Simple Smoke Generator
I haven't deliberately tested to destruction, but I have abused the heating coil during development. On the whole, I have tried to keep the coil operating conditions as close to the normal use as an e-cig, i.e. wick wet with smoke fluid and an air flow over the wick/coil. To reduce the risk of the wick running dry, I expanded the smoker fluid storage by adding a reservoir tank to the original e-cig reservoir. The new tank is made from acrylic tube I had in my 'useful bits' box. It is important that the reservoir is airtight, otherwise the wick floods. The filler hole is closed off with a caphead screw and o-ring. JBkiwi has recently demonstrated a refillable reservoir with a pump to keep it topped up.
I'm sure that without fluid, the coil will heat up more, and would, if it gets hot enough burn out. That will depend on how much current is being passed through it. I have let some of mine run dry without failure. The e-cig housing does get warm, but not too hot to handle. I assume this is also the case when used for it's original intended purpose. So not so hot that it would cause a fire, unless the current is set too high, in which case the coil would likely burn out quickly removing any risk of fire.
There are different coils available, with different electrical characteristics. The ones I am using draw a current of around 1A on 3V. I make sure that any electronic drivers I am using have a current rating way in excess of that, so haven't had any failures due to the coil running dry or burning out.
For the gunfire simulation I do run the coil continuously with no air flow for much of the time. That way there is plenty of smoke to blow out of the e-cig when the air pump is switched on. I haven't had any coil failures with this. The only coil I have destroyed occurred when I accidentally applied a fully charged 2S LiPo direct to a coil. It vapourised within milliseconds!

Flysky TH9X with OpenTX and AFHDS-2A
Thanks for your answer, yes, I was binding the devices several times, and I agree with you, just changing the module everything should work, but the reality is that the new combination didn’t work, even testing a lot of different communications setups in the transmitter, may be the old operating system is able to handle that but not the open tx, but as far as I know somebody has this combination working

Aerokits 1962 34.5" RAF Crash Tender rebuild, including interior.
This is a boat completely developed by me, it's not a reproduction of any other vessel, I was designing every parts and adding them to the boat, it's a floating laboratory, in this case the alternate name is Sealab 002, now it's still under construction, once finished will be an RC boat, with a lot of diferent remotelly controlled groups of lights, video camera and video recorder controlled from the transmitter, and also it will have temperature and battery monitoring, confirmation of RC signals, alarm protocol in the case of signal loss, bluetooth or ESPNOW external monitoring of signals and so, by the moment it's the second of a laboratory boats series, the scale is 1/72

Springer Tug with fibreglass hull and plastic card deck. The rest of the build I have done on 3D printer using the easy cad part programme just as a fun project to see what could be done on a 3D printer by a beginner.
The Shottel drives I bought and are driven by speed 600 motors, also I bought the 19mm bow thruster. The lights are all working remote using a quad switch from Action Electronics the spotlights can move on mountings and lens are removable for lamp replacement, with the rear flashing beacons coming on when the winch is selected using the aux channel.
The engine sound generator works from the throttle channel and the horn operates on the gear switch. As I have only one loudspeaker fitted below the winch platform the gear switch for the horn also energises a relay which transfers the loudspeaker signal from engine to horn.
Speed controllers are fitted to bow thruster and winch motors.
There is also a photo sensor on the front which brings on the flashing light on wheelhouse roof when a object is within 150mm from it(ie boat to be pushed).
The names on side and rear are all 3D printed letters not transfers. And the wheelhouse roof is held on with magnets for easy replacement of lamps or resistors.
I have also fitted with two receivers to work from either of my two transmitters for convenience if a rescue is required, while I am sailing with one transmitter then I can use the other. This is easily selected by use of double pole three position slide switch.
Apologies for photos being a bit mixed up.

Billings 1/40 USCG 44 foot lifeboat
Model built from Billings kit, single 18mm brushless motor, 10 amp ESC, stock prop. Haven’t weighed her yet but I’m thinking in the neighborhood of 8 to 10 ounces ready to run, with battery. Motor is a little hot for the hull type, I have to keep her no more than a little over half throttle or she tries to torque over, but she makes good speed at that. Really needs a motor about 1200 kv or so, the current unit is closer to 2000.
I built her as a lark, to see if I could make something that small run reliably and be fun to run, and I think I succeeded, from what I’ve learned on this boat I can apply to other smaller models and plastic static kit conversions of roughly the same size.

Dragon Flite DF95 (Yacht)
The DF95 yacht by Joysway is a great introduction into sailing a racing yacht. Easy to sail, not too expensive compared to IOM's and 36R's and you can change the rigs in about 5 minutes as the weather dictates. The standard A Rig supplied is perfectly acceptable for a lot of wind ranges on an inland lake but you may need to change down to a B rig if you sail in exposed locations. There is a great racing scene around the country and internationally as DF 95's in their own special class. I had the opportunity to sail mine in very high winds last Sunday (01 Feb) and had some fantastic sailing especially on the downwind legs where it was 'flying' but not submarining. (10/10)
