Castle ESC's break records, my entries.
Over the past few years my father and I have been breaking records. Most of our records are electric based planes. Nearly all our tests and most of our records have used our trusty castle creations esc's either on the record day or in one of our tests.
We also have a new high altitude plane that uses a CC 80 esc and will be able to go to altitudes of 18000 ft, (that is as hight as the faa will let us go without yelling at us!) It has 17,500 mah of lipos (2500x3s7p) and has a flight time of more than 2 hours at a low power cruise. It uses a Kontronik 480-33 geared 5.2:1 with a 12x8 prop. This setup id 90% efficient (measured)
The distance plane is bigger and heavier and has if I remember, 36,000 mah of li-ion round cells(4s15p), as when we did our research they had the most watts per pound. We have not tried it, but it should be able to fly over 4 hours under power. It has an Actro cl-8 14x12apc, not the best, but light and it works.
Below is a list of all our electric based records.
We used it for the record and it worked great, but it is still not as efficient as the kontronik jazz 55.

Here are some frame grabs from the altitude plane.
