I have her to the point that I could do a maiden flight and I like how she flies, although she takes more attention than most of my planes. No dihedral, KFM4 airfoil, she's a point and shoot plane. Gonna be very acrobatic, way more than I can do, but maybe i can learn - assuming I don't trash her!

More work done, got a couple nice flights today with the new landing gear.

I finally got around to actually building this one, having gotten the parts laser cut months ago. She went together well, (Loved the straight lines and tab/slots that fit ) But I discovered several additional parts were needed and others needed changing so she's not quite a one sheeter (yet) But I have flown her and she's fast for a 2s BW plane. I was afraid I'd have adverse yaw with the aileron servo setup, but it doesn't seem like it will be a problem.

OSM Mr. Mulligan - OneSheeter#11 (2 min 16 sec)

I finished the floats and got some video of the bird back on the pond, as I mentioned before, she's a hoot to fly! I haven't quite got the greased in landings right though. (seems to be an ongoing problem with me...) After a full session, I splashed her one too many times and may have toasted one of the esc's, and HK is out of stock, so I guess she will sit in dry dock for a bit! Enjoy the vid:

SuperTwin (2 min 4 sec)

got in a first flight off water with the Trainer1.5 cobbled into a sea plane this morning. I figured I should come up with a name more descriptive than the long description in the first sentence, so I like SuperTwin, with the T giving recognition of it's heritage in the Trainer1 concept, since the wing and tail empennage is salvaged from my Trainer 1.5. Anyway, made tip floats from pink foam (2") and dowels, secured to wing with the pvc fuel line trick (works pretty well). I have to say flying off water with a twin is a serious hoot! I can power her out into the pond, stop, then go full rudder (left stick where the motor differential is located right now actual rudder is on rt stick) and give a touch of throttle and she will pivot on the opposite tip float. first takeoff was uneventful. she got on step quickly and skimmed for a few feet before lifting off. tip floats kept her nicely level, but on step they were clear of the water, so no drag or splash. Landings, on the other hand, haven't been as smooth. I seem to come in too hot, and either have to do a skim and go around, or bring her in, pull up and plop her in. Practice..... Now I need to figure out how to do the water plane with operable bomb bay door. Maybe I'll just pull the tape off and see how she goes... No pics yet, but if not too windy tomorrow, I'll try for pics and vids.

I finally got all the trim done on the Seabee, which is now officially an OSS, for 24x48" sheet (couldn't fit her onto the ds foam 20x30). And, I got busy at the last minute to build a plane for a candy drop exercise at a friend's Vacation Bible School. Unfortunately the candy drop got scrubbed due to weather and time, but I went ahead and finished the plane anyway. I recycled a Trainer 1.5 (56" span) that I'd built years ago. Hadn't flown it in ages, but it took up lots of hanger room, hmmm, maybe make a full fuse with bomb bay. While I'm at it why not a twin. After cannibalizing motors and esc's from a coupe of other planes, recycling the servos and wires from the original and adding a new tgy 2.4 8 ch rx she finally appeared. Not sure what to call her yet, but I added a step just in case i wanted to do water work with her. (she's too top heavy to sit right at the moment, will need tip floats or sponsons).

I now think I've wrung out all the "issues" with the Seabee. I'd first shortened the float arms, after noticing that both tips were dragging in the water on straight taxiing, and figured that was a prime cause for them being sucked under on speed up. While that seemed to help, I still had a lot of water getting into the prop, and she wanted to rock side to side. I finally added splash rails to the lower edge of the fuse, and reshaping the floats to sharpen the aft "release" tips, she now skims the water nice as can be. I had noticed that essentially all the pics of the full size planes had the splash railsl, so figured they might help....

I'm pleasantly surprised at how well she gets up on step. All my other water planes (three of them) need lots of up elevator to keep the nose up, but with the Seabee, I just increase throttle, and she comes up and skims along, lifts off with just a blip of up elevator. fun to fly on still water!

SeaBee Success! (2 min 57 sec)

The latest bit of insanity from Armada is what may become OneSheeter#10, the OSS, based on the Republic SeaBee, a quirky bit of aviation history. Here's the build thread: https://www.rcgroups.com/forums/show....php?t=1625525 And here are a couple of pictures. hopefully soon I'll try her off the pond and perhaps even have some video.

I just realized I hadn't posted any pictures of the latest onesheet planes here, so folk have to actually go to the build threads to see what they look like. How rude of me!

had to carve some pilots out of pink foam chunks for these open cockpit planes....

Lousy weather to fly this week, so I thought it time to pretty up the onesheeters with logos and some color. Yellow and red/orange are Krylon fluorescent spray paint dry sprayed on. The Blue is Walmart Colorplace cheap "buck a can" spray also dusted on. Gotta watch it doesn't eat the foam, although I found that "tempering the foam first with a heat gun til the surface just begins to "shine" helps resist melting the foam.

After confirming (over and over again!) the the original OSW design wasn't stable, I redid it and came up with version two, now posted on the OSW thread. She flys much nicer, very stable and yet fast enough for me. (I got one 68mph pass using RCspeedo on my android phone). Best of all she uses up more of the DS foam sheet. Love to maximize sheet usage!

