bonjour,
Je repasse par hazard, et je vois que certains ont la nostalgie...

J'ai acheté voilà plus d'un an le fameux timer,(il faut un variateur bec) je peux vous dire que cela fonctionne parfaitement. Je mettrais une photo dès que j'ai un moment.

Pour le départ, on presse un petit inter, puis le moteur prévient par un bruit de sonnerie puis il tourne 30s au ralenti le temps d'aller à la poignée. Le temps de vol est programmé par exemple sur 6mn puis il prévient par unne coupure, et ralenti pour la coupure total. Le pied quoi.
Je peux vous dire q'un avion F2B accro de 2kg max tout équipé avec un bon brushless avec une 13X6.5 un accu lipo de 5s de 3000 mAh 25c 18,4V c'est parfait. Mieux que mon Stalker 1Occ!!

Je les commande directement à wnieuwkamp@gmail.com
Voici la notice fourni par le fabriquant, un détail important, il peut faire la double carburation de nos bons vieux thermiques dès la figure commencée:

F2B Electric controline timer developed by Wolfgang Nieuwkamp

Status: May 2008

1. Principle
The timer stabilizes the line pull to about 2,7 g during all flight maneuvers, independent of line length and wind directions. Lap times are dictated by the line length.
This is done by measuring the centrifugal force with an acceleration sensor. Overhead you need between 17 % and 20 % more speed than at level flight, to give the same tension! Decreasing battery voltage is automatically compensated. Against the wind, the speed will be increased, with tailwind the speed will be reduced. The microprocessor measures the centrifugal acceleration, and adapts the pulse length for the controller between 1 and 2 milliseconds (1 ms activates the brake, 2 ms means full speed).
For start, a helper or a stooge is still required, for safety reasons.

2. Controller requirements
The controller has to be equipped with a 5 Volt BEC.
The controller has to be set into self-learning mode, brake activated, no speed regulation, fast reaction to pulse length. Not into Governor mode, Never in „Heli“ mode! „Sailplane mode with brake“ is suggested.
A programming card is recommended, if available for your controller.

3. Timer location
The y-axis of the timer has to point to the outside of the circle. The x-axis has to point forward. The push-button should be accessible by your finger. The timer should be located as far from the controller as practical. The best place is above or slightly in front of the centre of gravity.
Weight: 9 grams.
Dimensions: 52 mm x 33 mm. (The 52 mm can be reduced to 48 mm by careful cutting.)

4. Program
Connect the battery to the controller just before the flight.
A short pressing only generates 1 ms pulses during one second (for safety reasons). When running, a short hit stops the program.
The flying cyclus is started, when the button has been pressed for more than 2 seconds.
The following happens:
The pulse length is increased from 1 to 2 ms, stays at 2 ms for 1 second, then decreases to 1 ms (brake is activated shortly), then increases to give slow running during 12 seconds (time to walk to your handle).
Now the regulation is activated. Since the model is standing, there is no centrifugal force, so full speed will be activated, and the helper can release the model when the pilot is ready.

After 5 minute and 30 seconds the motor will burp two times, run for another second, and the speed will reduced until the propeller brake is active.
Disconnect the battery as soon as possible, to avoid further discharging. Record the amount of mAh needed to charge.

5. Adjustments

MAKE SURE THAT THE REVOLVING PROPELLER CAN CAUSE NO HARM!
Keep the space in front the propeller free, just in case the propellor comes off the shaft!

The only thing that can be „adjusted“ is the propeller diameter and pitch.

Preparation: Mount your motor on a stable stand. Connect a suitable DC Ampère-meter between battery and controller. Securely mount a propeller with the maximum diameter and a low pitch on your motor. Connect the controller with the motor and the battery. Connect the timer with the BEC. Attention: The yellow marked pin is connected with the pulse! Wrong polarity can damage the µprocessor.

Hold the timer completely horizontal. Press the button shortly. The controller will beep, but nothing else will happen.

Press again, during more than 2 seconds. When the controller is programmed correctly, the flying cycle will start. When running at full speed, check the current, and stop the timer by pressing the button shortly. Adapt the pitch until the desired current is reached.

Now you can check the regulation as follows:

Tilt the controller so that the y-axis is pointing downwards. This will change the target acceleration in y-direction to zero g’s. Still holding vertical, press more than two seconds. When started, hold again horizontally. By tilting up and down, the motor speed will increase or decrease. This completes checking of the regulation, and the motor can be mounted into the airplane.

