Finding a balance point & balancing a boat .....
After reoutfitting my mean machine with a 3656/m442 and posting this 2nd video after a strut adjustment, I still had work to do. As pointed out by flraptor she was running wet (too nose heavy) which also cost on speed. She was also pulling to the left but that's just a rudder adjustment....
I got my cooling sleeve in today for my 3674 (2350kv) so I went back to work on it for another go round. Here is how I find my balance point on this hull. Everyone has a little bit different idea on how to do it but this works for me. I just thought some people might find this useful since I don't recall seeing an actual thread on how to balance a hull.
Start by outfitting your boat just as it would be as if it were in the water with the batteries, floation foam, hatch and everything else in it that you need to run. Then find out where your starting point should be. Then get a wooden dowel or in this case a broomstick and find your balance point as if it were a teeter totter.
I use a measuring tape to break this hull up into percentages ie: 25%, 50%, 75% & 100%. In this case this hull is 29" long, so from front to back 25% is 7.25", 50% is 14.50", 75% is 21.75" & 100% is 29".. I can subdivide the percentages from there.
With this stepped Hull, I want to start with a 70/30 split front to rear, so the balance point is on the last two steps when its on plane. This is pretty close to start with.
I pulled the 3656 & bolted in the 3674 (2350kv) and swapped in an m445 prop too. I fixed the rudder and slid the lipos back a few inches. Here's the layout.
Here's the battery placement if your wondering, from the sponson tip.
If I have time after Easter services tomorrow, maybe I can test her out & see how she runs now. If you have any tips on how you balance boats, chime in, I'm sure a lot of the new guys that have showed up here recently would appreciate it. Thanks :

Glad to see it being put to use instead of sitting in a box.
. It's a 60A ESC; but the motor to ESC is 5.5mm, the ESC to series connector is also 5.5mm connectors. The only deans plugs is the series connector itself. Its just a sportboat, but I have an anchor for the front of the motor & some 40c packs for it. I posted this real early this morning b4 bed, I was too pooped to set them up too......
