My big Monobloc ... something different!

Entirely scratch built 1/4-scale 1911 Antoinette Monobloc.

13' wing span with 5600 square inches (39 square FEET) of wing area.

Internal wing warping. Pull-pull cable rudder and elevators. Stabilizer has separate servo controlled trim mechanism - leading edge moves up and down.

Projected weight ~30 lbs.

Astro 90 with 2.9:1 belt drive. Astro 204D esc. 40 3000 mAh NiMh cells. 24-16 or 28-14 prop.

I have been working on this project for a couple of years now and at last it is almost time to fly. Pre-cover taxi tests look very promising.

The full-size prototype was classically overweight and underpowered. Mixed accounts of flight performance. Given that she weighed some 3000 lbs and less than 100 hp from the fuel-injected V8 motor it is probably that there were only some straight ahead hops. I hope to do better.

More pictures after she flies!

... and the full-sized airplane. A very low-drag airplane compared to other 1911 airplanes.

Wow, that's really something. Very nice work. Looks like there isn't a lot of vertical fin area. Any idea how the original faired in yaw stability? Best of luck!

My mind is boggled!

That is a truly awesome project, all the best with test flying her. Has to put you up there with Jim Collin and Jerry Smartt as a "Master of the Monstrous".

Regards

Wow!
This is absolutly fabulous! I was not aware of this plane. Very unique and the lines are wonderful. I think I need to add this to my long list of must build. You are truly a master craftsman with a great eye for the charm of the past and the ability to to bring it to the present.
I certainly want to here more about the details for your controls. Please more pics and video is a must for the maiden for sure.
I wish I could be there for just one flight.

P.S. by the way... that thing is HUGE!

VanJaershky: Yes, the tail volume is a bit shy of what we would consider acceptable today. I built a 12" span test glider to examine the stability question, and with a forward CG it seems ok. Sure hope so given the amount of effort that I have expended

Mistairjoe: I did a LOT of research over several years and acquired what I feel to be all of the published articles, drawings (ALL of which had huge errors) and photos. By good fortune, an acquaintance located some very rare unpublished photos too. From this collection I drew my own plans as a 3D wireframe.

Rudderman: Of course!

Actually, I'm going out to do some post-covering taxi tests tonight, with a flight possible if the weather is perfect - which is not likely.

Tomorrow it is off to attend the Dawn Patrol at Molalla. Again, a flight is possible if everything is perfect.

After spend untold hours during the last month getting her covered and ready to run, I am in no hurry to fly. Besides, she still need those signiture wheel fairings and some paint to look right

Wow!! That looks beautiful.

I would love to see more pics, especially of the wings. That's a real work of art.

Good luck with the maiden!

Her she is with some clothes on

Actual weight is 38 lbs ... still less than 16 oz per square foot.

Had a rudder pull-pull cable failure today during a high speed taxi and the left wing took a bit of a hit.

The airplane is very stable during the ground run and was just below lift off speed when the failure occured ... could have been much worse.

I'll have it repaired in a couple of days.
