    I happen to have some free time for now. I’ll see if I can get some Etti 120’s sent out quick unless anyone has experience with the YEP HV 120’s?

    I just beat myself up till I get it back and start the mending/improving. Then it’s back to a challenge. What amazes me though is electrolysis. Man it shows itself under water. That was just 30hrs.

    So I got this fix for rudder rod boots figured. First a 5/16” end Mill on the drill press



    Then an old trick of putting a piece of brass tube inside the boot end before pulling it Thru the 5/16 hole. This is tricky but it works.

    Hi Shawn
    I have a YEP HV 180 and 120 esc's. It took me ages to figure out the programming as the program card has two levels of programs. You have to read through the program card instructions to learn this as it is not mentioned in the esc programming instructions.
    The only issue I have had with the 180 (I haven't used the 120 yet) is the start up speed. Because they are a watercooled plane/heli esc the start up is quite slow, even when programmed at max. It is ok in a mono, likely be alright in a cat, but no good for a hydro that needs a punch on the throttle to get it up out of the water. Otherwise they work ok and have a anti-spark built in which is quite good with HV.
    Did you consider the Seaking 130 HV esc?

    Thanks for that Peter. So they are opposite of an Etti then. Which is hard to get a smooth takeoff with. Although on this last setup I set to slow start and it wasn’t too bad. I had heard good things about the YEP’s awhile back and read up on RCG last night before placing my order. $110 a piece helps take the sting out of the mishap. And I hadn’t seen the anti spark thing, that is cool. I think I had read these had the ‘active freewheeling’ too some time back, we shall see.

    BTW, batteries are coming along, two 4s packs charged and half of a 6. Not sure on the internal resistance now tho. But it’s worth a go.

    Ok I got the YEP’s here and hey!!!, I can fit these where I originally wanted the ESC’s. I will put a couple standoffs down to hold the ESC’s up 1/4” off the tunnel floor. They will get a good waterproof job as well as per Peter’s advice. I need to wait for the programmer to arrive from China, ESC’s were in US but no programmer. Damn!

    Here is what I’ll be after:

    Allright, so some water testing of foam and I’ve determined that this is plenty of foam to hold this boat up: I may add a chunk to the lid for that ‘just in case’ feeling

    Foam is on my list of things to do for my current build. Any notion I had of just getting a few quick test passes in before doing so are out the window now!

    No doubt, this one stung a bit. I had like 3 of my ‘I should have’ going thru my head!
    #1: I shouldn’t have run without foam
    #2: I shouldn’t have run after the flip
    #3: I should have just taken the kayak out to retrieve(that is the costly one).

    Oh well if it wasn’t for ‘the hard way’ I wouldn’t know half of what I do! Haha
