when the spoiler is fully deployed. Both require only about 12% of "up" elevator as spoiler compensation.

Having built and flown Dr. Drela's standard versions of both planes and then with "V-Tails", I find I prefer the handeling of the "V". Just my opinion . . . .

Stab Size per side = 7 1/2" root, 17" length. The taper is to 5 1/8" at 11 1/2" from the root. 110 degrees. Moving surface is 2 3/4" root and 2 1/4" tip. The hingeline is at right angles to the fuselage.

Here is a rough drawing.

I have also used an ArtHobby fuse and tail with an Allegro wing. Actually have 2 AH fuses and the one Allegro wing, one regular and the other electric. If you are seeking a fuselage (and tail) for your BD wing you might check the ArtHobby site to see if anything looks the correct size. I used built up balsa, ply and tailboom for both my Bubble Dancers.

Roy

[Desert flier]

thanks for all the ideas :)

[slozuke]

Other than the Art Hobby fuses where else can you get a fuse for the BD?
I know Denny@Polecat Aero is kitting the EZBD so he might sell fuses but I don't see them on his website. What other fuses are available?

Bud Elder I think makes a fuselage.

You can buy an Ava fuselage.

There might be more also, like perhaps Mike Lawkowski would sell one.

Or you can build your own (that is what I did).

Ryan

[kak8]

I have a question for ASK

How did you cover this blue and red (curved) wing tips? Isn`t it difficult to controll the shrinking film to get a clean lines?

Or did you paint on the covering film?

[soarrich]

The question wasn't addressed to me, but you might want to look at this guy's site, quite the builder....

Wow! the wings didn't evenflex on launch! :^)

Reminds me of my Piece o' Cake.

Cool.

[tonyestep]

Here's a pic of a built-up BD built by my clubmate, master craftsman Art Frost. He flew it in last weekend's club contest, and won RES with it.

It's covered with low-temp Polycover from Hobby Lobby, which works well. We refer to the color scheme as the flying Creamsicle.

It came out at 40 oz. RTF, but Art hated the way it flew and added 13 oz. At 53 oz. it flies completely different and is a dynamite plane.

looking good mike... can't wait to get mine all together.. looks like i won't be finishing it until after i get back from North Carolina... oh well.. i should still have her in the sky before the end of june! ;)

I hope you guys chose different colors so you cantell them apart.

[mlave36399]

Here are a few more pictures of my Bubble Dancer (i hope the Pics are attached)

[AllThumbs]

That third picture there is beautiful...looks great!

So, ...these days, if one wants to build one...what or who do we need to see ?

Are these all group projects?
Are components available?

[tonyestep]

Get laser-cut parts from Mountain Models:
http://www.mountainmodels.com/product_info.php?cPath=25_30&products_id=189
and get plans from the Charles River site. Best is to get the .DXF files and have them printed full size. Then get the carbon, kevlar thread, etc from Aerospace Composites or CST. Set aside a little time; it takes about 200 hours to build one. You can cut a lot of time out of this by getting the pod and v-mount from Bud Elder, and the boom from Denny Maize (www.polecataero.com). You can cut out even more by getting an EZBD kit from Denny if they are available (last I heard, they were not).

[Desert flier]

Yes i built my BD wing from a short kit from laser art and downloaded the plans on my computer and glued/taped all the pages together not the best way but it did work for me this glider is just a pleasure to fly I now plan to get a vario to take it to the next level

[mlave36399]

Thanks for the compliment it sure is a gratifying project. lots and lots of sanding. it was pretty windy that day that I maidened it (the third picture) 12-18 MPH flown with no balast. Later one of the other guys in the group build said to me i thought you were crazy to fly it it this wind but if your crazy enough to fly it I'm crazy enough to watch. but it did fly great and as a benefit looks great too.

[tonyestep]

I had to paint over some repairs in the center section of my aging BD (it's going on 7 years old now). I got to fooling around with my airbrush, and next thing I knew......

[petefly58]

Finally have my Bubble Dancer almost completed. Started it in Jan of 08. All that remains is to install the radio and servos and balance. Quite a project!

