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 !

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

[Brushless55]

twin bigs!

[BILL OXIDEAN]

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,

No cooling jackets on those 540's?

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

[BILL OXIDEAN]

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..

[BILL OXIDEAN]

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

[BILL OXIDEAN]

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

[BILL OXIDEAN]

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??

[BILL OXIDEAN]

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.

My first tug was gonna be with some 50c 5200 2s packs one for each side..

Bill, you staying with the stock cables? I have better ones and better couplers to hold the power.

[BILL OXIDEAN]

Bill, you staying with the stock cables? I have better ones and better couplers to hold the power.

I was gonna' PM you about that..
I just went into the strut because it had a failed bearing.

I upgraded to some Boca Bearings, and got to thinking about the cables, and couplers.
I will definitely be using you..

Wait, that didn't come out right, I'm sure you don't appreciate being "used"

I'm gonna need some rather short 5mm to 130 aluminum couplers. If you machine 'em especially for the king of shaves, I suggest tapering the motor end to accomidate the output hole in the motor mount. That way it can recess deeper for more support and truer running

[BILL OXIDEAN]

Well, I got 'em in.. 2 Novak HV motors. They're different winds otherwise I'd be runnin' 'em tomorrow.
new style adjustable timing HV motors coming soon..

It feels great to have the opportunity for you guys to see how I go about things. This boat is different like me, and I feel we're a fun combo lol!!
I feel good about the glassed in steel motor mount anchor idea. It could eliminate the need for a front support guilatine on longer motors.

[Jeff Wohlt]

I was used for 15 years but she is gone now...LOL

Yes I make them to fit the length they need. Sure I can taper them at that end but never have yet.

[BILL OXIDEAN]

The best way to describe a king of shaves is someone took a gamma ray and shrunk the real boat down to 1/16 scale. Never have I seen a boat with so much detail especially rtr.
Its a concourse winner out of the box

I'm not a product "fluffer" just a serious appreciator of quality models. Anyone who owns one or has really taken a look at the thing would agree..

[Jeff Wohlt]

Bill...pm me a measurement of the space from the motor to the stuffing tube...I may have a better idea for you for a coupler. How long is that motor shaft sticking out ?

Will do..

[BILL OXIDEAN]

Ok boys, Airtronics wanted me to try a hot new servo in their 2010 line.
Its a low profile job with GOBS of torque for its size, remarkable speed and pinpoint accuracy.

Venom radios are excellent but we will be upgrading this boat to all Airtronics plugs, wiring, and componnents

[BILL OXIDEAN]

I'm now back from Kauai and have been notified that a box comes from Novak today!
Let's see what we've got, we may be running her soon!!

[forescott]

I thought I would post some speed results on my ekos. I ran it today on a new pair of turnigy 5000mah 35-45c 3s lipos. I was replacing my venom 5400mah 20c lipos I originally purchased with the boat. I wanted to run 3s instead of 4s to test out my new cooling and get a little more run-time with less heat. Still using my CF-40's I got her up to 46.2 mph on garmin gps! I thought this was very fast for 3s considering I only got 36mph previously on my ammo 2700's with the same props and old venom packs!

[C-Mac]

Nice results forescott. what model of garmin are you using?

[forescott]

I use the forerunner 101. I like its small size/low weight

[BILL OXIDEAN]

Thanx for the update Forescott! Yes that IS fast for 3s.
How was the torque? did it launch "snappier', did it hold its speed in the corners?

[BILL OXIDEAN]

Ok boys, back to the project at hand, what I've done here is a procedure I call "carpeting"

After removing the battery tray, and all of its epoxy residue, i wiped the glass center pod down with solvent to get a clean mating surface, then carpeted the whole belly pan with velcro.

I like going this route at first to give me versatility in component placement for CG.
