HELLO,
I AM BUILDING A BAIT BOAT,I HAVE A 35 INCH LONG FIBREGLASS HULL 10 INCHES WIDE,
AND I DONT HAVE MUCH IDEA ON HOW TO PUT THE INNER WORKINGS TOGETHER,I HAVE READ
A LOT OF BLOGS ON HOW TO DO THIS YET MY BRAIN CANT BE SURE IF I HAVE IT CORRECT
IF I PUT A LIST OF THE WORKINGS I THINK I NEED CAN SOMEBODY TELL ME IF I AM ON THE
RIGHT TRACK.
I WANT TO USE
PLANET T5 2.4GHZ COMbO SET 5 CHANNEL FOR MY OPERATING SYSTEM
MOTORS--2X MTRONIKS VIPER MARINE PLUS 2X MTRONIKS MIXER WATERPROOF(w-tail) to work the two motors at the same time
SERVO SETUP TO TIP MY BAIT BOXES
2X FUTABA S148 STANDARD SERVOS
2X MTRONIKS MIXER WATERPROOF(W-TAIL) TO WORK THE SERVOS AT THE SAME TIME
would this setup go together or am i on the wrong track,thanks to anyone who can help

hello i am new to mayhem and new to rc building.
i have just brought a 35 inch long 10 inch wide 6 inch deep fibreglass boat and i need help in kitting her out.
i have read a few things on how to run a boat but i may have the working order wrong in my head,any help would be great.
my idea for the workings of my boat are as following.
operating system.
planet t5 2.4ghz combo set 5 channel.
motors.  2x mtroniks viper marine 20.
2x mtroniks mixer waterproof w-tail, to work the motors at the same time, (if possible)
servo setup.  2x futaba s148 standard servos
2x mtroniks mixer waterproof w tail,to work the two servos at the same time (if possible)
will this setup work if not could somebody show me the right way please

First welcome to the mad house you dont have to but it helps  .
some pics would help with advising you on set up.
 what type of craft is it ?
To run your motors together you just require a servo Y lead or just use a higher amp speed controller that will run both motors.
a single servo is more than adequate for the rudders

Whilst you will get good advice here on the Forum ( although it will doubtless include conflicting ideas) why not join the Moorhen Model Boat Club that meets in Harlow? There you can get face to face advice and help - and somewhere to sail your model when its finished!

A good start. You should be able to get up and running with this.

By the way.....  CAPITOL letters are regarded as shouting on the Web so are not used.

regards

ken

[eddieneil22]

sorry about the capital letters i havent been on a forum befor wont do it again,
what do you think of my running gear e.t.c i havent a clue if this will work,i will put a befor picture of my boat on for you to see,once i work out how to do this.

thank you ron,thats the first piece of my education on this site,thank you and yes barriew i will take a look at the moorhen club thank you,i got into trying to build my own boat because i was given a new kidney from my brother in 2011,i needed a hobby,thanks everyone

motors.  2x mtroniks viper marine 20.
2x mtroniks mixer waterproof w-tail, to work the motors at the same time, (if possible)
servo setup.  2x futaba s148 standard servos
2x mtroniks mixer waterproof w tail,to work the two servos at the same time (if possible)

Viper marine 20 is an ESC, for controlling a motor (or a few motors, if they are not too large).  It would help to know the type of motor, and the type of boat/level of performance expected.
A mixer is a device that goes between the receiver and the ESCs to use rudder channel information to influence the signals going to the motor ESCs.  Just one per model usually.
Just one standard servo is enough to work a pair of rudders with a mechanical linkage.  If a mechanical linkage is not possible, two servos can work in unison via a Y lead.  It is rare for the two rudders to need to be operated independently.
If you have a club nearby, that is probably the best place to go, as Barriew says.

thank you malcolm,
i have included some pictures of my boat,i dont know what kind she is i brought her off e bay £20.

MFA Spearfish?

As others have stated, there will be various ways of doing and still getting what you want!

1. What sort of performance are you expecting?
    Fastest boat on the lake, hellfire machine,
    Fast but reasonable run times, eg 15 minutes,
    Reasonable speed but good run times, eg. 20-30 minutes,
    Speed not important but I want good manoeuvrability.

