Can do.. kinda defeats the purpose but you can fly what you want - no natter to me. I will update the tours to include the MD530 for you. Won't take me too long to update them.
Now FYI:
Anyone can custom add your aircraft of choice right in Cigar Box for any flight or tour leg.
1) Load the flight or tour flight into Cigar Box,
2) Scroll to your aircraft selection in the Aircraft Information box > Select the aircraft then select "Load and your aircraft of choice will be added as the aircraft for that flight.
Done. (See pics attached)
