Hi Dave, sensible answer 👍
A Footnote ? Sparks are essentially broadband but most of the energy is in the HF & VHF bands and tails off significantly above the UHF band >500MHz. However, since the energy is proportional to the arc current(spark) and this rises with the applied voltage causing it your comments re fast electrics using higher voltages is entirely relevant. Also any close neighbours still using 27, 35 or 40 Megs will not be too chuffed, especially the fliers 🤔 Cheers Doug 😎

This thread has been a great help! Thank you all.

Regarding brushless motors, you must not add any capacitors across any of the three connectors.

The interference is caused by sparking between the commutator and brushes on a brushed motor, and brushless have neither.

I would tend to agree with AlanP regarding lack of interference from un-filtered brushed motors when using 2.4Ghz.

However if you are into fast electric then suppression is important as their motors can generate lots of RF noise and losing control of a fast craft is not to be recommended.

Whatever RC system is being used all signal wires must be routed well away from any motor high current wires.

It's good to see that we have members who have and share their knowledge and experiences.

Hi Alan all posts are worth mentioning or how else would we all learn😁

All my boats are now on 2.4 Ghz, six of these have brushed motors, none have suppressers, no problems over the past 4 years.
Just thought I would stick my oar in 😁

Alan

Thank you all for your help, pretty sure i will be back when i hit my next snag.

of course it is Ed us model boaters would be lost without this website wouldn't we

Hi George

I'm know expert, but I try.
And isn't the hobby about sharing and learning.
Got to pass it on...

Regards,
Ed

figtree7nts wow that's a brilliant description so easy to follow i thank you. you just taught me some thing new never stop learning cheers.

milklin2 you should have no problems with the step by step guide figtree7nts has provided you in this post

Hi Mikelin2

I must agree with Georgeo5664, follow his directions you can't go wrong. you must solder the capacitors like he has described.
The capacitors will help with any interference made by the motor(S)
Take your time and look at the picture.
You need to use capacitors that are the right ratings.
lets say 2 capacitor at 0.1uF and one at 0.047uF now slide the 0.047uF capacitor through both terminals on the motor, slide the ends of the 0.1uF capacitors onto the opposite end of the motor terminal. now solder the terminals with solder.
Take the ends of both 0.1uF capacitors and solder them to the case of the motor. Make sure you grind down a bit of the case. so that when you solder the capacitors to the case they stick to the case.

Don't forget to solder on the leads, that go to your motor(S).

Now as to the question about do you need the capacitors
I would use them know matter what, just in case.
But I've been told that if your using a radio that's on 2.4Ghz,
You don't need any capacitors...

I hope this helps

But, in the event that you still don't get it, I would try to become a member to one of the local RC model clubs near you.
And see if someone can help you with your motor.

NOTE:
Please use this information for a Brushed motor Only!

Brill thanks a lot i now understand.
😜

mike yes suppressors are required it helps to cut down the interference from the tx 1 capacitor goes from + to casing 1 capacitor goes from - to casing and last one goes from the + to the - pins on the motor hope this helps

Ed
many thanks, i must be a bit thick i still dont get it. i have enclosed a photo of motor any help would be appreciated. I would also ask are surppresors required at all.
mike

Hi Mikelin2

Take a look at the ALL THINGS RC area.
then look in the (Motors) Suppression area, there you will see where to solder the suppressors on to the motor.
Hope this helps.
