After some improvements, "Yellow" had to be tested on Tankumsee test track. It performed well, though water was a bit bumpy an "Yellow" has been in the air for some time. Power is extreme, so I had to be very careful with the trigger. Battery was 4 cells lipo, It can run with 5 too, but 4 is far enough. Whole System remained cool without water cooling. New water drain vent performed well, too. Acceleration is extreme, reaching high speed in 1 or 2 seconds, it's almost jumping out from water - very cool

One engine only: Keda KB36 8s. Speed control water cooled. 10 cells 3800 maH. 3-blade prop.

That's my technical mock up in an old victory 700 ep boat to test the new motors.

The victory 700 from my son. A little bit unstable in curves due to missing turn fins and usage of 2 parallel rudders, but not bad and with bright headlights :-)

That's my fastest victory up to now
