Standard Electronics include:

R-832 M two-band radio
SPU-9 crew intercom
RKL-41 ADF
RV-5 radio altimeter
MRP-56 P/S marker beacon receiver
RSBN-5S navigation and landing system
GNS430 (optional, paid addon) *

* It's not really worth it, unless maybe it's on sale or you want it that badly, as it lacks a lot of functionality (I guess it's ok for DCS but it'd be nice if they improved it). Like the Mi-8, C-101 and perhaps others by now, the GNS430 addon is implemented naturally into the cockpit of the L-39C (when the game option is selected to remove its gunsight, which also provides a nicer view).

The L-39ZA is not affected and the GNS430 is not implemented as part of its cockpit, its gunsight is kept no matter what and this seems to make sense, it's the more heavily armed version anyway. The gun sight assembly can be removed out of the L-39C anyway, the option to remove it (with the Editor or whatever) is not part of the GNS 430 addon.

GS-23L 23 mm twin-barrel cannon
