Is rc curve what is called "expo" ?

The link that oyvinia posted in the previous message is very useful though. It shows clearly the relationship between all the three settings and shows the resulting control curve. The way that curve looks defines how your quad will respond to your stick inputs and you'll find a similar curve and settings in other firmware. If you want me to explain how the shape of the curve actually affects the controls, just shout! • Posts: 947 Threads: 66 Likes Received: 350 in 248 posts Likes Given: 164 Joined: Apr 2016 Reputation: 34 The kiss rates are similar to betaflight rates in theory, but feels slightly different: Rates is rates Rc rates is similar to super expo Rc curve is the same as expo Posts: 2,286 Threads: 38 Likes Received: 1,527 in 995 posts Likes Given: 1,881 Joined: Apr 2016 Reputation: 72 (12-Apr-2017, 02:18 PM)oyvinla Wrote: The kiss rates are similar to betaflight rates in theory, but feels slightly different: Rates is rates Rc rates is similar to super expo Rc curve is the same as expo What do you reckon? Is the KISS stuff worth the money? I've stayed away from closed source stuff what with me being a coder for my day job. • Posts: 947 Threads: 66 Likes Received: 350 in 248 posts Likes Given: 164 Joined: Apr 2016 Reputation: 34 12-Apr-2017, 04:27 PM (This post was last modified: 12-Apr-2017, 04:28 PM by oyvinla.) I think kiss feels smoother than betaflight and prefer kiss over betaflight. When we are talking about differences, I really like how raceflight one feels also. It is very smooth, but also sharp. It is a bit hard to explain, but IMO, they both feel better than betaflight. I was a big betaflight fan untill I built a kiss quad Posts: 106 Threads: 22 Likes Received: 24 in 20 posts Likes Given: 7 Joined: Jan 2017 Reputation: 0 Thank you both very much for your help !

I was a big betaflight fan untill I built a kiss quad Thanks. I guess I'll have to give KISS a try on a future build then! I won't use Raceflight though, no matter how good people say it is. • Posts: 106 Threads: 22 Likes Received: 24 in 20 posts Likes Given: 7 Joined: Jan 2017 Reputation: 0 What is raceflight ?

I was a big betaflight fan untill I built a kiss quad Betaflight feel is VERY dependent on your settings, I tend to drop D setpoint weight to get that smoother feeling even before the maiden flight. But it still feels inconsistent between the builds. And its defaults change even more between releases. |
