Took other images and changed colour of light.

Now even I can see the marks Doug!

I expect you all could anyway......................

Thanks both for that.

Hope for a test before we leave on Friday.

Cheers

OK...................No more 'sorry' bit!
Going to start a new Topic re the Esc/Mixer multi controller.

Cheers both.

NPJ

STOP saying sorry!! 😡
There's no reason to be 👍😉

Thanks for that both.

I will check out the list here and if not already present, start a new one.

Sorry to be so slow on the up take.

Cheers.

If you want to ask a question the Forum is the correct place.
Your build blog is for describing your progress and may not be seen by all members who are not subscribed to your blog.

Or concentrate everything in the Build/Upgrade blog?

Neil
Start a new topic in this electrical related section of the forum

Yes me not being properly awake............it was transducers that I intended to write...............

Thanks for the info. I hope to run a test on the sound setup before going away.

Behind now due to weather, but trying to catch up.

Which is right thread to ask you about the ESC/Mixer set up?

Very glad you chaps are there.................!

All the best

Hi Neil,
I noticed that you've had a look at the extensive Electrical Blogs about wire thicknesses from a month or so back, so maybe you found the answer, if not-
Use flexible multi-strand wire with a cross section area of about 0.75 mm².
Don't get the +s and -s of the exciters mixed up or they will work 180° out of phase and dampen the volume.

BTW: the exciters are not transponders! Transponders are devices which respond to a particular input signal by sending a signal back. Such as the transponders in aircraft; they respond to secondary radar signals by sending back their ID and location, height etc. Or ship's SAR beacons which respond to a 9GHz search radar by sending back ID and location coordinates. The exciters are actually transducers which take an input signal in one form and convert into an output signal of a different form; e.g. here electrical to mechanical! Here endeth the lecture for today! 😉
Happy modding, Doug 😎

Doug.

What thickness of wire for the transponders/exciters please?

NPJ

Hi Chris, no you don't need 70A wire! 😊 That might be horribly thick and stiff for a scale boat.
You need wire the same size as probably on both your motor and battery. Same the 'standard' wiring in cars. Available I suppose at Halfords and any car diy shop.
WHAT YOU DO NEED IS A 15 OR 20 Amp FUSE TO PROTECT THE WIRING IF THE MOTOR STALLS (PROP GETS BLOCKED) 😡
If your ESC has a BEC supply for the RX put the fuse in the positive motor lead, probably red or yellow. if not, i.e. you have a separate battery supply, put the fuse in the positive lead from drive battery to ESC.
Then at least the RX will still work and maybe you can see from shore if it still responds; e.g. by switching on lights or some other visible function.
With twin or more props fusing the motor wire itself can sometimes help get the boat home on a remaining engine.
Somewhere in the Electrical stuff blog is a long discussion on the subject!
Have a look here

"What type of wire?"
Happy sailing 👍 Cheers Doug 😎
PS: Almost forgot, if you have a brushless motor you have no choice but to put the fuse in the positive wire from battery to ESC! Brushless ain't got no positive!
