Hobbies: Remote Control Car Motors

Remote Control Car Motors

Written by Michael Paetzold

All types of racing cars have different types of motors. Some have single or some have double. It is really confusing to try to sort out repparttar

difference between a single our double motor car. Plus a newbie into repparttar 142807

world of remote control cars gets easily disoriented with what is a 13 turn double or a 13 turn single…?

Well, in plain speaking language it refers to number of times repparttar 142808 wires are wrapped around repparttar 142809 armature. A 13 turn double would be 2 strands wrapped 13 times. A 13 turn single would be 1 wire wrapped 13 times. The double wires have more torque where as single wires have more speed. In general, it means that more turns means more torque but less speed and vice versa. That’s lower turns means lower torque and greater RPM. The number of winds describes how abruptly repparttar 142810 motor accelerates. Fewer winds would mean less abrupt acceleration and more winds would lead to smoother accelerations.

Torque basically refers to how much a force is acting on motor that causes motor to rotate. If there is more than one force acting on a motor then each of these forces shall apply torque. The net torque acting upon repparttar 142811 motor shall be repparttar 142812 sum total of all repparttar 142813 forces or torques acting upon a motor. It is usually required for cars racing on repparttar 142814 twisted tracks.

Remote control cars come with two kinds of motors: repparttar 142815 ones with brush and ones without i.e. Brushless. The brushless motor has windings located around repparttar 142816 outside of repparttar 142817 motor and repparttar 142818 magnets are located on repparttar 142819 moving motor shaft. A brushless motor does not provide any friction therefore provides higher RPM. But a brushless requires a lot of processing power that’s why it has not been a great success with RC trucks or cars.

Those Mountains in the Back - Identifying Your Old Family Photos

Written by Joe Bott

I read an article recently about repparttar

quantity of family photos we accumulate in our lifetime. I think it said somewhere around 1,200 in any given household, repparttar 142634

majority of which are unmarked. I can believe that—the unmarked part especially.

I'm horrible when it comes to jotting a note on repparttar 142635 back of my photos. "My photos" refer to repparttar 142636 ones that were taken by me or a living member of my family. I even have photos undeveloped from repparttar 142637 1980s, but I intend to get them developed "sometime real soon—as soon I get a chance."

It's repparttar 142638 same story with my hobby photo collection, which contains tens of thousands of photos. Most of repparttar 142639 photos are of note-less, name-less faces. If it weren't for repparttar 142640 photographers' marks, they would be of nameless, placeless faces. I refer to these nameless, placeless photos as "incredibly lost."

I wonder why many of our ancestors didn't put names on their photos. Was it laziness? I originally blamed sloth, but then I changed my mind. If you look on repparttar 142641 back of c1900 onward vacation snapshots, you can find notes like: "This is Uncle John next to Harvey Johnson's Boat," "Those mountains behind me are repparttar 142642 High Sierras" and "That's an Esso station were we stopped to fill'er up on our way to Lake Henry." It takes a lot more time to jot down "where" and "what" notes than it does to jot down a "John Hancock," and most vacation photos have something written on them. Yes, I've concluded that it was not laziness.
