1947 Lifting Body Burnelli Concept Aircraft - Trim Session #2

This film shows the second trim session of the 37" free-flight rubber-powered Burnelli Transport concept aircraft from 1947, flown in Wawayanda, NY. Filmed by Tom Hallman on 6.3.24 with a Canon PowerShot SX20, and iPhones 11 & 14Pro. Fantastic photos taken by Peter Kaiteris with a Nikon D3400 70-300mm. Music via the talented musicians at ArtList.io, who breathe life into my films.
Trim session notes:
The cracked right prop spar was replaced, along with the thrust plates, which were at the edge of holding their position beneath the flathead screws. This led to a slight shift in the thrust, which was adjusted at the field after the morning trim session. I continued preferring the right pattern at launch, through the use of 1/32" thick gurney flaps on the TE & right rudder.
But the tilt of the wing was too much, which prevented her from climbing at the power burst, so on the final golden hour flight, I trimmed the gurney flaps a bit, which helped flatten the initial power portion, giving her a wider circle and higher climb. I also added more nose ballast, which helped keep the nose down during the power portion, and did not seem to hinder the glide.
Max winds might not be as much as I had hoped, but so far, she's up to 1740. I'd like to get a bit higher, closer to 1900. She still has a slight stall during some of the glide portions, which will get more attention in future sessions.

    sky. sky. Breathtaking. Like a giant manta. Her lifting body is a great advantage in viewing from a distance. Nice job on the AOA and bank to get the most (for now) out of the Burnelli concept. Now if you could only make her come back to you.

    I built several Guillow's kits in the 70's as a boy, mostly because the were larger than the box when they were completed. I was always disappointed with the plastic kits that started with a big box and ended up with a small model. I never knew they could fly so well until I found your channel. If there are any groups in the Phoenix, Az area that still do this, I would build another. Thanks for another beautiful film.

    Lovely film Tom! What with the huge planar fuselage lifting surface and twin fins I thought this might just turn out to be one of those 'wandery' planes, the ones that have a mind of thier own and behave like flying weather vanes, indeed there was the odd little hint of this. Another brilliant bird! The original full size must have seemed well futuristic in its day. Wayawanda is looking lovely as ever, despite the 'plane attractant ditches'.. Beautiful skies in which to fly. Nice one Tom! 🌟👍

    Not this specific design, which was one of many concept designs in '47, but a version with the cockpit between the nacelles indeed has flown, as noted by a few who had commented on my original trim session feed. It's the Burnelli CYB-3. en.wikipedia.org/wiki/Burnelli_CBY-3

    Thx, Michael. That's definitely on my mind. Ironically, all of my other larger twins have flown better, after I forced them into the opposite direction, from their initial trim sessions. She seems to do what I ask of her, so it shouldn't take much to make it happen.
