First try at second picture wouldn't load.  I'll try again.  "UP" arrow is to keep me from making my usual blunders on launch.

It needed down thrust, which eliminated a slight power stall.  I need more right thrust, which I'll put in the next time I fly it. I used a Gizmo Geezer thrust button, which means no shims.
The model is a kit by BMJR.  It is still sold, and supposed to be a good flier. It looked like a good flier today, on partial winds.

Looks really nice Dohrm.
I  wouldn't mind seeing a detail of the prop freewheeler set up.
Thanks,

I used the modified instructions included in the kit.  It does involve soldering, but that isn't that big of a deal.  I'll try to get a good close up picture of it for you.   The freewheeler works well.  However, as with all these freewheelers using snarky bits of wire for the freewheeler latch, you have to watch out when you hook it up, as it will slice you up good if it slips. 

You also have to wind the thing up correctly. [backwards].  I did not on my first attempt, and had to do it all over again.  Oops........... winding it up wrong guarantees you a close encounter of the worst kind with the snarky bits of wire.

Thanks Dohrm,
NO rush on the close ups.
ALL good advice regarding snarky bits of wire too.

I look forward to seeing the canard in flight.  Post some video!  I've always liked canards, just as something relatively unusual.

Weather permitting, I am going to fly it down at the Wintercoupe contest in Pensacola this weekend.  I'll try to get some video.  Hopefully the sun will be out.

Just finished up this one today. The design is called the Banana Fritter. I don't know how I did it, but this one came out pretty light by my standards. Just a smidge over 41grams. I seem to have built something that will actually need a DT.   Huh   Retrofitting shouldn't be too hard, I just didn't think I'd really need it, given how heavy my stuff usually comes out.

Great looking airplane!  Nice work.  Yeah, you'll need that DT-shame to waste all that effort, and watch it sail away.

Pop up stabs won't bring it down every time, and if you use a pop-off wing, it is a major problem if it comes down in a tree.  However, I have only seen one fly away with a pop off wing. All the others have come down.

Let us know how it flies.

Bargle,  That's snazzy lookin' airplane.  Yes, get a D/T on that.  You probably know that the thermal critters know when you either don't have one, or forgot to use the one you have installed.  That is certainly the case with a few I've tossed up.  Makes for some very long chases.  Caley

Very nice Bargle. What have you done at the poly breaks on the wing? It looks like you have overlapped the tissue at the join.
Happy flying.

Um, covering up a goof. I used the 'doubled ribs at the breaks' building method on it. I didn't use stiff enough ribs at the break and they distorted slightly when I shrank the tissue before joining the sections. Rather than take the ribs back out and replace them, I took the lazy approach and fitted some tapered filler pieces in the gaps, then covered over them with the strip of tissue.

Well it looks good and is no doubt stronger. i was curious because I would have trouble handling the covering at the poly breaks.

I flew the Tail Firster canard down at the Pensacola Wintercoupe contest this past weekend.  It was rainy the first day, and really windy the second.  The planes would drift almost a mile in 2 minutes. 

I flew it anyway, with short fuses on the DT.  It handled the gusty winds quite well, and seemed to glide OK. It climbed out well, except for one launch that was a mistake on my part.  I still haven't gotten full turns on it, as I only flew enough to see if it would hack some wind.  I was more worried about it being wrecked after landing, if it got tumbling around. 

If any of you are in driving distance from Pensacola, you should get down there for a contest.  It is one of the best fields in the USA, being a mile square.

It certainly gives me problems. I've considered starting a thread asking for tips about that part of covering. I seem to be at least tolerable on the other parts, but the breaks always give me trouble.

I was lucky enough to have someone tell me of an excellent way to cover poly breaks. Before that, it was a continual horror show.  An ugly horror show.
This is pretty easy, and ends up looking good.  I'll be happy to post it if you start a thread, or tell you about it right here.
No more French curves!
Once you get the hang of it, the tips will look very nice.

This may not be in strict adherence to this thread,but what the heck.

Me, three Grin!   It's one of the reasons I "prefer" models with only one break in the middle.  I was also considering building a "SATURNO" (minus holes), but time is getting too short (in more ways than one plus too many outside projects) to think of scratching one, so I will be ordering an IKARA "Pee Wee".  It's available as a kit, ARF, and RTF - I'll probably get the kit (I'm NOT Bill Gates and I prefer to build).  A few more tips on covering the wing would be helpful (I've actually FORGOTTEN a lot of "how too's").

Finished another one. This time it's my Baysik Bahks Mk. II. only real change from the first one is a relocated rear rubber peg and resultant longer upsweep at the rear of the fuselage. Something's going right for me on these. This one came in at 43.2 grams. For comparison, my Mk. 1 came in at 60 grams.
That's 2 at a reasonable weight now. I'm either building better, picking better wood,  getting lucky or all 3.   Cheesy
