The pulling out of the loop "a little funny" was probably due to the fact that, without tip fins, your plane was essentially operating as a true Flying Wing. The old Northrop XB-35s and YB-49s had a tendency to "hunt" about the yaw axis after turns, especially in turbulent conditions. Your plane was probably experiencing the same effect. Otherwise, it looked like it was flying beautifully!

Without the end fins, a delta wing might be more prone to tip stall when flying slow and attempt to make a steep bank.

I am into the foam board building stuff..Its a whole new ballgame now days with the creativity and all.. Good job!!

[@ProjectFlightDesign]

Thanks for noticing that! I added all of the info in the info section

[@ProjectFlightDesign]

Thanks! It was a fun time

[@Donatillo1961]

so is this a three channel delta system ? Throttle and ailerons ? I want to make one !

[@captarmour]

It would be interesting to try a regular airfoil like Clarke Y without fins

[@bobdaeronort]

Try them with fins below the wing only.
then try them ventral and inboard either side of the prop.
Check out my Ho-229.

cool ...enjoy watching your video's,,keep well ..South Africa

[@ProjectFlightDesign]

Thanks! More videos to come

[@wattwaster5936]

Others have done the same thing by leaving a flat spot near the wing tips to produce drag. I suspect you have the same sort of thing at work.

[@vatovega]

Do you still fly in Chicago ??!

[@itch4travel]

Can your Delta wing be converted for water landing?

[@aidanreece1578]

nice vid

[@voldelurubu619]

interesting !

[@OrignalRecipe92]

do you have plans for these wings available?

[@ProjectFlightDesign]

I do! Check out my other videos or my website

[@leneanderthalien]

your design is comparable to the real size Aeriane Swift light PAS ultralight motor glider...

[@brosius85]

cool experiment. please don't call them mini zephyrs though. seriously. if you flew a zephyr you would know why it is offensive.

[@ottyflyer1]

What a waste of a perfectly good aircraft.