Pete

[petefly58]

Got my Bubble Dancer into the air for the first time today despite breezy and cold conditions. A few hand tosses showed that CG and throws were in the ballpark, then a couple of winch launches. Hit some lift on the 2nd launch, she indicates very well. She will be great in light conditions! Thanks to Mike and John and my other buddies for helping me out today! First flight gitters, there's no other feeling quite like it.

Pete

[atjurhs]

Well today I finished all the major construction of my BD wings today. They span 126inches and currently weigh 20.5ounces (without the spoiler servos). It was the most challenging open-bay build wing that I've done, particularly because of the "carry-through pieces". I plan to marry these wings with a HoustonHawk (Condor) fuselage. My total RTF target weight is 45ounces, that's certainly heavier than a traditional BD.

Next time I build a set of these wings, I'll connect all the "carry through pieces" before I sheet the D-Tubes.

[neonbutterfly]

skycruiser,
which spinny thing did you use, and are you happy with it? I'm considering the same on my build...

PM me if you want to keep off topic posts off of here.
Thanks, Mark

[Skycruiser]

Hey, Mark. I used a BP2915-5Y from Hobby City. Very happy with it, not the most efficient motor according to predictive software, but only 750 Kv so it'll swing a big prop. I'm running an Aeronaut 13x8 which was pulling 23A from memory on 3s2p3400. On the 3sA123 it would have to be down to about 20A, so I could go up a bit in prop size if I want, but I actually like the climb as it is now, about 45 deg. On the lipos it was pitching up too much under power and it was tricky to keep an even climb going. Once again, I build a plane with not quite enough downthrust!

So yes, very happy with the motor, nice and quiet, and a steal at $24. http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=667&Product_Name=TowerPro_Brushless_Outrunner_2915-5_750kv_/_507W

Nick

How much did you use? How much do you think you need?

[Skycruiser]

Soarrich, I just put in about 3mm on the TLAR basis when I made the foam pod. I think it works out to 3 deg or so, could really do with an extra 1 deg

Marc, I used the Turnigy Plush 40A (http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=2165&Product_Name=TURNIGY_Plush_40amp_Speed_Controller) from the same place. It has a 3A BEC which gives theat extra bit of confidence. Nice smooth esc, and dead easy to program with the program card.

I am starting to get excited about building a guppy fuse upscale to fit my Bubble dancer wing and using the carbon sock to strengthen it all and finaly get rid of my glow motor and go brushless what setups have others used ?

[neonbutterfly]

desert flier.....i have a homemade balsa, glass fuse for my elec BD...it's a little wider and longer than a glass fuse but it fits my axi.....here is my set up and the plane is at 600 feet in about 20 seconds...auw is 53 oz.

axi - 2820/10
castle - thunderbird 54 amp esc
cam - 12x6 folding prop
elite - 2200 mah 3c lipo pack

32 amps
350 watts..

here are some pics of the new fuse.....simple, light and very strong.....1/8" balsa, glassed over with 1 oz. cloth.....this is my third BD elec fuse....last one got shot down because of radio interference.....:-(

plane is amazing to watch on launch....

bob

[Desert flier]

Thanks for that I have just been glueing sheets of paper together to start making a fuse plan. thanks for the pictures and motor info. I have been looking at this motor for the bubble dancer http://www.modelflight.com.au/eflite/eflm4025a_25_outrunner.htm what do you guys think I already have 11v 2200mah bat packs :)

[neonbutterfly]

desert flier...i suggest that you run the motor, battery, prop combo, BD on motor calc.....that will give you a range of options for the prop....and what your rate of climb will be etc.....

as far as the fuse plans...i downloaded the BD wood fuse off of the charles river website and then modified it to fit the axi......used the internal mounting blocks that mark recommends......the wing center section bolts into these.....and the boom and V mount........

Pete...great looking BD.....and congrats on the build....

Bob,

Thanks for that! Bubble Dancer was a fair amount of work. About 2 hours of figuring out how to do things to every 1 hour of building time. Now I know how a composite spar goes together! I can hardly believe she's built and flying. Very satisfying! Some credit has to go to a few of my club buddies for hints and tips at certain key steps which really had me puzzled.
If I were ever to build another one it would go much quicker.

Pete
