Brushless Boat Question

I don't think any of the RTRs will take 2-4s packs in series, as most of the cheaper ESCs only go up to 6s Max, and 2x 4s packs in series is of course 8s.

The PB impulse will take lots of 4s2p 10,000mAh setups just fine, but a few of the taller cells may not fit under the subhatch, and necessitate you running without it. 10,000mAh should get you 10 mins on the stock prop or a similar sized metal one.

The Tenshock will not take 2s2p 10,000mAh or 4s 5,000mAh and as such you would have to prop down to get 10 minutes runtime and as such the impulse would be considerably faster if they were both setup for 10 minutes.

I am sure the Impulse can be made to self-right with a flood chamber on 4s1p but am not sure you have room for the chamber and offset weight with 4s2p in it, as few folks here run 2p and few folk in the states run self-righting monos for some reason (in Europe they all are) I know its ugly but I would try strapping a big (empty) plastic coke bottle to the top and seeing if that will flip it over in the bath, if it does then strap it on for your first few runs untill you learn what waves you can take at what speed in what direction, then you have a much better chance of getting back to shore upright when you take it off.

Nitrostarter is right about the fishing pole, I use a cheap childrens telescopic fishing rod, with a tennis ball on it for rescue when I'm boating alone (there's rescue boats at all the races), though I keeep thinking of but never get round to upgrading the tennis ball to something a little smaller, as when wet its pretty darned heavy and makes the last section of the rod bend a worrying amount, and it doesnt half make a loud thump when you score a direct hit, which is quite scary though i have seen no signs of damage from it yet. You dont need an amazingly strong line as your not trying to pick the boat up, just drify it in and it takes very little force but having the last couple of meters/yards made from plastic coated stainless "pike wire" (do you have pike over there? if not its 20-30lb metal line for use with fish that have teeth) is a good idea as I learned early on when i cast over the boat, started reeling in and then it got strangely easy, strange that is till I saw the tennis ball floating away, it had wrapped round the sharp rudder and cut itself free. I got both boat and ball back about 15 minutes later as I was standing on the bank with the wind blowing towards me, which is another top tip.

If your ESC has a programmable cutoff, set the voltage nice and high so you still have some left to get you back to the bank when it hits, timing the run helps too, if you have a stopwatch/digital watch/egg timer/friend/clever TX, as then you will only ever have to hit the LVC once, then time your runs so you come in earlier.
