hello I just made my first efoil flight (200-300m, first turns) on my first DIY efoil, (flipsky VESC 75200, flispky 65161 motor 120KV, fliteboard propeller, lipo 6S turnigy 20A in serie= 12S 20A, foil gong curve LT 1500cm², stab kite 45 , gong mast V1 80cm, board: gong zuma 6.6 120L), but I find the lateral stability (in roll axis) very destabilizing and difficult to manage, with the impression of having a left/right oscillation all the time. (yet I am an experienced foiler, 5 years of kite foiling, 1 year of wingfoil, + dock start).
could this be due to a V1 gong mast that is too flexible? or maybe the board too long (Gong Zuma 6.6 120L)?
The good news is that my first diy efoil is flying well with only 1100W in flight mode, and 2200W to get it flying. (my weight 70kg)
Thank you for your wise advice
