Hi All,

Just managed to persuade Mrs H to pose with the latest project! :)

68" span, scratchbuilt. AXI 4120/18, 14x8.5 APC and either 16xGP3300 or 5S 1P Li-po's.

Hoping for 8lb AUW.

The model was inspired by the sweet flying characteristics of the little 40" Peter Rake-designed Waco I built a couple of years ago.

Very nice work Tim.
It looks like a very nice balance of strength and weight. Almost a shame to cover such a nice looking airframe. Please post pics when you get it covered. The last two pictures looks like a momma Waco with a little one under her wing :)
Best regards,
Jay

The big Waco had its maiden flight yesterday afternoon! Very sunny, but with a blustery breeze that made life very interesting for the 6 minute flight.

The rudder is fiercely powerful, and saw the model slewing back and forth across the strip on the 20 yard take-off run, but it rapidly accelerated and then headed skywards at about 30 until I could dial in a hefty dose of downtrim. Once levelled out it became obvious that the Waco really is going to fly well once I've sorted out the tail settings a tad.

The rest of the flight was spent doing 1/3 throttle passes for my camera-equipped mate, Bob, before fluking a real greaser of a landing and taxying back to the pits.

The specs;
AUW 8 lb
Wing area 950 "
Wing loading 20oz/ft
Power loading 78 watts/lb

I'm going to add a little more downthrust to the motor, reduce the elevator downtrim and tame the rudder before I fly it again.

The plan will be submitted to Traplet for publication.

Luverly model, Tim, and a nice size, too. I saw one of the small ones built from Peter's plans fly at our field today, and must say that I prefer models a little larger, like yours. I'll watch for the plans to be published.

Thank you, lads!

The second flight took place today, and model was a lot better behaved!

I'm going to try to host the video of the maiden flight, so I'll get back....

...and you must have had an expression on your face just like on your avatar:eek: .
That one always gets me. You're trying to hold it down, you know better than to drop throttle with a new plane that you're unfamiliar with, and work the trim lever at the same time. Just maidened a little plane like that yesterday. A real climber.

I had the Dumas kit Waco box in my hand about 5 times at the HS yesterday. Nice plane. Almost got it, will probably happen soon.

Brad,

QEFI is publishing the plans as part of the Traplet range.

They're splitting the article into a two-parter, so the actual construction details follow in the September issue.

Wonderful, Tim, my local Chapters bookstore reserves a copy of Q&E FI for me every month, and calls when it comes in, so I won't miss this one!

Thank you gentlemen!

The big Waco has appeared at a couple of UK fly-ins now, and really makes an impression on people.

Tim, read the review, very nice looking, It seems people are no longer scared when it comes to the larger end of electric models.
Unfortunately they require storage space (which i'm a little short of) so my Pilot models Tiger moth stays in pieces :(

Tim I don't know how I missed this post but all I can say is simply gorgeous! The in flight photos are quite realistic looking.

Now if I can just find QEFI here in Maryland, USA. My LHS used to carry it. They now tell me they can't get it anymore. :(

Hi again Tim,

While that is magnificent I was more interested in getting the magazine regularly moreso than the plans. However I see Traplet House will happily allow me to subscribe so the next spare $70 I have will order up a subscription.

Tim,

Are the plans a 2-part pullout? Or do you have to purchase the fullsize through Traplet? Wonderful design!

Cheers!

It's too big for a pull-out - even a two-parter!

Sorry, you'll need to buy the plan from Traplet themselves. In fact, I'm still waiting for my own copy........;)

That's what I figured. One could always hope though!

Cheers!
