hi looking for help,my daughter brought me a ready to go r/c american custom boat when she was in usa ,but when i took it to our local model club pond it would not work when other boats in pond.so last week took deck of and stripped all elec,out going to put speed controller and other elec  in,my problem is the boat has in rudder it had two motors for steering i am putting in two new motors,how do i get motors to control steering, thanks

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.

yes i mean no rudder  sorry should have said that  the props controlled steering.i hade a servo .receiver and switch kit from other boat ,but as it  has no rudder i dont know if have to fit another receiver to work steering. thankstom

[60wattParticipant @60watt]

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.

thanks tom been sitting looking at it again, i was thinking .adding two rudders servo ,speed controller. and two recievers one for each motor ,or is it one reciever and two speed controllers,one for each motor ,.hugh

hiya hugh

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

[Hugh ConnollyParticipant @hughconnolly85056]

thanks mick there is plenty room in hull when u take every thing out. wat would be the right setup,two speed controllers or two recievers.  cheers hugh.

 hiya hugh

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

[60wattParticipant @60watt]

Hugh,watt transmitters do you have?

[ashley needhamParticipant @ashleyneedham69188]

All . Yes good question….Do we take it that the boat works fine on its own but when other bods turn up and use their radios does yours then play up ?    Ashley

[60wattParticipant @60watt]

I meant by "watt transmitter?" did Hugh have access to an older Futaba or Hitec handset which would have meant the only extra expense is one additional esc and five minutes of his time.These handsets can be customised to make   right : throttle    left : rudder or two tank style throttles for steering by motor.

hi ashley yes if other boats in water the one i have wont work,it is a boat ready to put in water,i only had it in water once,i have took every thing out of hull and hve empty hull now. cheers hugh.

[Hugh ConnollyParticipant @hughconnolly85056]

hi Tom r/c i have are HITEC 2CH.RANGER11, 40M.AND2CH,40M FUTABA,MEGA TECH 2PL. thanks hugh

[60wattParticipant @60watt]

I’m sure one of these handsets will let you rotate the rudder stick by a quarter turn.

Tom

[Hugh ConnollyParticipant @hughconnolly85056]

thats fine tom iwill see how i get on thanks all for ur help,im not to bad at building but always seem to have problems with r/c fitting,cheers hugh

[mickParticipant @mick]

hiya hugh

i am glad you are getting on ok  and hope your build goes ok  what motors areyou going to 

use in the boat the originals or different  just being nosey let us know how it all goes mick

[mickParticipant @mick]

hiya hugh

if you have twin motors look up the p94 mixer at the http://www.action – electronics .co.uk it is a 

two to three channel mixer check it out  hope this is of help mick

[Hugh ConnollyParticipant @hughconnolly85056]
