Failure to take-off

[Farmerfurr]

Good morning all, my last post I could not get my ST16 (3 antenna) Screen to come on. Must be something internal, battery is 100% charged. However now after binding to new to me ST16 (2 antenna) I have a failure to take-off. I have calibrated everything twice, made new profile on the ST16, and all it will do is trun the props on, acting like the throttle is disconnected and constantly beeps, green and purple light flashing. However the left stick registers when in the hardware monitor menu. Any help would be greatly appreciated
Thanks
Matt

If it's beeping constantly it's most likely the right stick. If it doesn't return to exactly zero then it won't launch. Check the right stick in Hardware Monitor. Make certain it doesn't look sluggish or erratic. If it does then it will need cleaned.

One of your preflight steps should include rapidly stirring the sticks to help keep them clean.

The Hardware Monitor does not always tell the full story. Please turn on the "Final Output Display" and verify the first channel (CH01) moves when you move the left stick up and down.

The Display is turned on by doing a rapid double tap of the volts Icon:

So in the hardware monitor, J4 does not come back to center how do I calibrate this?

First, try to exercise the stick and spray contact cleaner on the pot. Calibration is a risky thing if the pot has corrosion built up on it.

When the stick is as clean as you can get it, the best two calibration videos are on this page:

Small hint from me: sometimes you need to improve solder joints of the steering stick. Yuneec had some problems with oxidizable solder joints (I hope yopu understand - English is not my native language ) - and in about 70% cases this operation helps. If not - you need to clean or replace steering stick.
