Mini Twin Cat Build

[wakeboardfusion]

Bought petes plans. They look great. I bought some of the wood yesterday but they didnt have 1/8th. I hope to start cutting on friday. I plan on running twins.

These motors should work well.

Is there any inrunners that would work for easier cooling?
Any more suggestions? Thanks

I don't recomend that rudder, mostly because its mount is not symetrical, but i'm sure it would work fine.

I used those blue struts for my build, they work ok, I turned a set of octura 3/16 bearings down to fit and ran a stepdown shaft to use counter rotating x430's with .130 cable. Don't forget to get reverse lay cable for your boat.

Here is a link to my build up, check it out and plan your build a little better then I did, you can see in my haste to build I didn't angle the motors and ended up with a undesirable bend in the flex cable. Also this build was the prototype to those plans, so your boat will be better then mine is.

I am starting a new build of the same boat from my dads plans. So that will be cool to se eachothers progress.

I am going to be using small etti stinger struts for this build, they are being modified by Jeff Wholt to accept ball bearings, so my drive line will be super smooth this time lol. I was also considering some Scorpion brushless outrunners but am also thinking about the feiago 380 motors here on OSE because there are motor cooling jackets for them here on OSE.

Here is the rudder I will be using, there are 2 different ones I think.

I know they seem long, but when I mount them they will stick out from the rear of the boat about the same as my initial build. I will post pictures in my build thread once I get them.

I use that stinger on my bby war zone jr. They are a bit heavy, do you think it would be too much weight to have two sticking out?

[ace028]

I hope it's not too heavy lol. Well I guess I will find out.

[wakeboardfusion]

Im trying to find some motors to run in the boat that are watercooled. I am guessing these are too hot. Or will they work. I guess I could use these on 2s instead of 3

[ace028]

I think my dad was going to try out those or some similar to them. Maybe give em a try. They may even be over rated in KV, plus over powered = just right! lol.

[wakeboardfusion]

So, should i stick to 2s or 3s with em?

[ace028]

Your choice, I would go with 3s, but thats me. Did you see my vid of my other mini twin cat? It was quick, running on 2s with twin 3600KV motors, for me it wasn't fast enough though.

[wakeboardfusion]

Ill go 3s because then I will always have the power available.

[ace028]

Sounds like a good plan.

Any build progress?

[wakeboardfusion]

No progress yet. I should have some by Friday.

[wakeboardfusion]

I got the skins all cut out today. I still need to go buy the rest of my wood. Nothing worth pictures yet.

Try this motor it has an 1/8" shaft you wont have to buy any thing custom to run ithttp://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8594&Product_Name=2848SL_3900kv_Brushless_Inrunner_(Wat erCooled) and it is not as hot as the one you listed and it is the right size for the space

Try this one it will fit the space and isn't quite as hot and only runs 900 rpms faster than the ones I use currently

We will be building the new generation with you so watch for our posts (we got ours laser cut) we both did the scratch thing and decided we wanted an awesome one this time with a great degree of accuracy. and this one has some special little things which we need to address when it comes to Skinning the Cat! I have re designed the stringers to accept a bevel towards the bulkheads to give a smoother and better attach point for the bottom of the sponsons,

[peells]

Hey Brother any updates?

[ace028]

Can't wait for more updates.

[peells]

Any progress here?

[wakeboardfusion]

Sorry, havent been around in a while. School and work keep me busy, especially now with it being about over for the summer. No progress at all.

[peells]

Well just keep an eye out for our builds and use them for reference when you get back to building, the hull really goes fast it is just the planning for the accessories that takes the time Oh and the painting.
