The air flow is for cooling and it is definitely needed. Some of the components get quite warm. It seems, for the most part, the sticks are the most common problem and I think it's mainly oxidation. ST16's that are used regularly have fewer problems than those which sit on the shelf for long periods of time. That also would explain why new sticks often need cleaned since they may have been sitting in a warehouse for a long time.

It's always a good practice to "stir" the sticks before flying and to also check them in hardware monitor.
@Steve Carr to the rescue again! lol I've been putting the latest replacement H up to make sure it is good to go and hadn't flown my H pro w/ST16+ for a while so I thought I'd check out the controller. J1 was slow. Did the "canned air and stir" a few times and she's back to quick! Thanks Steve!

My typhoon h isn't acting right when flying away from me and really flying back to me. I think the joystick settings are the problem but I don't know how to change it. The J3 joystick indicator looks sluggish, it doesn't look like the other side at all. The return to home works fine, so no recent crashes. Please check out the video attached.

Yes, after spraying the base of the joystick it works fine for a few minutes then it becomes sluggish again.

There are a couple of rubber tabs on the back of the ST16 that you can remove to use some canned air to clean the contacts. It is not a one off procedure. Spray and stir the sticks repeatedly. I had the same problem with one of my controllers and did both the top and bottom numerous times and it resolved the problem without having to disassemble anything.

It just happened to me. Rapid beeping from the H.
I was able to fly the mission, but in a hover the H drifted to the right.
When I checked the stick responses, the aileron was slow & off center.
I sprayed the pot with "CRC QD contact cleaner" through the access hole and worked the stick.
It didn't help right away, but after it sat an hour, I worked the stick some more and that fixed it.

Any ST that has sat around for more then a couple days should get a good stick stirring before you even boot it up. It’s an inherent issue that requires routine checking and maintenance as part of pre flight check. You should also always raise up to a safe hover on first flight and check stick response especially for yaw as that’s usually the first place you find non or slow response in turtle mode. The good news is usually raising the slider toward rabbit gives you back some signal and better control and I’ve stirred the problem out while watching the H dance all around it’s axis during the stick wiggling. It’s not going to go away and will always require the pilot to check it especially if you don’t fly regularly.
