    Mornin' Martin,
    Pure curiosity! Which motor is it?
    Re LiPos, recommendation difficultπŸ€”
    Different Brand names seem to prevale in UK and Germany, unless the ubiquitous Turnigy!
    Whatever the brand and wherever the shop is you buy from they nearly all seem to be manufactured in southern China, Shenzhen mostly!
    ( I have kit for a Shenzhen class modern destroyer of the PLA Navy!)

    The price for the Overlanders looks good, and if the shop values it's reputation they will be good, and they're nearby if the wheel falls offπŸ‘
    Cheers, Doug😎
    PS Your 'stuff' should be on it's way tomorrow. Weather cooled down 15Β° or more, currently 18Β° and drizzly rain with occasional short sharp downpours all day today - one extreme to the other! Mail coming today re 'Brass Bashing' etc.

    Ah, that explains that then, Thanks. I got the motor yesterday. it looks a very nicely made thing. I'll finish the boat and then think about ESCs and batteries. Do you have any recommendations for makes of LiPos? My local shop does 2 and 3S Overlanders for around the 15 quid mark.

    Cheers,
    Martin

    Hi Martin,
    The card starts at 4S because the ESCs recognise 2S and 3S themselves.
    You only have to tell 'em if you are using bigger batteries.
    BUT: looking at the manuals I see a whole load of other 'stuff' for the flyboys which is useless for boaters and would need to be switched offπŸ€”
    e.g. 'Flywheel', 'Governor'. To change some of these functions you apparently need an 'extension cable' which only further complicates the issue 😑
    Sooo! Stick with the deal you found at the start of this thread and just switch off the 'Brake' function. This easy to do. You only have to select the Mode 'Forward/Reverse' or 'No Brake'. The ESC will normally be delivered in Mode 'Forward/Brake/Reverse'. I have done this with all my 'Car' ESCs only takes a few seconds😊
    Cheers, Doug 😎

    I notice that card thing has cell numbers starting at 4. I will never use more than 2 or 3S. Does that make it unusable? All the rest means nothing to me at all!

    I was looking at that one!
    But as for the programming card...Gawd knows. I wouldn't know where to begin!
    Right now I'm bloody panicking as I can't find the Supermarine motor for the Crash Tender! I thought it was in the old motor drawer, but it ain't. I'm crossing fingers it's in a box in the loft. My son-in-law will have to go up there when the weather cools. Even he doesn't deserve the temperatures up there!

    Got my watt meter today, so that's now in a box with the condition meter and multi-meter, oh and the chenglish Charger and its power pack. BL motor and CNC 32mm prop still on the slow boat. So the ESC will be the last of the clobber for a while. By the time I have it all together it'll be Winter and all put away again!

    Thanks again, Doug.

    Cheers,
    Martin

    Or this one
    https://hobbyking.com/en_us/hobbyking-yep-60a-2-6s-sbec-brus...
    and it has
    Blocked rotation protection (senses a jammed motor and stops motor rotation) πŸ‘
    Get one of these to go with it so you can get the best out of the ESC and motor

    Ciao, Doug
    BTW: Some stuff might be out of stock at the UK warehouse but still available at the EU warehouse in Holland. You'll get the stuff just as quick from them and still duty free - until BREXIT πŸ€”

    Hi Martin,
    this one's in stock, and in the UK warehouse! 😊

    Hi Doug, thanks for that, but I've just seen that every bloody one is out of stock! I figured it worth spending a little more on a Turnigy. Unfortunately so, clearly, have a lot of others. I'll see if they're available from others.

    I checked the 152VO site and most use a Turnigy 60 A it seems and I assume are well pleased with them.

    Thanks for the clarity about testing though, Doug. it's good to hear what one guesses at being confirmed by an expert.

    Cheers,
    Martin

    Hi Martin,
    there's a good selection here. I selected the 'Plane' filter, LHS of the page.
    https://hobbyking.com/en_us/power-systems/speed-controllers/... href='https://model-boats.com/search?q=tag:brushless' onclick="loadpage('search?q=tag:brushless'); return false;" class="taghighlight">brushless-esc.html?___store=en_us&dir=desc&esc_compatibility_type=4564&order=price
    If you want high current you're gonna have to dig low in your pocket!!😲
    Same page in pounds
    https://hobbyking.com/en_us/power-systems/speed-controllers/... href='https://model-boats.com/search?q=tag:brushless' onclick="loadpage('search?q=tag:brushless'); return false;" class="taghighlight">brushless-esc.html?___store=en_us&dir=desc&esc_compatibility_type=4564&order=price
    Choose one about 80A+ with 'jammed motor protection' !!
    This one perhaps
    https://hobbyking.com/en_us/yep-80a-2-6s-sbec-brushless-speed-controller.html?___store=en_us
    That's the snag with brushless , without the 'lecktrickery' they're just paperweights! Check the motor specs very carefully for current at max efficiency and MAX current. For testing 'unknown' motors get a 100A+ ESC. Put the ubiquitous 'Wattmeter' between the battery and the ESC to measure actual current drawn. Have fun, don't burn ya fingers😑
    Cheers, Doug 😎

    Oddly there's only one page of them and most are low Amperages. Maybe that one above is a good idea after all. I'm wondering how you can tell the amps of a motor if you don't have an ESC to run it with! And if you just buy anything to use, what amps should you get?
    What governs the amps on a brushless set-up? Most use between 45A and 60A on the outboard boats.

    Martin
