Having a 3d printer is a nice thing

my heart always beats faster when receiving new parts 
reduction unit is ready to mount, some electrical parts arrived, I am ready to go for the upper part, where I will be sitting on.
here the pics of the mgm controller:
look at this beauty
it was hard to find a 200A wattmeter for 60V, but I found one
just missing assembly!
i was using the same wattmeter ⌠itâs not easy to read with the sun.
I though that it doesnât matter, as long at i get my max values at the end⌠but i had some breaker issue and basically each time i was getting back to the beach power was off⌠so no data usable.
Start thinking of how you can mount a camera with a good view of it if you want to gather data

The controller does datalogging, very expensive but the all around package is very good. You can see all data afterwards on computer.
a little preassembly:
lot of holes to drill

If thatâs not already your plan, you might want to rotate the full fuselage / wing assembly 180 degree along its axis.
Almost all the weight is transmitted to the front wing. The way it is in you picture, the screws will take the full load. Iâm not concerned about the screw breaking, but the stress on the wing itself will be way more concentrated than if the fuselage was pushing against the wing.
Looks awesome, Board progress and robohand! Keep up the good work.
You will add some fibers to the wing, correct?
Looking forward to see it on the water
@Mat yes the front wing is upside down, whole tube must be rotated 180°. Backwing isnât screwed or glued yet, otherwise I couldnât make a picture, backwing would fall down 
@Hiorth I honestly think that the frontwing would brake, this is why I will print it again with a hole going nearly through the whole wing to screw a rod in for stiffness. I donât like to work with fiberglass, itâs messy and dirty^^
Donât misunderstand me, PETG is very strong, I couldnât brake it by hand yet, but the bending is pretty high and I think it would cause âaerodynamicalâ flow problems 
And i will shorten the alutube, now itâs 750mm, will cut it down to 625mm.
Mast is cut down to 600mm too as you guys recommended.

Could this hand be a waterproof remote? The remotes look so goofy in-hand. Why not make the waterproof remote part of a glove / 3d printed hand of some sort?
