View Full Version : Next build - Allegro-Lite vs. Genie (LT/S)

Dec 20, 2004, 04:59 PM
I am definitely a builder at heart. I like building during the winter almost as much as I like flying during the warm seasons. I am not a great builder (yet) although I am probably at least as good a builder as a flyer (intermediate). My wallet is not fat either, so I usually can spring for one kit a year. This year may be limited to buying a radio so I can play with my Falcon 880. But if it is not so limited, I am really jonesing to up my skills and build a next "level" kind of plane.

I am thinking of building a Genie or Genie LT/S. But I have also been thinking about building an Allegro-Lite or Bubble Dancer. Both will require an investment in basic tools to get started that will last me a lifetime of modeling beyond the first plane. Both will also require an investment in raw materials that do not stand for many screwups before it is wasted. Both will also require attention to detail that I have never seen before, but I welcome this challenge.

So far as I can tell both planes are great fliers with very different approaches to flying. The Genie is big, somewhat heavy but apparently flies very well. The Bubble Dancer is a polar opposite and without a doubt, even at 2x minimum weight flies well. The Genie will teach me skills in foam core prep and vacuum bagging. The BD will teach building light, epoxy skills and working with CF and Kevlar.

Anyway in typing this I have just figured out that there is probably no one who has build and flown both planes on this forum. There are no easy answers to which plane should be built first - it probably all comes down to my own preference for learning composite molding techniques now or later. If you have built either plane I'd certainly appreciate your thoughts. I think each plane will probably end up costing $600 once all the tools and one time expenses are factored in (epoxy, vac. bagging setup).

Good work on most of the background that you've done up to this point.

I've built Harley's Jouster 2 and I ordered a full kit for the Allegro Lite, haven't built it yet. I can see you spending the $600 to get a GENIE / LT/S in the air but I'm not so sure you will need to spend that much putting an AL together (if you are being conservative).

I'm not going to try to convince you to build either but I can tell you that I really enjoyed building AND flying the J2.

It sounds like you'll probably end up building both I guess you just have to figure out which one gets built first.

Which way do your flying preferences lean currently, full-house or RES?

Looks like you have a good awareness of your current building skills! These two gliders are very very different in a lot of ways. Allegro=2m Genie builds to about 3.1m. Have you considered the physical space required to build them? I'm in the Allegro yahoo group and I have a set of Bubble Dancer plans that I have looked over and looked over and looked at some more.LOL. I have also build a couple of Harley's designs from plans for the slope. My advice would be to build the Allegro because there is a bunch of support online from other builders, it is a structure that you will be able to do in parts and if you really make a mistake you may only have to rebuild a rudder or a wing panel.
If you haven't assembled a foam core wing before, I wouldnt recommend starting with an open class design. Thats a lot of materials and its harder to "evaluate" the build quality of the wings, which could lead to a prematurely broken glider (to little epoxy or delamination from epoxy that dried before assembly). Or (and this is not really a bad thing on a big glider) you will get more than enough epoxy and end up with a bit of a "sled" that will leave you with a lower performance open class glider.

thats all of course IMHO

Great responses guys, and I am more than impressed by the thoughfulness of your replies. I appreciate it.

Kevin, my preferences lean to RES right now but I have not successfully transitioned to full-house flying. I have a RE trainer and this year flew a 3M Marauder (60 oz. mostly floater) RES in a couple of contests. I was hoping the Genie would be my first full house after learning to fly my Falcon 880 properly. As for the cost, I am figuring $600 for the BD based on my need to buy a decent sized container of West epoxy, plus I think I saw a post by ASK totaling up his cost for a BD at what seemed at the time like a steep price. For some reason I thought it was >$500.

Greg, regarding the space requirements in the Spring I built a 3M glider in my basement with a three piece wing. My building table is about 5 feet of workable space plus plenty of overhang. Honestly I thought that would be sufficient for either plane!

Right now I am leaning toward the Bubble Dancer although the requirements for the different types of balsa, accuracy in measurement is a little scary. Greg's points about building (and screwing up in smaller pieces) carries a lot of weight, no pun intended. The allegro-lite group, which I have been a member of for a few years now off an on, has been very helpful in creating a comfort level for building the plane. Then again, Harley M. has been super responsive via email as well! I guess I cannot go wrong with either choice.

