Another update on my before mentioned v2 foil assist.
I gave the body mounted approach a go.
The base of my hip bag is made from neoprene with a PE sheet as stiffener inside. I’m quite happy with the functionality but next time I would go with a kite or wing harness instead of sewing it myself.
The waterproof bag I welded from TPU coated nylon. It closes by wrapping which worked really well. Not a single drop of water inside after 3 extensive swimming/ foiling sessions.
The core of the bag is the CNC miller heatsink which doubles as a rigid base for the cable gland.
For the receiver and BEC I printed this enclosure. After assembly I noticed the remote would not bind. After some tinkering I noticed it must have had to do with the ferrite shielded inductance. Some aluminium foil under the receiver (of course isolated with capton tape) solved the problem. No heating and no more range issues.
The battery is potted only around the poles. A basic guard ensures mechanical protection for the cells.
The mast base is custom milled to fit Indiana aluminium masts. It incorporates some space for a connection of the motor phases which is potted for waterproofing.
For extra safety I added a dyneema leash as second layer of safety. The cable has a neoprene sleeve to make it floating.
Sadly after a lot of work before my vacation the assist did not work as hoped. By now I narrowed the issue down to the motor which was initially a Flipsky 6374. It simply had not enough torque and stalled at 30-40 % throttle. No improvement by changing props, using bigger front wings etc. Therefore I switched back to my old BDUAV 6384. Though I can’t really test here at home.
Jet drive is still not tested in its latest configuration.
