Brushless lift motor control.

(1/2) > >>

Netleyned:

A mate of mine has built a hovercraft with a brushless lift motor.
He wanted to control it with the fifth chan switch on his Planet T5.
Is there a way of switching a brushless esc to full ahead without
using an analogue control?

I am building a Hover so will be interested in the answers.

The fifth channel switch on the T5 can be set for a slow transition from position one to position two, look under the little hatch on the RH side. Would this be enough, as it would provide a steady inflation of the skirt, as the motor spools up to full power. Setting up your speed control on this switch may b e interesting though.
I do not know of a method of controlling brushless without the input of a speed control, which would be best controlled via a proportional channel on a radio. Short of using a servo driver manually of course, a bit backwards that option...

Netleyned:
Would have thought a brushless esc
needed a zero to full ahead progressively.
A brushed motor could be switched off to on
easily.
 The question is do the airy fairies have any
on/off switching for brushless?

Subculture:
You can go from zero to full on with a brushless esc if you choose. The esc handles all the start up routine anyway. Some esc's will have a throttle curve built in, that tends to be there more for the car boys to preserve gearboxes etc.
