Sunset session was cut short, literally
Have the maytech as a backup.
Surf was incredible, glassy and bigger than this morning.
Some nice waves despite short session.

High risks ok reward (drone shots)
Had to pick up the drone from the air while on the water as battery was done and could not connect again with my phone to bring it to shore.
Great footage. Glad you saved the drone!
3 day weekend done, total 6 batteries in 5 sessions.
had 2 runs with the paddle, much harder then what I expected to handle remote+ apply andy human power on the paddle.
Last session got 22 starts on 1 battery, with the maytech wich is slighlty less efficient than the 6384.
That is very encouraging, 20+ starts is enough for some good downinds, more than double what I can get with the 24 lt.
Session with the drone had the best waves, crossed path with another guy on a mid lenght and FD assit slim, he was having a blast but had trouble catching waves, in learing process/.
only used the 1401 for one session, then 1201 all the way. Really improved my carving and “wave” reading. On the assist side, I had this wire snap on the 6384 on a crash where the mast mount must have moved, then I broke a few blades during handling, storage in the car.
The signal was perfect, sure external antenna does not look as nice as other solutions, but it works and is simple.
The cheap latches are showing some rust spots. The pogo seems fine as long as I use plenty of grease, foam seal is doing his job to keep water out of them. Latest (3rd) battery is perfectly balanced
The DIY board works well, but at 19,5" / 50 cm wide it is not so stable (I will adapt) and the nose shape could be better to handle touchdowns. I dont have comparison points of similar boards. The weight is
Glad to have made the most out of this time at sea, as I will ge a shoulder surgery in december, then it is 3 months out, maybe can start pumping by +45 days.
That will leave me a lot of time to prepare for season 2.5
made a similar 160mm blade as the printed one, but thinner, to be made in forged carbon. Mold is being worked on now, will be printed first, in 3 parts :
bottom mold in 2 parts (blue) and insert to press on the carbon fibre (green)
mold
for future reference :
10gr of chopped fibers according to 60% fiber content and mold volume
14gr of A epoxy
8gr of B epoxy
Mold in PLA, covered in a thick coat of candle wax
ref : Forged Carbon Fibre Mould Design and Strength Optimisation - Easy Composites
verdict tomorow
Resin must have been cold/wet, not hardening as expected. Now in the oven at 50°C
Edit : got the part out of the mold, the mold got zero damage, there is some flashing to clean.
Demolding was fine with candle wax
Now the part in in the oven at 80° for a few hours
After more curing and some light sanding.
Resin let me down but the concept is validated, looking forward to try again with good resin (sicomin).
Be sure to use a digital scale to measure your resin. In small quantity like that its not possible to eyeball it in a cup.
Had it by the gram on a kitchen scale, but for such small QTY the error factor could be big (wetting the paper cup, tare on the scale, protect film on the scale)
I use volume by syringe for the small quantities, and the minimum mix I do is 10+3.5ml. This way the percentage of mismatch in the mix is almost removed.
A great tip is that the r&g epoxy bottles have holes that exactly matches the syringe, no extra pour cups needed, no risk for spilling - and they also sell replacement caps.
Yes also a good way for really small batches for sure. Nothing worse than a bad mix that is gummy and of course not even close to expected strength.
Make a mold off the Foil Drive prop blades.
If you have the 3d as a step, I could try. This is based of the similar 160mm b series prop as the one I am successfully using on 12s with 6384 and maytech, but thinner to increase efficiency.
Those caps are an excellent idea. I have used them give my dog her meds with syringe as you describe. good tip.
I fill two part canisters and use mixing dispensers for creating small mix volumes of silicon, epoxy etc
Made a second one with sicomin époxy, by volume using 30+15ml of resins.
I made sure the resin was RT before mixing, and let it cure in the hot closet overnight.
The part I got out is much better, feels super strong and has the sound of a fully dense and cured part.
Demolding was harder but the mold is still usable.
Nice, this looks very good!
I’m currently experimenting with the same process as I’ve had few failures with my casted polyurethane blades!
The carbon seems plenty strong!
For people interested to try, here is the mold, added the locating features.
Needs 4x 100mm M5 bolts and M5 nuts
