The Kraken
is using dt750s.
I asked about what was a recommended power setup for it, and josh linked the DT750's.
No clue why he is using 25A esc's though. The DT750 max amp is 18A , and that needs a 11 inch prop.
Using a 10x4.3 you should get 14-15A at full throttle.
Iv build a "mini" 130% kraken myself, free handing the motor positions and using the dt750's.
It was noseheavy so my 3000 mAh battery pack is behind the spar instead of in front of it.
The strange noises is from running simonk reversable firmware in my esc's. At certain throttle/ruder levels it will reverse one motor. This resulted in some strange behavior though so i'm going to revert do normal simonk.
Unfortunately i botched a launch when i was testing out 8x4.3 props on it and crashed. Just didn't have the power to get out out of the stall.
I now need to replace my motor shafts, and rebuild one of the motor pods.
So iv removed the openlrs rx and boscam vtx from it for now and i intend to move that over to the bixler 2.
