...with the I-15bis or POLIKARPOV_I15_tipo2 1939 by xavierb. The download plane has 1000 rounds of mg ammo ( 7.62 mm (0.30 in)PV-1 or ShKAS machine guns) and 2000 rounds for cannon! I should be armed with four 7.62 mm (0.30 in)PV-1 or ShKAS machine guns, plus up to 150 kg (330 lb) of bombs.

The section of the dp (I think) looks like:

Also the later variant the I-153 or POLIKARPOV_I153_VVS by xavirb has 2 mgs and 2 20mm cannon but again 1000/2000 rounds!

Any help with these would be greatly appreciated. A dp tutorial would be nice. I remember seeing one on line once upon a time...
