Proximity (Hall effect) sensor wiring by Haverlock Fleet Admiral!   Posted: 10 days ago
While I accept you had that in mind not everyone would realise the situation. Stating the obvious needs to be done on occasions.

Proximity (Hall effect) sensor wiring by Haverlock Fleet Admiral!   Posted: 10 days ago
switching off and on via the ESC switch does NOT disconnect the battery from the ESC just stops the ESC passing current. Power is still being used. The only way to end all current flow is to disconnect the batter by either opening the pos or neg lead from the battery. Mounting the magnet on the end of a screw and having that fit into a threaded hole should deal with the problem of keeping it in place while running.

Proximity (Hall effect) sensor wiring by Haverlock Fleet Admiral!   Posted: 10 days ago
I do not know how much knowledge of electronics your friend has but I need to point out that a hall effect sensor is not like a relay. While they do act like a switch ( sort of) they need to be powered and have a hall effect voltage to switch. This would mean in the use intended there would be a current drain on the sensor and if the power supply ( battery?) voltage fell to far it would not function. The effect you want could be replaced by a reed relay cheap and simple to use. However reed relays can only pass low currents so would need to be cascaded with a higher rated relay before switching the main battery supply on and off. https://www.ebay.co.uk/itm/10-Pcs-2-5X14mm-3-Pin-4W-Glass-Re... these reed relays have both normally open and normally closed contacts and at a couple of quid for 10 worth buying so he can experiment.

gas shot off by Haverlock Fleet Admiral!   Posted: 14 days ago
as a first thought if you have a spare channel on your transmitter use it to drive a servo to close a shut off valve it could also function as a valve to prevent accidental gas leakage when connecting everything up. Trying to do it auto is fraught with danger since even if your out of water your still going to have pressure. If on the other hand your wanting to stop the gas if your pressure falls to low why?

All hooked up, nowt happens... by Haverlock Fleet Admiral!   Posted: 25 days ago
first question which no one seems to have mentioned is :- did you have the transmitter switched on BEFORE you powered up the receiver/ esc ? If not de power the receiver and try switching on the transmitter . Most of these systems have an interlock to prevent the motor running if there is no transmitter.

Equipment wire by Haverlock Fleet Admiral!   Posted: 1 month ago
Have a look for intruder alarm wire comes in 4 and 6 core and is stranded as opposed to solid wire which a lot of the telephone wire was ( dunno if it still is) https://www.ebay.co.uk/itm/Alarm-Cable-6-Core-White-Intruder... if you need thinner still ( and unless the wire is supported VERY well I advise against it ) use wire wrapping wire. https://www.ebay.co.uk/itm/0-25mm-Wire-Wrapping-Wire-30AWG-C... hope this helps

Is there a way to...? by Haverlock Fleet Admiral!   Posted: 1 month ago
the short answer is YES! however it may be a little more difficult than your willing to undertake I guess you want to allow some one to select full throttle but have limited speed. Depending on your transmitter you may be able to have dual rates on throttle. if not read this article its a walk through on retro fitting dual rates on throttle. https://www.instructables.com/id/Add-dual-rates-to-a-channel...

Transfers by Haverlock Fleet Admiral!   Posted: 1 month ago
https://www.ebay.co.uk/bhp/laser-decal-paper My point was and is using an inkjet requires you to seal the printed item before water slide since inkjet ink tends to be water soluble while laser printer ink is not so its one step saved. obviously once in place on a model it needs to have a protective layer of something.

Transfers by Haverlock Fleet Admiral!   Posted: 1 month ago
its even better if you can get a hold of a laser printer since the "ink" is waterproof so no need to varnish before doing the waterslide.

Brushless motors (again) by Haverlock Fleet Admiral!   Posted: 1 month ago
This looks like a BEAST https://www.rapidrcmodels.com/ntm--4248-650kv-v2-brushless-o... run it on a 4s battery ( ok go 5s and a smaller prop)

Brushless motors (again) by Haverlock Fleet Admiral!   Posted: 1 month ago
depending upon the type of motor cooling it can be a problem. Most brushless motors are out runners so the case rotates! In runners are usually for higher speed applications (or driving a gearbox). If you have an idea as to the size of IC engine the boat was intended to have then this list may be a help .049 or .051 = 100 watts 0.10 = 200 watts 0.15 = 300 watts 0.25 = 500 watts 0.32 = 640 watts 0.40 = 800 watts 0.45 = 900 watts 0.51 = 1020 watts 0.61 = 1220 watts 0.75 = 1500 watts 0.91 = 1820 watts Since Watts are Volts * Amps ( I know this is not accurate for a reactive load like an electric motor but its a rule of thumb) This gives you a ball park next point is the KV ( revs per volt) of a motor. The higher the KV the smaller the prop. Finally buy a Watt meter they are not expensive and give you a chance to " fine tune" a setup. https://www.ebay.co.uk/itm/FT08-RC-150A-Hight-Precision-Watt... Car ESCs ( usually) have a reverse function while the airplane versions do not. They are generally cheaper than boat specific ESCs.