I've only built the allegro so I can only speak to that, but I can tell you that it was a very fruitfull learning experience. I had some experience with balsa building so I was more willing to give it a try. I was also torn between the bubble dancer and the genie. I also considered buying an Ava , but I learned so much building the allegro that it seemed a shame not to use it building the bubble dancer. The Genie looks good too and the online instructions look very thorough though a little hard to follow. The allegto and bubble dancer are soooo elegant in their desgn approach and working out of detail that i would recommend building them even if you never flew them though that would be a waste. The allegro , as I'm sure you've read , is a wonderfull flying machine, with no faults that i can find.
Good luck with whatever you choose and keep us up to date

Hello Fprint,

I have built a Bubble Dancer, and just finished 1 outer panel on an Allegro (tip and mid). I have not built a Genie, but flew with a pilot at the 98 nats that was flying one. He was doing great with it, and I think Harley is an awesome guy. I have put his RDS system on a 60 inch electric Wizard (from DJ Aerotech fame), and like it a lot.

Based on what you are saying are some of your constraints, I’d recommend building an Allegro. A lot of folks will tell you it is as much work to build an Allegro as a BD, and that is partially true. Both planes have the same amount of “setup” steps, where you mix your epoxy, set your pieces, and then let cure, but the Allegro is less work. If only because it has less surface area to shape and finish, less spar length to wrap, and the tail is solid wood pieces rather than built up. The Allegro is also smaller, and will require less building space.

The other thing that I feel the Allegro fits you well, is the cost. I figure I will have about $100 into my Allegro and it cost me about $200 to build the BD. I’m not sure what kind of special tools you will need to build an Allegro that you don’t already have. It will require some glass plates to build on, but you can pick those up pretty cheap (I think mine were $20). You can make nice weight bags (for doing the LE sheeting) out of some sand and ziplock bags. I use the EZ Lam 60 minute laminating epoxy, and you can get a small set of these for under $20. I do have a digital gram scale, so that has been handy for measuring the epoxy ratios and checking my progress as I build. I would not worry too much about the weights, as I figure a heavy Allegro or BD has got to be better than no Allegro or BD.

I’m saving quite a bit of $$ my Allegro and BD projects by building my own pod and elevator V mount. I built the optional aluminum V mount for the BD and will be doing the same for the Allegro. Building my own pod and mount saved me about $100. A guy was selling odds and ends of 1.9 ounce Kevlar cloth, and I built my pod using the “lost foam” method, but you could also build the optional balsa pod.

Whatever you choose to build, my recommendation is to just “do it”, and have fun building something.

Unless you want to do all the specialized bagging and junk which keeps the Genie an interesting footnote, go with the Allegro or Bubble Dancer. I am not sure where to get the composite parts for those either but I suppose you have figured that out. Once you have those parts, the AL or BD require nothing more than paying attention to detail as Dr. Drela shows in his 'plans'. Building them is pretty straight forward once you've studied and understood the docs. Both require no special skills or more importantly equipment.

Building a Genie, which would be my preference, requires far more time and effort in vacuum bagging and such. If someone made the cores, bagged and ready to use, I'd build a Genie. But all the bagging stuff, without a mentor, IMO is just a lot of money waiting to be thown away. Sure. There are people who have done it alone... but look at the results? How many Genies not built by Harley are flying? Bet you can use your hands and a few toes to count them. Whereas AFAIK, Dr. Drela has built those he flys and thats it. Any others were done by just plain folk.

Allegro-Lite it is, then. I need a 2M plane in my stable anyway. I have downloaded all the plans and now need to peruse the various websites to gather the hints that make building this plane a little easier. I plan to buy a V-mount, pod and boom, at least for now until I get the urge to dabble in a lost foam fuselage. Thanks all!

Just remember that to build the AL correctly requires attention to detail. If a piece is not cut right, toss it and try again. Especially the shear webbing. Everything needs to fit really well to make the wing reach it's strength potential. I speak only of what I have read, not from experience. But I have studied the AL and considered building one. But I have too many projects already! :D


Best wishes,
There is a lot of info out there. Just mine it. :D

Glad to hear about the decision, I honestly didn't think you could go wrong with either.

