Went out testing yesterday morning aiming to tune the drift code, but it was a complete mess. I can’t fully explain why, but certainly one factor was the battery and raspberry pi were slipping around in flight, despite being firmly attached with velcro and either none slip padding (for the battery) or non-slip feet (for the Raspberry Pi). The problem was the moisture still in the air after the morning mist cleared.
So I’ve improved the velcro, made better fitting non-slip padding for the battery, and added double sided sticky tape to hold the Raspberry Pi down, and I’ll try again later today.
It’s hardly worth blogging about this, other than to point out how well attached to the quad frame all the loose pieces must be if you stand any chance of consistent test flights.
