This film shows a few of the stages of building the 37" free-flight rubber-powered Burnelli Transport concept aircraft from 1947. It then focuses on the methodical, eleven flights of the model's first trim session, ending in a beautiful soaring flight in Wawayanda, NY, where the many curious & vocal bobolinks had a front row seat or perch. Filmed by Tom Hallman on 5.25.24 with a Canon PowerShot SX20, and iPhones 11 & 14Pro. Music via the talented musicians at ArtList.io, who breathe life into my films.
First day notes with the Burnelli:
Started at 200 winds…then methodically worked up the ladder by
100 and then 150-200 turns with each new flight. Max turns in the 1900-2000 range.
Used the same motors (2 loops x 3/16" x 40") that singularly power the 27" Seafire & 28" Cauldron. Both use a 10" EB white prop...compared to the 8-7/8" props for the Burnelli.
The quick fix was more downthrust (twice), nose weight, right rudder via
1/32" thick gurney flap, and a touch of gurney on the lower left to help hold that right
turn…although I might remove it or adjust the location after seeing what the increased torque did to the initial power burst. I’d rather see the bird climb a bit flatter thru the first circle. With 500+ turns to go, I’ll need to keep an eye on the torque effect.
Cracked a bamboo skewer prop spar...twice, when it outflew the field, landing on the hardened dirt of the neighboring crop section. I’ll resolve these issues for the future. The 1/16” dia. toothpick rivets that I use are great for holding the blades in place, but I should not have had the one closest to the hub, as it created a weak spot in a heavy stress / leverage area.
I thought I’d be OK with shrink wrap tubing for the canopy but the hours of hot, direct
sun had other intentions, so that’ll be replaced with the good stuff, PETG plastic via the vacuformer.
I have growing concern for the lack of a DT on this model. But yes, a fantastic first day out with this unusual design.

That last flight gave me goose bumps. Such purpose and authority. Stable, yet sensitive. Balance of lift, thrust and bank. The lifting body gave it a uniqueness in flight that felt like an intelligence at the controls. Absolutely spectacular and one of the most inspiring free fliers I have ever witnessed. Congratulations and thanks.

Thx. Truly had no idea what type of flyer and peculiar traits she might have...especially after the first few tosses. Now I have a much better sense, and it's not as unpredictable as I had initially imagined. Just need to tame the rotational wing angle at the launch as she continues up the ladder toward max torque. I was surprised how quickly she gained altitude after a rather low first two circles on the final launch. As long as she's staying generally flat or stable after the power burst, I don't care which way she goes....although it is curious to see those long dives before pulling out, or not. Maybe a slight tweak on the lifting body's TE, rather than on the stab, as a more gentle adjustment? Fun stuff for sure.

@@godfrois2408 Good observation. That's highly likely. It was a bear trying to figure out how to line them up, but once determined, I'm left to react accordingly.

CBY-3 did great, it was very efficient but with only a pair of 1820's (Wrights) it was no match for a C-46 which was dirt cheap surplus, carried more and was faster. My Dad loved Vincent's aircraft and knew it was a winner but in airfreight, the numbers don't lie so RANSA had to pass but apparently Dad really pulled for it. BTW, he spun it at gross weight and apparently the 55 gal. drums filled with water weren't secured properly and shifted aft... and it still recovered.. Why anyone would do this is beyond me but apparently it was a demo flight and part of the maneuvers on the test card. FWIW.. I would like to build a slightly larger version, any chance of getting a copy of your prints for a starting point? 😎 The stuff on Outerzone is all earlier versions ... Tell me the cost and I will pay.. Blessings ! Al Robinson (near Memphis)

wow, so nice! I love the Burnelli designs and have built two such experimental r/c planes by myself, too. They were very floaty. But sadly I built them too light and both had structural problems. Getting the c.g. far enough forward was difficult, too. The NiCd-battery weighed as much as the rest of the plane and was at the foremost position.

