    That is all we need. All three of us standing there, one covering his mouth, one covering his ears and the last one covering his eyes. LOL I will do some research on a ESC. Any suggestions? I will now have an extra ESC for the other boats. I have to say, for $48 it has done very well.

    For just to test now may be you can get the HV240a Damen has,
    Most people use that 200a esc you have for 4s setups,
    And 5s tops depending on the setups and boat.
    So you where using that esc in that boat before on 6s with the stock motor ?
    Or the stock 120a and than the 180a upgraded one ?
    ? ONLY IF THEY WORK

    After the original 120a popped, I replaced it with the 200a. The 120a popped on the second time out. The 200a has about two hours of run time on it, without a glitch with the 6s setup. From day one, I have been using a 6s setup. I was using the stock motor but did replace the prop to the next size up.

    They did not send you a upgraded 180a for the one 120a that popped under warranty ?

    Is the magic number 30,000 for this style boat? Speaking to someone and they are suggesting a 730kv with the 6s. I am thinking that would be to low in the RPM's. I calculated the numbers and 8s with a 1090kv came in just over 30,000.

    No 730kv on 6s would be a tug boat,
    Hears some numbers to look at.
    The stock motor was the V700 1100kv and on 6s*1100kv=27720.RPM

    6s*730kv=18396. 7s*730kv=21462. 8s*730kv=24528. 9s*730kv=27594. 10s*730kv=30660. 11s*730kv=33726.

    12s*730kv=36500.

    6s*1090kv=27468. 7s*1090kv=32046. 8s*1090kv=36624. 9s*1090kv=41202. 10s*1090KV=45780.


    Sorry I was tired last night and did not remember to add full voltages to the numbers,
    It is up to date now.

    12s*730kv=32412.

    6s*1090kv=24198. 7s*1090kv=28231. 8s*1090kv=32264. 9s*1090kv=36297. 10s*1090KV=41420.
    The same numbers I have on the tool box. I think I am going to stay with the 8s - 1090kv. From the stock setup to this will be over 10,000 rpm's. That is a huge difference. Thank you for the numbers.
    Did not know if there was a magic number with this size boat. I think I will be very happy. I just need to charge the new batteries and go. I installed the last piece yesterday which was the water line. I may balance it today at the 30% position and mark the inside where the batteries need to go. The way I did it for the first time when I bought the boat worked out very well, either I was lucky or it was right on the money.

    Not only will I reply, I will have video. I use a GoPro strapped to my hat and there is usually someone that will use a video camera.
    My thought on this is that it will either run like a raped ape or be a dud. LOL
    As Lenny posted with the rpm of the combo, I think I will have white knuckles.

    I have heard some negative stories about this motor. I thought about buying this motor until I started asking around on the message boards. The one thing everyone said was that it will not last long, the second thing was that it did not compare to an equivalent sized motor. I would do some research first. I spent a little extra and went with the Leopard. Not that I am trying to sell you anything, I do have a new Leopard 5692 - 730kv. I went with a 1090kv for my battery size.
    Good Luck

    You may want to try looking into running one of these 800kv motors in it,
    Not sure if fastVee or Ray has any up dates about them or if anybody has done any testing with them yet.

    All completed. The new ESC is installed. One set back was that I had to use a receiver pack. Took me about an hour to figure this out. I thought I had a problem with the ESC. The only pack I had laying around was a 3,000. I thought I had a smaller one. I will look this week. As of now, I am looking at Thursday to go out and see what will happen.

    What esc is that in the boat setup ?
    http://www.offshoreelectrics.com/pro...-seaking-130HV
    If it is the SK130a HV with 180a burst you better keep it propped down,
    Till you know what amps you are pulling with that motor.
    Because that motor will pull some high amps though that setup if you over prop it.
    And are you going to be testing this setup on 8s to 10s ?

    I went out today. It was low 60's here in south central NJ. Unlikely that we will see that again till spring. The Atomik had a glitch on the first pass. The water feed line came off going to the water jacket. The boat filled up with some water. Brought it in, fixed the line, topped off the batteries, watched Ken fly around with his Genesis.
    Reset the GPS, secure everything and try it again. Off the work bench into the water the boat appeared to be on the money. I was using two 4s 6000, 25~50c Turnigy Nano Tech batteries. I know they are under in the C rating. Surprised after a 3 to 4 minute full burst straight away runs, the batteries were at 85 degrees, the motor was at 90 and the ESC was at 88 degrees.
    With the GPS tuning off but recording the max speed before turning off due to low battery, I recorded a max speed of 59.3mph. I was a very smooth ride. Ken did the video and Damen did the still photos. When I receive them, I will post.
    All in all, I am happy. No tweaking was done today. I just enjoyed it. I will now tweak it a little to see if I can hit the magic number that we think it can hit (70mph).
    I did roll it, which landed right side up. I think after the first roll - the battery tray separated. The boat was leaning when accelerating from a stop. After moving it would level out. The problem was when I would release the throttle the boat get loose. The boat rolled two more times - always landing right side up. No other damage or problems to report.
    I did use the data recorder. I will check that tomorrow.

    Ok hey you guys, It has been two weeks now.

    So what the hell happen ?

    Do you need a flash light and a mirror to look for the data, pictures, video's that Damen & Ken have ?

    I was just thinking that you could get some better vids of all your stuff,
    If you rigged it to you tx and followed all the action in the foreground instead of trying to say in front of the cam.

    I shoot all my vids like this now when I need to,
    Just aim the tx like a gun at the boat or what ever you are running.
    It takes a little time to learn but works pretty good,
    I still need to learn how to follow and zoom and drive at the same time with out screwing up the run.
