I think we need a new MRVI now that we have thruster damage.

Personally MRVI 3 is my favourite for looks but functionally MRVI 4 is probably the best choice for a dogfight. I would say you should look to develop a small carrier to transport them.

hopefully MRVI 05 addresses your concerns B. Iron Kawaii Tager (Cutest)

As for the rest of you I need help. Which one do you think I should develop further?
Personally I prefer number 4 but what do you guys/girls think?
also new name?

Good maneuverability and good weapon placement. The earlier designs' cockpit is too far out of any armor protection that I would say it's maneuverability does not make up for it (though I do enjoy the MRVI3). I like the weapons and design that's gone into the MRVI4, but the cockpit is exposed from the top. Perhaps adding more gyroscopes to improve up-down motion so you can always turn with the belly of the craft facing the opponent?

I was unaware of this flaw, thankyou for making it known

Great job, it stands up much better in dog fighting. the only flaw with the first ships was a single well placed shot took out the codpit instantly, this one works a treat.

Added heavy variant as per Kelly's request
is it 'beefy' enough? :)

These are fantastic fighters, very fast and nimble, would love a more beefy version

Thanks for adding it!
