This is the updated version of the Skyventure-300; the "Skyventure-300I". The "I" stands for instrumentation. in addition, this version boasts better power and stability with a slightly larger prop and wing angles, particularly in the horizontal stabilizers. AG1 starts the engine and prop, AG2 the Nav lights, AG3 the strobes, AG4 the landing lights, and AG5 the interior lighting. Switches are setup on the dash for 6 and 7 though I have not assigned them as of yet. The model has other additions to detail as well. A step for getting in and out of the cockpit, places to illustrate where the gas would be added to the wings, a sump location below, panels for engine inspection, and cargo doors to the rear of the fuselage. If I update again, I'll post it as quickly as I can. Definitely check back often for new models.
