I use a .130 flex on my .12 rigger, but I dont have any idea how strong your motor is? Isnt the transom 1 piece of wood 1x3 roughly?

yea lol i still need to do the transom doubler, and the rest of the tub parts all over again! I got no time as i am in the middle of a 5000 word essay so i gotta finish that. I should be able to have the whole thing finished in the next few weeks, the hull and other parts i mean. If it will take the power of a .12 engine the .130 flex cabel i think would be fine with the brushless setup i have chosen. Also should we follow the build instructions on the Firefighter Boats website for the .12 rigger? I may be able to get some pink foam but i dont know yet.
Thanks

I followed the .12 rigger building plans on the web sight, its up to you if you want to. I found it to be helpful with the order of operations and why thing are the way they are. And yes you do need some foam (pink/blue) the foam need to be able to be sanded without falling apart.

Alrite thanks ill just have to find some I know they have it at my school but i am assuming that it costs alot of money and I won't be able to have some. Hmm do i really need rear sponsons with all this power because i thought they were just for underpowered boats that need help getting on plane? Ok whatever im out

My understanding is that the rear sponsons help the boat in turns, and that they should not really be in the water under full power.

But on top of that, it seems they would help keep the boat afloat when the boat is stopped. They say your boat should float when it is full flooded with water (to include the radio compartment). Not sure of it would without the rear sponsons...

But, I have seen pictures of boats without them...

Hmm taylor just told me that the 9XL would be too big, ok.... SO I think i may get a 540 7L so i ight be able to race on internet racing on rum runners in the N2 hydro class.
Dan

hmm progress is amazingly slow, i still need to get that foam!!!! Ok i still only have a few parts of the tub to the rigger done. I have a question can you use fuel tubing as a stuffing tube?
Dan

Drmeff

I dont think that you should, I have never done it so I dont know but I would think it wouldnt be as slick at teflon and heat up, maybe melt even but idk!

Sean Bowf

Just as an FYI about terms, I am pretty sure the "stuffing tube" is the metal tube that runs from your motor down to your strut. I think you are talking about the "teflon liner."

And as was already said, I would say that fuel tube would not work. Fuel tube is rubbery, or sticky. Liners are supposed to be slick.

Sean

Woodmandan2

Alright, oh yea i got my words screwede up, i meant the liner. I guess i will buy some teflon liner somewhere.
Dan

Sean Bowf

Another option is to use a smaller tube and not use a liner...

Sean

Drmeff

just make sure you use a lot of grease if you dont use a liner

Woodmandan2

I FINALLY GOT FOAM!!! I am gonna use a liner and i am also going to have to buy LOTS of parts from the usa. Could you guys reccomend some flex cables /liner/stuffing tube from tower, because they ship international. I just bought some balsa for the rear sponsoons, and the bulkheads. can i use this balsa for the front sponsoons or do i have to use plywood. I would really like to use balsa because i can buy it in strips and not huge sheets.
Thanks
Dan

Woodmandan2

Ok can someone please tell me how thick the sponsoon wood is?
Thanks
Dan

Sean Bowf

If you are building from the plans, it should be on the plans. It is a mix of 1/32 and 1/16 ply.

Sean

Woodmandan2

I CANT BELIEVE IT. I walk into the nothing hobby shop and i get CF tubing!!! can i use balsa?
Dan

Sean Bowf

For the outside of the sponsons?? I would say no...unless you are going to fiberglass over it or something...

I do have some balsa on the inside of the sponsons on my larger boat.

Sean

Woodmandan2

Oh because on the plans it said foam with ply covering or balsa for the rears, and i duno 4 the front
i am building the 6 cell version. Do you have any guesses for the thickness of the wood, or should it be the same as the baby rigger?
Dan

Woodmandan2

Could someone please tell me what thickness of wood is needed for the top, bottom, and the different sides of the sponsoons? and i just bought some very sticky double sided tape will it work for attaching the sponsoons?
Dan

gooycheese

Ok if this is a .12 rigger then i would say you will use 1/32 on all sides except the side the boom tubes enters. I am just guessing on this if its for a .21 i would guess 1/16 all sides and 1/8 boom tube side. Also dont forget to consider the turnfin need to be reinforced on the inside of the sponson. I am using double sided servo tape to attach my rear sponsons.


Paul

On my .12 rigger sponsons I used for the sandwich 1/16" ply 1/8" balsa 1/2" foam 1/8" balsa 1/2" foam and then wrapped everything with 1/32 ply.


Paul

Woodmandan2

Ok Thanks Alot!! Does anyone have any Ideas for the thickness for the bottom of the boat? I will go out and buy that today.
Thanks
Dan

gooycheese

If its a .21 i would guess 1/16" if it a .12 i would say 1/32" same for the top.

toyotatruckin

mine are from the inside are 1/16 ply-1/2 foam-1/4 balsa-1/2 foam, skinned in 1/32 ply.. Tub outside's 1/8"ply doubled in engine bay only, top and bottom 1/32" ply..transom if i remember 1/16 doubled with 1/8 ply (.12 rigger)

Woodmandan2

Ok thanks alot. I will go out and redo some things, i thought at first i could make everything out of 1/8 Ply, so i bought a whole sheet.
