Over the past two decades, we have established an efficient process to create complete STC Kits to provide you, the customer, with the best value. We are so confident in the work we deliver; we guarantee all craftsmanship for the life of the install.

From now until the end of 2019, Honeywell has reduced its exchange pricing. Depending on your aircraft and the part number of your units, Pro Star Aviation can modify your aircraft to meet the ADS-B mandate starting at $65K, in as few as 7 working days.

The exchange program includes:
