Default Foiler - new funfly design

Here's a design my brother Daryl has been working on. He designed it primarily to get better knife edge performance with a funfly.

Default Foiler Fun Fly Design

Hi - I'm the designer/builder of the plane my brother posted pictures of. I'm currently in the middle East for 6 months on deployment at a "secret desert location" employed in the war against terrorism - enough said. The Foiler design got it's inspiration from the outstanding designs of Don Incoll's Wasp - one of the nicest flying planes I've ever had the pleasure to fly, and Brian Felice's Wedge design. Brian is a master of truly innovative construction - he's into geodetic construction and basically uses only enough material to get the job done. Now there's a guy who now's how to build light and strong! I borrowed some of their ideas - Brian was kind enough to share the basic dimensions of one of his Wedges - and drew up my own plans and started framing. It's got plug in wings on a 1" Gator wing tube set, 1/4 stick fuselage with 1/32" ply reinforcement up front. It started out with a S.T. .60 which was very marginal and now has a S.T. .90 - it can still use more power! The airframe is very light - around 7.5 Lbs if I remember correctly. Considering the wing is 4 5/16" thick and has just under 1000 square inches of area (this is a big plane!) this is quite light. With such a thick wing this plane is very draggy. I think the wing chord was 16" plus 4" ailerons - 20" total chord and, if I remember correctly, about 52" span. It'll hover with the .90, but not with the authority I'd like. You'll notice I use a mousse can after muffler to quiet things down - I'm sure this robs a bit of power. The rudder and ailerons are very powerful - the rudder actually too much so! Lots of exponential is a must! I only got about a half dozen flights on it before shipping out so I was still playing with setting it up. I started out with the C of G fairly far back which made it quite a handful - a bit unpleasant to fly actually. Changing to the .90 up front made it much nicer. Surprisingly I found at times it exhibited a bit of a sudden stall which really scared the hell out of me on final a few times. I'm thinking the C of G should be moved even further forward... My brother is digging me up a used Enya 1.20 4 stroke - when I get home I may have to hang that up front to check it out :^) Might as well make the nose weight look and sound good! I hope this helps. Cheers

Default Shameless Attempt To Bump Post To Front Page To Generate Discussion...

OK - I'm in the middle east on deployment and I'm bored silly - flail me for bumping my post :^) I honestly thought this design would generate a bit more discussion! Guess it's just tooo uglyyy! I thought it's kind of neat though. Cheers

P.S. Sport Flyer aka my brother Kelly - post the link to Brian Felice's website I sent you if you've still got it. Super impressive engineering and building....

Default Definitely shameless

... maybe it would generate more interest if you somehow involved Billy Hell?


Well Brian Felice's website is:
http://members.cox.net/bdfelice/

I think the link you're referring to is the one about his Wedge design. I'm also interested in what he has to say on night flying -- love to try that with the Seniorita, course I'd have to recover it with transparents first.

Cheers and give those commies, ah, err sorry, that was yesterday's enemy -- give them terrorists hell!

Wild3dfunfly, I wasn't aware I was talking #$%# about Billy Hell. I was replying to a query my brother made about the thread not generating interest and suggested that maybe he somehow involve him. BTW, this thread has nothing to do with the Spoiler, the plane in question is called the Foiler.

Hopefully this has cleared up any misunderstandings,

Regards,
Kelly

Sport Flyer I do believe that Wild 3 D was playing is all. I am sure he meant nothing bad by it.

Dream Flyer, whether he was joking or not, his post left me with the impression that he was reading impaired and ill-mannered. From my understanding of proper net-etiquette he gave no indication he was "playing".

Regards,
Kelly


Btw, what do you guys think of the construction techniques that went into the Foiler? I think Termagator had a point when he suggested Daryl should have covered it with transparents to show off his craftsmanship.

Default Sticks etc.

I agree with Daryl, it is kinda ugly, but when form follows function, and one is not a designer for Ferrari, then it usually does end up less pleasing to the eyes. I concur with Termagator, and it's not just because Termie rules, but a clear or transparent covering would have done this plane much better justice. When you have this kind of triangular design, with cross braces and even carbon fiber laminate reinforcement, ya have ta shov it off!!!!!!.
The reason I don't find it pleasing to the eyes, is mostly that constant hight fuse, which is even further visually enhanced by the covering.
Regarding the building technique, it is awesome, but is it suitable for something to be flown low, slow and close???? How well does it absord "crash landings"? or Harrier landings? Is it more cumbersome to repair? Maybe these questions are not really relevant, maybe the design should purely be seen as a study in this type of building technique.
It is fun though to design and build a home brewn design, and find out that it actually flyes quite well. I have a small profile bipe I designed and build, 36" wing span, basically two PenKnife wings, and it has so much coupling between all the control surfaces, that it is really a hoot to fly, basically there is no way this plane can be flown straight ha ha. The lucky thing is, that when you get off the throttle to "glide" it in, it really calms down and behaves decently.
Anyway, take care at your undisclosed location.

