cheers for that bob, might have to as the ESC gets hot running 7.2volts through the motors even though im not using full throttle at all.

Jay

isnt it rated at 15 amps and fused at 15?

Bob

[J.beazley]

yep ESC is 15amps and still got the fuse in place at 15amps also.
might have to get her on a lake and test the pulling amps while in the water.

ESC has a temprature cut out anyway but they dont always work do they Bob

If you are concerned about the speed controller I have a spare mechanical one that you could use for trials with the 15 amp fuse.

thinking about it i have the mechanical one that you gave me with the boat 
will have to post a pic so you can tell me which wires go where.

Don't you two have each other's phone number yet?

Shipmate60, regarding the mechanical controller that you mentioned, would it be one of the old wire-wound types?
I'm searching for the type that resembles a heavy-duty wire that's wound on a former, approx. half-inch diameter. The wiper - which connects directly to a servo horn -  is normally at center position. Forward/Reverse and speed control is achieved by moving the wiper along the coil of wire to the right or left.

If this is the type you're refering to, would you consider a sell?

Jay:

Another question is ive got a normal car charger that will charge at 6v or 12volts and only puts out 6 amps (not that i would charge my SLA with it )

But why not?
Put it this way, do you have an alarm system in your house? You do? So have you ever wondered how the system remains on-line even when there is a mains outage? If you're really nosy, you'll kill the power to the alarm, disarm the anti-tamper loop, then take a butcher's inside the panel. See that black blob there?... that's the SLA battery. That's the baby which keeps the system running - even in the advent of said power outage. See that mains transformer there, also? That's the baby that maintains a constant trickle charge to the SLA. It's doing exactly the thing that bothers you about charging your SLA from a car charger... albeit at a smaller charging rate.

You said your charger "only puts out 6 amps". Bear in mind that 6A is a heck of a lot of current. But If you're that concerned, stick a low'ish-value, high-wattage resistor in series between your car charger and SLA first.

But before you go doing any irrepairable damage, a shot of common sense will tell you that shoving 6 amps up, say, a 3-amp SLA is asking for trouble if you leave it connected for longer than is healthy. Just apply the golden amps-per-hour rule. And don't feel guilty about your sudden impulse to buy me a crate of Strongbow.

PMK,
MFA still sell the wire resistance type mechanical speed controllers.

Bob

[OMK]

Why, thanks, Bob.
But can I pick your brains once again, pse?......

Could you tell me how I might contact MFA? Would you have their Web address, or email address?


Thanks in advance.

[J.beazley]

Pm sent to you PMK with all the details you need for MFA

hope this helps

They also come up quite frequently on eBay, and very cheap as no-one wants them anymore.

The forum no longer send me notifications of PMs or replies to the threads. It's only by chance of re-reading this page that I learnt of the last two replies.
Didn't mean to ignore anyone - simply unaware your replies were there.

Shipmate Bob: Thanks for the ebay info.

Jay: And thanks to you for the MFA details in your PM.
Although the URL does work, I still cannot find any reference to those mechanical speed controllers. Fact is, the page is pretty devoid of ANY information.
Might you have the URL which points directly to the page of said controllers?


Thanks once again.
