A New EZ plane Called "WHICHWAY"

[L Edge]

The wind hasn't quit for 2 days so decided to design another EZ plane that is different. After designing a delta, SR-71, circle, bobcat, flying wing, bipe, forward swept wing, B2 Spirit that all fly, decided to cross breed and see what variation I could come up with.

Trying to come up with a total weight of about 50 ish grams, scaled something out and hope it makes the limit.

Again, using Adam's Redi-board and it looks like a delta, no way, because I cut out another wing and glued it backwards. (OMG)

I also added some offset to the bottom wing for looks. Added some colored package tape to it and I'll introduce "WHICHWAY" to you.

Notice I left a lot of tail and nose so I get the CG right by cutting material off.
Got any guesses where the CG is?

So, with 2 wings and a fuse, I'm hoping it's a new bird. I know that I will have to use 110% concentration to keep the nose going for proper direction. The lower wing has to get ruled out. Left now is mount the electronics and fly.

can't wait to see her fly!

Looks a little like the Duplex Delta control line plane from 1959. A little easier to make something weird fly in the 2 1/2D realm, but it does show the CG on the plans. Start about 20% back from the top wing leading edge to the top rear intersection point.

After cellar testing, found out with the weight over 50 grams, it needs to be checked out by chucking real fast(small wing area). So have to wait until warm and calm day outside so to see if the twitchyness goes away. Found out this was a control line plane thanks to Brian B that was tough to fly according to some pilots.

A very interested plane, couldn't wait for calm day, wind was gusty and from low to about 8mph going up and down.

I cut out the video with bad throw angles and gust that flip it over my head on launch to shorten it and you can see what happens.
It rises, falls due to the wind until it comes from under and rotates it around and downwind.
Second run, it windsurfed across the wind and hit by a gust, rotated and went down stream.
Third run, rises and falls and makes it way with gusts until ground wins.

Impressed that EZ Pac unit flies with only throttle variations and differential thrust in such tough conditions. Need to fine tune CG without winds and see how it goes.

Learned how to cut and snip videos, but screwed up sound.

First thing I noticed in cellar, launching it requires a good thrust compared to my other models I designed. That's why I tried it in the gusty winds.

Once the top wing gets air under it , up it goes and oscillates like a sign wave. Very much like my SR-71, so if the CG is found, hope my throttle management (how about turns?) will dampen it out. Also, with a 50 gram weight for WhichWay, may not have enough thrust to handle the situation. Hey, that is what you call designing.
Next step, a no wind day.