2. How much are you willing to spend?

3. How deep are your pockets?

hello,
i just want my boat to get from a to b not fast
running time-2 hours
i want her to turn on the spot
money-i will buy wat i need when i have the money
my pockets are as deep as my hands can get
as much as i can work out would 2 540 motors do the job
neil

[malcolmfrary]

A mixer + 2 of ESCs will allow it to spin on the spot.  Using a 4 channel set and tank steering with the two sticks you get the same effect without the mixer.  Some higher end radios do the mixing at the transmitter. 
For driving a bait boat on a lake, 545s (slower running, more torque, lower current drain) might be a better bet.  On moving water, you need a lot more performance if you want to get the boat back without a long walk downstream.
Getting a long run time on one set of batteries can be a problem, but a lot depends on the duty cycle.  If it involves a cruise out laden and a quiet cruise back then a rest switched off, 2 hours is probably no problem since there should be plenty of options regarding the weight of battery that can be carried combined with the payload.

[eddieneil22]

thank you again malcolm,
can you suggest, a good 545 motor,plus what size batteries would you suggest,would their be any chance of a drawing with names of parts needed to run from a planet t5 5 channel,of two servos to tip box two running motors to power my boat
would be very happy  neil

[eddieneil22]

i did try to use a tank motor but i conected a servo to the wires that used to work the gun and the whole lot packed up

[malcolmfrary]

A good set of drawings here - http://www.modelboatmayhem.co.uk/forum/index.php/topic,6169.0.html - a 545 is a generic motor, 54mm long and having 5 poles.
The ESCs for the motors just plug into the channels that correspond to the sticks you intend to use for each motor.  The hopper control (why 2 servos?) plugs into the channel corresponding to the stick you want to use.
For the size of batteries, only you can know.  Factors are knowing what weight the boat can carry without being in danger of sinking and how much bait you intend to carry plus the weight of everything else.  Once you know what your weight limits are, you can start considering batteries.  Lead acid are relatively easy to look after, but are heavy for capacity.  NiMh are less heavy for the same outside size, have better capacity and are also easy to look after.  More modern stuff involving lithium packs more energy into less space and weight, but is picky about its treatment.

thank you again malcolm,
the drawing was very helpfull,it will take me a while to fully understand it. just found out what a esc with bec is.
the idea of the two servos is as picture.
neil

[eddieneil22]

hello malcolm,
can i ask on the drawing you gave me,what amp inline fuse should i use and i cant seem to find a 4.8 volt ni-cd 4 cell battery any where i have found 4.8 volt batteries,will they all do the same job.
neil

[derekwarner]

Hullo Neil....I have no knowledge of 'bait boats'    ....but find your image below interesting
For increased rigidity of the tipping motion.....you could consider
1. Reversing the orientation of each servo [flip 180 degrees] so the actual servo drive axis is more inline or inboard of the tip box mass centre
2. Install a second parallel plastic tipping arm to the other side of each box
3. This may require bent arms

[eddieneil22]

thank you derek,when you say install a second tipping arm,do yo mean a non working motor arm,just a arm that is operated by the movement of the first servo.

New on the market for replacing the hopper servos are some rather nice small winches with enclosed drums.  I saw these on the stand of component-shop.  Using their wind-through capability they would be very capable of winding the hopper down and back up again, with very accurate adjustment to all points between.  Drum diameter is about 1", and they come with various options regarding number of turns, so quite a versatile bit of kit.  It might need a heavy duty servo to handle the hopper as shown, and the costs for the drum winch are very comparable.
When the drawings were done, NiCad batteries were the going thing.  They have almost entirely been replaced by NiMH batteries, and the packs can be regarded as interchangeable. 
The fuse value depends entirely on the actual maximum load.  In a multi-esc setup, there should be one fuse per esc, and it should be less than the esc max, but more than the motor pulls under load.  Without a meter, the easy way is to have a pack of assorted fuses and work up until you get one that doesn't blow, and use that value.  With 545s, probably 10A each.  Lots of threads about fusing, and loads of information on Action Electronic's website.

[eddieneil22]

thank you again malcolm,
the drawing you give me was if i were to use a rudder,is there a drawing without useing a rudder,but to have both motors running at the same time and use the servo as my tipping motor.
thanks again malcolm this site is so helpfull.
