In every fighter to fighter scenario, one has to destroy the other plane to be successful. This much is given. With the 110 though, it seems that opportunities and options are far fewer than with other fighters in every situation. It has great firepower as main strength but gets far fewer opportunities to use this firepower. This means that the pilot must be an expert marksman because he is unlikely to get more than one chance. And be able to do it at non-optimal ranges (meaning often at longer ranges or at difficult deflection situations).
Head to head mergings, bouncing, some energy tactics, flaps and slowing down so much that the enemy hopefully swings past, giving a moment to use the firepower as they fly/climb/run away in a way that other aircraft cannot (except P-3
do.
The firepower package in the nose is always awesome. 4xmg17 with infinite ammo, 2xMG-FF, or MG-151's with 2xMk 108 30mm cannons. It has the range and ability to reach out and touch people far, far away. All the weapons are fairly equal at longer ranges because the heavier the cannon is, even if it has lower and lower muzzle velocity, does not slow down as much in flight, and catches up with and even overtakes the lighter shells/rounds after a few hundred meters (beyond most people's effective gun range). The MG17's lose most of their power beyond several hundred meters however and as such are not good looong range weapons. Their superior speed is better for hitting stuff very close, and no-convergence means no problem shooting at too close of a range.
If relying on the plane's firepower, and posessing very(!) good gunnery skills, having an external gunpod could even be a good idea. Because if gunnery skills are so good, then aim will be on target - but the RPM of say, two cannons, is low enough that the enemy plane, especially if a small fighter flying straight at or straight away, will be able to fly 'between' the shells. The gunpod can double the amount of shells in the air in the same spot bringing double the potential damage and higher likelyhood of a hit (I'm talking long range here, not up close).
110's should excel in the role of being the 'bag' when it comes to "drag and bag" tactics. Get enemy to chase a friendly plane, then 110 shoots the enemy being dragged by the friendly.
So I think.. that I need to focus on my gunnery much more than acrobatics (which I am decent at after practicing mostly that for too long). So how does one make use of the Revi gunsight fully? Those rings are there for a reason. It was made so the pilot can estimate range to target and lead. Very important, especially at longer ranges. And especially easy if they are flying straight (trying to run away) since the effective gun range is much longer than other aircraft, but the aircraft flies away quickly, the moment is fleeting.
Revi gunsights were in most Luftwaffe aircraft back then. There must be manuals and guides for how to use them. I have the official USA gunnery manual from 1942 or so, and while it teaches about gunnery principles, the data is useless as it is all in one of those old arcane systems of measurement that were/are still in use by a few percent of the world. And the sights they used do not have the same properties as the Revi gunsights either. Need real Revi guides.
