Have been testing the ZOHD Nano Talon slope soaring without the prop. We did a weight test yesterday. At a flight weight of 590 grams it flew just fine slope soaring in about 25knots of wind. This was 70 grams heavier than the flight weight with the 1500mAh 4S and the FPV gear. (Runcam eagle rpo 2, BEC, eachine ATX03) which clocked in at 520grams.
