Quote from: teslahed on Tuesday,June 11, 2013, 01:55:33 The NanoWii is just a small well designed multiwii board. It will handle any multirotor any other multiwii board will fly - it';s not just for smaller quads.

Quote from: JT on Sunday,July 07, 2013, 08:21:36 Very cool, you are getting really good at those flips and rolls The rolls do look slower but it may be that the camera can always see the horizon so it just gives that impression? Your quad looks very agile in the turns too.
Quote from: nub on Sunday,July 07, 2013, 12:07:51 u should start trying to do 1/4, 1/2 turn pauses in your flips, also slow the flip down and give it some throttle for some big ass loops i prefer to flip forward for some reason, if it coming at me backwards, it seems more a habit from my heli flying think it just depends on the momentum u have wither u need to punch the throttle a little before flipping IMO, like what i said above, when i do that i don';t have to its just flips.

Quote from: Tepaja on Sunday,July 28, 2013, 18:53:17 Here is video from yesterday. I was practising flying inverted.. well sorta Just almost free falling upside down. I was affraid lower throttle all the way down. Because I did have some proplem while ago when lowering throttle down. I wasn´t able to spin the motors anymore.
Quote from: barneyg on Monday,July 29, 2013, 11:22:24 Do you have MOTOR_STOP defined in config.h ? and is your MINTHROTTLE set appropriately ?Personally I don';t like MultiWii';s default that the motors spin as soon as they are armed and the throttle is set to MINTHROTTLE. So I defined MOTOR_STOP ... trouble with that obviously is that the motors can completely stop if you drop the throttle too low. So what I did on my TX (9xr running er9x) was to set up a mix so that the throttle switch fixes my throttle at -100 when off but when it is on the minimum throttle was just enough to spin the props. Initially this was at about -75 which meant there was a lot of dead travel at the bottom of the throttle stick. I wasn';t content with this so I did a little digging.If you watch the TX values in MultiWii Conf and see what value the throttle is at when the motors start spinning it was at about 1100 for me ... on my TX a setting of -100 for the bottom of the throttle stick was showing as about 992 which meant there was a lot of travel before the motors kick in ... a quick search for 1100 in the MultiWii code and in MultiWii.ino I found :#define MINCHECK 1100#define MAXCHECK 1900I changed MINCHECK to be 1000 ... now when my Throttle channel is set to about -95 the motors just spin up with the throttle stick at the bottom of its travel.This way I get the best of both worlds ... on the ground I put the throttle switch in the off position ... my blades don';t spin and I can arm and disarm to my hearts content. But to fly I have to flick the throttle switch on and from that point on my motors don';t stop giving a little bit more stability in the air and I can';t accidentally disarm in mid flight :).
Quote from: Tepaja on Monday,July 29, 2013, 13:47:58 I have set MINTHROTTLE. My TX values in MultiWii Conf are for throttle 1106 when motors star spinning. Throttle stick has little dead area at bottom, maybe 15%. In Arduino Config.h page I have set MINTHROTTLE 1088. I just can´t get rid off that dead zone in throttle stick. I don´t know how I did have problems a while ago when lowering throttle in mid flight. Motors just didn´t response. Maybe it was a glitch.
Quotebtw. you wrote throttle stick and throttle switch. What do you mean by throttle switch? And sorry my bad english.
Quote from: barneyg on Monday,July 29, 2013, 16:14:40 If I understand things correctly there are two sets of values at play here ... what your FC board gets from the receiver and what it sends to the ESC :MINTHROTTLE is the minimum value the FC will send to the ESC.MINCHECK is the minimum value that the FC expects to see from the RX before it will send MINTHROTTLE to the ESC.that 15% dead zone at the bottom of the Throttle stick range is because to get the RX to send over 1100 you need to move your stick that far. You have 2 options to remove it either change the MINCHECK value in the code or change the bottom end of the range of the throttle channel in your TX. I chose the former method :)
Quote from: barneyg on Monday,July 29, 2013, 16:14:40 On the 9xr there are several 2 position switches ... one of these is marked Throttle ... I';ve used this one for my mix :)
