Predator rigger hydro build

[andym]

JL, that in no way was ment as criticism, just trying to help .I myself are just learning the art of these speed machines. Once you get it running riggers are the formula 1 off rc boats.

that critism part was meant for me..since all i have is riggers i think i would know a thing or two on the subject..put foam in the sponsons..when a rigger is on plane the tub is out of the water.so your placement of rear sponson is not only useless but will look rather funny when its running..rear sponsons are just that "rear sponsons" they do the same thing that front ones do..just my thing or two

for the love of god man put some foam in those sponsons

Explain to me why. I was thinking I did not need it. I was just going to make a litte block to hold the inside of the rod. to me the foam is just extra strength that I doon't feel I need at this point and extra weight that I don't want. Please let me know if there is a reason for the foam, as I am new to hydros.

did you design that yourself??

No it is a predator the plans are online and can be downloaded for free. My next rigger will be my own design but I needed a sarting point to see what it was all about.

that was ment for everyone I am here to learn.

thanks I will keep that in mind for boat number two. feel free to help me out with any other tips you might be willing to share.

The foam dosen't weigh enough to matter, it is just a precaution in case your boat takes on water and dosen't sink, also adds strength and makes your sponsons really tough.

I could use a little advise on running gear. I was thinking this

any thoughts guys??

Mate go for the solinger hydro system. The best I can find

[Avanti]

I was thinking inline for SAW. do you think the offset would cause a problem trying to squeeze all the speed out of this set up on a buget?

[Avanti]

ok guys please advise me on a budget minded running gear set up for my rigger
I will be starting out with a 6 cell brushed setup and moving to a 8 cell brushless setup and would like to buy only one set of running gear so I need something that will handle the brushless setup.

I will need everything from the motor coupler to the rudder

[ace028]

I think the solinger set up is the best bet, I'm not sure about the straight line part, but for its price you can't beat the quality, I'm sure its plenty strong too. I think some of the saw riggers that I seen (not in real life) but on the net have a off set rudder.


Keep in mind that your brushed motor coupler is going to be a different size I think than a brushless motor.

[Avanti]

yeah I figured I would need two couplers

I guess I will go for the solinger stuff but it will have to be after Christmas

[Avanti]

what size couplers would I need for this set up? one for the std brushed motor 540 size and one for the brushless motor.

Also what size shaft would you recommend? there are two to choose from.

I can't wait till after the holiday I want to get this boat wet.

edit: found what I was looking for
std brushed motor has 1/8" shaft
std brushless motor has 5mm shaft

I still would like to know what size flex cable you guys would recommend .130 or .150
Does anyone know the stock SV27 flex cable size?

[Rex R]

SV uses a 0.15" flex. as for what size for your rigger...kinda depends on how big a motor(bl) you might use. using feigao's as an example you can prolly use a 0.13" flex for anything smaller than an 'xl' motor

[Avanti]

Thanks Rex, the .13 should provide a bit less drag too huh?
I plan on running the stock SV27 motor in it to start out than maybe the ammo 2300.
nothing to crazy

[Avanti]

Well I got motivated last night & tonight to get some more work done on the rigger. I got the front sponsons foam filled and assembled. I took the rear sponsons off, got the front mocked up for mounting. Made the turn fin and spare then mocked them up on the boat. All that it left is body work, hardware and paint. I'm gong with the soliger hydro with a .150 cable (trying to keep all my boats somewhat alike hardware wise).


front nose peice is done now too

[tylerm]

turn fin mount.

Nice looking turn fin bracket man, how thick is it?
Turn fin looks good too, alloy i presume?