the stall issue youre having happens with real aircraft as well, we call it the accelerated slip stream. the propellers are accelerating air over the aerofoil and giving increased lift, this is also asymmetric but i think you'll find a solution to that. but on twins, we land with power on because they just dont glide very well
@maxfliart
@maxfliart 3 ай бұрын
Thx. All of my twins have that moment of hesitation or even a stall once the power runs out. They tend to drop a wingtip, dip down a bit, then recover once the freewheelers kick in, where they're at least spinning again. This is where they'll flatten out and cruise about on their merry way, to one side or the other. It's a beautiful thing to see. In this one's case, at this early stage, I'm glad to at least see her float about at height, and sway one way or the other, as the air chooses to take her. I just don't want a spiral in the glide. But yes, a tweak is needed for that rapid descent in the downwind glide. She's shown that if she turns back, she'll correct herself. But I love seeing the new, individual characteristics of a given model. Each has a tendency that needs to be acknowledged, and tamed as needed. Therein lies the fun.

I think we get discouraged too early, causing adverse affect and accepting failure instead of trying to tweak ever so little til we accomplish success and take a win. I know this because I've accepted the failure too early in my own life instead of making little changes to see if it changes the outcome... This has been an eye opening video for me in the least to not accept failure too easily or too soon but maybe make small changes to change the outcome who knows might lead to a successful ending!

Are you up to swapping props, side to side. P-38 had outboard turning props, but that was supposed to be to make a better gun platform. From the pilot's seat both engines were critical. So minimum single engine speed was 140. Seems like you've created the perfect vehicle to test outboard versus inboard rotation.

No, they'll stay as they are, rotating over the top toward the wingtips. My mentors with FF rubber twins have resolved these concerns many years ago, and found this rotation to work best for our small, and relatively low RPM models, and I agree. All of my twins have been stable, using this approach. Thx for asking.

Had to watch this several times. The Burnelli Lifting Body is an aeronautical atrocity. You have three wings with four tip vortices dumping energy into the wake, making drag. Short separation between wing and tail is not good for pitch trim and stability. The canopy on the left fuselage will drag the left back. Sometimes. Didn't seem to be present in the glide test. May depend on speed and attitude. Using right rudder to fight that means they are fighting each other the whole time, wasting three times the energy. The rudder has to overcome the canopy drag and then some more to make the right turn. It might be better to let it go left. Everything else is symmetrical. The original had a central pod. First power flight clearly showed CG way too far aft. You've got to replace two heavy motors up front with the rubber motor going way to the rear. Fixing a trim problem with thrust line is not a good solution, only works under high power and varies with torque. Downthrust pulls the airplane down, not the way we want to go. Best to get he CG in the right place, use the thrust to pull the airplane forward. The sequence of winding may affect turn. Motors lose torque while resting after windup. Winding the left motor first will result in the right motor pulling more. As the power goes down, the effect becomes less. It doesn't seem to know which way to turn. It seems to want to go right under power and left when the power comes down, but there seem to be inconsistencies. It may be favoring one direction with the nose up and the other with the nose down. The balance between rudder and canopy may change with attitude. It's pitch attitude is inconsistent. The varying ratio between the motor torques may affect it. Very interesting dynamics. A challenging design. Often modelers can do better with a design than the original. You can tolerate a lot more crashes.

Are you shrinking the tissue before applying all the graphics/color to the tissue prior application to model.

Thru the process of adding the base color to the full sheet of tissue while it's on a frame, the tissue will naturally shrink from the water based paints. I figure that's plenty, rather than shrinking them first with water prior to painting. I'm using the older, and rarely available Micro-X True Old World Jap tissue which was pre-War...and it has a rather low shrink rate compared to more commonly available tissue, ie Esaki, Mt. Fuji etc. The bonus of course is less warping of structure.

,,,,do these propellers have a neutral spin in the hub/shaft.,,,after power is lost they keep spinning???,.....imo,....add ,if not,...tnx,,,pat,...land o' lakes,wi.

Yes, both have a free-wheel ramp so they’ll continue to spin after the power fades, but it’s still a lot of drag.

It's my own design, but the plans are not yet available. I based it on a 3-view and original pencil sketch from '47.
