Firebird is an US owned and based company since 2017. We are headquartered in Eloy and many of the people here and around the US jump our RUSH or other products with positive feedbacks.
We can name Steve & Sara Curtis, Jason Peters, Sean MacCormac, Andy Malchiodi, Kim Winslow as satisfied users.
The RUSH has a TSO c23D and has no service life limit. Same for other Firebird products
We did realize that the old version was still on our website and the new manual will be uploaded shortly. We apologize for that mistake as we are working on a new website. Every product comes with the new manual on an USB stick, so that actual customers have the latest version.
