Putting the Brakes on
#1
Hi All
I think I've finally found Angle mode and some settings for it. Maybe I don't have it yet, but my Mobula6 and Meteor75 still seem to slide too much after inputs.
Maybe I just don't have them setup correctly yet.
Is there something to adjust to get them to stop better after even very small inputs?
Thanks in advance.

It sounds like you are looking for a response like you find on a camera drone (DJI style). With my DJI quad, when I let go of the sticks, it stops and hovers waiting for the next command.

These quads are not like that. The only way to "brake" is by you using the sticks to apply reverse thrust against the direction you are moving in. There is no setting for making it brake after inputs. This is all part of learning how to control the quad and flying...

What "Angle Mode" does is bring the quad back to level when the control sticks are returned to the center position. It does not change its movement.

A little tip for slowing down. I find that it's much easier to achieve by yawing 90 or 180 degrees first, then giving it some angle, and then finally a little blip of throttle to arrest the motion. Another method is to fly a sharp circle, and I still use this method to lose altitude for a landing.

Here's a quick demo of how to arrest motion.

It's easier to spin 180 and do it, than tip backwards, in angle mode. When you tip backwards, you no longer see what's in front of you and can no longer gauge speed. Spinning 180 allows you to still see the ground, generally and see what sort of momentum you still have.

If you want say position hold, then you need something other than Betaflight. INAV can do it, but you will need GPS and a Baro on the quad as well.

Thanks for the information and tips. I think I'm hurting enough right now trying to keep up with Betaflight and EdgeTX to want to learn INAV also, but the GPS and Barometer seem like they'd do what I think I'm looking for. Any good Whoop size quads with both of those? Maybe I'm looking towards the Cinema type flight more than FPV Racing. With winter in Wisconsin close, most of my flying will be indoors I'm afraid.

If you have a big budget and don't mind the noise, the larger DJI Avata probably has the best position hold and will give you some good cinematic flights/footage as well. Otherwise for a more reasonable budget I think Betafpv has some starter whoops that have optical sensors for position/altitude hold and mellowed down controls out of the box, but I don't imagine they work too well.
If you really want to get into FPV, it might be worth investing the time to learn the more manual acro/angle mode flying as that will open up a lot more options for flying different drones down the road.

Look carefully at the quad to see what is happening when you centre the sticks from pitch and roll in Angle mode and its moving in the direction chosen. I assume that levelling is complete, fast and positive?

If not, angle strength can be adjusted.

Once a freestyle quad is moving, its inertia due weight and momentum will cause slowdown overrun to occur with centered sticks if no other commanded action stops it.

You will soon adapt, and its part of the fun!

Practicing in the sims was the only possible way I learned some of these less-than-intuitive actions.
Now "slamming on my brakes" ie, tipping the quad into producing backwards propulsion and throttling up to arrest motion and then leveling off, comes quickly and has saved my quad from hitting a wall many times(not every time Smile)

Strongly recommend lots of fun sim time!

Haha same on the Sim time.  

I've been trying to learn to spin 180 and 100% arrest momentum, which is fairly easy if you are flying like 10-20mph, but if you are coming in really fast it's harder to gauge the exact amount of thrust to stop dead.  

So far, I haven't hit a wall, nor most anything when out flying.  But I'm super careful.  But I have had a few "soil your pants" level moments when surfing down cliffs and getting just a bit too close to the wall, including one time when I essentially did a throttle punch as I was going down the wall and the ground came upon me very very quickly. Or my first Matty where I pulled out blind and was probably half a metre from the ground, or another time I did a wall bump about 30m up and nudged the lipo out of the strap and then had to fly back with it hanging off the bottom. Tongue When you fly in quarries, with terraces and sketchy conditions, you try and avoid having to go to dangerous places to retrieve quads. Wink

As to Position Hold, I wouldn't bother buying something with it.  Just fly a lot and learn to hover. Maybe buy some parts and build a cine whoop and try putting INAV on it.

I'll tell you right now that a GPS will almost certainly fail on a tinywhoop. I wanted to try that on mine and the EMI from the flight controller was too strong until the GPS was at least an inch away. There's also the need for a magnetometer, which is going to go ballistic in such close proximity to the battery lead and the motors. While there are ways to make it possible, most of them involve making it much heavier than it should be.
