Yak 54e is done
Friday, December 26, 2008
My brother-in-law just got his first RC heli. He loved it and flew it most of the evening. This is the new E-flite Blade mCX. It is a stable platform for beginners and great fun for experienced pilots. This version is the RTF and includes everything need to fly (even the AA batteries for the transmitter). E-flite did their homework on this one and came out with an A. This is a great way to introduce and get people into the sport. I may have to get one for myself........

So the Yak is almost done. I finished the main construction and radio installation. Everything went together fine with not major discrepancies. All that is need now is velcro (i ran out) for the battery, check the CG, and set the proper control throws. I should be finished this Sunday the 28th and be flying.
All said and done, this kit went together pretty well with clear illustrated insturctions, which were easy to follow. I also had some extra Apple decals laying around, so I thought would add them.

Well the project is officially started. I began construction as per the instructions, beginning with the wings. The ailerons were hinged and the servos add. One glitch was that one of the quick connects would not tighten on the pushrod, so I found one of a slightly larger diameter from another project. The wings are really quick to build; hinge the ailerons and mount the servos, glue in the control horns, and that’s it.
I next checked all the joints in the fuselage and added thick CA to important joints (firewall, landing gear supports, etc…). Since I am using the Scorpion motor, I had to slightly enlarge the hole for the main shaft, but the mounting holes are a perfect fit. The motor mount was glued into place using thick CA and landing gear was installed. This has been a straightforward and quick build so far. One could easily finish this ARF in one day.
Last thing done tonight was adding some of the decals, to give it that personal touch. The Scorpion decals came with the motor and Spektrum decals were ordered separately.

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).
