Now, it seems to me, that there is a need for basic advice for the "Novice" and that's me.

It's very daunting when you look at things like speed controllers, motors, servo's and the like, which voltage do I need, what speed do I need, is there a "Rule of Thumb" guide, if not, can we create some parameter's as a guide, probably a lot of folk will have conflicting ideas but that's OK.

What I don't want to do is buy bits, like I already have done, that I may never use, so your thoughts and ideas please chaps and chap-esses if we have any 2thumbsup

Battery and speed controller will depend on the motor you select you'll need the Voltage and current req'd for the motor these will tell you the minimum speed controller needed in Amps and whether your using a Brushed or Brushless motor.

OK I get that the voltage and all need to be matching but I'm not into this sort of stuff yet and am trying to learn, what would go with this motor please. Barrie suggested this one to me 2thumbsup

forgot to say, these are the [url=[url=https://s798.photobucket.com/user/rhode-island-red/media/Model boats general/SAM_1629_zps05804b56.jpg.html]What electrical bits do I choose ? SAM_1629_zps05804b56[/url]]Batteries[/url] I have for the "Fast Patrol Launch" and was hoping to use these and keep to one type if at all possible, six cells at 1.2v = 7.2v I presume.

hi,
i would use 15amp mtronix plug and play speed controller with 7.2 volt battery pack with 545 or 555 motor which barrie recommends as well from howes models or cornwall models your choice, all are good sellers.plus put 10amp fuse to prevent speed controller smokeing if to many amps . never had any problems with this set up. hope this helps  then as you learn more you can vary what you need. some times when you get a lot of weed round prop it will cause drag and raise the amps till fuse blows that's why it is safer to fit ,simple to change fuse 10p controller 20 pounds plus

I agree with David - Mtroniks ESC and 7.2 volt battery. An advantage of the Mtroniks ESC is that it provides the supply for the Receiver also - no separate receiver battery required.

If you look on the Component Shop website there are some typical wiring diagrams, although these use Action speed controllers which do NOT have the receiver battery supply.

Thanks chaps, the fuse is a good idea, hadn't thought of that, I think I have a plan now.

Mtroniks ESC and 7.2 volt battery it will be.

I hope this little bit of info that you have provided will be helpful to others in my position 2thumbsup

Where do I put the fuse chaps, before the speed controller battery side live or after speed controller on the motor ?

Here are some spade type fuse holders I bought from ebay

If you want to protect your ESC, between the motor and ESC. If you want to protect your battery, between the battery and the ESC...... or of course you could fit both Very Happy Laughing lol! lol! lol!