Next up is a One Sheet Floater. (no thread yet) This one came out of a thread on the modeling science forum where a guy wanted a plane that will fly at a walking pace (he targeted 3mph) yet be a decent trainer. I know that my BluBaby 42 will get really close to that, but hey, why not try a high wing floater from a single sheet. It's still in V1 and I discovered yesterday on maiden that cg/balance point is way aft of where it needs to be for stable flight. That will require some changes as the battery "wants" to be right behind the motor now. But that's just more tinkering fun.

There's also a OSN17 (OneSheetNieuport17) on the build table which will be an even more "interesting" development......

A couple guys have suggested I should include these in my blog, so I'm adding the latest bit of foamie madness from Armada: One Sheet planes. This all started over a year ago, when one of the RCG members proposed a challenge to design and build planes from a single sheet of Dollar Store Foam (20" x 30"). The challenge proposed classes for speed, heavy lift, duration, etc. Unfortunately it never really got going, but the wife and I happened to be on vacation in Texas when I first read it, and during the extended travel times driving around TX and on way home, I figured out how to make the One Sheet Glider (OSG) entirely out of a single sheet. Worked up the design in Sketchup, printed tiled plans and put one together. She flew quite nicely with original KFM5a wing in light air, and thermalled pretty well. Further tinkering resulted in a Version2 with KFM3 wing and it was even better. Build thread is here: https://www.rcgroups.com/forums/show...&highlight=osg

Having done the OSG using the entire sheet, with only tiny slivers of scraps, I was hooked on the idea of "how many plane types could be made using up an entire sheet?" That led eventually to the One Sheet Bipe (OSB). Build thread here: https://www.rcgroups.com/forums/show....php?t=1368918 . This one doesn't use the sheet quite as efficiently, the scraps are a bit larger, but It's still pretty efficient use of the space available. It's gone through two versions, and I have to say the...Continue Reading

I found this jpg file with proportions for floats for float planes. Unfortunately I've lost the source, so can't give proper attribution, so will apologize in advance. But the guidelines seem self explanatory and work well, in my limited experience.

In last post, I mentioned the latest version of rolled/folded fuse, which is now dubbed QuickSilver (based on it's being painted with Walmart Aluminum spray paint) She has her own thread, ( https://www.rcgroups.com/forums/show....php?t=1329784 ) as shortly after I finished adding gear, I lost her in a bean field for a month and a half, and how she survived was sort of interesting. here's pics of the finished plane. She is a very nice flyer with a towerpro bm2410-08 and 9x7.5 sf prop on 3s 1k or 1500 mah packs. Not unlimited vertical but a very decent climb(60deg+), rolls pretty scale-like. Fuse is rolled readiboard while the wing is kfm3 from PBlll.

Haven't posted to the blog in ages, but thought i'd add to the folded fuse development with some pictures of recent planes. All these planes use some variation of the folded or rolled fuselage technique. The Mike and 40" span racer were rolled over mandrel in a gpw bendfoam fixture, while the rest were folded at the "razorback" aft fuse top, and in most cases rolled mid height to add some curvature to the cross section.

Here are several pictures of the 42" BluBaby I built over a year ago and still fly it frequently. Started with a enhanced UC wing with fwd 40% of wing doubled on bottom (hence the kfc - Kline Fogelman camber - designation), skewers on Leading and trailing edge (Skewer wetted then laid in groove in edge, Gorilla glue applied to groove previously, then the whole mess over wrapped with packing tape to hold the glue while it foams and forms a nice rounded Leading edge. Nice strong, though flexible wing.

Also made a removeable wing saddle that allows use of the KFC wing or a KFM3 wing with ailerons.

a bit of my history: I had dabbled in rc back in early 70's in the army at Ft. Hood, TX, but was balsa, glow fuel, too big an engine for the plane. no help local or online (online, what was that in '73? clothesline maybe ) never got longer than about a minute flight, finally sold it to another GI. Came home, married, raised kids worked at GM, got a retirement package in '02 and decided I wanted to try again. This time with a glider, gliders fly slow, dont' they? (well, no, not always.....) Built a Gentle Lady (balsa & monocote) and got a Futaba Skysport 4ch fm radio. Flew, crashed, flew crashed, etc. same prob, one minute flights and 2 day repairs. almost gave up again, then found a yellow bee at Harbor Freight on sale for $25. How bad can it be??? Man, that plane was fun! Slow enough and floaty enough I could work the sticks and make mistake but correct before crashing (usually, but if I did crash, she just bounced and I put her back up). Was flying one day, and got her pretty high, dawned on me I should bring her down, but she didn't have rudder/elevator, just differential motors for steering. So, while I watched helplessly, she floated away. Never found her. However, I figured I might find something like her online, and found RCG, checked out the threads, found scratch builds, lurked, found the Trainer 1 thread, built one from some scrap Owens Corning pink fanfold from a friend's new house dumpster. Flew her til I learned the sticks and some of the "ways of the...Continue Reading

Tried a second iteration of the fold/monobloc fuse in a full fuse Parkflyer Pete. I used gpw's templates for the profile Pete and traced the fuse on the folded blucor (had to make the fold, as I only have the high perf which doesn't have built in folds - make the fold along the waves not across them, I learned) I used the Bendfold fixture to make the wide line along the center of fuse in side view instead of the bottom as in the first version was pretty easy to get symmetrical. a bulkhead and the monobloc helped. GG for laminations and hot melt for butt joints to hold it all together. Used three layers of blucore for the monobloc on this one.
