Cat Build(Here kitty kitty kitty)

[Eodman]

OK found the specs on the Spektrum servos

1.) Z270 49 oz/in @ 6.0V all plastic gears

2.) Z590 85 oz/in @ 6.0V all brass gears including spline

So I have 2 of each but I because of the amount of weight hanging off the boat I'm going to use the Z590's!

Thanks for the help Guys -- maybe I should list all you guys on the boat as builders!

Excellent... Sounds like you are on your way...

We're all just paying it forward... someone at sometime answered our questions and gave us advice... Just passing it along!

[Eodman]

Well here's the new mock up!

I don't want to go any farther until i re hang the motors and see the size of the boots for the rods! But I think this will be better now where the h*&ll are those parts! Oh Mr UPS man where art thou?????

[Eyekandyboats]

That looks great
very nice!

[FE_Chris]

I dig this....I wanna see how it goes once out on the water!!!! NICE!

[Eodman]

Well guys USPS man delivered my stuff to my home & not to my office! So I have the ESC and I even have the gecko 101( not mandatory) but it will help offset some of the weight!

I'm really trying hard not to have to add lead to keep the nose down! Although if I go to Lipo's down the road I may still have to add weight!

The autobailer is here to so this week end I can do a little building & maybe a float test!

[Eodman]

Ok Folks --- Here's another picture of the Kitty build!

As you can see ... most everything is in the hull - just placed & guess what, put it on a round rod and it's close to being at its CG!

I still need the harness for the two servos, couple of other small parts but I think I can start assembly this week-end!

The part I hate is taking it back apart for final paint and clear topcoats, then out to the graphics shop for lettering and stuff!( I may be inclined to give it a short test spin before dis-assembly!)

[Darin Jordan]

Good Job, Eodman... I'm excited for you to get that on the water!

Can we count on some video footage???

[Eodman]

I can tell you pictures will be posted ---for video I have to get my son to show me how to transfer & post!

I got the "Y " harness for the servos today now i just to stop & pick-up female connectors for evx to motor & some more deans connectors!

Apparently, there are 2 schools of thought on outboard placement:

1 school is mounted close together, the other is out on each sponson!

Now this is my first build and not for racing so I elected to go close together!

When I was young(late 50's early 60's)we had a summer home on a lake in Sullivan County NY & there were actually 2 cats on the lake that had dual Mercury's on the backends and they were close together..... so drawingn early life input I elected to go close together!

If it doesn't work I can always change it!

I can say with experience with my own full scale cats Is, You want your drives to be behind the sponsons to protect them from getting the lower unit knocked off or broke then resulting Into a hook/barrel roll. Also It helps with drag and tourqe/pressure or force on the lower. IMHO...
Are the motors counter rotating Inwards? It will drive straighter that way with more thrust. Imho...


BUT! What do I know... Looking cool!

[Eodman]

Darrin, thanks for the input! No the motors don't counter rotate!

Remember this is the first build my son & I are doing. In effort to keep my 13 year olds attention we are getting it built before the water gets hard. Then this winter we will make improvements! Also this is for fun not racing!

I've been told that it may not be possible to get the EP1's to counter rotate! I figure once it's running I can contact Aquacraft technical department for info!

[Stealth Assassin]

Oh It should be fine!

Is the motor brushed?

[Eodman]

Aquacraft EP1's come as brushed units .... that said because of the lower unit is gear driven I'm told that it will stand up better to brushless motors! So you know where we are going with this right?

It's just for fun but it can still be fast Eh!!!

Just like everything else I have looked into this also. They will hold up for a while if you service it after each run. That being said it was never designed for the rpm range brushless will deliver. As I stated when I asked Steven about this very subject.

It's a good thing OSE stocks replacment gears hu

I say go for it. :)

Do it to it! If the motors are to much power...they always sell well in the swap shop.
