Robin Colbourne Posted May 30, 2024 Share Posted May 30, 2024 (edited) The FlySky FS-i6 is a fairly basic transmitter, however I really don't want anything else right now. I fly a mix of electric glider and IC (internal combustion) powered models and rather than continuously moving the digital trim would like a switch or switches to set three different postiions with an engine. Flight idle - for a steady idle that won't quit in the air Ground idle - that is low enough to stop the model rolling forwards on concrete Engine stop - Stops the enigne ASAP either in emergencey or at the end of the flight The latter I think will work by using Throttle Hold and setting it to 0% In the old days it was easy with mechanical trims, fully forward - flight idle, mid position - ground idle, fully back -engine stop. Has anyone, with either the FlySky FS-i6 or the Turnigy TGY-i6 (its 'badge engineered' brother), managed to achieve what I'm after?

GrumpyGnome Posted May 30, 2024 Share Posted May 30, 2024 I don't, but there are lots of videos on Youtube about setting flight modes modes for drones, controlled by Switch C - a three position switch, which can give you a start................... I think you'll need to liberate the additional channels on the Tx via the firmware update first Quote Link to comment Share on other sites More sharing options...
Jim Hearnden 1 Posted May 30, 2024 Share Posted May 30, 2024 I've always used the trim & ATV. Trim full forward idle (that's safe, e.g. doesn't stop) and idle back to cut. Quote Link to comment Share on other sites More sharing options...
GrumpyGnome Posted May 30, 2024 Share Posted May 30, 2024 Always many ways to skin a cat...... Personally, I always think there should be an instantaneous engine stop, rather than the time it takes to move to minimum trim. 1 Quote Link to comment Share on other sites More sharing options...
Don Fry Posted May 30, 2024 Share Posted May 30, 2024 I don’t use an air throttle/ ground throttle. All glow plug motors, tuned carb, manage with the ground throttle. Then we end up the a two position switch. On or stop. That does all, electric or glow. Additional advantage, when using an electric motor, switch to on, and the motor ticks over, to warn its live. Good for mixed fliers, used to glow motors. so switch to 0 is 0 throttle, switch to 15 to 20%, adjust a necessary, to provide a tick over throttle revs that allows the plane to stand still on the ground.

Engine Doctor Posted May 31, 2024 Share Posted May 31, 2024 Set engine mixture up to give a reliable idle this should be too slow as if engine cools too much then it could quit, especially diesels . Its not difficult then use the trim to make any minor adjustments , Now set your throttle cut so that it will kill the engine reliably. That's really all you all you need . Low speed flying throttle just use the throttle stick. Provided engine is good mechanically with good compression and fuel is good then any engine should idle reliably . Don't forget though that a higher pitch prop can often generate enough thrust to pull a model along at idle so this also needs consideration.

Robin Colbourne Posted July 2, 2024 Author Share Posted July 2, 2024 A quick update. Firstly, thank you everyone who replied with suggestions. In the end I followed What Engine Doctor and I think Don Fry were suggesting. By having two throttle curves, one set to 20 something % and the other to 0 percent for the first point I was able to have a ground idle that I could adjust on the throttle trim and at a flick of Switch D (top left) I could stop the engine instantly as Grumpy Gnome advised and with which I definitely agree. My brother, in Oz, also has an FS-i6, on which he has done the software update. He's better at computer stuff than me, so I'll find out if he can get the three position switch to work as suggested. On the first outing of the Chilli Wind at the weekend (that I bought secondhand at the Popham Show a couple of years ago) the cap of the yellow Ripmax/Anderson fuel tank rurned out to be split, which I hope was the cause of the Evolution Alpha engine dying at higher RPMs in the air. I have now swapped the tank for a SLEC tank and will find out tomorrow if it has cured it. I'm struggling to find out for certain what the capacity of the Evolution Alpha than came with the model. Is it a 40 or a 46? It just says 'α' on the side of the cylinder head. If its a 40, I suspect the model will be underpowered, for a pattern ship anyway. Are there any other Chilli Wind drivers here, and what engine do you use in yours? Quote Link to comment Share on other sites More sharing options...
