Hi, can anyone give me some guidance regarding my project? i have a x-cell gasser heli 700mm, all the info that i have found on the forums/google etc. all point to a flybarless electric heli which doesnt have throttle controls, where as i require a throttle control linked with pitch control,
any guides etc will be appreciated, please be advised, i have no coding experinced at all on arduino.
I just wish i had more time to learn the code to be able to provide some or more support to the product.
Randy, you still in the US? It's awful late in Toyko!
Malcolm basically explained it. With a gas heli, you need a 3 (or more) point throttle curve controlled by the Tx. Similar to an ESC without a gov function. So, just a standard setup you're used to.
It's easy to get an ESC with a Gov built in, I'm using a Turnigy K-Force 40A on my 450, it was $28 and has a gov function that works well, and a 100A Superbrain on my 600 with a gov function.
Unfortunately for gassers, you need a stand alone governor that goes between the Rx and Servo. They're about $200?
thanx guys, the feedback has provided more info into my build.
Robert, im quite interested in the arduino governor you are working on, as hopefully it could provide feedback via the telemetry systems
One of the purposes of my heli build is to be used in a search & rescue out at sea where due to circumstances rtl is always changing so the heli would need to be given commands via MP where to RTL. wind and weather conditions change continuously here off the south african north coast.
My opinion, but you will have big problems with what you are trying to do. You would need either a twin-motor helicopter, or a hex or octocopter. Otherwise, motor power loss (it happens) will result in loss of the helicopter. You cannot RTL with a helicopter when the motor fails. The best you can hope for is a soft landing wherever you are. But if you're over water...
