Do you mean "no rudder" or in-board ?

My transmitters allow me to unscrew and rotate the sticks by 90 degrees.

Some transmitters can "mix" a throttle and rudder signal for the purposes of V-tail aircraft.

You can get a device to fit between receiver and servos and another speed controller or drive two motors with one controller and fit a rudder.

You could fit a rudder  and drive two motors with a single speed controller.

To control throttle on two motors you would need two speed controllers.Then get a transmitter that allows you to unscrew and rotate the rudder stick by 90 degrees to make two throttles OR do some surgery by adding resistors to mix the throttle and rudder sticks together (cost is pennies) OR use the mix option if the transmitter has one.

what sort of space have you got in your hull because i was looking at one in u s a  same boat i 

think  there is not a lot of room  in the hull you will probably have to put the small servos in and

check on the set up for room for esc  and batterys  i would double rudder it as you said

hope this helps mick

it depends on the set up you require you can  get a single  speed controller now  that does the twin 

motors i think astec electronics do it not sure of the price i  do a couple of my boats on twin shafts 

and twin motors but run them on single speed  controller  but this depends on the setup you require

i have other boat s on twin esc but that is on 3 or four channel setup  as i said its all about price 

you are willing to spend and different motors esc and radio you are useing if you go to your local 

model shop they will advise you or better still your local boat they  are always happy to help if you ask 

the members hope this helps mick

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
