On all programmable radios I've seen, there's an option for a throttle hold. This differs from a throttle cut slightly in it's used to keep the throttle at a minimum setting. A nitro engine needs a throttle cut to kill the motor and the throttle hold makes sure that you can't bump the throttle while it's idling and send it off across the field.
On electrics, it's really easy to bump the throttle as well. Especially while setting your plane down or carrying it after plugging in the battery or testing the controls. Any time you aren't ready to throttle it up it's a good idea to have the throttle hold turned on.
I have personally bled from bumping the throttle on my hobbyzone supercub while taking pictures of the aileron throws after doing the wing mods. My brother bumped his controller and his 450 helicopter spun up in his hands and took off. Neither of us are new to the hobby and we both learned the hard way.
Take it from me, find out if you have the capability and program yourself a throttle hold and use it.
