Thanks guys... I have a soldering iron, or 2, or 3, and solder, but no talent. I'm going to buy an e-flite 30 amp. It has the right conectors and I may at some point put a bigger motor on it, so I'll be all set with the esc then. . . Capt'n

I am using Polyurethane-Glue. It is foamy and the residue can be sanded down easily. Makes very strong connections. It is very cheap too. 750 gramms for about 9$.

Dont know how it is called in the USA and if it is available there.

You'll want AUW to work out the wing loading rather than the kit weight. From memory they end up with roughly the same wing loading.

The starting point is 5.5g/dm2 and 9.1 g/dm2.
Final wing load ( AUW) depends on the setup for each case.

Let's say that the setting is for minimum weight( Lipo, brushless) for both sizes, 600mm and 900mm , Mini PopWing /PopWing or Bonsai/Teksumo.

Bonsai/Mini it's much better to float?
I've flown both stock kits, and the 900mm Popwing/Teksumo feels slower, but I suspect they both fly about the same speed, it's just the larger wing seems easier to fly slow with. If you were going to be flying in a small indoor venue, then you might want the Mini just because you can probably turn it sharper if necessary. Otherwise I think they both do well as slow flying wings if you like to fly like that.

Just to clarify the "stock kits" I'm referring to are the Mini and 900mm Popwings that you get from Nitroplanes.com with the electronics included, which work quite well for slow floaty flying. You can probably build them even lighter if you figure out lighter electronics that can work, but the stock setups seem to work really well for slow flight in my opinion.

any motor/eCalc experts here?
I just mounted a D2830-11 1000KV motor & 8x4 prop on my popwing based on the motor math that I did on eCalc/propCalc. I haven't had a chance to test it yet, but I wanted to get some feedback before I did. I googled 'popwing/teksumo D2830-11' and didn't get any hits, so it doesn't seem like a popular motor/prop combo for this wing.

I'm aiming for efficiency, range & long flight time for an FPV popwing, not so much into acro&speed flying. So, this is why I chose the D2830-11 and bigger prop. Before this, I was running the popular D2826-6 2200 + TGS 6x4. It was pretty fun for LOS, but too much of a speedster/battery killer for what I'm trying to achieve now.

Can anyone please help me figure out if I made an ok choice with this combo, or if it's a thumb's down? I'd really appreciate any help/feedback...thanks

3S, but are you 100% positive about that though?
I ran that motor through eCalc with a few different prop sizes, including 8x6 and 9x6, and the only one that it seemed to like was the 8x4 (on 3S). Do you think one of those other two prop sizes would be a better choice? if so, which one, 8x6 or 9x6?

Again, I'm aiming for efficiency, so lack of speed/performance wouldn't matter as much as efficiency. However, I also don't want it to fall out of the sky or have it be a huge hassle to hand launch, so I'd need enough thrust to take care of that...

I wanted to follow up and say that I did 5mm of reflex on my 2200 mah 20c powered wing with a 2212-6 ebay motor. It flies great both slow (floater!) and fast. I like landing it on the smooth surface of the bottom with no battery or esc/receiver to hit. When I let off on the throttle, it no longer noses down. Very pleased with this wing.
