Engine Performance

Pathetic, sea-level cruising speed is only 219mph while adding the centerline bomb will reduce that to 214mph.  Increasing altitude helps a little though 240mph at 9K is barely worth mention, but speed holds fairly solid up through 20K.  Acceleration feels very sluggish to top speed but not too bad at low speed, especially if you don't have a bomb aboard.  Climb rate is low at 2,300ft/min although that isn't terrible.  Fuel range is a very respectable 82minutes but your total range is still poor considering your low cruise speed.  The Val does have fixed landing gear though so considering the wheels are out dragging in the wind the numbers aren't that surprising.

Firepower

Very light, the Val doesn't really have the means to attack anything or protect itself with guns.  There are a pair of forward mounted 7.7mm guns with 1,000 rounds/gun mounted in the cowling and a single flexibly mounted 7.7mm with 791 rounds that helps protect your tail.  Both are basically hopelessly outclassed in the game.  Even if you manage to get someone in front of you so you can shoot your forward guns, expect them to take a long time to be effective.  To the rear, the most likely avenue for enemy attack, the single 7.7mm is even worse, don't rely on it as any defense and never man it to attempt to defend rather than maneuver.  Of course, this is a dive-bomber though and you would expect a large bombload but that isn't the case.  A centerline mounted 250kg bomb (~510lbs) is reasonably sized but not up to the large load carrying of other aircraft.  You also can load a pair of 50kg bombs on the wings but these are small and only effective against light structures.  There is an interesting dive-bombing sight that can be used to refine your aim although I have yet to figure out how to use it successfully, consistently.

Manueverability

The Val is maneuverable to the point of being insane.  A low speeds, and we are talking VERY low, it can turn like a kite, humiliating some fighters as it flips around the sky.  Even at high speeds, with a caveat or two, it remains totally controllable right through 520+mph.  Roll-rate is always reasonable and the dive performance is quite good although not recommended in a defensive position.  If you are free of bombs then I don't know if anything can actually turn with you other than maybe a Zero, but even it might not be a clear victor.  Collisions and overshoots are always a concern as many aircraft will stall or plow right through a Val at the speeds it typically flies at.  On concern with speed is the fraiglity of the landing gear, with airframe over-stress starting around 425mph and the actual landing gear tearing off at only 480mph.  While having no impact on handling (possibly even improving it), the gear do certiainly offer advantages when landing vs. belly landings.

Flying the Val

Why?  That's the question you should ask yourself before taking a Val out for a spin other than in a scenario.  The firepower it offers is simply so sub-standard that it is not worth the hassle to fly it.  Also, there is a real "easy-kill" mentality in the MA where people will basically suicde to make what they feel is a sure, or important, kill.  Usually a Val will attract as much attention as a perk plane in that fashion.

Offensively, the Val could be used in local defense against vehicles quite effectively or as a light strike aircraft where you have control of the sky.  I wouldn't intend on fighting with a Val in a really tight spot where you are out-numbered.  That said, the Val works as great bait to set people up to be killed by other aircraft which is great fun.  You can use the Val is a decent turn-fighter, it appears to be a significantly tougher than the Zero and seems to turn just as well if not better at very low speeds.  In a stall fight you will humiliate against most aircraft in turn-rate and barely be trying.  Look for overshoots that you can exploit and always watch yourself so you aren't predictable in defense.  You will be using a lot of break turns so be ready to mix up the directions and angles to keep the enemy guessing.  If you can, lock onto someones tail and chip away with the 7.7mm's, you can either scare them off or cause them to crash if they overmaneuver their aircraft.  All of my kills in a Val have been to stalling Spitfires and such who, rather than simply straighten out and run away, instead try to turn just a little harder, lose control and crash.

Defensively, be very alert and throw every strange and unexpected maneuver you can into your defense.  You will be using a lot of break turns to avoid enemies coming from the rear so be good with your timing and make them very sharp and hard.  Slow aircraft are vulnerable if caught un-aware or in slow moving crossing shots.  Those are easy situations so you want to make sure you don't give them up.  The Val is not very tough, it can not take hardly any damage to larger calibre weapons without breaking to pieces.  Nothing, other than maybe a Zero, can out-turn you at low speeds.  Most enemy aircraft will attack, extend, and then re-engage though to avoid any possibility of falling into a trap.  Look for overshoot potential to pounce and strike back with your cowl guns.  If you can, try and enlist a gunner for your rear as the combination of a rear gunner and someone who is maneuvering hard to avoid attacks can be very difficult to beat.  The rear gunner may land some lucky hits and kill, or damage, and enemy fighter.

A few last notes, the Val works well at low altitude, sometimes very low.  The landing gear, because it is always extended, can actually help you in some maneuvers like looping near the ground.  I've had enemy aircraft crash trying to follow my low loops even though my own aircraft brushed the ground but the landing gear bounced me back into the air without damaging my aircraft.  I know, it's a crazy tactic, but sometimes it's things like this that can save your butt and cause the frustration of many enemy pilots who attempt to follow and smack the ground (giving up proximity kills).

Fighting the Val

Don't turn-fight and don't be all that worried about it's offensive potential.  You need to properly predict where it will turn (they always turn) and place your gunsight in that location waiting to intercept them early in their break-turn.  Don't slow down and turn-fight one, it's a losing proposition.  Attack extend even if only a short distance, then re-attack, over and over until you make the kill.  Just try and land some hits, the Val is not tough and can easily be shot to pieces with smaller calibre weapons.  Vertical attacks, like a BnZ, should be almost impossible for a Val to counter unless it can get you looping slowly.  If necessary, use a Head-On, it is unlikely the Val can apply more than token damage to you with it's pathetic cowl guns.

If a Val gets behind you then simply extend, jinking, or roll, just a bit to make the Val have a tougher aiming issue.  That is as much to make the shots miss as to spread them out so they don't concentrate in any one area.  The likelihood of a single bullet critical hit is very remote but you don't want hits to add up in any one area.  Vals tend to be very aggressive as they have few options for retreat so be prepared for them to come right after you if they can.  Quick rolling direction changes can work well as the Val has a large wingspan and momentum is a bit of a problem.

A final thought, usually when something like a Val flys into an area it attracts a lot of attention as everyone knows it is a pretty defenseless kill.  This means a lot of friendly fighters are likely to stop whatever they are doing in order to try and jump the Val and get the kill quickly.  This can lead to a large number of friendly aircraft in close proximity and creates a situation where killshooter is a problem.  Don't get too greedy, watch for other enemies in the area, and leave the Val if it looks like you won't be able to shoot it down before more bogies arrive.