the last 2 planes I covered were built by someone else and they did a great job building them. Covered one in transparent yellow...the other in transparent red, both look really cool. sport flyer..... get your brother to build 2 more...and I'll cover one for me and one for him<GRIN>....Gator

Default Crash Worthiness

Hmmm, good question about the crash worthiness of such a design. I hope not to find out, but I personally think something built that light is fairly fragile, even with the carbon fibre reinforcement. I take great pains handling it to ensure I don't damage it during transport, assembly and dissassembly. I hate repairing and that 1/4" stick truss type construction would not be fun to try to piece back together. This is one of the reasons I do hovering manoevers up fairly high! My Wasp on the other hand is hell for leather strong. I actually dorked it straight in to the tall grass beside our strip one time when the engine flamed out (don't know why it did it - it's never happened since) with no damage! Re the fuselage - it's 12" tall at the front tapering to 7" tall back at the tail post. It's not constant height at all. I've got an Ultrasport 1000 in a box and have cut a second set of wing ribs to scratch build a second one. Maybe I'll build a set of Ultrasport 1000 type plug in wings for this thing - it would fly like a pattern plane on the Kaos derived wings and a fun fly plane on the thick set. It's sure fun to scratch build and play around with "designing your own". I find it much more statisfying than building from a kit, although I must admit, if time is not on your side smacking together a laser cut kit like a Sig Something Extra or 4 Star 60 is hard to beat! I didn't have any clear covering but had a fair amount of Ultracote lying around leftover from a bundle deal I got through the internet. There's not too many planes you could get away with putting that chrome on, so chrome it was! Damn strange looking in the air that stuff is! High visibility wing tips are a must with that stuff! Heh guys - lets keep things light and on topic. I'd hate to see RCU degenerate into what happened over at the old RCO. I found things got kind of ugly over there at the end. This has been an absolutely 1st class website so far - lets all have fun out there!! Cheers

From a secret forward operating location out in the big sandbox... :^)

Default Foiler - new funfly design

THERE WAS A SIMILAR STYLE OF MODEL OFFERED AS A PLAN IN ONE OF OUR MAGS HERE IN THE UK.I DON'T REMEBER MUCH ABOUT IT EXEPT THE VERY DEEP FUZ AND THE FACT THAT IT HAD THE ENGINE MOUNTED ON A SWIVELLING SYSTEM WHICH IN TURN WAS CONNECTED TO A VERY STRONG SERVO SET UP ON THE RADIO TO OPERATE IN CONJUCTION WITH THE RUDDER, AND I QUOTE: "TO IMPROVE TURNING,KNIFE EDGE AND AEROBATIC MANOUVERS"

JUST A THOUGHT IF ITS XTREME KNIFE EDGE YOUR AFTER.

Default Knife Edge Rudder Authority

bradders - this foiler design has so much rudder authority it's actually hard to handle. We're talking turn on a dime here which requires lots of exponential and a smooth thumb to stay ahead of. I could have gotten away with much less rudder area for sure. Cheers

Awesome looking plane.... I've admired Brian Felice's stuff for a while now... and I've often thougth of using a fuse like you did with a wasp wing.... Maybe some day....

Good luck out there... take care of yourself... We're all keepin' you guys in our prayers.

Default Thanks

Thanks for the kind words Paul. Yes, it's an interesting fuselage design. I'm thinking of maybe trying to build an Ultrasport 1000 type fuselage using the longeron and truss method. It's certainly much more labour intensive to build, maybe more fragile too insofar as handling is concerned. I guess if it's lighter and still hangs together in the air it's a success engineering wise. I just can't afford fancy fibreglass pattern planes and I find scratch building is surprisingly cheap when compared to kit costs nowadays. Like most of us, I have a big stack of kits though that I really do have to get around to building :^) Cheers

Default RE: Thanks

I designed built and published three FOILERS in 1991 the first one was the 60 size FOILER the next one was the LIL FOILER and the third one was the BIG FOILER all of these planes fly well and the plans can be had from Model Avation, MAN RCM. JOHN TANZER
