Vortex 22" on 2s or 3s

[sampit]

Any tips on building a Vortex?

I am in do deep on my own

and never had a hydro before, scarred to start drilling without some expert advise,

my first problem is battery placement for a single 2s or 3s along the hull or across the hull can you use the sponsons for batteries if using 2 x2s

my next problem I have to many different motors at hand

etti B29 4950kv 1 x 2s 5400

tenshock B29 3450kv 1 x 3s 3700

Turnigy B36/56 1800KV 5s 2p

Turnigy 36-56 2700kv 1 x 4s would need to buy more packs if this is the better opion

Do hydro's need to be set up with the weight down the centre line?

If I use 2 x 2s packs do you put them down the centre line or place them in the sponsons?

I have a lot to learn

am I getting carried away,
sure this would sink it

I ran my new one on one 6 and one 7 cell nimh. I plan to run it off of 2 2s batts, thats what the old owner did.

what motor are you going to use with your 2 2s, do you run 2s pack in the sponsons, or down the middle

I ran one with a Ammo 2600 and 4s1p. A 2s 5000mah pack in each sponson and an etti 150 with x637 prop. Ran a consistant 57mph! Very stable little hydro!

Rumdog
did it handle ok with the packs in the sponsons

i have 2 x 5400 2s packs i could use, is the Ammo 2600 the UL1 motor?

this looks pretty quick

[Rumdog]

Absolutely. Try to get the cg about 1-1.5" behind the back of the sponsons. It will rock! The ul-1 is around 2000kv. Mine was 2600kv, a bit hot, but ok with smallish props.

cheers rumdog,
can you explain the cg on a hydro
is it the balance point on the back of the sponson on a flat table
i have ajusted the motor so it rocks at that point and it about 1-1.5" behind the back of the sponsons
also is this the point it should balance on a finger,
newbie question

[Rumdog]

Yep, with all the gear in and hardware mounted balance from front to back . Using the fingers is the easiest way.

[sampit]

great im on the way

so does it need to lean slighty to the rear or balanced using the finger

[Rumdog]

Balanced, if it's leaning rear, then your fingers are not at the cg.
