Hi

I have been using a Planet T5 for about 18 months without any problems until now. Setting up the radio in my new build I switch on the receiver to bind it to the TX and the motor runs at full speed. I can disconnect the motor and bind the receiver and then reconnect the motor and all works OK except that when I switch on, the motor runs at full speed until the receiver has found the TX.  I am using a 12v battery with a Viper Marine 20 ESC, a 540 motor and powering the receiver via. the esc. I have 3 other boats using a similar set up but 6v without problem. Any ideas

Once your receiver is bound to the Tx it doesn't need doing again, so you should switch on the Tx first and the Rx second wait for the light on the Rx to glow continuously and away you go.

Your motor may well race until the rec locks with the trany. Once the two are locked then the motor should then stop and be under the trans control. Different speed controllers do  different things until they are controlled by the rec. John.

Are you doing the ESC set up as per the instructions ?
With the Mtronics the centre point needs to be set.
Otherwise you dont have a dead spot and on switch on
the control tends to go full ahead.

Have you pressed the set up button first on the viper within 2 seconds of switching on so that it sets itself?  If you dont then it automatically runs at full speed regardless.  You may also need to set the reversse brake too as per the instructions.  I fitted a Viper last night for a boat and didnt reach the set up button within 2 seconds and it immediately went to full power - switched off and started again and presset the set button and sorted.

Many thanks for the reply's.

The difference that I am experiencing with my latest boat is that the motor runs full speed for about 10 sec. This does not seem long but with my other boats the motor only runs for about 1 sec. The only difference in the setup is that this boat is 12v, the others are 6v,   I have done the setup of the esp as per the instructions and all works well after the initial racing engine mode.  I have read on another post that the latest receivers have 
a circuit to prevent the engine going onto full speed if it loses transmitter signal, could it be that the new receivers take longer to log on to the TX.
I will try swapping receivers with one of my other boats.

Hi Don

You are quite correct - the latest 6m receivers do have a built in failsafe that defaults to 'throttle closed' on the throttle channel and 'last good position' on the other channels in the event of signal loss. Did you notice if the motor was running forwards or in reverse during the startup period?

Cheers

hi Jon
I have had another look and the motor does run in reverse. When I switch on the motor starts to run as soon as the red and green lights on the esc stop flashing and continues to run until the light on the receiver stops to flash. This suggests to me that these new receivers take longer to log on to the tx. I haven't had chance to swap recievers with one of my older boats yet but I will report back when I have tried.

Another thread I saw here suggests that the TX defaults to sending a 'slow' signal until it is operated - as a safety feature. This is, of course, full reverse for a boat or car...

You should, of course, always turn your TX on before your Rx. If the TX has this safety default, it should be turned on, then the throttle stick moved to full speed, and back again to full reverse. Then move it to 'neutral'. Only after this will the Tx be sending out a 'slow' signal. Then turn your Rx on.

I haven't tried this, but the explanation made sense...

The above is correct, the latest R6M receivers have a failsafe function, factory fitted, that cannot be bypassed. It is designed for Flyers to prevent the model running up the motor before the TX and Rx have had a chance to bind. On an aircraft that is throttle all the way down, on a boat, that is full astern ( or full forward, depending on how the motor has been hooked up ). The only way I have bypassed this is to set up the throttle on the other stick,which is the best option with your multiple models on one Tx. Or change the sets mode over via the little switch inside the set. This will transfer the throttle failsafe function to the other side of the set, but you will have to swap the throttle servo positions to the Elevator Channel (  I think? ) on all your models.
Or in English. Changing the set from Mode 2 ( Left Hand Throttle ) to Mode 1 ( Right Hand Throttle ) will move the Throttle Failsafe function from your ( assumed ) ratchet channel to the other, sprung channel. This will then become the sets Failsafe Throttle Channel, while you use the stick you are used to....



I think its been a long day and the above could be explained better... need a lay down in a darkened room....

Quote from the little bit of paper in the latest R6M receivers...
ADDENDUM SHEET
PLANET R6M RECEIVER
IMPORTANT USER GUIDE

NEW FAILSAFE FUNCTION FOR THE R6M PLANET RECEIVER
FROM THE FACTORY SETTING (THROTTLE REVERSE SWITCH IN THE NORMAL POSITION) THE FAILSAFE IS SET TO GO TO THE LOWEST POSITION IN THE EVENT OF ANY SIGNAL LOSS. THIS FUNCTION IS NOW FACTORY PRE-SET SO NO SETTING UP IS REQUIRED.
IF YOU REQUIRE THE THROTTLE TO WORK IN THE OPPOSITE DIRECTION ( IN REVERSED ROTATION ) THIS IS NORMALLY USED WITH SOME RC BOATS OR AIRCRAFT WHEN USING A SERVO, THEN FOLLOW PROCEDURE BELOW:
MAKE SURE THE TRANSMITTER AND RECEIVER ARE SWITCHED OFF
REVERSE THE THROTTLE CHANNEL FROM THE TRANSMITTER
RE-BIND THE RECEIVER TO THE TRANSMITTER IN THE NORMAL WAY
READY TO USE

WARNING
FAILING TO RE-BIND THE TRANSMITTER TO THE RECEIVER WHEN REVERSING THE THROTTLE CHANNEL WILL RESULT IN THE THROTTLE GOING TO FULL POWER IF THE SYSTEM GOES INTO FAILSAFE

I cannot imagine a situation where you would want to deflect a servo fully up as a failsafe position, except maybe de-thermalising a glider...anyway, thats what they say in the latest R6Ms.

The problem with the mode swap is that the other channels appear to have a failsafe as well and that is 'last good position' so if you happen to have the throttle wide open when the signal is lost the failsafe will keep it open (At lease that's what mine did). I guess this is not too bad in a slower moving model in that it will just continue on its path until it reaches a bank but for fast boats............

[lockkeeper]

I have now followed the suggestion posted by unbuiltnautilus, and now everything is working as it should. To recap, I have swapped the TX from mode 2 to mode1 and changed the throttle to channel 3 and the rudder to channel 2. This means everything works as it did on mode2 without the motor going flat out in reverse for 10 sec. on start up.

Many thanks for all the help

Is it possible to automatically centralise the throttle control

[triumphjon]

install a spring return kit onto the throttle stick , think the kit is less than two pounds , ive now got two radios one which has all sticks with sprung neutral , for scale electric models , the other has twin ratched sticks which i operate my scale / racing sailing models .
