Title: Jenny at the NATS
Post by: John Witt on July 17, 2011, 09:45:09 AM
My brother put together this video and posted it on Youtube.   The first flight was Saturday morning in wind that is about the limit for flying this airplane.  This was an official flight and didn't score well because I didn't dare do much more than fly around at rather high speed.  Second flight was a test flight on Sunday morning before the official flights.  I was lucky to have pretty good weather (near calm winds) all day, except for the second official flight which had what seemed to be a little thermal over one corner of the pad.

The Jenny is a joy to fly in conditions like that.

Great video of a great Jenny.  Without the wind it does very good take offs and landings.
Glad you came to the NATS.  It was a pleasure to meet you and your brother.

John - based on the video it sounded like you have eletric power, what motor and battery do you have installed, what is the wing span, weight of the model?

Fred,

The Jenny is built from a Proctor kit.  There is a complete build thread here:  http://stunthanger.com/smf/index.php?topic=12978.0
There is also a listing of the power train in the electric airplane "List Your Setup" section.

The Jenny is about 10.3 lbs, with 1400 sq inches of wing area.  Prop used in the videos is a Xoar laminated wood 17-6.  It actually flies better with a scale scimitar paddle bladed prop that is 17 inch diameter and an unknown, but low, pitch.  I don't use the scale prop because they cost $35 each.  The motor is 1650 watts and uses Clancy's U-Tronics control through a Castle 100A ICE ESC and Turnigy 6S 5000 mAh battery.

Thanks for the nice comments,

John

Great video of a terrific flying Jenny.  Looks like they had you on the racing pads.  Glad you did well at the NATS. H^^

Beautiful!

When 4 cycles were gaining popularity in C/L Stunt I considered building a Semi Scale Jenny Stunt job. Now I wish I had. I still have the plastic I built!

Well done...

Congratulations, John.  Mark Scarborough and I judged your plane at the NW Regionals and were totally impressed.  It was apparent that you had a beautiful flying plane there, but suspected that it could be a bit of a handful in the wind.  Your plane did some of the most beautiful take-off and landings ever in the scale event.  It was a joy to judge and very difficult not to award top points for the maneuvers.  Way to go!

Thank you all very much.

I'm still planning to finish out the cockpit detail, you know how it is...never finished, just another project comes along.  I'm seriously considering the Proctor Albatros DVa as a new project after seeing one of them at the Nats.  It would be RC, though, at about 25 lbs too big for UC and current delivery is about 10 weeks, which will put it in the winter projects list.

Muncie is quite a drive from Seattle, but it was a pleasure to meet Alan Goff, Jack Sheeks, John Brodak, Jim Fruit, Clancy Arnold, Chuck Snyder and the many other talented modelers in attendance.
