How's the proportional break work? Doesn't allow the prop to free wheel and maintains a constant rpm I assume?
Aside of the geared/outrunner power, the problem I have with the outrunners is what do you do if you should have a problem. From what I can tell they're all sold through retailers that don't have the facilities to handle repair work. Not all problems have to do with the gear boxes.
Did you see any of the cyclons in France, observations?
Hi rm
From what I understand its basically the same software they use for RC electric cars. So at a point on the throttle stick the motor will start to resist being turned (I dont understand how this actually works) the more you move the stick back the more breaking force you get. It makes a huge difference in the air and has the potential to give more breaking than needed on downlines, its very obvious once you see it in action
Again its a new way of flying and will take a bit of getting used to as now the idle of the stick actually does something! I wont say it maintains a constant RPM, but it signficantly reduces the windmilling that you get with the electrics. The energy removed during the breaking process is fed back into the packs, about 50 mA a flight I understand
I dont know about repairing the outrunners in North America. Plett will repair them but they are in Germany. With that said I have not experienced a failure of any kind in ~400 flights. The biggest thing to watch for in the outrunners is temperature because they are so short they can be tough to cool.
Yes Cyclon was there in France, however none were being used in the competition so I was only able to physically look at the motor itself. The setup that JP from ZN is running with his is a 20x13 prop, about 6500 RPM and pulling 75A with TP 5300 packs. With those numbers my intial thoughts are that the motors are not as efficient as they claim.
