In planning paper(試製震電　計画説明書　S19/8/7 九州飛行機株式会社), it is written that weapon for J7W1 is 17shi(type5)30mmX4. And for training J7W1 can install two 7.7mm and Guncamera at nose.

Each cannon has 60bullets(I.J.N Interceptor Fighters by Sigeru Nohara).

Spec of 17shi30mm-1gata-otsu(Type5) is

Muzzle Velocity: 750 m/s
Rate of Fire: 350 rpm
Weight: 70 kg
Length: 2.192 m
(this is from 航空機用大口径機銃計画用目標 s17/8(1942) so TimTam27's info will be adopted. )

But my model dosen't have cannon at nose, because My 3Dmodel is flight test condition which you can watch at the movie.

Maybe armed version is next step and I have not decided what cannon I use for 17shi30mm yet.
