Ten years ago I built a 13" rubber-powered free-flight Bleriot XXVI. This film documents its build, along with the first trim session in Pine Forge, PA. Designed, built & flown by Tom Hallman. Filmed with a Canon PowerShot SX20 & iPhone 6s. Music via the talented musicians at artist.io, who breathe life into my films.

Original aircraft info: Original aircraft received a Belgian patent in May of 1911, and was completed by September of the same year, although it appears to have never flown. No photos of the aircraft have surfaced, just the original patent 3-view, which shows that the aircraft intended to have a singular, retractable landing gear, with seven soft pads or skids under the lower wing.

I've updated the text with additional specs of the model, along with the original patent for the 1911 Bleriot XXVI.

I never tire of seeing this beauty in the air, and that final flight is just beyond! Great to see the early trials.

@jimbo2629 5 месяцев назад

The fore plane on canards is very vulnerable. You got that trimmed out. It wasn’t easy. Those early flyers are lovely.

@JefferyHall-ct2tr 5 месяцев назад

Hi Tom!: That was just AWESOME! Louis Bleriot would be proud! Although I think he may have lost his beret during that torque rolling flight! The final flight you showed was just COOL! No chasing! This video shows the challenges and the FUN of free-flight rubber power!

@maxfliart 5 месяцев назад

Thx, there were a few surprises during this session, but I fully enjoyed the process and was thrilled to see her actually fly. I tried unpowered test glides at home but they were impossible without some sort of thrust. Wild.

@michaelgillespie1206 5 месяцев назад

That last flight was beautiful, just perfect.

@motorbikedad58 2 месяца назад

Fantastic! I find myself searching for more and more free flight videos after witnessing the planes at West Baden Hotel in French Lick, IN.

@harrykeel8557 5 месяцев назад

The last flight was beautiful. What it's all about.

@johnhess351 3 месяца назад

For a scratch-builder, this is inspiring. For a wandering web surfer it is uplifting. That last flight brought a tear to my eye. Kind of like summing up the spirit of free flight. I think I'll build one, but maybe with reverse swept wings and a c.g. mounted gasser that could have made the balancing act easier for Louis.

That Rhône rotary was a sight to behold! I am impressed by the craftsmanship displayed in your videos Tom 🎉. I am way too fumble fingered to build that light, sure is a pleasure to behold❤

Tomis you put methodological of big think at diagnose. It is impress the take of time not rush you. Am have step every each one we make learn veeeeery particularly. Huzzah! Thank you.

Marvellous. Congratulations. I guess that initial surge of power and torque was a lot more than Louis Bleriot had to contend with. Noel

@jeffpiatt3879 5 месяцев назад

That soft New England grass is the perfect landing location. Beautiful model!

@williamrobinson7435 5 месяцев назад

That last landing shows Bleriot's pleased with this.. There's folks up there saying "what sort of plane was it?" and old Louis replies "Triplane canard pusher." and they chorus "nah, mate, you're havin' a LARF" (This version of Heaven is in London).. Now, he's pointing at his phone and going "BELIEVE!!".. As indeed are we subscribers! ⭐👍

The little ugly duckling learned how to fly . Thanks for sharing .

@johnlouden8978 5 месяцев назад

Magnificent! But, if this extrapolates to the real airplane, it suggests how twitchy those early airships were. Those guys were taking their life in their hands on every flight.

@maxfliart 5 месяцев назад

Thx. It appear this Bleriot was never flown so it’s especially satisfying to see her go. But yes, the original would have been a major challenge.

@paulwoodman5131 5 месяцев назад

Max was thanking you for his magnificent flight after so many years. 🥹. Thanks for sharing 😊

@michaelwhinnery164 5 месяцев назад

No way !!! In all of the years you've been flying how many spot Landings have you had ? And of them how many on the first day after trimming and testing ? This was Fantastic absolutely Brilliant.

@johnmajane3731 5 месяцев назад

So cool and so unique

@user-ng9uc3vu3k 4 месяца назад

Tom, .. nice one .. an eccentric arrangement, that you have been to get to fly, pretty well. I take it, the turn was counteracting the torque, .. so that a weave, in direction, from the torque (strongest at the beginning) is taken over, by the rudders? That last flight .. just like you planned it. .. :)

@aeromodeller1 5 месяцев назад

The wings seem to have less incidence than shown on the drawing. That increases the decalage and alters the longitudinal trim. A quickie with foam fuselage and sheet surfaces might allow working out things like that. We don't have the opportunity for wind tunnel tests. Test glide suggests Dutch roll, but the usual cure (more fin) is not available. Less dihedral might work, but would require a lot of work (rigging). 2:06 date says January 12, 1914. 2 loops, four strands, 33" long will take around 2,400 turns. It is already climbing at 700 turns, suggesting the motor is too thick. Starting with a thick motor is good, though, because it allows flights with the motor running out in the air, allowing judgement of descent trim. Here is where descent circle is set with rudder. Left hand pusher prop - motor torque rolls right. Many things are reversed. Right roll makes right turn, which will get problematical on high torque. Right turn under power is opposed with right thrust. That is, to get the thrust to turn the plane left, you point the thrust line right. Last flight with thinner motor, still starting off right with slight stall on transition to left. Much more turns will want some right thrust. I noticed you had a white tyre originally, but the plane ended up with a black tyre. White might be more historically accurate. In those days rubber was hardened and protected from sunlight with white lead, instead of the lamp black that was used later. I'm having as much fun watching these flights as you did flying them.

@maxfliart 5 месяцев назад

Thx for the comments. I’m glad ur enjoying the films. This one was definitely more of a challenge than most.

@fb4392 5 месяцев назад

Bravo! Another masterpiece suited for the Smithsonian. Monsieur Bleriot would be proud. He did seem unfazed though. On another topic, any trouble with ticks in the tall grass?

@maxfliart 5 месяцев назад

I’d flown there many times between 2011-19 but never had issues with ticks. Surprisingly. I miss flying there, since it has new owners, who turned it partially into a horse farm.

@michaelgillespie1206 5 месяцев назад

How did you go about making adjustments to the canard?

@maxfliart 5 месяцев назад

I used a soda can hinge nearly the width of the fuselage. It holds the adjustments fairly well.

@michaelgillespie1206 5 месяцев назад

@@maxfliart sure, that's simple enough. That last flight was beautiful.

@UguysRnuts 5 месяцев назад

Incredible achievement getting this thing to work. I wonder whether Louis Bleriot was able to successfully fly a scale model of the #26 before giving up on the configuration? Interesting how the single retractable nosegear design was resurrected a century later by Burt Rutan. Were you able to achieve an ROG?

@maxfliart 5 месяцев назад

Hmmmm…I’ve never tried or even considered it. But uv planted a seed.

@Bracenbit 5 месяцев назад

What about reducing prop pitch to reduce the torque at launch. It seems to settle down a few seconds into a flight. Of course the flight time will suffer some.

@maxfliart 5 месяцев назад

Thx. Surely an option but not one I would likely take because of the complexity of that adjustment.
