Cat Build(Here kitty kitty kitty)

[Eodman]

The instruction sheet that comes with the EP1 has a few suggestions on hopping them up! So I'll see after the Kitty is running!

[Eodman]

Well the Cat is painted, some of the hardware is mounted --- ready to go to the print shop so the graphics can be done!

Once the graphics are done just have to hang the motors, put the electrics in, charge the batteries and see if thing will go!

I'm pretty sure there will be a lot of tweaking to do! We'll just have to see!

Now do you guys know the bad thing about this build! Yup it was supposed to be done this winter! Now I have to find something else to build!

Now I wonder ........

[Darin Jordan]

In your research, have you discovered whether or not the EP-1s can be run in the right-hand direction?? I'd like to counter-rotate mine, but haven't had time to sit down and figure out if the gears in there would work in the opposite direction....

Oh, and by the way.... WHERE are the updated PICS!!

[SJFE]

Darin I have been in there. The gears will spin in either direction.

[Eodman]

Darrin, no I haven't found out yet .... but you know I'm using a Traxxas evx updated version Part # 3020! When you look at the parts listing for the traxxas villian they don't list seperate part #s for the 2 motors so where & how is the counter rotation handled? Could it be in the esc or wiring from esc? I'm not great with electricity so I need help here!

More pictures coming - hull & cover painted white, windsheild & air intakes painted black!

reverse the polarity of the motor

[Eodman]

Ok here are some updated pics of the hull painted --- should have the hull back from the print shop Thursday or Friday!

I also reposted a picture of my inspiration for the graphics ... my father in law worked for Jaguar & Group 44!

[Eodman]

Well the Cat got wet today & she didn't like it! I had the motors jacked out away from the transom and too much hull in the water so all it did was go around in a tight circle!

I looked for the allen wrench set & discovered that It was sitting on the bench in the garage! Couldn't adjust the angle of the outboards, so the first test ended early!

But it wasn't a total loss we picked up a second supervee on ebay so my son & I had some drive time with the 2 Vee's!

I forget... Are your motors counter rotating?Oh yeah brushed! NM that... That Is very Important for performance on twin motors.

[Eodman]

They are counter rotating & I'm sure I had the batteries to far forward but there's a learning curve here! So I'll make some adjustments and try again! I'm using the stock props(plastic) so the weight may be to much for the Plastic props! I'll order some metal octura's just slightly more agressive in pitch & diameter this week!

I just bought a new charger & it'll will do Lipos so if its the weight I may start upgrading some of my batteries!

Growing up we had an 18 ft Sidewinder with a 135 Evinrude on the tailend and I would play with the ride height of the motor and found the same thing but also would experience porposing at the higher heights!

But I don't want to change the motors until I at least have forward momentum of some sort!

[Stealth Assassin]

IMHO... Reversing the polarity on a brushed motor Is tough to get It to match the other because of the timing = the one reversed slower than the other.

IMHO... Porposing comes when you reach a max hp and the hull does not pull forward anymore. Also more minor cog... But, what do I know!

[Eodman]

I'll double check but I tought both were at 0 degrees timing!

[Eodman]

Well don't I feel like an idiot ---- can we all say a**hole! Guess what I neglected to do? Yup that's right I never got a counter rotating prop no wonder she didn't like the water!!!!!

I guess I better send an email to Steven asking for his help in selecting the right props!!!!

Damn do I feel stupid!

[Eodman]

graphics

Well here's a couple of pictures of the cat with her graphics! I think it looks good -- now to figure what props to put on her!

Looks nice...

Reverse rotation props that will fit this outboard are limited... but here's what I'm going to do...

First, if you trim the water pickup tube you can fit a bigger prop... I cut mine right back up to the cavitation plate, leaving it at about a 45-degree angle, with the lower end of that angle stopping right at the cav-plate...

This will allow you to fit about a 36mm prop with no problem...

Because the shaft is 3mm (whoever decided this was a good idea should have their head examined...), a prop with a 1/8" ID is going to be slightly too large...
but it's close enough... You can get an X430 in right hand rotation, but I personally think the prop is too small...

Graupner makes several in reverse-rotation, and OSE sells them... I am going to take the 4mm shaft size Graupner 36mm prop and modify it to fit by sanding down the cone and drilling the hole all the way through... I've done this in the past with decent results... You can get that prop in both right and left rotation, so it would be a good pair...
