Time to completely re do the Widowmaker!!

The epoxy came loose on that motor and the windings came loose. They started to drag on the rotor an it killed the motor. The stock motor isn't any more efficient than the HK motor anyways. They are both cheap 2 pole motors. The insides of both motors are almost identical. Same ratty looking windings in both, with probably a 60% efficiency rating, if that! It will be nice to get a good quality 4 or 6 pole motor soon.

Ok. No video today but I got a chance to get it wet. The boat is a completely different animal. Since more of the weight is shifted towards the rear it's on plane almost instantly after hitting the throttle. Gone is the "sway" when turning. No longer does it turn like a lifted F350! Its 100% more plated than before and it runs less wet than before. Conclusion? Success!!

I got a lot of negative remarks about my project mostly from people who had given up of stepped hulls. After researching lots of forums and reading a bit on the web on stepped hulls and hydrodynamics I came to realize that the spot where I put the motor is where boat designers who work with stepped hulls concluded that the CoG is on a stepped hull boat. That spot,"typically", is one step above the lowest part of the boat. In this case Proboat put it too high and over the first step of the hull. It's in the wrong spot according to what I have read and by the experience I have gained from rebuilding this boat.

The picure below is of the final layout which worked for me. Placing the motor on the hull lowered the CoG and placing most of the weight over the second step of the hull put most of the weight in the boat right where it needs to be. I'm happy with the outcome!!

The motor will be replaced with a B36-56-2600KV motor and a Turnigy 60A marine ESC that I ordered today.

Great news on the result! One thing i need to point out to you though...............You will most likely fry the 60a ESC on the first run with a 36-56 2600kv motor..............get a Turnigy 120 for 49 bucks.

Really?

The boat weighs next to nothing and is only 22" long. It comes stock with a 36-56-2900kv motor and a 45A ESC from Pro Boat. I figured running lower KV and higher amp rated ESC might cover it. I have read of people running a Turnigy 35A ESC with the stock 2 pole 2900kv motor with luck.

We'll see how long it lasts when it gets here.

Well............i did happen to forget it was a small boat, with a smallish prop it may work out....................sure hope it does! Its just that a 36-56 2600 can pull some big amps. Lets see some vid!

It has been raining here all day so I didn't get a chance to get to the pond long enough to take video. I'll try and get some video soon.

The 2600 is going in there with the stock prop which is pretty small. The boat will end up being my 9yo son's since he wants to get in to boating now. If the cheap HK motor pulls too much, and he likes it, I'll break down a get an Ammo 36-50-2300 and prop it up a bit if necessary. A 6 pole motor should be far better suited for the 60A ESC considering efficiency, no?

Looks good hope can't wait for the video!! I may rip mine apart if it works way better now!
