Thanks for recognizing that, it is time consuming, and sometimes it's a pain (when I keep goofing up), but if it helps promote the hobby it's worth it!
I wouldn't recommend the 8" version, it's too unstable. The 6" is OK, but I'm working on the biplanes to see what those do, I'll eventually report my findings.
I also was thinking of angling the wing posts back, because I love the fat chord look and you can never have too much wing area. I hope you can share some experience about the VP props. They are too complicated for me at the moment, but yours looks really nice! Thanks!
Yes, the added design flexibility is what attracted me to Open instead of Limited Pennyplane - 18" wing but no restriction on the width, stab isn't restricted, rolled tubes are allowed, variable pitch props are allowed, and biplanes are allowed. I've been wanting to experiment with a super-wide wing for a while, next season I'll be trying a biplane version.
@@domoremath I built a bipe a couple years ago and found that similar to you, the wing had to go back. With the added verticality of the second wing the thrust line is way off. You can try some down thrust but it just seemed whimsical to me. Of course that's all before I found out you have unlimited tail in OPP
I’m building my first pennyplane right now! I’m keeping it simple and using the easy wing 2 plan. I modified it for ultralight. I’m stuck with the prop part (I’m using 1/32” sheet balsa for the propellers, so it will be solid. Any tips?
Take some 1/8x1/8 strip and roll it inside a creased piece of sandpaper until it is round all along the length. I like to cut at 4" length and mark at 2. 2" is where the shaft will go through. Then for your blades cut them out from sheet wood and sand them together (making them identical) then soak for a couple hours. If you don't have a pitch block, you can tie them to a coffee can and leave for a day. Then glue the blades to the spar once dry
Good advice below, I'd also recommend checking hippocket aeronautics for making props on cans, you can also get prop block forms from Indoor free flight supply. I wouldn't roll the spars inside of sandpaper, they often break that way, a better way is to use sanding blocks to roll it round as I show in the prop video for my F1R.
Thanks for the video. You have to be careful going down the path of "one wing good, biplane better......" because, if you're not careful, you end up at :- en.wikipedia.org/wiki/Horatio_Frederick_Phillips#/media/File:Horatio_Phillips_1904_Multiplane.png
Very informative video, so much detail. Thank you 😊😊
Excellent ss always! Thank you for taking the time to make this vid!

Very impressive. Thanks for the video.
It's a great plane, can you share the blueprint, I couldn't wait building it own my own！

Hi
Wieviel wiegt das Flugzeug,
Verkaufen Sie variable Pitch?
Sonst beeindruckend ihre Videos
The plane weighs 3.1 grams (with added weight), the required minimum. J & H aero sells VP props, but they've been out of stock for a while.
How many inches is the wing span, and stab
Wing is 18" long (maximum allowed), width is 8'", stab is 17.5" by 4".
Totally enjoy your videos.
Nice job!
Can't you cantilever the 8" wing past the end of the motor stick or is this not legal? BTW, Great video, Larry!
Thanks. Not a bad idea, that helps with the margin of stability, but I think the plane will still have problems due to the short moments.

@@HD-su9sq Check out my variable pitch prop build videos, it's simplified a bit there.
I didn't realize all of the restrictions lifted for open Pennyplane. This thing is seriously high tech!

@@RedstonePyroMan Right, that's important because you need to use a larger stab to get the margin of stability more forward.
@@domoremath back then I didn't realize I could have more than 12x4 in the tail. I'll likely build a new tail for it in the fall

impressive!
Amazing. That would last 2 minutes in my clumsy hands.
OOOKKKKKK

I've thought about making the Phillips Multiplane as an indoor flyer, would look pretty cool!
