Amazing Scratch Built Electric!!...30Lb. China Clipper Flying Boat


A little over a year ago, We were contacted by Mr. Dan Dewey and his father "Red". They explained over the phone that they needed 4 electric motors that would work on a flying boat. I told them to bring the model down to our facility.

They arrived at our facility with a model that had started construction in 1996. The goal was to re-create the Original China Clipper Flyin boat. They used the Original full-scale drawing reduced them and started building.....

The finished model has a 13' wing span and weighs 30Lbs. featuring Scale lighting both inside and out, detailed interior and exterior, detailed pilots and passengers, scale radial engines, scale size 3 blade props, scale hatches.

The model uses 4ea. Hacker A50-12L outrunners on 5S Lipoly turning scale 12x12 props with 4ea. X-70 Pro controllers. Each motor draws about 42 amps@756watts. Total power is over 3Kw.

Here are some pics with captions.

The Martin 130 China Clipper was indeed an incredible flying boat...It started the long range 4 engine transport revolution,in many ways.

Sometimes Sikorsky S42s and Boeing 314s are also called China Clippers, but the name is only perfectly accurate for the Martin 130, as is modeled here.

That is a heck of a great model!

The water taxi test went ok, the model was tricky to control at part throttle taxi speeds. The left wing is heavy and weight is being added to the right wing. Also the motors are set at 0 degrees right thrust. about 1.5 degrees of right thrust is being added to the motors.

The plane is now at the London Bridge Seaplane Classic being held this weekend in Lake Havasu, Az. here is a link for the event:http://www.deserthawksrc.com/page6.html

PanAm Clippers


PanAm referred all of their fleet as "Clippers". The "XXXXX Clipper" name was carried on up until the end of the company. In fact, PanAm trademarked the clipper name. When Piper produced the PA-17 Clipper, PanAm took legal action, forcing Piper to drop it and change the name to Vagabond. That's why there is a PA-15 Vagabond and PA-17 Vagabond. Do a search on PanAm and you will probably find all the clipper names used by the company.

This is an awesome build, I can't wait to see the video.

Gasp!
I wonder if they mortgaged the house for the power systems?
A real beauty though. I hope all goes well.
We'll just have to wait until after the event to get a report.

May I ask where you acquired the propellers?

I would venture to say they are 3-blade VarioProps on 12C hubs because it appears the root joinals can swivel when not locked by the spinner. But the spinner (the screwable hub nut) looks a shade different and scale blades for the 12C hub don't come in 12-inch diameter.

What Mike said...

There were 10 S42s in the Pan Am Clipper fleet (don't have the names), 3 M130s (Hawaii, Phillipine, and China Clippers), and 3 314s from Boeing (Yankee, Dixie and ?).

Gorgeous aircraft all, with interesting histories!

Maiden Flight


Fiday ended up being High winds with white caps on the the water, the maiden flight was postponed until better weather.

Saturday was perfect, no wind and calm water. The model was readied for flight all surfaces double checked and with the all packs charged the model was moved to the water. the model taxied to take-off position and the throttles advanced.

The model smoothly accelerated and lifted to about 2 feet above the water, then VIOLENTLY Pitched nose high and Snapped over, the wing tip caught and the the model flipped inverted , resting in the water upside down!!

Both Dan Dewey and "Red" were shocked and saddened by the crash, the model was dragged to shore (To Heavy to lift into the recovery boat as the wing had filled with water).

Dan stated the model will never fly again..............

That's a bummer. Hope they can get it all fixed up to at least be an awesome display model.

Has anyone got any theories as to why the model would have suddenly pitched violently nose up, it almost sounds as if there was a cg issue or water had got into the fuselage and worked it's way towards the tail on takeoff. It's a shame she'll spend the rest of her days as a hanger queen, she'd have been quite a sight in the air if she'd been sorted out.
