G+_Erik Ellsinger Posted July 10, 2015 Share Posted July 10, 2015 Got my KH250 airbourne now and OH MY GOD THE POWER IS EXPLOSIVE! It's like going into warp drive! But I have one problem, the quad doesn't react when I throttle up until I'm around 40% throttle on the transmitter. This makes it very tricky to fly because it cuts out power very early when I throttle down. Anyone know how I could fix that? Link to comment Share on other sites More sharing options...
G+_Taylor Graham Posted July 10, 2015 Share Posted July 10, 2015 Check what you have set for min throttle on your fc, calibrate your escs, play with throttle curve on your transmitter. Link to comment Share on other sites More sharing options...
G+_Erik Ellsinger Posted July 10, 2015 Author Share Posted July 10, 2015 Where do I find the settings for min throttle in the Flip? Link to comment Share on other sites More sharing options...

G+_Erik Ellsinger Posted July 10, 2015 Author Share Posted July 10, 2015 Seems like min throttle is at what power the motors will start, not when they turn on. I have calibrated my ESC:s but maybe something went wrong, I will try to calibrate them again. Link to comment Share on other sites More sharing options...
G+_Erik Ellsinger Posted July 10, 2015 Author Share Posted July 10, 2015 I tried calibrating my ESC:s again and when I have my reciver directly connected to one ESC the motor reacts when it should react. But when I have everything connected to the FC the motors still react when I have about 40% throttle. Any more suggestions? Link to comment Share on other sites More sharing options...
G+_Taylor Graham Posted July 10, 2015 Share Posted July 10, 2015 I had the exact same problem and it turned out to be my min throttle. I dont know if the flip software has a receiver testing tab, but if it does, check what the value for throttle is when you're at 0 throttle on the TX. For example, on my naze, i think my min throttle on the tx is about 950-980, and i have my min throttle set to 1000. If the flip software has a motor testing tab, calibrate the escs there as well. Play with it. Also, if nothing else works, modify your throttle curve so the motors come on earlier. also, make sure you have your props off! if you set min_throttle incorrectly, your motors could spin up the moment you arm it.

G+_Erik Ellsinger Posted July 10, 2015 Author Share Posted July 10, 2015 I did solve it by setting the throttle curve to start at 10%. I don't know if it's a solution or if it's a workaround. I did some testing with the quad hooked up to my computer. My throttle is at 1090 when there's no input from the transmitter. I have the min throttle set to 1080 and the props doesn't start to turn when I arm it. The props starts to turn when I increase throttle to around 1190. So it all seems to be a bit weird.

G+_Taylor Graham Posted July 10, 2015 Share Posted July 10, 2015 Try something in the middle. Keep playing with it! I'll try to think of what else it might be. The throttle curve thing will work, but its more of a band-aid. Link to comment Share on other sites More sharing options...
G+_Erik Ellsinger Posted July 10, 2015 Author Share Posted July 10, 2015 It seems like, at least on the Flip, that the min throttle is at what power value the engines will spin when they start, not at what throttle value they start to spin. If I set the min throttle to 1000 the barely spin at all when they start. And they do start to spin at a throttle value around 1100. So there should be another setting for what throttle vaule the engines start to spin at but I haven't found such a setting. Link to comment Share on other sites More sharing options...
