    Just weighted the DF Sniper I am using with Seaking 90 water cooled ESC and the larger inrunner motor I referenced. Weight is 1 lb 14.5 oz without the LiPo pac. BUT, that weight also includes the GoPro HD camera mount screwed into the back of the top cowl. Add the lipo pac and you have the total system weight. I do not have a raw hull to weigh. So, less than two lbs RTR, NOT the set up I am running.

    It just seems off to me???

    You might get more speed & less amps from a smaller, metal prop.

    Ray, Have you upgraded to the HobbyKing motor you recommended? I removed it and back to the inrunner with again good performance. I found that the HK motors that were recommended in this forum were a bit too small after testing them. And you?

    That boat would be PERFECTLY matched with a car system
    Namingly Novak.

    I'm gonna; get one, slap it in, and show the word what's up..

    Little skinny 380 motors and airplane super low kv outrunners are a waste of time.

    540 diameter is right for this boat.

    A novak 4.5 ballistic system on a 430 prop would rip like a chainsaw on 2s lipo.
    9,000 kv with a dynamic timing advance, unstoppable in the thing..

    Frankly I'm still waiting for a HK motor for it.

    I really think a smaller prop on 2S and the 4400kv outrunner would go nicely but, I'm speculating> I would run 2S2p for that also (3200Mah total).

    Sorry, just been really cold out and my buddies haven't given me enough notice to go out & try it out. I don't go out alone in my wheelchair, to hard for me to launch and retrieve boats.

    I might just take that advice as I have been pondering such ideas...

    Just not Novak for me, don't like the price. I can get a high kv 540motor anywhere.

    First I'll try it stock, whenever that is .....

    s.
    Why not just run 4000+ mah 1p?
    On smaller boats like this a hard case car pack is perfect.

    2 x 1600 is what I have on hand.

    This system will get you 50+mph on 2s

    http://cgi.ebay.com/Novak-Havoc-Pro-...#ht_1431wt_907

    Less than 200 bux plus the motor is of high value bacause to change winds you only buy a 30 dollar stator

    If you bolt this in, you will be telling a friend Lol..

    Here's what it will do for you..

    That ESC is rated at 540 amps!!!
    And the suggested operating temp of the motor is 160 degrees!
    WOW!!!!!!!!!!!!
    If that's true, it is one badass setup!

    Their amp rating system is much different than what is typically used in boats, its capable of about 150-200 continuous

    The motor hits optimum power band at about 160

    That is awesome. No need for cooling really. Runtime with a 10,000 kv motor would be strictly SAW type though.
    There are a few different options too. Price is actually quite good.

    I've been able to get away with it running zero cooling on the motor in a 5-lap heat race! I now cool the speedo

    The 5000kv setup for 3s is even cheaper: http://cgi.ebay.com/NEW-Novak-Havoc-...item4cf33443f2

    Using the fan, or water cooling?

    I was using the fan on the speedo but now i've drilled out the heatsink and run water plus the fan and it works sweet!

    it wont let me post a pic for some reason though.
    Yes, the 3s setup is reasonably priced and will fly..

    Drop a 380XL motor in there and hang on. Depending on the kv, you would probably need a new esc aslo.

    I'm thinking a 540 size motor. Maybe a 380XL like Steve suggested. These things look to handle fantastic once properly trimmed.
