[NSRCA-discussion] Braking question

[David Harmon]

Hi John….could be but the OS 1100HV and Futaba MC 9100A work great without screeching or any other operational problems.

The brake is very effective and I have had the brake setting adjusted between 50 and 90 on various 2 and 3 blade props as large as a Mejzlik 22 x 12 2 blade and Mejzlik and Falcon 3 blades.

The hand held ‘loader’ is small enough to put into the transmitter case and you can make quick changes at the field between flights without a computer or other hardware.

Both ESC are clones to each other…they look exactly alike except for the mfgrs sticker.

The loader is also clone across both mfgrs and operationally are exactly alike….in fact I have only one loader and use it on both ESC.

All available at RC Japan….tower does not have them anymore because they said sales was too slow…arrgh

I am using the Plettenberg Advance motors at 15 degrees timing.

The reason this is so touchy BTW is because you guys are using sensor-less brushless motors. Commutation takes place in the speed control. This works fairly well when the speed controller is driving the motor. When it’s the other way around however – not so much. I bet if someone came out with a motor that had position sensors and a really expensive speed controller to drive it, more people would get  interested in Pattern again… LOL

This is exactly my experience as well.

ESC dependent. Castle ESC braking doesn't work well over 30% in my experience, without screeching. I set my OS controller at 65%, and it works fine. Jason goes as high as 90% with an OS. Some other controllers don't work well with braking at all, such as the YEP controllers from HobbyKing.
