Prospective first time builder here. Looking at the Hevle Classic (two seat fly baby) wood version as a project for my son and I. Anybody building a wood one? Are the plans complete enough for a first time builder? Anybody have a flying one near Ohio?

Thanks in advance,

Dean Courtney

As far as I am aware, there is only one flying Hevle Classic...the original, which was sold to Rotec in Australia a few years back.  I've heard of several under construction, but haven't heard of any completions.

The plans for the Hevle are basically a detailed fuselage drawing that shows the difference between the stock Fly Baby fuselage and the two-seater Classic.  The standard Fly Baby plans are used to guide construction...the Hevle plans don't include wings, tail, landing gear, etc.  If you're an EAA member, you can access the original construction series on building the Fly Baby, starting with the December 1962 edition of Sport Aviation.  This series was the basis for the plans.

Like most plans of the era (early '60s), the Fly Baby plans are lacking in engine installation details (only nine pages).  If you decide to use a modern, new-production engine like a Rotec, it's likely the company will be able to give much more help.

Ron,

I read your write-up on flying the Hevle Classic.  It sounded like you thought that the Hevle performed well and was a good tandem solution for the Fly Baby.  Have you heard anything about it's performance or flight characteristics since then that would make you change your mind?

Thanks,

 -Scott

No...from what I hear the Rotec folks (who bought the plane and shipped it to Oz) are having a blast with it.  Flight characteristics were pretty much standard Fly Baby.  When I flew from the front pit, I couldn't even tell it was a two-seater.

For those interested in my write-up, you can find it on my Fly Baby page .

Figured it would be a good flyer. Just wondering about enough info in the plans to keep a first timer from getting lost. Guess I'll find out. Speaking of plans, have heard horror stories on getting a set of orginal Fly Baby plans these days. Any thoughs??

There was a set of plans on Barnstormers a couple of weeks ago but it was gone last time a looked.  Not sure about legality or quality of second had plans but I'm sure you could find them.  If you haven't joined the Fly Baby yahoo group you should.  If you ask there someone may have a set of "un-used" plans.

The plans process is a horror.  It's in good faith, no one's TRYING to rip anybody off, but the fact is that many folks have waited six months or more to get their plans. Ordering plans involves two people, and there's a lot of finger pointing as to whose fault it is that plans are slow getting delivered.   I've tried to buy the rights myself, I've tried to buy multiple sets and do resales, to no avail.

Sigh.

As far as used plans, they are perfectly legal, as long as a plane hasn't been completed from them.  Ideally, the plans should be dated June 1971 or later...no major updates or changes since that date.   You can find a document listing the changes for the plans here .

Ron is the go to guy for the Fly Baby!  As Ron might remember, I'm one of the folks who waited a long time for a set of Fly Baby plans.  I've got the Hevle drawings, and they are a very basic fuselage drawing.  If you want to build a "bone stock" Hevle, if there is such a thing, you should not have any problems it will be easy if you've scratch built a model airplane or two.

One side note.  I recently compared my new plans to a set about two years old.  We noticed that the cover picture is different, and the quality of the copy is much better on the newer plans.  The picture page was nearly useless in the older document.  Notice I said "page" because it is just pictures of completed Fly Babies, the entire plan is drawings, no pictures (remember it is a 1962 document.)

I had printed the entire series of articles before I received my plans.  My opinion on them is, yes you can build a Fly Baby from them, but I'd consider them the "Cliff Notes" version of the plans, there is more information in the full planset.  Some of the drawings are reduced to as little as 25% of the original size, and things like the optional wing wire attachment drawings (used by the Hevles) are not in the magazine.

Last, spend a lot of time on Ron's site, it is packed with info, and some downloads too that will help you build the airplane.  Thanks again Ron!

Thanks all! I will start my plans ordering "adventure" and get the Hevle drawings on the way. Sure hope to have them by the time the snow flys here. Was planning to spend the winter cutting and gluing with my son. Last question. Were there any upgrades to the wing structure to accomadate the 2 place?

Cheers,

DC

Dean,

If you read Ron's article  that he linked to above it describes the structural differences in the Hevle vs original Fly Baby. 

As for getting started on the wings without the plans, between the EAA Sport Aviation articles (in the members only section) and information on Ron's Fly Baby website  I think that you could get started.  I'm planning on attempting a couple of ribs from lumberyard wood over the next month or two to see what's really involved with it.

Good luck and post some pics of your progress.

-Scott

Fuselage longerons and wing spars upped to 1 inch (from 3/4"), flying wires increased from 1/8" to 3/16".  Gotta be a tad careful on the bigger wing spars to ensure it fits the fuselage.  I don't know if the slots for the wing spares on the fuselage are the same distance apart as on the stock Fly Baby (I think they are), and if so, you'll need to shorten the compression ribs slightly and change the profile of the wing ribs themselves.

Dean,

I have all three drawings from the Hevle's and their DVD.  My recommendation is just buy the small drawing, the full size ones don't have any additional information, and you aren't going to lay the drawing on the table like a model.  I also recommend the DVD, they do a good job of talking about what changes they made to accommodate the ~600 lb increase in gross weight.

Enjoy the experience, and the "trip back in time" of Pete's plans, it is a great airplane.

Jim

I was fortunate enough to get about an hour with Eric Hevle at thier shop south of Bakersfield. The plane was a phenominal joy to fly, doing everyhting I asked it to do, when I asked it to do it. happy

The round engine made the experience that much cooler.

 Another consideration might be the LoCamp by Aerolab (www.aerolab.it).  It is a kit so it’s more assembly than part fabrication and critical welding and riveting is done at the factory.   It also can sport the round engine. 
biggrin

In full disclosure, I am a dealer and have one under assembly.

Hi Dean,

I have flown the Rotec powered Hevle Classic and it inspired me to build my recently completed Spacewalker 2 using the 150 hp 9-cylinder Rotec Radial.  It was featured a few months back on the EAA online mag.

The Hevle Classic with the 110 hp Rotec flies nicely, but I gave Paul from Rotec the chance to fly my Spacewalker, and he was amazed at how much more responsive the SW2 was compared to his Hevle.  If yo want any more info feel free to contact me or Paul at Rotec.  If you are set on building a Hevle, then Harry Fenton in Illinois may be of assistance.

Cheers


Martin
