Delta Force Vortex 24

Hi Vortex 22" fans

can I ask some advise for a motor for the Vortex Hydro 22"

I have the boat built but just need to decide on the motor
I would like to run on 1 x 3s 4500Mah Turnigy Nano lipo
I have two spare motors to use and not sure what one would be the quickest
any advise appreciated and idea of speed and prop size?

I would go with the Turnigy 36/56 2600kv on 3s. It would be a similiar set up to what I'm running in the 24". It will be a rockett in a 22" hull.


As for a prop. I just ran mine today with a Grim 38X55L and I liked it better than my X440. You should have no problem swinging either one and would be a good start.

I keep telling myself I'm going to throw in a Feigao 8XL and 4S, but I have a hard time changing out a good set up that works really well. Who knows, maybe one day.

Im not sure about te 1 3s. I had that on a Pica 22" plastic hull running a 2881kv motor and Kept puffing batts. I agree with lipdaddy and would suggest using the set-up calulator at OSE, You can play with the numbers with your setups and get the best prop/power setup and get an approximate speed with a 640 prop 3s 2p 2 160 amps. I found this after my 22' DF was setup and with my Eagle Tree E-Logger confirmed what the calulator figured, 50MPH. Changing the pitch obviously will effect the RPM and the load on your system. I want to see if I can back off on the pitch and raise the RPM while lightening the load will I get the same speed, That Calculator will tell me.

Really nice! What kind of hardware (rudder etc.) are you running?

[lipdaddy]

All the hardware was bought from OSE. Speedmaster .21 flat bottom strut, ose-80052 rudder, proboat hydro turn fin. I'm now running a 8 XL on 4S, 120 swordfish esc and a grim 38x63L prop. This boat is a rocket and probably my favorite.

Perfect Ryan. Many thanks!

I have some left-overs from my SV27 project, so I could "recycle" some parts.

Speedmaster. I think it might be a ministrut.

[lipdaddy]

This is the strut I'm using.
