thank you david great help

unsinkable 2 my advice look for a previous build and do a build thread..... when you get stuck ( which you probably will ask here )

also good tip I got when it starts to "go wrong" walk away and come back another day... things always seem better later

lastly try and end your days work  on a high   :-))

I'll go along with that Mike.

Isn't it strange that when you return the next day, the answer is staring you in the face.  How come we didn't think of last night.    :}

cheers

Hiya.

The battery connections to the motor can be connected either way, depending on rotation direction required..

The battery can placed into a polythene bag and secured with an elastic band...

Hope this helps

Balloons are a good way to cover electrics you don't want getting wet you can even fill the neck around the exiting wires with silicone to produce an almost submersible unit....... maybe  :D

I'm a beginner too and I've been researching rudder linkages; I think I'm going to go with some piano wire with a kink in it to absorb shock and allow for some small adjustments.

You can use the threaded rod and quicklinks here http://www.slecuk.com/balsa-wood/Control-Fittings.html
or use the ball links as an alternative to quicklinks http://www.slecuk.com/balsa-wood/Ball-Links.html

thanks jim got the links

now more questions

how to bend balsa

plan is to put shaped balsa around the top edge of boat

so best way to bend.... I gather heat but best of way of getting heat bear in mind painted black




next question bottom spray rail .... how far round the boat does spray rail go.... ie starting from front does it go towards bottom of boat and stop or carry along the bottom edge of boat to the back



picture of someone elses spray rails on pilot boat would help me out here

lastly what size bullet connectors ( male ) do I need to fit the esc to motor wires as in my pic







hope you don't mind these easy questions for some but you are all a great help

thanks mike

   Hi,
       Try immersing the wood in boiling water then gradually bend it to the shape you need, tape it to the hull and leave it for 24 hours then see how much curve has been lost. If required more boiling water, its much easier to do before the paint though. Good luck.
       Cheers,
           Faz. :-)) :-)) :-)) :-)) :-)) :-)) :-))

Hi Mike, the boats looking good judging by the earlier photos :-))  but I can't get my head around how your motor turns but your prop doesn't! Do you mean it turns then stops or never turns in the first place?


If it turns and stops then it could be the shaft needs lubricant IE it's getting warm, expanding and temporarily seizing up whilst the motor continues. (Binding)


If it never turns in the first place then try and get some photos of your setup and I'm sure with all the members on the forum that someone will notice something. Then you can sort it. Good luck let us know how you get on........ U2

I just saw the earlier photo and notice that you have the same red universal joints as me. There is a small Allen grub screw in each of the brass 'nuts' in each end of the joints (I'm sure you're aware :} ) but what I did was to drill a slight indentation in the shaft so when tightened the grub screw can't spin on the shaft. I then cut a small groove on the surface of the shaft that lines up with the indentation so I can find it once covered with the brass nut. It's just about visible in this photo.....

thanks for that, never noticed grub screw ... not even sure if there is one there, shaft is well lubricated

prop turns, then locks

so think grub screws are missing

Mike.....I assume it is the overall height of each stanchion.....from deck level to top wire

I changed the link to 4o mm.. so thinking a 3 hole stanchion @ 40 mm between each wire would actually be 3 x 40 = 120 mm from deck to top wire  %%

I would have guessed 40mm is the overall height, but could well be wrong (again!).
There's no mention of the hole diameter for the rails, either. A short e-mail to Model Boat Bits should sort everything out.

When it comes to the 15mm measurement it is the overall height of the stanchion excluding the bit that sticks into the deck, the distance between balls varies and you have to depend on the picture that the supplier provides to see how the balls are laid out, in your case I'm guessing that they are evenly spaced or otherwise it would specify that they are different.

Raflaunches is correct....... Just to clear things up here is a 30mm stanchion

Hi Mike.

Having looked at your video,  I noticed the coupling is close up to the motor.  It might be a good idea to slide the coupling out a fraction to prevent  it rubbing the motor housing and allow for expansion.

Hope this helps,

well big lesson learned silicone sealant is hopeless

disaster on the boat

boat was leaking so tried sealant around the prop on inside, still leaked, took all sealant off and used thinners and propshaft fell out

so now have hull with hole in bottom where propshaft enters  and it leaks presuming around prop and rudder



need advice

resin first ? with tape sealng hole, seal around propshaft first and with what ?

give up and try another boat  {-)

Right then pin your ears back young Sir  {-) {-) {-) .......leave the propshaft and motor coupled up making sure that it is perfectly aligned....use masking tape to hold it central....once HAPPY put a few drops of superglue around it to hold it in place.........on the outside of the boat tape the hole up being CAREFUL not to knock the shaft loose....when you have done this work now on the inside of the hull.....Make a well around the shaft with some scrap pieces of 10mm x 10 or similar to create a box around it....now fill this up with an Epoxy glue...allow to set ...remove tape and you should now have a shaft that is watertight....apply filler to smooth out the area around the shaft and paint as needed ....do the same with the rudder.....if your other boat has the shaft held in with silicone sealant then simply do the same
