Hopefully gaijin is still working on the Ka-Chi because it still has problems that need to be fixed (some have already been talked about in this thread)

Incorrect side armor

gun depression and elevation is incorrect should be the same as Chi-He

gun depression is locked to a few degrees when pontoons are equipped when it should only have its depression restricted when aiming over the front or rear pontoon

one of the wheels is missing weathering effects (like rust and dirt)

fuel tanks are don't have individual damage model (destroying one of the fuel tanks leads to the loss of all fuel tanks on the side which lost a fuel tank)

pontoons should act more like 8mm armor not 4mm as the round should be passing though 2 4mm plates (the front and back armor plates of the pontoon)

Arty rounds hitting the pontoons can cause a overpressure kill

Let's hope the Ka-Chi won't meet the same fate of the Ki102..... being broken and inaccurate for 5 years.

From Japanese wiki

Well, apparently the verticle guidance of the Ka-Chi is copied from the Ka-Mi which is weird because both vehicles have completely different turret and gun.

And also the +24 degree of elevation is strange, no other tanks have such elevation. and just like the Ka-Chi the gun is clipping through the turret ring on the Ka-Mi aswell

According to a book detailing the 47 mm Type 1 tank gun:

"The first battle of the Type 97 medium tank equipped with this tank gun was the Battle of the Philippines at the beginning of the Pacific War, and was used in all fronts until the end of the war. In addition, the Type 1 medium tank (Chi-He), an improved version of the tank, and the Special Type 3 motorboat (Ka-Chi) manufactured for the Navy were also equipped with this tank gun. The elevation angle of this tank gun was -15 to +20 degrees."
