Hi there,
I'm kind of fresh to all this stuff, but I was wondering if there is a way to automatically release the bomb, with some sort of timed mechanism somehow. Without using radio commands.
I'm setting up an aircraft glider.
Any ideas would be appreciated.

Is this a radio control glider?

There are battery powered timers and solenoids that could probably do this. But, before going too far, you should contact the British Model Flying Association http://www.bmfa.org to be sure there are no regulations against it.

Thank you for your suggestions,
No, it is not radio controlled and I'm not building like a proper big model aircraft.

Could you please specify what it is exactly I would need, to go about building this. I have a good enough budget.
And/Or any online stores that supply such products.

i don't know if we should even be helping you, you seem suspicious at the moment
