neu 1515 1y with .150 flex

[Chuck E Cheese]

what are the opinions on using a .150 octura flex shaft/440-445 prop on a neu 1515 1y in a cat/inboard tunnel hull? is this going to work or do i need to go with a .187?
thanks

1515 1y and .150 is the same combo I use in my Whip 20 and have no problems with it.

Ditto that... .150 is fine for that application...

i use the exact combo in my skunkworks cat without any probs

are you guys using with or without liner? i have always used a liner thinking that it helps keep the water out. this application is actually an inboard tunnel hull that is going to have a "S" bend stuffing tube like a rigger.

i am building an FE version of this.

Interesting... Never seen anything like that before.

You'll probably want the motor as far back as possible to keep the hull balanced.

i got it here on OSE advertised as an FE tunnel i was planning on using a outboard on.... it is not! i spoke with the manufacture and got some recomended set-ups and decided that the inboard would be a good deal considering i run salt watter and was concerned about the FE outboard anyway...
i havent figured it out yet but i was planning on putting the motor all the way forward and batteries in the back. this way i can change the COG from 20-35%. i checked all my nitro tunnels and they are around 27%. if i put the batteries behind/above the COG i can slide them around and change it easily. the battery/motor box is pretty big so i have alot of room to play with. i was thinking something like the nitro set-up only replacing fuel tank with battery and engine with motor...

[j.m.]

So your placing the batteries on either side of the flex cable? Or does the flex exit the hull before the batteries?

Remember, keep the batteries as low as possible.

[Chuck E Cheese]

havent got to that yet but they can fit either way. when i get the hardware mounted and start the build i will have a thread going. i will post a link here.

[j.m.]

That looks like it would be better than having the stuffing tube out in the middle of the tunnel....

[Chuck E Cheese]

i still have to put everything in it and check it out. i originally wanter the motor in the back. the hardware will be here monday or so and i can lay it all out and play with cog to find out what works. i am a little cautious and want to make sure i can move batteries and change from one extreme to another reguarding cog.

[j.m.]

Having a rudder and stationary prop will definitely help with spinouts.

are you guys using with or without liner?

I always build without teflon. Much smoother driveline. I will also back-up the idea of having an "s" bend in the stuffing tube. You will get some who build with and some who build without liner. I am following the advice of Jay Turner who suggested liner-less a long time back. Just my personal preference.

Thanks TTH

I don't use teflon anymore. .150 cable running in 7/32" brass is sweeeet.
