The Diatone Roma f4 LR is the most recent full release in the new category of 4 inch micro long range quadcopters following on from releases by Flywoo, Iflight, GepRC and Eachine. It is available in a version with the DJI Caddx Vista and a cheaper version with analogue video Basic specs are similar to the others but I'll get into the detail in this review which separates the good from the great.
The 4 inch micro long range market is well established now with a solid Formula that has been developed by the very clever Dave Cledon (his youtube channel is here). In this review I am looking at Diatone's offering - the Roma F4 LR of which mine is equipped with the DJI-Caddx vista and Nebula V2 camera although most findings will be applicable to the analogue version as well. Diatone have always had great attention to detail including a solid tune (as I found recently with the larger Roma F5 here) so keen to see how this translates on the F4 LR.
