I finished my Stryker RC plane today. The only thing I had left to do was mount the motor, which I am very pleased with. I decided to use the stock motor mount with a very small adaptation to mount the Tower Pro 2409-12 motor<\/a> that I bought from unitedhobbies.com. I used a technique I read about on one of the RC forums (rcgroups, rcuniverse, wattflyer) involving the plastic lid of a soda bottle. Since the 2409-12’s mount holes are in different positions than the stock motor mount, I drilled 3 holes into the bottle cap to mount into. I used my razor blade to chop away the vertical cylinder of the lid, leaving only the flat disk, which fits perfectly inside the Stryker mount. Here’s a picture of the sode bottle lid bolted into the stock motor mount (on the other side sits the aluminum mount that came with the 2409-12 motor):<\/p>\n

<\/a><\/p>\n

The bolts included with the motor from unitedhobbies.com were too short to fit through both the bottle lid the stock mount, so I had to buy some 2-56 metric bolts from Radio Shack for $1.99 (the motor 2409-12 mount’s holes are drilled for a 2mm bolt). From the back, you can see how the three bolts protrude with plenty of room:<\/p>\n

<\/a><\/p>\n

The bottom bolt fits into the bottom hole of the stock mount, but the other two sit at approximately 11 o’clock and 1 o’clock. The mount is amazingly sturdy as the bottle cap and mount are squeezed in between the bolts’ washers and the aluminum mount. While working with the mount, I realized I needed to remove the bell from the motor mount to accommodate my fat fingers. After I mounted the aluminum plate, I put the motor back on using the two Allen screws. Here’s what it looks like ready to fly:<\/p>\n

I did some glide tests and partial-power tests in my backyard today and it seems to fly level and smooth. I had to spend some quality time with my DX6 to adjust the servo travels because it seemed that when I applied full back stick, the right elevon moved farther than the left elevon. I knew that this would cause the plane to roll, so I reduced the elevator channel’s travel down to 50% in both directions. That’s what it took to make the two elevons move evenly with elevator. I setup low rates at around 70% for both elevator and aileron channels and they seem pretty good. I think I will probably fly the maiden flight with the elevator on high rates and the aileron on low rates. The maiden flight will probably happen this week some time.<\/p>\n

For the maiden, I’ll try to borrow a friend’s Align 2200mah 3S lipo, which should provide lots<\/b> of power. If it’s not available, I’ll use my 8-cell 1500mah NiMH pack. Currently the CG seems to be spot on with the 8-cell pack.<\/p>\n","protected":false},"excerpt":{"rendered":"