I'm still betting that you'll be building a GENIE at some point (or at least something similar, SUPRA perhaps). A couple of points were made in the thread about the seeming difficulty a person might have bagging a wing. If you have no one in your area who scratch builds bagged wings, Phil Barnes DVD is an EXCELLENT investment. He essentially provides a step-by-step video of the actual foam wing cutting / bagging process as well as telling you his consumable / material vendors.

Keep us up to date with the AL build,

Sorry, I have to disagree. I put together a bagging system and did my first layup on my own, with far less information than is available in the Genie files. I did have someone to talk to in advance, but that's no different than the help that's available here. My first build was far heavier than I can do now (own design model), but that's nothing surprising.

I would personally vote for the Genie over an A/Lite or BD. Just in terms of sheer useability, I personally feel (as does a fellow club member who actually built a BD) that the Drela designs are a bit limited in wind range. Yes, you can ballast them a bit, but it's a LOT of extra work to get into the appropriate weight range, only to really only see the benefit in light to medium winds at most. The Genie design is comparitively crude, but will work over a wide range of wind conditions.

Just a thought anyway...seems like you've already made your decision. Again, if you already have a plane for heavy air, then by all means, build a BD/A-lite. Otherwise, build a model that will be durable and useful over a wider range of conditions. I personally fly a heavy F3B model in all conditions, and only long for something like a BD on maybe 1 or 2 weekends per year.

I own two BD type sailplanes (one composite and one hybrid) and in my experience they are terrific performing sailplanes. We see an annual wind speed average of about 13 mph so anything 15 mph or less is considered a bonus. These airplanes will take a lot of ballast which allow it to penetrate better without sacrificing handling. They indicate lift very well and are viceless. I just wish that there was someone who kitted the BD so as to make the build easier since it has turned me into a big fan based on experience with my overweight birds.

There is also a Genie in my club and while i've not flown the plane, it seems to be another great flyer; either way is a win situation.

rdwoebke
Dec 21, 2004, 07:40 PM
I have flown my Bubble Dancer in a bit of wind, and I think it handles it well. I have flown in up to 15 mph wind with it, and have not yet started experementing with ballast. To me, the BD flies a lot like the Paragon, except it has way better speed range (for obvious reasons). I usually ballast the Paragon with 8 ounces when the wind is 8-12 mph and then go with 12 ounces or 1 pound when it is over 12 mph.

The thing I don't like about the BD in the wind is the grip when you are launching it. The fuse is very small, and I have not yet mastered the "grip it by the nose" launching technique. I prefer launching the Paragon in wind due to it's large fuselage to grip onto.

Granted, the Genie would handle wind much better, especialy the 20+ mph stuff.

fprintf,

Here's a question: What do you think you would find more enjoyable this winter, Building a BD or AL and putting your current balsa building skills to the test to build one of the most "advanced" balsa rib style planes, or learning all new skills and discovering how to do vacuum bagged composite wings?

In essence, one plane will let you "test and improve" on all the building experiance you already have, while the other will challenge you to learn all new ways of building?

Both are great planes in their own ways so I don't think it is the "plane performance" that is an issue in your decision, more likely which will afford you the most enjoyable building experiance. :D

I thought the nose launch might be a problem, but I got used to it really quickly on the allegro lite which has a much shorter nose than the BD. Really not bad though I a'm not using a winch, just a stout bungee.

The #1 tool to have, the one I wished we had bought before my son and I built our first Bubble Dancer?
A .1 or .01 digital gram scale.We used a scale that rounded to 2 grams. Cheap, but not enough resolution.

So if you build a BD or AL, spend a few bucks and get a good, accurate scale. We have an Ohaus triple beam balance now, but still will get a digital gram scale in .01 before we build our second BD and our first AL.

These are such great flying planes. I trust you've seen Thomas Wang's photos of his AL build by now, here in RC Groups? Excellent to guide you along.

Agreed, the decimal reading gram scale is handy. I like it for getting the epoxy ratios just right, and it is handy because the plans have an estimate for how much epoxy goes into each pannel, and you can use this to roughly gauge how much epoxy to mix up.

