got my mini guinea painted! I was so stoked to so this scheme:
and here is what turned out (btw, all hand painted with some brushes and acrylic paint)

finally got back to my paper airplane plans and think i finally got it ready to attempt flight.
biggest issue was CG. there was sooooooo much material behind that it limited my choices. i really wanted to do a twin motor with diff thrust but i also wanted it to be quiet. i have little 1306's that i could put on 4S and no problem, but it would be soooo noisy. in order to go quiet i had planned on bigger 2306's but once again due to the CG quickly killed that plan. so that left nothing but tractor config as an option.
in order to help with the cursed CG i chopped off a good section of the bottom fold section of the paper plane. this helped a bunch and without i don't think i would have pulled this off without going stupid bigger motor and battery. i still wanted to keep as lite as possible.
i really needed a ton of nose weight still so i designed and overly robust and heavy motor mount.
i thought it would be ok but duh, i had some real issues with the folding prop getting caught...
after some head scratching and problem solving, we went back to geometry.
problem solved.
again, the CG issues had me get creative with the rear control surfaces. i think it should work.... ?????
to save weight i went with stupid light wire for the servo to control horn linkage. i have it setup as an Elevon wing so when it is pulling up we are good, and when we swing left or right stick, we know we have at least 1/2 of them working.
to solve for this and to keep the control surfaces from fluttering i knew i needed to add some tension.
K.I.S.S. principle. the stretched rubber band gives enough tension when servos are at neutral to hold elevons perfect. i have full up elevator (which is all i need, not gonna be flying upside down), and plenty of left and right deflection with servo. the neutral control surface will be pulled slightly negative and held there by rubber band (ref- 1st pic above). or so i think. what could go wrong?
we will see tomorrow.

Created my first tape hinge. Not knowing what I was doing, I picked up both cloth tape and paper tape at the drug store yesterday. I tried the cloth tape, and this is what happened. I think I got the best result I'll ever be able to get with a tape hinge, and it happened completely by accident!
I laminated another paper layer to it with CA. After I crash in a horrible explosion and the rest of the boat is reduced to foam confetti falling into the Hudson, this fully assembled piece with be the only identifiable part found in the bottom of the crater.

Well I guess it’s starting to look like a plane!

Wow! thats amazing. I just hope that you will be able to take the duct tape off after you are done building, right?

Notthing is glued together yet, still laying things out. The duct tape is all that’s holding it together!

One 90mm 6s, the plane is 6.5 feet long so if I can keep it around 3kg then it should work a treat. (The fan is rated for 3.8kg but we all know it’s probably more like 3)

she flew like a dream. could not have asked for better. it floated really well off throttle and was almost silent on throttle.
only issue was the balsa prop guide i made broke on landing. i have a new 3D print to solve that problem.

This is the wing for the 13th Squadron F6F. I am going to start a build log since folks seem to want one. I have the pics so far. Just havent had the time to write it up. I have been procrastinating this thing for a while.

Does anything happen to those blunt leading and trailing edges?

Oh yeah lots of sanding! This is kinda my build style, simplify everything by making it oversized boxy shapes and then get carving with the file. Doesn’t make the most scale looking planes cause it’s all down to the madman with the file but it’s very light and stiff.(paired with carbon spars of course)

kind of looks like that plane in the movie FIREFOX
