Not sure I would use Elmers as any high humidity will cause it to loosen.
Not a bad write up on how to cover with tissue don`t agree with some a very good basic covering tutorial.

I did a Guillows F6F Hellcat last year with Elmers, it's still tight as a drum. My home is extremely humid in Summer, we have no AC. I did seal it with a light coat of spray paint, which probably helps, and I'll do the same for this one.

Just hit a bump-my rx/actuator/esc brick is no good. One servo does not work reliably, just sits there whining. The other works fantastic, as does the esc and motor. I've had more micro servos fail than work, to be honest, but I've had nothing but good stuff from Buzzard. I've emailed them, we'll see. I'd be ok if they just sent me a micro servo to use on the extra channel. Meanwhile, I dug a relic from my junkpile: a micro ecs/rx/dual servo board from some ancient coax eflite helicopter. THAT works, including both servos. It also has two motor outputs that are presumably pre-configured for differential thrust given the nature of a coax heli, so maybe a micro twin is in order?
Good news: As expected, Buzzard replaced the faulty part without charge or hassle. In the meantime, I bought a similar one from Amazon, it's actually identical except the servo motors are slightly longer. Also, the amazon one does NOT include a motor/prop, an option to change protocol, nor is a motor connector soldered on the board. The one from Buzzard includes all this and more, so it's still the better value, IMO. I finally finished framing and shaping the nose and attached the wing. I added an upper spar of 1.5mm fiberglass rod to stiffen things up, since she was never meant to carry such weight! About 33 grams as she sits with battery, 75 squares of wing. She may not be a floater, but I expect a good flyer. I found that MIG wire makes handy pushrod stock, a perfect fit in the medium servo hole.
It's been a minute, but I finally have some time to get the covering on. I found that a small box is helpful, except that it attracts unwanted assistants. Covering the fuse and stabs barely added 1g! I am using the original tissue, it has to be extra light for the age.

I like it! I did quite a few 1s builds such as what U R doing and got lazy and copied Horrizon using velcro on the bottom. After a while the the velcro wears out and the bat hangs down changing the cg whith each swing.
I have a zip tie as a slip latch on my Night Vapor for this exact reason.
Wrapped and painted, 37 grams with battery. I cracked up the celluloid for the windscreen so I'm going to have to improvise now. Maybe some cling wrap? Packing tape? I dunno. The MIG wire makes nice pushrods, I used the rubber insulator stripped from a junk motor wire to join the business ends on after assembly. I don't have any shrink tube that small, but the wire fits snug in this insulator so I can adjust then dab CA to lock it. Control horns from a spent gift card, hacked freehand to "that looks about right" specifications with an exact-o knife. Still some detail work to go and the floats.

Good idea. Didn't take long to find a plastic egg carton with plenty of flat space!

That's a lot of window material! Next time I see someone buying danish at the store I will ask if they are building 1/4 scale...You're missing the best one - the long flat cheese danish! Of course you have to empty the box first.
