FR7 7 INCH LONG RANGE OPEN SOURCE FRAME

NOW SHIPPING V5.1. READ ABOUT THE CHANGES IN V5 HERE

This open source frame project, FR7, was started by Jeremy Mariscal, a aerospace mechanical engineer by trade and an avid long range FPV pilot. With the help of the community, FR7 has gone through many iterations very quickly and has become one of the hottest 7 inch long range frame out there. 

The FR7 train is here and moving fast. It waits for nobody. BUT, since it's an open source project, getting one's hands on a kit has been less than convenient. We're proud to be the first FPV shop in India to distribute the FR7 frame. The price has been carefully calculated to keep the cost as low as possible. 

DESIGN PHILOSOPHY

The FR7 is a purpose built for fast mid and long range cruising.  Designed to pull clean HD footage without props in view, #NoPropNoCrop, all while throwing a 4Ah+ 6S battery 2-3 miles out and back at 60-70mph.  The FR7 definitely lives up to its namesake, Full Range.

The FR7 combines design features from frames past and present:

• Modified arm geometry (deadcat-ish) keeps the large 7” props out of view in any video format - Project 399 SuperG+
• HD under FPV cam allows for a lower CG and allows for super low perspective HD footage - MB Epic
• Split bottom plate allows the HD cam to be as low as possible - Impulse RC Reverb (and SuperG+):
• Interlocking arms minimized arm movement/slop - Impulse RC Alien
