I've been reading about the MD-550 motor in the shaheed. The joke of 'DEPLOY THE LSAs TO DEFEAT THE STEALTH FIGHTER' was funny, but it did make me wonder 'how the fuck are they so good at making these'?
The 'lawnmower engine' meme is copium. The Iranian drone manufacturers (and the chinese and russian factories that make the same engines) are amazingly advanced. I'd actually be scared if I was Israel. These are precision munitions with software defined radio and firmware that is updated daily in response to intelligence, being produced in the tens of thousands.
