WooKong M falling out of the sky!

[srbell]

Set up my voltage monitor for yellow warning only and decent on red. Got the yellow flash and headed back to land, but not before the red light kicked in. Here's the thing, it starts descending at an alarming rate. Way too fast to land. Props are still going and my throttle position is at the top. Gets all wobbly the last 10' and then smacks into the ground. All considered, an ok outcome only breaking three props on my ysixx, but why? I checked the battery which is a Thunderpower G6 2700, only used 2.2ah (these are actually discharging on my computer charger at 3.1ah). My Quantun battery monitor was showing about 3.4v as it hit the ground. Any ideas on what's going on?

I flew with a guy recently that noted in his OSD while flying FPV that after his battery passed 10.4v the voltage dropped very quickly. Remember when you are flying, your battery is under load. After it cools down and you measure voltage it will be higher. When mine does and autonomous landing it does not just fall out of the sky. I would check your settings and try again.

I'll try some new settings. Anyone have some good starting points for voltage settings using a 4 cell pack? I'll set my voltage drop using the Quantum voltage telemetry. Jets are so much easier lol! Run out of kerosene...glide back to the strip and land then install a bigger fuel tank : )

I'd also check your ESC settings to make sure you don't have them reducing voltage or going to a soft run down on low voltage. I had a flip caused by my own stupidity of not checking all the escs.

I had set the esc's to a strait cut off and lowest v cutoff selectable on the programming card. I did run up the battery under load and monitor the individual cell voltages. All were 3.4 except on at 3.03. Maybe that's the cause. One unbalanced cell and my programmed voltage settings in the WK software set too low. Anyhow, any recommendation on the two v alarm settings for the WooKong?

My recommendation is to set a timer and stop using the voltage reg. easy fix.

Mine also drops very quickly when it hits the red light, a bit of a flaw if you ask me. I'd rather it descend slower and risk ruining the battery, than plummeting and ruining the heli. I have to be really quick on the throttle, and I've been lucky so far!

Something else to add to Daves wish list...slow descent!

I wonder if return home on a yellow level would descend at the same rate as descend on red? I'll need to grow a pair today and give it a try lol. Wonder how many times you can smack a Sony Nex5n into the ground before it breaks? I may find out by the end of the day.
