I don’t think I’ll invest in a V1. If the only real problem is that learning on it is more difficult and will simply take longer, then I’ll keep working on it and eventually I’ll get it figured out. 
I have another question regarding the FR propeller. @Jezza, I saw your post where you managed to reach 38 km/h with the same propeller, a 120 kV motor and 12S.
Obviously, I know that this also depends heavily on the foil itself, rider weight, riding skills, etc.
I’m wondering whether it actually makes sense for me to move to 14S with my current setup. I see two main advantages of staying with 12S. First, safety, lower voltage in the water. Second, I designed my battery packs to be easily removable, so I can swap them for larger packs and also use the same batteries in another project.
The other project is a 4WD platform with four brushed 24 V motors. My idea was to use two 6S packs in series for the efoil, and then, once removed from the efoil, connect the same packs in parallel for the vehicle. It’s basically a multifunctional ~100 kg platform on quad-bike wheels, which currently uses standard lead-acid batteries.
So, do you think moving from 12S to 14S would actually make sense in my configuration? Is there a realistic chance of getting a proportional increase in top speed, or is the FR propeller likely to have some kind of practical speed limit where increasing voltage won’t help much anymore?
