Throttle Stick Mid Postion. Sprung vs Un-sprung

Started this discussion. Last reply by James Apr 9, 2016. 2 Replies

I wonder what the general consensus is for what people now use and prefer for the throttle stick and whether to have it spring loaded so that it sits in the middle (hover position) compared to having…Continue

We see a lot of assumptions out there about props etc, but very hard to find hard evidence and factual data. The data I have been searching for over the last 6 months is to find proof whether Carbon…Continue

ZeroUav YS-X6 maiden flight with very impresive rock solid stability and amazing RTL

Posted on December 13, 2012 at 5:30pm 0 Comments

The return to home on the YS-X6 is very impressive and particularly how stable it touches down and then turns the motors off.  Even in full manual mode the copter hardly wanders at all.

The main down side of this ZeroUav system is user manual is absolutely appalling and virtually useless. Also the  GCS for PC is not very intuitive at all. The…

If you have a housing that is covering over all of your electronics such as a plastic container,.. then when you descend or ascend quickly the pressure inside the container changes and gives your barometer an false reading.

For example if you descend quickly the pressure increases inside…
