This lake is next to our workshop, the problem is that there is a lot of algae.That’s why the falls!We must go to the open water!
After drying, the remote worked!
Check all seven times for water resistance
Hi!Finally we are on the wing!!!
Charging without leaving the water!
Hi everyone today I want to tell you how we solved the problem of water-cooled ESC cooling without water.Since we already had an aluminum plate made for the old ESC, we didn’t want to add water cooling.We removed the lid and cut a copper bar to the size of the camera.And the roughness of the bottom was leveled with a heat-conducting paste mixed with copper filings.And fixed the ESC on an aluminum plate!
The temperature during the tests on the water did not rise above 30 degrees!
Hi!Today was not in vain!We made some useful measurements.Weighed your Board!32 kg!!A lot!
We also tested the thrust at 40% power with various screws.The 7-inch screw gave a thrust of 30kg.5 inches 40 kgThe 7-inch screw must be cut off.Make it smaller in diameter!And with a thrust of 35 kg, the battery consumption was 35 amps!
We also measured the minimum exit speed to the wing. It turned out to be 15-17 km/h.But comfortable skiing is 22-25 km/h.Wing area 1400!
