I just saw the two comments in question and find it to be absolutely hilarious.

A serious answer to your question - no, these are in the "whoop" weight-class. Warhead carrying drones for anti-personnel and anti-armor are usually 10 inch and up, meaning they are using "10 inch" frames and likely 3115 motors, with 6S battery packs. Of course, there's endless variation, but that seems to be a optimum combination

Ukrainians and Russians use 7" drones for dropping grenades and suicide charges. This does not seem too far off?

Whoops and 7" drones are pretty far apart (depending on what you consider "far", I guess). Whoops can barely lift their own weight, 7" drones can carry maybe a kilo.

A 7” drone can happily carry about 1.5kg which is more than sufficient to carry a RPG shell.

Most RPG warheads are pretty heavy.

Maybe he was just looking for people that agree with him?

I find it hilarious to think that this was just an honest question and we downvoted him unfairly.
