Kidde Smoke Alarm Beeping 1276

The six hours

Bound Speedway, this time by bus, but in spite of the insert, the important thing was to come, enjoy the show, meet other techkers and support the team.

This time we accompanied the 911-GT2 father, who enjoyed the irons as a member of the club.

A little more fed the bar, the emotions started this race as he began the fight for the drum. Instructions, tips, details, tension and the occasional beauty, is what we live at the racetrack just before starting the race.
The first official bar is the bar car racing Clop, a remarkable fact, which won both an interview and a live chanted for Todelar microphones.

laps completed courtesy officer is given the start and all the riders make the best of themselves and their machines in the early laps to gain positions in their categories. While on the platform begins hype clop bar to cheer.

and once you breathe again after the third or fourth round, our task is simple: keep an eye for a second in the team and pilots and send all the positive energy to reach the goal.

as always, our rc are the salvation for a little rest and relaxation, especially in the neutralization. Night falls and it becomes more difficult to identify our vehicles at a distance, but for the overhead light would be lost. Time to light the candles and celebrate this day. A cloud of smoke in the tent oldsmobile suggests that it could not finish, but we were wrong.


finished the race. We had the pleasure of seeing the clop on the podium for his riding in the Kia Picanto and the Subaru Impreza. and jump to the track "advantage of the situation" but the rain jumps at the same time forcing us to stop play.



and start our "career" walk to briceƱo, raining and cold, but satisfied. Of course the best time is when we finally take the bus home. Comes 2009 and the expectations of the club increases, we see that we have prepared the Colombian racing.

Referral Card Samples

Ciando is gerund.


Often, as in the modeling forums, is this the question:
Most drives do not have the option to reverse the direction of rotation. The drives are thinking that control a plane or a helicopter, devices that do not need this feature. Special drives for boats have this feature, but can be much more expensive, plus there is less variety. Principles


In DC motors (with brushes) the direction of travel is determined by the placement of the poles. If we invest, the motor rotates in the opposite direction.
In brushless motors (stepper motors) only to reverse two of the three cables, get the same thing. So the problem is the same in both cases.
to "reconcile" the invention will use three colors (Red, Black and White) for brushless and only two (Red and Black) for DC. Only use red and black wires in both cases.

two-way switch
In the photo above we have a two-way switch. We saw two rows of three contacts each.
How it works?
According put the lever, will contact the central terminal to the right or the the left. Now they are contacting the terminal N of the N center to the right. Same with the R at the R right. Among the top row and the bottom one there is no continuity, no current passes through the top row below. Change lever and then pass the stream from the center to the left.
is important to check with a multimeter that our switch operates as herein described.
How do I put it?
In the center terminals are the wires coming from and who would normally drive to the motor. In the case of a brushless cord stays soldier remains in the engine. Avante
all
For the engine will advance forward terminals right attached to the motor. When the lever is in place will contact the center N of the N on the right and the center R of the R on the right. The engine will move normally.

When we change the position we want to handle the boat "cie" (reverse). The solution is easy, in the left end probe the wires to the motor but folded so that the neutral line, the center will feed the left R and N R from the center to the left. The cables are reversed and therefore the motor is rotated in the opposite direction of any kind. These cables do not have to go to the motor unless you want, We will cross welding cables N cable into the top right and bottom left N. Also the lower right R to R top left.
How do you handle it?
Easy with a servo and a channel of our radio station not to use. Danger
system!
interrutor has to endure the intensity of current that powers the motor. Thus we find a switch that we hold the power that we deem to be passed through the (in amperes). Otherwise the switch will burn, melt, stop the boat lying in the middle of the lake. But this is not good, if short-circuits can damage the drive.
