Just a guess. I have no idea how to make a mortar shell nor how to aim it accurately. For a drone I just tape some explosives to it and then fly it remotely via camera to the exact thing I want to blow up. I probably don't know enough about it but it seems like something I could do right now. Just go down to the local electronics or camera store, buy a drone. Not sure where I get the explosives. |

However it's quite possible and indeed not that hard to build a long range, autonomous RC plane. You just need to use the sensors typically found in any smartphone: GPS, camera (for ground imaging), accelerometer, magnetometer and so on, add inexpensive barometers and ultrasound or optical sensors for altitude, and mix all that up with the proper algorithms to end up with really accurate positioning. In fact you can even have accurate positioning when losing GPS.
If you're not concerned about speed, a simple and cheap powered model sailplane made of styrofoam could easily be made to fly for hours on battery. Cost: a few hundred dollars worth of parts.
