Another Outrigger Predator project!
 

After reading the post of the Predator outrigger i've dicided to built one!
I'm going to by the balsa today.

Question: May i use a TP2100 3s 15C ( i have two of those)?

Question: What kind of brushless motor should i get to it?

Question: What ESC should i buy(limited budget)?

I bought a 75mm rudder on ebay, will it be ok or i started the wrong way?

I'm thinking buying this strut 4mm

http://img.auctiva.com/imgdata/3/2/9...5971432_tp.jpg

Kit includes:
4mm flex cable, teflon lining, brass tube x 1 set, squared end prop shaft (no soldering needed) x 1
drive dog x 1
tail nut x 1
teflon washer x 1
strut and bracket x 1
Is anything missing here to work ok?

Here in Portugal we do not have this kind of parts so if i broke something i have to order it
on the web so.....

This is my first boat so any help.....:)
Thx

The 3 cell packs can be used if both are placed in parallel. If you wish to do it this way a motor than can be selected.

Yes, i can use it in parallel.
I already made the sides of the rigger in 3mm ply, i'll post some pics tomorrow.:)

RE: Another Outrigger Predator project!
 

What is your overal length going to be? How fast do you want this hull to be in mph or km/h?

Ryan

RE: Another Outrigger Predator project!
 

That is the rudder I have on my Pred and fits great. I built mine with a 19" tub. I also have a Solinger 3/16" aluminum strut for it. I will be trying a bunch of motor/lipo combos in this one.

RE: Another Outrigger Predator project!
 

The lenght will be 20'' and i would like it to be FAST!:D

RE: Another Outrigger Predator project!
 

I used 1/8'' ply to built it.

Today i'm going to buy the 1mm balsa for the rest of the rig.

RE: Another Outrigger Predator project!
 

Some good ESCs here that are pistol comp... http://www.hobbycity.com/hobbycity/s...2&v=&sortlist= (SuperSimple) and also the BP ESCs here... http://www.bphobbies.com/view.asp?id=V815101

RE: Another Outrigger Predator project!
 

Oh yeah, looking good so far! :D

RE: Another Outrigger Predator project!
 

You can go with a 380XL motor or 540s motor. Which ever fits best. The wind will be around 2900kv.

Ryan

RE: Another Outrigger Predator project!
 

Where do i find those motors at a good price?

nice to see so many people building the same boat, to bad you guys are not all in district 6 impba we would have a class!![&:]

RE: Another Outrigger Predator project!
 

I measure the boat and it as about 22''.
Both the 380XL and the 540S have the same wind?

RE: Another Outrigger Predator project!
 

Don't worry about the wind number. As long as the motor is around 2900kv for 11.1v LiPo you should be good to go.

Ryan

RE: Another Outrigger Predator project!
 

Ok!:)
What about the strut i posted earlier?
Will a 60A ESC do for it?

RE: Another Outrigger Predator project!
 

This is what she looks lke right now

RE: Another Outrigger Predator project!
 

I search the "hobby" site and came up with this Turnigy B36-40-07 2900kv Inrunner
Anyone tryed this one?

RE: Another Outrigger Predator project!
 

I actually have one on the way to put in a surfer for a "fun" project. Or something for the girl friend to run. :D It may be a bit small for what you need but should work. I'd start with a small prop if you do decide to go with it.

Ryan

RE: Another Outrigger Predator project!
 

From the hobby site or another, what do you recommend?

Rui

RE: Another Outrigger Predator project!
 

Those are really only good for planes that don't draw too many amps. Their rating is nowhere near the requirement for a fast 6 cell rigger.
(100-120amps)

If you don't want to go TOO fast, (maybe about 40) this might do:

BTW:
Hobby City just put two boats on their website.

RE: Another Outrigger Predator project!
 

I've got a 2 cell LiPo rigger and it does 55mph and does not draw anywhere near 120A. More like 80 and it is 27" long. On 11.1v that would only be 50A. I'm running a motor that is only 48mm long as opposed to the 40mm motor above.

If you are drawing 120A, 2P packs are a must or there will be serious heat issues.

Ryan

RE: Another Outrigger Predator project!
 

So, i should get a 120A ESC?
I'm going with the Feigao 540S 12S 5mm shaft and the strut that is in the picture.
For the 4mm strut what prop from HERE do you recommend?

Rui

RE: Another Outrigger Predator project!
 

i'm talking about a safe rating for the equipment. You don't want to run everything at full tilt.
