Day 2: Close to the ground

Posted 06-04-2008 at 06:34 PM by alfasilin

Today I worked out flying by video glasses close to the ground. I went to the field early in the morning to prevent the wind blowing my mini trex away. The major problem flying close to the ground was the radio control range. I am using JR R700 as receiver, and this device has very simple PPM processing that cannot filter out the glitches caused by the poor reception. Actually its decoder is a 4017 counter and simple timing circuit.. Really prone to glitches..

Because of this I flew the bird close to me.. I am planning to replace the receiver with Berg 7 which claims to have better sensitivity and noise rejection algorithms.
