I first wanted to start with some of the components for my Yak 54.  The ESC, motor, and props arrived today giving me everything to get started.  I like to read over the instructions a couple of times over a couple of days.  I know this is a bit anal but it gives me time to absorb the techniques and nuances of the particular project.  Plus it gives me a chance to find any weird or new techniques.  Most importantly, it helps me understand the model and build it straight and true.  This usually ends up giving me a truly great flying model with little frustration.  Now, on to the esc and motor. 

I chose the Scorpion S 3020-16.  I have a couple of Scorpions around and like the motors for the great price and power you get.  Plus, they give you a great comparison chart for most of the other companies with great information on prop choices and specifications.  Here are some of the specs.:

Stator Diameter:  .................... 30.0 mm (1.181 in) 

Stator Thickness:  ................. 20.0 mm (0.787 in)

No. of Stator Arms: .......................... 12

No. of Magnet Poles: ....................... 14

Motor Wind: .............................. 16 Turn Delta

Motor Wire: ........................... To Be Determined

Motor Kv: ................................  1063 RPM / Volt

No-Load Current (Io): ...................  2.11 Amps

Motor Resistance (Rm) ..............  0.031 Ohms

Max Continuous Current  ................ 76 Amps

Max Continuous Power  ................ 800 Watts

Weight: .............................  152.3 Grams (5.37 oz)

Outside Diameter: .............. 37.56 mm  (1.479 in)

 

The ESC is the Turnigy Plush 40 with BEC with the programming card (which is not need but makes programming convenient).  It has the following specs:

·      Cont. current of 40A with 55A burst (>10 sec)

·      Linear BEC mode with 5A/ 3A output

·      2-5s Lipo and 5-15 NiMH

·      33g

 

The final parts are the servos and radio gear.  I have some Hitec HS-65HB sitting around (4 of them) so they will work.  I like the torque and speed of these servos along with the tough Karbonite gears.  The final parts will be the Spektrum AR6100 receiver and Spektrum 6Xi transmitter.  Since the plane has two aileron servos, I like to set up without the Y-harness and two separate connections.  This way I can mix in differentials and have flaperons (nice for slow flight and landings).
