To be fair, that's 1 in every 6, and the US used them for armed recon and light attack work (strafing) in the MTO. I can't recall if they were called F4s or F5s or what, but essentially the same plane with a camera mounted behind the pilot's headrest and a bubbled for the lense to look out.
On the one hand, I wouldn't want to see them abused as badly as I bet they would be. On the other hand, I bet folks that generally would HO and run wouldn't get too far because of the atrocious performance. It would be like a P-40 with cannons. Sure, it's got the cannons, but so does a typthie/tempest!
If HTC ever gets the perked ord working, and we get the A-36/Mustang Mk.I, I'd like to see the 50cal option and then a slightly perked 20mm option. It would have its uses, including taking towns down.
Out of curiousity, anybody know how much ammo they stored per gun? The C-hog has craploads of ammo, but the british planes tend to be really conservative. It's a US plane, but built for the RAF, so I wonder whether it leans to the light ammo load or the heavy ammo load.
