Delta Force Vortex hydro build

[brazildesigns]

Is that powercaps module just an add on to a esc?
Also , what are you using to fasten the top on the hull??

[j.m.]

You use hatch tape (clear scotch tape) to seal the hatch to the hull everytime you run it.

Based on the size of that motor, I'd have to say that it's too small to move this boat properly. Look into a 540 'L' or 'XL' size motor (36mm diameter, 65mm+ length, 5mm shaft...). You can get some cheap ones or expensive ones, it all depends on you budget/speed goal.

Do you have two of those batteries? Because one will only take a 60 amp continuous draw and the low capacity will serverly limit your runtimes. Wiring two of your packs in parallel would be a good option.

Good choice on the ESC, those work well.

Scotch tape , easy enough.
I was afraid the motor would be small, I'll look into another Hobby City has a few good watercooled setups . 5mm was what I was figuring for my outrigger so my hydro also.

what batteries do you suggest, 2 batteries could be done but what about the weight??
Thanks Brian

Remember, this isn't an airplane! Two of those batteries will not effect the handling of the hull. I've heard of people running this boat on two 4s packs.

LiPo batteries are light enough and so dang powerful...

This is a good build thread:

Laminating carbon cloth to the hull would be a better idea than the tubes for strength though... Especially if you can glue in the motor mount at the same time and reinforce that with some fiberglass/cf.

Try an 8L for 3s, that should be fine for sport running.

Ive flown only airplanes in the past and have many. I have been aquiring boats and have only ran the the 22"Pico, my Proboat Blackjack 26 is ready just havent had the time and this weekend isnt looking good since I plan on selling some of my planes at a club swapmeet. I have a 1/8 scale Miller American and 2 tunnels as well as designing my own rigger.
I dont really like the tube thing myself.I have seen that thread. The 8L is a FUEGO??
Brian

[j.m.]

It doesn't have to be. 8 turns, 'L" size 540 can.

This is an okay motor:

They run hotter than Feigao's and don't have as much power, but they're a ton cheaper.


I'd say basically try to replicate the other build, since that was his second boat (he knows where to put the stuff from experience). You can definitely PM him if you want any actual dimensions. Except, of course, the part about JBWeld and the tubes, you can do better than that.

I dont mind paying the price for the Feigao's , unfortunately the 8L is out of stock. the 8XL is available but it doesnt list a shaft dia. and i'm not sure if it will fit.
Thanks,
Brian

An xl motor will definitely work!

Do you have any 2s packs? 4s with an 8xl would fly... If your going to do 3s, go with a 6xl.

Jon

The UL-1 setup works excellent in this hull as well.

[brazildesigns]

I dont have 2s packs, I have 3s x2 but can get 2s packs. We talking 30c 3000+ mAh. I am pretty much clueless here with the batteries

[brazildesigns]

Rumdog,
where do you find the UL-1 set up you mention ? I am having a had time finding a rudder and strut set-up I like. I like the single unit setups like the silinger but there not available.I am finding it difficult to buy seperate units that will match up properly online. I dont have the knowledge to now the ins and outs yet, but I am learning.
Brian

[brazildesigns]

I have ordered a Feigao 540 6XL and a motor mount for my Vortex. I need a little help on the batteries for this set up so I can order them and my speed control. So far I have learned that 2 packs wired parallel but I dont know the mAh or the discharge rate for the packs using a 180amp esc.
Any suggestions

[j.m.]

The speedmaster hardware I linked to works perfectly.

Try these for batts:

http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=10282&Product_Name=Turnigy_4500mAh_2S_30C_Lipo_Pack

Two of those in parallel will easily take a load above 250amps continuous.


You'll also need a turn fin to complete the build along with steering linkages and a servo mount.

Jon

[brazildesigns]

Thanks Jon,
I will add those batts to my order. With the Speedmaster hardware am I looking for .21 size stuff? and the turn fin the same or a specific length?
Brian

[j.m.]

.20 or .21, there's not much of a difference. The .20 stuff is obviously just a little smaller.

Any battery like that will do, you don't need those specific batts. For example, if you'd like to have a hard case lipo there's tons of those at great prices too.