Your ideas on how to stabilize a flat-bottomed freighter. by Haverlock Fleet Admiral!   Posted: 2 months ago
you could consider using some of the modern tech and fitting active stabilizers there are a lot of cheap solid state gyros and if your receiver does not have enough free inputs and outputs an arduino mini could handle the logic.

Painting by Haverlock Fleet Admiral!   Posted: 2 months ago
rather than making odd leg callipers head down to W H Smith and pick up a helix drawing set. It includes a fitting so you can clamp a pen fits the spring bows

Sail cloth by Haverlock Fleet Admiral!   Posted: 2 months ago
may be of no use to you but I did find this https://www.sussex-model-centre.co.uk/materials/covering/nyl... obviously its intended for covering an airplane BUT have a look and make up your mind.

RC....mixers? And other unknowns.. by Haverlock Fleet Admiral!   Posted: 2 months ago
I recently tried 2 ESC(s) into one battery connection then into 2 channels of the radio. Received wisdom said that one of the red leads to the radio should be disconnected. This I tried and one ESC ceased to function. So to prevent unwanted feeding on the positive lead from one ESC to another I fitted a diode to each of the ESCs. If you were to do the same I think your setup would work. However if your TX has mixing capability then why not use that ability to mix rudder with the 2 outboard motors so you have the added steering of the 2 outer motors? Any how fit the diodes please this should prevent the ESCs damaging each other its a simple job https://www.ebay.co.uk/itm/20x-1N4007-rectifier-diodes-DO41-... 20 diodes for £1 the silver band is positive so goes towards receiver plug.

LED Tug Mast Navigation Lights by Haverlock Fleet Admiral!   Posted: 2 months ago
if your still thinking about the cabin light you may like to think about using a surface mounted LED https://www.ebay.co.uk/itm/Surface-Mounted-LEDs-10-Pack-Choo... Just to give you an idea

the Olfa cutter is a compass cutter https://www.fredaldous.co.uk/products/olfa-compass-cutter?ut... you can avoid the pinprick by using a covering piece to take the point of the cutter. I did however pick up a compass cutter from https://www.theworks.co.uk/?q=Circle%20Cutter This has a covering piece to stop making holes in the work piece.

Do you NEED insurance to fly a model airplane no. Should you have it YES. Its not very long ago a teenager was killed in Dartford. https://www.telegraph.co.uk/news/uknews/1447013/Girl-14-kill... You may take the position that this was a large(ish) model yours will be smaller. While I cannot locate a reff. I have a memory of a story relating to a child killed by a .049 powered model. This was many years ago. Your idea of a foamy probably being to light to do much harm sounds good until you consider how much mass it holds in ballast. Remember the energy of a moving object is given by 1/2 MV^2. If you have a flying site which is remote from other people and privately owned so there are no members of the public around then again your probably good to go. If however there are chances of other members of the public around then its foolish to take a risk which is not needed.

before you use RS to buy your wrapping wire you might like to look here https://www.ebay.co.uk/itm/0-25mm-30AWG-Insulated-Silver-Pla... I didn't realise anyone was still making wire wrapping supplies.

I know people build real jets I look at them and DROOOOOOOOOL. However at my age and short pockets looking is about all I can afford. When it comes to stabilising I have a pixhawk in my quadcopter and that is an amazing beast. It is capable of autonomous flight following GPS waypoints then auto landing.

reading the rc advisor I found one point VERY strange he states in runners still have brushes ???? All together children " OH no they don't" I had forgotten the ducted fan use however yes ducted fans with a need for high RPM and less torque in runners are the obvious choice.

Spektrum, new, useless... by Haverlock Fleet Admiral!   Posted: 5 months ago
and yet another in runner in a boat https://www.youtube.com/watch?v=4e69u7VKQP8 on 8 cells!

Spektrum, new, useless... by Haverlock Fleet Admiral!   Posted: 5 months ago
in runners get used in the model car crowd other than that they are used in FAST boats. As with most things its a trade off in runners lower torque but more revs ( for any given wattage ) match the prop to the motor and your going faster with an in runner. https://www.youtube.com/watch?v=I4hU7Rv7X2w one example!

Spektrum, new, useless... by Haverlock Fleet Admiral!   Posted: 5 months ago
sorry but most flying crash test models use outrunners. The lack of torque of an inrunner means you have to use a very small diameter prop ( I am generalising ) so unless your going for an all out speed model use an outrunner. http://lmmac.net/i-c-to-electric-conversion-table/ As you can see an outrunner is shown as the representative motor. https://www.cmfhobbies.com/IC-Engine-to-Electric-motor-conve... Again generally out runners.
