I have been working with Rainbow Air for almost 4 years now. I instructed there for 1 of those years. The owner is as dirty as they come. He takes pleasure in intimidating students to get paid in full by halting their flying. He is being investigated by several government agencies for fraud, theft, labor violations, and even smuggling. I only write this because I have been questioned over and over by several authorities regarding these allegations.
Beware, Rainbow Air will take your money, promise you an amazing deal, and then provide NOTHING. They sold most of his fleet to pay for outstanding bills after being taken to court and then charges his students for fueling the aircraft they already pre-payed for.
Please stay far away from this dirty scam artist. You will regret trusting anything he promises.
