Decided to build my first ever pneumatically operated prop this year and after some research and calls to several retailers I decided to order from FrightProps. They answered my many, many questions politely and with clear authority on the subject, never sounding impatient. My orders (FrightProps crew instilled such confidence in me that I ended up building two pneumatic props and needed more items) were shipped promptly and arrived on time or earlier. I had more questions after recieving the parts and every time I was met with the same courteous experienced assistance no matter who answered the phone. Thier help allowed me to build two great props this year. They have a lifetime customer in me.
