    new question! Will a 7.2v Nimh pack (I think sub C size cells) fit instead of a lipo?? I ask cause I have 6800mAh one...

    Cheers Bruce

        To be slightly more specific, you have 6 and 3/8" inches of available space in the battery compartment. This info is based off of measuring my new SAS 3.5" cylinder that I recently received.
        IT TAKES GREAT INTELLIGENCE TO FAKE SUCH STUPIDITY!

            Bruce I run a wolfpack 7.2 4200ma Nimh dialed the throttle epa to 58 and I get more than plenty play time with my Skipjack. So a 6800 will give you hours plus of dive time. My experience is that a big battery like that means your weight to get level will be aft of cog. But I needed to add a bit of weight to my sd to get it to float level in the tub. So maybe the battery pack you have will negat that...

              Cheers Alec,

              I found a ebay seller in Hong Kong that sells em cheap ($23.32 and free postage) If its too heavy I can always use it in my Type23....

                The pump used for SAS is rated for 12v. Running it at 7.4 v will make it run slower, yes? What does the difference in voltage equal out to difference in bringing up the sub time wise?
                If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                  I run all my subs on 7.2 and the LPB pump I find works well on this voltage.

                    I believe it does run fine on 7.2v. I am just wondering the difference the 11v would make. There would be a performance difference, and I am wondering what that would be.

                      I have not measured the de-water time for 7.4 and 11.1-volts.

                        the ebay store for the cheap Nimh's is called "bestpricehere" from memory!! (so I may be wrong!) they sell all kinds of other stuff too...

                        Also something run on 7.2v that is rated for 12v will run cooler and last many times longer than if it is run at rated power level.

                          Had I thought last night while watching F1 qualifying on TV!! Is anyone (Dave.....) going to do a hull insert kit for a George Washington class SSBN???

                          Just a thought!!

                          Cheers Bruce

                            Not only no, but .... HELL NO!

                            The ONLY thing common to SKIPJACK and WASHINGTON class is hull form -- other than that, everything's different.

                              LOL Just poking the bear!! I'm sure there R experienced modellers out there already contemplating such a conversion!!

                              I am looking fwd to having my Skipjack in the water...hopefully having a crack at hunting my mate Rob's (From way over in Perth) giant 1/72 Typhoon at next year's annual regatta in Narracoorte (if he brings her over with his Kirov 'Peter the Great')

                              I think this was taken a few years back Not sure if its Rob's Typhoon there are 3 or 4 of em' getting about around Oz!! At 2.4m long these monsters are as long as Ticonderoga class cruiser and much wider!! I'm sure Slats will know who's Sub this is??