I'm trying to get used to the nose hold over hand throw. I think it might be easier on the Allegro, because the model is smaller and there is less wing to worry about bonking you on the head. In the spring, when I finish my Allegro I should know for sure. :) :D

Currently I'm building a "big" Genie. It's been a great experience but I just haven't had that much time to work on it until recently.

One other possible contender would be the Supra (another excellend Drela design). This is going to be my next plane on the table. Hopefully by then there will be a Drela spec. pod and boom being offered for it. I can make the pod myself...but I don't like the idea of rolling my own boom!

I used a piece of aluminum right angle stock for straight edge and for a long sanding block. One of the new concepts ( to me) that I really learned from was the tangent sanding setup for getting the correct airfoil shape. Didn't have a band saw or belt sander, but I do have jewelers saws and a grinder as well as flexable shaft with cutoff wheels and 1/2 inch sanding drums. (

Thanks for all the hints! I must have known I would be starting such a project because I purchased a 200 gram .1g resolution pocket scale a few weeks ago for measuring epoxy. http://www.saveonscales.com/120z.html. It is a bit small for measuring big parts as you need to balance the part carefully on it and then sneak a peek under the part to view the display. I am now tempted to spend the $70 and get the larger tabletop version at http://www.saveonscales.com/i500.html.

The other thing I just bought on Saturday from Harbor Freight was a digital caliper - on sale for $15 at http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=47257. I was tempted to buy two to split the shipping and handling (and qualify for a coupon) but ended up getting an airbrush to hook to my compressor instead.

Oh, one other thing on the scales. I visited http://www.digitalscale.com/scalemagazine.htm and looked at quite a few of the reviews before purchasing mine. They currently have reviews on some inexpensive .01g resolution scales, although for my building skills I think .1g is quite sufficient (moving around the scale while it is measuring causes .1g fluctuations due to the air currents).

Plus he was offering it only as a kit, since I have my own CNC Foam cutter I would rather do the wings myself, althrough from many reports his cores are excellent.

There has to be a mold out there somewhere with people making the pod and the boom...there are a couple of true Supras in existance so they're getting the parts from somewhere!

Just make sure the mix ratio quoted in your epoxy instructions is designed to be measured by weight. Not all are quoted that way. In fact I have seen some that warn the common mix ratio is by volume! If done by weight, the oft state ratio needs to be ignored and different (and less convenient) ratio used. Make sure you use the right one.

Dec 22, 2004, 12:24 PM

All of the laminating epoxies I've used (West Systems, ProSet, Resin Systems.) offer ratios by weight. I never use the pumps for proportion.

FWIW, Klasskote epoxy paint warns against using weight ratios since their pigments have different mixes and densities.

Mark machined his own boom mandrel for the Supra.

I don't know the story on the pod mold, but a discussion took place on Allegro-Lite Yahoo group about Rick Walba offering a shorter than spec boom. Including feedback from Mark, the conclusion was to gratefully use the shorter boom from Rick (when it is available), and to make a longer pod.

That said, Barry Kennedy has a Supra molded craft in the works. He says they are working on an "as plan specified" (or as close as possible) pod and boom. For Allegro-Lite members he said he would offer the pod and boom separately. Since they have to wait for after hours time with the machinists making the mold, it could be awhile before we see it.

To save time one could use Les' offering, or even use an AVA pod and boom. It's about the same length from LE to boom tip, and you just accept whatever pod/wing boundary layer interference the pylon eliminates.

About a year ago, I bought the small scale pictured. It worked fine until recently when the batteries got low. When I replaced the batteries, the scale refused to re-calibrate. It's useless now. The error message that it displays implies that it was damaged. It wasn't.

I just wish that there was someone who kitted the BD

Evan,

Ava from Kennedy Composites is a mfg'd BD.
http://www.kennedycomposites.com/ava.html
I have one. Excellent build quality.

