better to use a laser printer the inks are not water soluble

Metal to metal noise on 2.4 mhz by Haverlock Admiral   Posted: 1 month ago
2.4GHz seems to be pretty resistant to "noise" that affected 40mHz 35MHz and 27MHz HOWEVER its a good idea not to push your luck and try to minimise such effects.

Plans for a V8 engine by Haverlock Admiral   Posted: 1 month ago A little work and you can mock up an engine top only £3:50

Plans for a V8 engine by Haverlock Admiral   Posted: 1 month ago
well there are these its a sort of complete engine

Plans for a V8 engine by Haverlock Admiral   Posted: 1 month ago
I don't know what your looking for exactly but have you looked at the add ons made for the car builders some RC cars are 1/10scale and they do a whole host of bits. A quick search brought this up

H2O Engine by Haverlock Admiral   Posted: 1 month ago
I am left on awe of your work. However your water engine does have exhaust its water! that's why it fills up. Every time you draw in the oxygen hydrogen mix then result of the explosion is water and if you do not figure out how to get rid of it ( feeding back to the reservoir?) your cylinder will eventually fill and you will shudder to a halt.

Wiring in a rx, an ESC and a battery (pack) by Haverlock Admiral   Posted: 1 month ago
first take a deep breath and calm down its not rocket science. Question does your ESC have a battery eliminator ? if so take away the dry batteries to use in something else. Now your nicads connect to the POWER side of the esc. make sure you have the correct polarity. The servo plug from the ESC plugs into your receiver whichever is your throttle channel. If you have a modern set then you can put it on the wrong way round with no worries since positive is the centre post. The output of the ESC connect to your motor. If its a brushed motor no need to worry about polarity for now. With your ESC there should be some setup instructions if there are none ...... Usually its connect and switch on receiver then switch transmitter on with throttle full listen for beeps then go to low throttle. Switch receiver off. When you switch on in future make sure transmitter is switched on FIRST ok having gotten this far it only remains to check the direction of rotation of the motor. Take off the prop ( saves fingers) and put a piece of masking tale around end of prop shaft. Switch on transmitter switch on receiver and try the throttle. If the motor spins in correct direction fine if not Brushed motor swap the motor leads over Brushless motor swap any 2 of the 3 motor leads over. Job done have a cuppa then decide to sort out the rudder.

Model Shipwright magazine by Haverlock Admiral   Posted: 1 month ago I do not know if that's any help but worth a look anyhow

Brushless motor and ESC by Haverlock Admiral   Posted: 2 months ago
if you have a look here there is a selection of motors esc intended for high speed models.

Futaba antenna by Haverlock Admiral   Posted: 2 months ago
So long as the new antenna length is the same as the old no problem. You can cut the wire and replace with a length of piano ( music ) wire if you wish ( glue a bead on the end eye protection). The big no no is to coil the length up.

autonamy by Haverlock Admiral   Posted: 2 months ago
For anyone else who finds the idea interesting there is a publication called arduino robotics and has a chapter on building and programming an autonomous craft.

Battery problems by Haverlock Admiral   Posted: 2 months ago
A quick check on the specs of your motor /esc combo states its good up to 5s LiPo. So step 1 get a watt meter ( cheaper than burned out motors ) Step 2 check with your bank manager ( or wife) for available funds Step 3 buy the biggest 4s or 5s LiPo you can fit in the available space. you will also need a LiPo charger do not attempt to skimp on that step LiPo batteries need special handling and can be spectacular if you do it wrong. You have not mentioned the prop your using if you use the watt meter you can play around with different props so the current used by your setup heads towards the point you pick twixt performance / running time. If you do go LiPo you will also need a battery monitor part of the careful handing includes not discharging them below around 3.3 Volts per cell. 3s =3cells 4s=4cells etc. So if you go 4s then you should not discharge below 13.2V. some text on the care and feeding of LiPo batteries. The reason for your problem is a simple case of battery chemistry a lead acid accumulator cannot deliver a high current for extended periods gasses on the plates prevent the electrolyte coming in contact so the battery loses power. After a while the gasses are re dissolved and the battery can then go on providing power. Nothing wrong with the battery its just a case of wrong tool for the job.

Glue guns by Haverlock Admiral   Posted: 2 months ago
I have used them and still do on occasions in my experience I would never trust a joint made with one that has to stand any stress. If you just want to stick something decorative down its ok. If on the other hand you need to be sure the joint will hold use something else. The more porous the item to be glued the better hot glue will hold it. Yes the glue joint is waterproof BUT its perfectly possible for water to get under ( capillary action) a joint on a smooth surface and cause a joint to fail. By now you have probably gathered I am not a fan. Oh and if you do use one watch out the glue is hot enough to cause a burn and it sticks to skin fine.