6. One minute test runs.
When the x-axis of the timer is held upwards when pressing to start, the running time is reduced to one minute,

JMP 2 function Timer for Control-line electric model

Généralities :
The JMP Timer allows control of total motor run time, part throttle run-up, and optional motor sag warning for "end of tank", together with control of a gear retract servo..
It controls your model's ESC. Thus all types of motors can be used, brushed or brushless are no problem..
Motor run-up time can be programmed in 1s. steps between 1s. and 100s.
Total time can be programmed in 10s. steps between 10s. and 1000s
Accuracy is ensured by programming times in a learning mode.
The data lock feature prevents unintentional modification of the programmed parameters.
The JMP Timer weighs less than 1 gram and drains less than 0,5 mA. It operates from 2,5V to 5,5V

How to connect the timer :



1) Operation :

- Plug the green insulated male plug of the timer into the receiver socket of the ESC. Plug the retract servo connector onto the black male plug of the timer. See drawing above for correct orientation of connectors.

- Connect the battery to the ESC. The ESC becomes armed.

- Press the button and hold down.
After 2,5 s., the motor accelerates to full speed and remains at full speed until the button is released. When the button is released, the motor slows down to the programmed run-up speed.

- Timing starts upon release of the button.

- Once the run-up time has elapsed, the motor accelerates to the first flight speed.

- After 10 s. the retract servo moves to the gear retract position.

- After the first flight speed time, the motor smoothly and progressively ramps up to the final flight speed, so as to compensate for a dropping battery voltage.

- The retract servo moves to the gear extended position, the motor sags two times, and the motor continues to run 5 seconds before stopping.

- At any time during motor run timing, pressing the button twice will stop the motor.

- A test mode allows for convenient checking of the memorized time values.

…/…

2) Programming : (NOTE : programming is possible only when data lock is deactivated ! - see § 4 -)

- Il is possible to independently program the following parameters:
- Motor run-up time (from launch in 1s. steps)
- Total motor run time (from launch to stop in 10s. steps)
- Motor run-up speed (64 possible steps from 0 to 100%)
- Motor first flight speed (64 possible steps from 0 to 100%)
- Motor final speed (64 possible steps from 0 to 100%)
- Data lock/unlock

- Programming is performed by pressing the button according to a preset sequence

Total motor run time:

- Release the button, press again within 1,5 second and hold.
- After 2,5 seconds, the motor starts to full speed.
- Release the button. The motor slows to run-up speed.
- After the run-up time has elapsed, the motor goes to first flight speed.
- After 1/10 the first flight time, the motor starts ramping up.
- When 1/10 the total time has elapsed, the motor has reached final speed
- The motor stops, and the timer exits test mode.

4) Data lock / unlock :

The data lock feature protects the memorised parameters from unintentionnal modification.
- Press the button 5 times and hold.
- The motor bips 5 times. Keep the button held down.
- After 5s., the motor bips 3 times to confirm data lock or 2 times to confirm data unlock.

Multiple-Function Electronic Timer
EFLA172
The E-flite C/L Timer has been designed to deliver control of an R/C ESC for use in an electric control line model. The
timer has a very low weight of only 3.2 grams and is very compact in size. The timer is programmable and has a second
function for controlling other features on your model such as retractable landing gear. The main features of the C/L
Timer are listed below:
1. Programmable timer settings in 1 minute increments
2. Motor rpm is adjustable from off to full throttle
3. Motor cut-off alert in flight
4. Gradual motor rpm slow down prior to cut off
5. Optional control for items like retractable landing gear
6. quick and easy stopping control
Introduction of Use
The top of the timer has the start button and Motor RPM adjustment knob. The label is located on the bottom of the
timer.
You will note the label is on the bottom of the timer. On the left side there are two sets of pins. These pins are for the
ESC and second function. Please note the labeling of the ground wire, positive wire, and signal wire on the left side of
the timer. This labeling is correct when viewed from the bottom of the timer. The ESC port is on the top of the timer
and the Optional control is for retract servos, etc. This is the port that is on the bottom of the timer.
In the middle of the label we show the Motor RPM potentiometer. This potentiometer is located on the opposite side of
the timer. To increase motor RPM you turn the knob clockwise. To decrease motor RPM you turn the knob counterclockwise.
Please note that if you turn the knob fully counter-clockwise the motor will not run.
On the right hand side of the label we show the Start button. This button is located on the top of the timer. This button
controls the duration of flight as well as the emergency stop ability of the timer.
Battery power required for timer operation must exceed 5 volts as a minimum voltage.
Istructions for Use
Plugging in the ESC and optional device
1. Plug the ESC into the timer ensuring to align the ground and signal wires. The ground wire is usually brown
or black. The signal wire is usually orange or white. If you plug the ESC in backwards, the unit will fail to
operate. You will want to plug the ESC onto the top of the timer.
2. Plug the retract servo into the timer ensuring to align the ground and signal wires. This will plug into the
lower set of pins on the timer, or under the ESC.
3. If using the optional device (designed for retract operation) you will find the retracts to raise 15 seconds after
the motor begins to run. The retracts will lower 18 seconds before the cut-off warning occurs.
