Upgrade motors for King of Shaves

[BILL OXIDEAN]

Good morning fellas, I've decided to join in on the fun. I'm doing a big block upgrade on this boat, I've already machined the motor mounts to accept 540 big bolt pattern.

This upgrade will take a few weeks as I'm waiting for the motors to come from Novak I just ordered yesterday

I will be gutting all electronics as far as radio gear, servo, wire harness etc.
I ran a bone stock one at the saws and trapped her at 50mph.

I like the way this hull runs and not only do I disagree that its scale geometry isnt good for a model, but I believe in the right hands this hull can hit 70plus

My first setup will incorperate 2 Novak 4.5 HV systems..
I will try the 32mm props then see where the 36mm props get me.

My first setup willl not incorperate counter rotating props.

I cannot wait to see the video of your Novak EKOS !

Couldn't help it

Ok fellas, I'm gonna' start this upgrade thread..

1) after removing the motor and speedo on both sides, I bent the mount forward to expose the 2 screws that fasten the aluminum mount to the steel anchor which is glassed in.

2) I marked the 540 hole pattern in the mount I simply widened the existing hole by approx 3/16 without making it any longer vertically

3) with a dremel, I clamped it in a vice and went to work

4) I matched up the 540 and used a large conical washer on the stock motor mount screws and voila, she's ready to bolt back in the hull

twin bigs!

Well boys, the motor fits, and an octura flex hex fits almost perfectly.
So far, it looks like the boat itself can be converted to accept the big bolt pattern and motors for around 16bux! (the price of the couplers)

Bill's boat is going to FLY!!!

Bill,

No cooling jackets on those 540's?

Bill,

Indeed they will be jacketed, the one pictured was for setup purposes.
I'll be using the new Novak 4.5hv with adjustable timing and removable stator
I'll probably go with ETTI jackets

They're actually 550 bl motors http://www.teamnovak.com/products/br...550/index.html

I went ahead and upgraded the screws on the motor mount to 3.0 x 6mm countersunk machine screws (hex head) Dubro pn #2285.
The philips head screws were difficult to gain leverage on, and to eliminate the need for maintinence i went with Zap thread lock and cinched them down very snug.

That's one area of vibration that's not easily accessible..

I had to do it..
I got rid of the gorgeous battery tray to open setup options. I chisled the excess epoxy off the belly pan with an exacto it actually came out clean

heart of glass

I was a bit rough with the mounts and will need to re-glass them in for peace of mind.
Here is where I have cut the cloth and sized it to fit.

I went with great planes fiberglass tape heavy (25mm) and will be using 30 minute epoxy

Impregnate

Ok Gents, I impregnated the cloth with epoxy, then carpeted them in with this epoxy brush..

I saturated the areas around the steel mount with resin to get a solid bond..

Are those motors 4800kv??

Really close sir, 5,000kv. I've been advised to run either the GTB or kinetic ESC.
Novak has machined an optional marine heat sink for its new kinetic speedo.

I'll be running it on 2s per leg..

What kind of battery setup are you thinkin? I have the 380-9xls in my e.k.o.s. but have always wanted to upgrade to 540's.