A similar prefab is the Topaz from Hobby Club
http://www.hobbyclub.com/HC-3mRES.htm

I think the Ava (BD) can handle wind with ease. Admitedly, not as good as the heavier molded planes. There are 3 Ava's in my club. With my Ava, learning use of ballast is key. I have ballast sets of 9 and 19 oz. for varying wing conditions. My plane is 40 oz without ballast. I've flown several days of steady 10 mph winds with no ballast. Just can't go as far downwind before bailing out with no ballast. Pilot's flying style might dictate if he likes this plane or not.
rdwoebke,

yes my Ava, like your BD, is sometimes difficult to hold the fuse in the wind. I use the "grip it by the nose" technique. I am impressed you built your own BD and especially for under $200. I'm guessing $80 of that would probably be for pre-fab spar caps alone. Wow.
fprintf,

The only trouble I have with building Drela planes (finishing up an Aegea 130" plane this week), is the lack of instructions and tips stored in a single place. Most details are covered in the plans, but not all. Then these other details dribble out over the following few months in several email forums. I subscribe to several of them, just to keep up with such details.

I am impressed by your desire to build and by your analysis of your own limits. I build more than most I know, and do mostly vac. bagging. If you go that route someday, the Phil Barnes DVD is the way to go. I have bagged for several years, and didn't learn too much new. But there were a lot of small things I did learn that help me improve my techniques.

The largest cost is the vac equip. A 1 1/2 qt set of epoxy is not that expensive. You might also want to build/buy a foam cutter, if your cheap, like me.

yes, all the techniques are different, but not that difficult. I suggest building a few small parts first to work out your technique before moving on to a whole plane. Build a few stabs or rudders first. You don't even have to put carbon in them. Just build for the learning & throw them away. Wasting the carbon required for a messed up 3-meter wing is a lot of $$.

I am encouraged by your enthusiasm and discernment.

Go for it. The satisfaction of having your own built plane is worth it.

rdwoebke
Dec 22, 2004, 06:49 PM
JonStone, I'm impressed that you built an Agea! I have only seen 2 flying, and both were Phil Barnes Agea wings. One was on a Mantis fuse, and the other was on a AVA fuse. You should post a picture.

Per your $ comments, I figure my investment breaks down as follows:

$90.00 - Carbon spar materials, joiner materials, Kevlar wrap, and carbon/Kevlar cloth for the pod. A guy on RCSE was selling Kevlar odds/ends for $20.00, and I could make at least 5 pods out of that.
$32.00 - rib kit
$28.00 - Boom from tailbooms.com
$2.00 - Aluminum for the V mount
$15.00 - balsa and light plywood
$20.00 - covering
$3.00 - epoxy and carbosil
$3.00 – misc sand paper, razor blades, brushes, etc.
$6.00 – pushrods and housing

For the Allegro, the Carbon is less than $50.00, the rib kit is $12, and the boom is $18. I figure I'll put less than $10.00 into balsa on the Allegro, and probably just need the equivalent of 1 roll of covering.

Granted, in these price breakdown I am not including things that I did not fully use or can re-use, such as glass plates, sand bags, epoxy, etc.

A picture of my Allegro progress to date. I also have the left tip done, and am getting ready to lay up the left mid.

evan,

I have flown several and owned one RES planes with bagged wings. I didn't like the way any of them handled. Not responsive enough in rudder for my tastes. Now the Ava (B.D.) is another thing entirely. Wow. Turn the rudder, and the plane responds immediately.


rdwoebke,

I don't want to hijack this thread. I'll start another thread on my Aegea build. Getting the joiner boxes correct was the most difficult part. Your wingtip looks great.

JonStone, I'm impressed that you built an Agea! I have only seen 2 flying, and both were Phil Barnes Agea wings. One was on a Mantis fuse, and the other was on a AVA fuse. You should post a picture.


Warren built one recently that he documented here:

Not the same pod, but close enough for jazz. If I weren't up to my ears in molded photo plane, I'd work on one myself. Actually, even that's a lie...I think I'll be doing a CO9 first.

So, fprintf, what are you doing now? I'm sort of facing the same question you were, only with me it's a LT/1 (small Genie) or Aegena. Have you started building the Allegro?

Hi Gary, I decided I am going to build the Allegro-Lite. However I have another diversion to get my fingers warmed up for that event - I am building a Laser Arts Jester at http://www.rcgroups.com/forums/showthread.php?t=340185
