Hard to imagine they could improve the 2014 version of the EFX Racer but seems they have done it with increased internal capacity to take up to 6S (if you change up to 80A ESC), full wing spars, FPV ready, slope soaring nose cone, props for 3S and 4S power etc. Fitted mine out with a RunCam FPV Eagle cam which proved to be excellent for anyone who wore the FatSharks on my 2 flights. I'm thinking a cam with OSD and artificial horizon would of great benefit to the pilot actually flying this pocket rocket on FPV. I'll do that soon.
