RE: JUST ARRIVED -- SOMENIZED YAK-54, 49" ELECTRIC
Hi Guys,
I had few hours to kill tonight so I figured I would tackle some of the more time consuming stuff. I have to back up a little and talk about servos which I installed the night before. I decided to go with JR 386s. They are the most expensive ones in the class however they provide the most accurate and highest torque among the choices which are MC 35s weigh .59oz with 30in/oz torque, 386’s are 53 in/oz weigh .83 oz, HS80 36 in/oz, weigh .67oz. The manual also calls for using 40mm arms on all servos. The elevator and rudder are pullpull each with one servo each and one servo for each aileron. For now I am also going to use my existing JR R2000 RX and replace with a Spread Spektrum later.
Servo installation was pretty straight forward. I did use the supplied servo screws and long 40mm arms. However installing the wheels and wheel pants is a little tricky. The picture shows a method I used to accomplish that. Basically I had to tighten two nuts together in steps so I found that having a vice to hold landing gear is a good help. If you don’t have a vice, then install the gear into the fuse and using long nose pliers tighten it up. Then I prepare the motor for installation. This motor is set up as an outrunner so the outside housing shaft adapter needs to be installed. The mounting bracket is installed on what would normally is the front main housing. So the front is held and the housing turns. (see picture) . A note on the ESC programmer. I still haven’t been able to make the USB Dongle to talk to ESC but since the default setting is acceptable its not a show stopper. Any ideas why my computer can’t get data from or to ESC. USB is set up right.
Tonight I clocked another 2 ½ which puts the total at 5 ½ hours total..
Signing off for now