Proboat Volere by Haverlock Admiral   Posted: 3 months ago
if your going to play with props get a watt meter that way you can use your test tank ( bath) to get some idea of the current draw. Way cheaper than a new motor. If you can get inside the boat consider change of motor and esc. ( and go lipo)

Proboat Volere by Haverlock Admiral   Posted: 3 months ago
I did a little searching and found this if its the same boat then it would seem there may be a problem with your setups

Soldering 1/12 Scale Brass Railings by Haverlock Admiral   Posted: 4 months ago Tin/lead solder is still out there and I agree with Dave not being a fan of lead free solders

Soldering 1/12 Scale Brass Railings by Haverlock Admiral   Posted: 4 months ago
First take a deep breath and calm down. Soldering is easy if your only using 2mm material I would get a reel of 60/40 cored solder. Use a decent sized electric soldering iron. Clean all your joints well ( use a fine abrasive like 600 wet and dry). Apply the iron to the joint then apply the solder remove solder remove iron. You made a joint repeat until you have done. Try not to burn yourself. Clean any flux with meths and an abrasive.

Handed props by Haverlock Admiral   Posted: 4 months ago
its a little safer to take props off and put a piece of masking tape over the ends of the prop shafts. That way you can check rotation directions and keep a full set of fingers ~laughs~

getting old by Haverlock Admiral   Posted: 5 months ago
getting old is a state of mind and my mind is in a state

Anchor Chain by Haverlock Admiral   Posted: 5 months ago
You can use Liver of Sulphur (Hepar Sulphuris). Used to be available at the pharmacy. It will darken/blacken silver, copper and brass.

the important thing about Westbourne models is to stop mentioning them ! 😜

Aerokits Fast Patrol Launch stern cover by Haverlock Admiral   Posted: 5 months ago
if all else fails you could use some Neodymium magnets they will hold it in place.

raf crash tender by Haverlock Admiral   Posted: 6 months ago
within reason you are not limited to LiPo batteries. My reasons for pointing you in their direction are their ability to supply current for lower weights. I am not expert in their usage having only playing with them for a short time BUT once you take the plunge they are like everything else use some common sense and they are fine. Charging requires a LiPo charger That's the kind I use ( will charge nimh nicad and lead acid also) as to batteries some is good more is better ~laughs~ Its a case of run times at the current dumping your using I have some 5500Mah 3s ( nominal 12v ) lipo you can link batteries in parallel to get increased runtimes. One important thing to remember is not to run a LiPo down to too low a voltage the limit us usually given as 3.3v per cell so a 3s will give you a 9.9 v low point. IN practice aim for a higher cut off voltage. Depending on your radio setup ( I use frsky ) you may be able to have your battery voltages echoed to your transmitter. The charger will charge to full and also charge to storage voltages LiPo batteries must not be stored at full charge. Probably there is a lot more you need to know Dave M is way more expert than I.

raf crash tender by Haverlock Admiral   Posted: 6 months ago
Consider going brushless mechanically the motors are simpler ( no brushes) and they are more efficient. If you take the plunge and use LIPO batteries you can have any amount of performance. Not sure but I think an 800Kv outrunner would give you all the power you need and no gearbox needed. The torpedo motor has a recommended rating of Operating Voltage 12 volts. Current approx. 5.28A at max efficiency. RPM at 12.0v - 4289 at max efficiency. Weight 595g (approx) Shaft Diameter - 6.35mm The 800Kv has a 28A rating at 12 V so a wattmeter and a bit of fiddling you can match prop to motor and get some performance

Engine Sound Effects by Haverlock Admiral   Posted: 7 months ago
audacity is a cross platform sound editor so I should think there is a version for mac computers. Bluetooth speakers are cheap enough and come with amps built in sounds can be recorded and used as a playlist on a smart phone you can get a Bluetooth extender to increase range this is all off the shelf tech and you probably have a smartphone already

Paint types by Haverlock Admiral   Posted: 7 months ago
Two pack epoxy is the toughest!! It largely depends upon many factors what are you going to be doing with it. For a scale gently handled model acrylic is fine for something to be handled roughly then enamel ( or cellulose ( if you can find it)). Just remember that the surface your painting on counts cellulose onto enamel will "pickle" acrylic you can paint onto just about any finish. Seal it all with an acrylic varnish.

Kingfisher Plans by Haverlock Admiral   Posted: 7 months ago
You could add an extra piece BUT consider your prop will still be at risk. The speed of the prop is a vector addition of the rotational speed plus boat speed. Unless you intend to run at very high speed its probable the shaft will survive most collisions.

Propeller 101 by Haverlock Admiral   Posted: 7 months ago
Do not forget to specify right or left handed the thread is the same but the direction of rotation is different and please do remember to fit a locknut ( and use locktite) so your new prop doesn't join the rest of the lost bits on the bottom of the pond

Esc brushless by Haverlock Admiral   Posted: 7 months ago
No promises BUT a quick search turned up this :- at £28 plus post it would probably be cheaper to buy a new ESC

Esc brushless by Haverlock Admiral   Posted: 7 months ago
It depends upon your ESC most of them are forwards only BUT Esc(s) for cars and boats have reverse ( usually). Also quite a few have the ability to be programmed so you can have either on one Esc. We need the model number and maker of your Esc before we can even begin to be more specific.
