Neil.......here is a mud map of my thoughts 
1. servo is more centralised with the tipping box
2. a set of parallel tipping arms are used
Essentially just minor revisions to your design.........Derek

[eddieneil22]

very intresting derek,thats the way iam going to go thank you i was so set in my mind on my idea that it stops you thinking about other ways of doing things,thank you,
neil

[Martin (Admin)]

Or, if you are just "dumping" the bait out of the hopper, they could be spring loaded and a short arm on the servo arm just latches it down.

[eddieneil22]

hello martin,
yes thats another idea,my main problem at the moment is to get the boat running,getting a list of the right parts,i dont want to spend money on the wrong items.
neil

[malcolmfrary]

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.

If you run 2 motors independently or using a mixer, just ignore the rudder servo. 
4 channel 2.4GHz sets are cheaper these days than 2 channels sets were only a very few years ago, so it makes sense to go that way.  This does mean that you have a "spare" channel or two for jobs other than driving and steering.  Using a servo on one of those channels is just a matter of plugging it in.  The mechanical arrangements are another story.
On the end of both links, there are several drawings, they just need looking for.

[eddieneil22]

thank you malcolm,
i will be useing your drawing ,you have been very helpfull,thank you
i started to do a bit of building work today,long way to go.

How much weight in each hopper Neil?
The spear hull was designed from a fairly
fast cruiser
That sort of weight on the stern might
not be a good idea.

If this is purely a "A" to "B" then back to base why not just use one motor and one propeller (save on £s).
Also have the bait Hopper fixed at a tilt with a door that operates either from a separate servo or use the spare movement of the rudder servo using the "trim" lever on your Transmitter.
 
Regards.

hello ned,
i have had 2 kilos in the back hopper,and i needed 1 kilo in the front of lead cut to shape,i have got half cut plumbing pipe to go on the sides and back she floated quite level,i havent got the inner workings yet,that should even her out
neil

[eddieneil22]

hello big ada,
i really want to go with the two motor steering,as you may have read,i know very little about the inner workings,but with the help of people on this site iam learning a lot,good site,i was thinking of the open back hopper but that would have made the back of the boat look uneven.
neil nice to meet you

[eddieneil22]

it will be more stream line when i have finished

[eddieneil22]

hello i just brought a cheap futaba challenger transmitter and receiver 5 channel and servo and charger pack,will it be alright for a beginner like me,i should have asked you all first,but it just came along
neil

[catengineman]

What is the Frequency ?
I think that it will be 35Mhz if it is then it is for AIR use only in the UK

[eddieneil22]

hello catengineman,
it is 35mhz,will it not work on surface land then i dont know a lot ,i picked it up for 15 pound,so i havent lost a lot if its wrong.
neil

[eddieneil22]

i just read that it could bring planes down,but because i will be useing it in the middle of nowhere fishing,will it be ok,or is it against uk law.
neil
i just read the range is quite far with 35mhz,

[Netleyned]

It is illegal to use for boats or cars.
You could always try for a swop on here.
Somebody may want it.


Ned

[eddieneil22]

dear netleyned,
i will look to see if anyone  will swap for a transmitter  that will suit my boat i will pay or the swap is greater,because i am new to rc its hard to look up some facts untill the problem arises.
thank you for your advice neil
it says its fm does that make a diffrence or is it the same

[malcolmfrary]

FM and AM are mutually incompatible.  AM is simpler and cheaper to make, but more prone to interference.
For surface use, 27MHz, 40MHz and 2.4GHz are legal and readily available.  35MHz is a big no-no.

If you had chucked another £15 in the hat, you could have got a brand new, virtually interference proof, legal 2.4GHz outfit.


2kilos is a lot of weight to put on top of a boat, there might be some stability problems, especially if there is a chance of sidewinds and/or following waves, unless a lot of attention is paid to ballasting low in the hull to increase stability.

[eddieneil22]

thank you malcolm,i am learning the wrong way,will have to sell the set nd get the plant t5 i really wanted,
neil
i think at the moment the only modeling i will be good at is socks

[catengineman]

Before you venture into too far on your build have you looked at the other bait boats.
As mentioned you seem to have a very large payload to contend with and when that is "dumped" the balancing ballast will then make that boat deep at the other end to where your load was. (unless it is central to the vessel.
Als the larger the vessel the greater the windage and current can have on it so that then needs larger motor(s) and so larger (higher capasity batteries)
Have you though about small often deployment of bait,
twofold in my suggestion.
1, smaller craft to build carry and handle
2, more fun as you get to "play" with it more often.
I'm not saying fishing isn't fun but if you dump 10 kg in a spot then return the craft to shore "thats it"


my idea would be to dump bait at point A - return for second load, cast line to point A - ready boat to point B return boat and cast second rig to point B
hey presto double the chance of catching fish and double the enjoyment of joining the RC model brigade


WIN WIN

[eddieneil22]

hello,
i did think of a smaller boat,but when iam in france,you want the bait out there with hookbait,and lead in the back of the boat,i can get round the weight issue,ive a long way to go on the build,if it calls for larger motors,thats what i will do,the boat is so buoyant ,even without the plumbing pipes on the sides and back,and with 2 large batteries and 2 kilo of bait,i dont have a worry about that,my only worry will be getting her going,wires, parts  e.t.c
neil

[Netleyned]

If you are going to use your boat in France then be aware that the French 2.4GHz rules
are slightly different.
They have a10mW  output power limit on part of the of the band.
My Spektrum DX6i has a programmable setting for use in France
but I suspect a basic set like the T5 will not.
Gazou who is French and a member on here could possibly
recommend a cheap set for use in France.


Ned

[eddieneil22]

thanks netleyned,
i will be selling the set i have and buy the t5.
neil

[Netleyned]

Neil,
The T5  may not be legal in France.
Some one on here might know.

Ned

[eddieneil22]

thanks ned,
i will ask the question.
