First build... Cheap boat, lots of power

[masonis1]

So here it is.. i got this cheap old boat from some online place for 30 bucks a while ago... Its a deep v as you will see in the pictures... It was brushed twin motor. I am trying to convert to brushless. Well now i have it where its 1 motor and a rudder. So... Heres the parts list.

Turnigy 3656 2700kv motor
Turnigy 120a esc
Turnigy nano tech 3s. 45-90c
Traxxas rudder assembly.
Boat hull

I tried this in many tuning options.. either way, it sucks air... I have reved it up very low sucked air... Wow right! I have about 4 different props of different pitch i can try. Havent tried them all but i am willing to re drill holes... And start fresh. I want this to run good. Help me know where to drill and what i can do. I need help choosing shafts, and other parts.


Now the pics...

[masonis1]

Anybody know of help??

[Make-a-Wake]

We need a picture of the rear end as it is set up now to assess what you have....

[masonis1]

Ok. I will get some better pictures.. i am willing to re drill anything and start from scratch

[LiPo Power]

How long is the boat?
Post some pictures from the top to see the room you have inside...

[masonis1]

It is around 28 inches if i remember correctly. I will have pictures up in a bit

more pictures

i know its dirty and a lil nasty inside. the black is abs to seal up some holes and its been sitting a while so its kinda dirty..

I mean no disrespect, but I would walk to the nearest dumpster and heave that thing where it belongs.

[masonis1]

I dont care what you think. Just help me get this thing running...

[LarrysDrifter]

Get one of these and use the parts you have.

Youre trying to build a headache. I say this because ive been there and done it. The hull isnt worth it. The DF is cheap and will handle much better. Its a better start for a guy that hasnt built a boat before.

[masonis1]

I might have to but i want to TRY and get this running... Just what do i need to do.. ill keep that boat in mind... I would still need lots of stuff...

[masonis1]

Whats better?
Mini storm or delta force...
They use same hardware and motor just the mini storm is smaller...

make sure the prop is not right against hull, move out more

[LarrysDrifter]

You answered your own question.

[masonis1]

I will try this hull first and save for the different hull but which is better?

[masonis1]

How far out should the prop be?

[masonis1]

For a rudder, would a 75mm aluminum rudder work fine?

[masonis1]

Here is what im thinking for parts
Flex cable. What size?
Drive dog
Aluminum rudder

I will put the rudder on, run the prop out, what angle and how far out, make a plate for electronics and servo.

Add more foam, how much and what kind???

[Make-a-Wake]

The exit hole for the prop shaft should be up higher on the transom............about 5-7mm up from the bottom. The "stinger"/tube should stick out about 2".

[masonis1]

Ok... I dont know if any of you use paint, but it would be very helpful if someone could draw where i put the prop and everything...

[masonis1]

Ok. So from the lowest point of the hull, the hole should be at 5mm or would 7mm be better. Which is better, which angle should it be at. Im going to tryb drilling the hole tonight or tomorrow and need to know what all i need. As much info to what needs to be done for the drive shaft... I will be running a rudder but have no idea where i should mount that either. Like have it off to the side or what?

[srislash]

Here's the rudder I would put on from here http://www.offshoreelectrics.com/pro...prod=ose-80051 I would offset it to the right but only enough to clear the biggest prop you would be using(35mm or maybe a 37).This rudder should end up beside your prop if you were to look from the top.If you mount the stuffing tube with 1.5 inches outside the hull I would go with a 5mm center for your hole.I assume from your posts that you are just thinking of running the tube as opposed to a stinger or strut for this "experiment".

[masonis1]

I am open to ideas. Should i get something for the rod.. ok.. lets start this, what should i get.

The rudder-what size is good
Drive line- kind of line, adjustments!
What? I have no idea what to get or have...

Is this rudder good? Also what should i do for the drive system. I hear some just say run a line out, you say run something else. Im not very firmeliar with all the names of stuff so pleasec if you would, say it in a noob form.. hahah

[srislash]

First of all,don't get in a panic to get things done overnight.You should take some time and read and study what others have done.I have a little hull(25") that I just have to run again even though it is probably not worth it.But I've had it since I was 18,so...

The rudder you posted a link to would be fine as long as the transom(rear mounting surface)is strong enough to hold it with only two small bolts.

[masonis1]

For the transom??? Could i add a piece of plastic of aluminum to stiffen it up? Also, what were the things for the drive lines i needed. Everything i get here should be able to cover over onto a different hull correct?

[masonis1]

Ok also, for the drive line, you said a 5mm hole, what line and tubing should i use?

[srislash]

I think this would do the trick for you http://www.offshoreelectrics.com/pro...t-oc6str-130da all you would need is an appropriate sized brass tube to put the flex and liner in.(5mm center hole)

[srislash]

Ok also, for the drive line, you said a 5mm hole, what line and tubing should i use?

I said 5mm for the center of the hole.Size will depend on the stuffing tube.
