I do not know if you saw this documentary about the DC3.  It is a bit long, but an interesting film.


Thanks so much for sharing this @GuyOReilly .  It provides a terrific historical retrospective. I remember a couple of flights on DC3's when I was about 3-4 years old.

Sure makes one itchy to build a DC3!

Final report:

- connected the rudder and elevator servos.  Used very thin piano wire inside full length aluminum tubes.
- soldered the two sets of ESC wires to a JST battery plug and joined the radio wires via a small "Y"  connector.
- connected the ailerons to the two wing servos.  Used thin piano wire.

FINAL WEIGH-IN.  Total weight- 15.1 oz.
Fuselage- 4.7 oz
Wing with motors and ESC's- 8.0 oz.
battery 3S 800 mah  2.4 oz.

Will it fly?  Each motor has a max of 110 watts.  That's 233 watts per pound.  Oops.  I think I overdid it, especially since two separate motors produce more thrust than one motor with the same wattage.

Meets the Modeller's objective: "Always overpower a model airplane.  You can always throttle back....if you have to!"

Just prepped it for a maiden flight tomorrow (Sunday, June 20) at Rogo Field.
Put in a 370 mah 3 cell pack.  Fingers crossed.  Say a prayer.

The re-maiden went well today.  Managed about two circuits of the field and brought it in for a landing.  It did a cartwheel in the beans but it survived unscathed.  The only thing damaged was my ego having to do the walk of shame through the beans again. ;)\

Note the amount of "down" elevator in level flight.  That's how I had to fly straight and not-so-level.
