firstly I’d like to thank Pacific meister for setting up this community and secondly Silvio on which my set-up is based.
My build is not yet finished yet, just want to share and i’m open for suggestions
After my chinese friends weren’t able to send me a PLE40 replica after 2 months waiting, I descided to swich to a setup similar to Silvio:
Motor: AquaStar 4084 620KV : https://hobbyking.com/nl_nl/turnigy-aquastar-4084-620kv-water-cooled-brushless-motor.html -> i will run this on 12c.
Gearbox: Reisenauer Motor Chief 6/1, incl flange 4-P-CHIEF-Flansch PEGGY : https://www.reisenauer.de/aid-251-MOTOR-CHIEF-6-1-br-mit-Alu-Konus-Stahl-M10-br-o-h-n-e-Assorter.html
Custom printed part:
(v2 is with duct)
Batteries: 2x6s Multistar 10000mAh (want to double the capacity as soon as everything works)
ESC: flier boat 320A : https://www.aliexpress.com/item/Flier-new-version-12S-320A-brushless-ESC-for-RC-boat/32750220880.html?spm=a2g0s.9042322.214.171.124024c4dDBFr6e
honestly I think this is overkill now I switched to the 4084 instead of the 56114 motor. Would it be a problem?
Board: I build my own, PIR foam+3 layers of glass epoxy
My plan is mount the aluminium mast mount by 4 screws in the mast, and fill it with superfix 009 to make it waterproof and to give it strength. I will glue the motor as well.
I also plan to put the superfix 009 between the motor and the motorflange to waterproof.
I estimated worst case 35kg of thrust in axial direction, and the same in radial(in case i hit something). I called Reisenauer to ask if a axial and radial bearing is needed. He almost started laughing; the reisenauer motor chief can handle forces up to 50kg in forward, backward and sideward directions
So the bearing I already installed is not really needed, guess I leave it in there anyway.
I made a groove in the red printed part, in which I placed a rubber ring. This will be comressed by 4 bolts. The ‘legs’ of the printed part are 1mm shorter to make sure the rubber ring is compressed well. In the printed part, I will place a double lip seal.: https://www.amazon.de/dp/B01GEACKUC/ref=pe_3044161_189395811_TE_SCE_3p_dp_1
I put 2 wooden beams underneath which i epoxyd in the foam.
On the bottom and topside I epoxied a plate of 20x30x5mm carbon to give strength to the bolts
Last week I tried the foil behind our boat, it was surprisingly easy! I have no surf experience but i managed to stand a few minutes. Take of speed should be ±14kmh (our boat speed is 12kmh, so I could only come out of the water when making a corner)
electronic box, still have to organize and waterproof the connections…
I see some people use a forklift relais, what would be the benefit from that from what I use?
I have one question:
I can programm my ESC. Do you have suggestions about my settings?
Im especially curious about the max power:
My motor is 10C and I have 12C. Now I read that this motor can handle 12C, especially as my motor is cooled very well. But would it be wise to cut the power a little bit(say to 85%?)
Thanks and I’ll keep you updated! b.r. from Utrecht
