"Hi all, slightly off-topic but perhaps others will be interested too: Will be supported in some later version of ArduCopter V-Tail configuration, e.g. for quad? I did some searching through discussions here on DIYdrones but didn't find…"

"Hendrik Brand &Michael Utz I am having the same struggles as you described in this discussion.  Did you resolve the issue?  If so how did you resolve it? Thank you. Bret C"

"Just question to Eric: have you already flown this configuration with your ArduCopter software modifications? I'm asking because i really like this VTails and want to transform my tricopter to such Y4 quad."

"I'm not sure now, becouse i haven't started MP but i think it souldn't be RC7_MIN but something like RC7_REV."

"Thank you! I found it.    For those interested, here's the steps to reverse the yaw in Mission Planner. Located in Mission Planner: Configurator tab> Advanced Params> Adv Parameter List To change values, scroll down to RC7_MIN,…"

"I'm sorry I am very new to this controller and not familiar with it, but I do appreciate you taking the time to reply to my inquiry. I just got the APM 2.5 two days ago and I'm trying set it up for my tricopter, which was flying…"

"Of course in Mission Planner. If you have recent version of Arducopter software, you don't need to modify the code, just set it up in MP. Switch to the Configuration tab, connect your APM board and in the list of all parameters locate RC_7. By…"

"Thank you for replying. The servo is connected to channel 7 on the output side of APM 2.5 board.   To reverse RC7, do I do this in the Mission Planner? If this is the case, where do I this in Mission Planner?    "

"If you have tricopter configuration and yaw servo is connected to chanel 7, just reverse RC7 ."

"How do you reverse the yaw on the APM 2.5 using the mission planner?"

"Guys, after reading through all this discussion it is still not clear to me if it affects PPM too. Since I had some strange freezes with my FrSky RX i'm asking this question (searching of any possible failure reasons). For instance last time I…"

"aaah, thanks ;o) soo many items in this menu (new for me)... "

"As for Mission Planners - Flight Planner, does anybody here know where went Save and Load WPs (to and from text file)?"

"OK, thanks for explanation. Both cases seems to be reaction to tilting but counteracts (rudder movement). Or second case depends moreover on lateral acceleration? "

"Hallo, can somebody clarify to me what movement orientation is intended for rudder control surface? For instance when APM is in stabilize mode and the plane is leveled then I move the plane in roll axis -> left wing down, right up. What direction…"

"Just use these settings. Put them into your APM_Config.h: # define GPS_PROTOCOL GPS_PROTOCOL_MTK16// # define TELEMETRY_UART2         DISABLED # define CONFIG_RELAY            DISABLED # define CAMERA                 DISABLED # define…"
