 The most common Arduino ATmega board with more than 64 kB of flash memory is Arduino Mega. To use it with ArduinoOTA library, you can't use it directly with the Arduino AVR package, because the package doesn't have the right fuse settings for Mega with Optiboot. You can download [my boards definitions](https://github.com/jandrassy/my_boards) and use it [to burn](https://arduino.stackexchange.com/questions/473/how-do-i-burn-the-bootloader) the modified Optiboot and to upload sketches to your Mega over USB and over network.
