Thank you for the response.
As for the Failsafe options, I would like CH-5 to operate the release and then have the plane RTL. It would seem that I can only enable or disable the throttle channel for Failsafe, which I don't want to do.…"

Objective: Build experience with Balloon launched ArduPlane for future high altitude flights. The purpose of the flights is for amateur photography and…"
Prahas David Nafissian replied to Andrew Tridgell's discussion ArduPlane 2.68 released"Hi Graham,
Is there any way to turn off the failsafe entirely? Your suggestions are super for regular flight, but in my app (dropping an RC from a weather balloon) there will be no radio signal. But I still want it to continue in Auto…"
Prahas David Nafissian replied to Andrew Tridgell's discussion ArduPlane 2.68 released"Hi Guys,
In this version as in previous, Condition_Change_Alt not working. I make param 1 15 cm/sec,
and param 2 an altitude (say 600 ft) which is supposed to be the end condition. I write the WPs.
When I read the WPs back, it keeps the…"
ModeratorGraham Dyer replied to Prahas David Nafissian's discussion Do_Set_Parameter
"In the new firmware due for release shortly, currently in ArduPlane you have to put the DO_SET command between 2 waypoints, the second waypoint is just a dummy and won't be flown to but for some reason it needs to be there otherwise the DO_SET…"
ModeratorGraham Dyer replied to Prahas David Nafissian's discussion Do and condition commands / First point always does one loiter turn
"Currently (until the new version comes out) you have to put the DO-JUMP command between 2 waypoints, the second waypoint is just a dummy and won't be flown to but for some reason it needs to be there otherwise the DO_JUMP won't be executed."
Prahas David Nafissian replied to Peter Cathcart's discussion Can't seem to allow "Swooping" or steep descents"
Set Alt_Ctrl_Alg to 1, and Lim_Pitch_Min to -55. The first tells Ardu to
make hitting altitude the first flight priority."
Prahas David Nafissian replied to Mike's discussion Hard vs. soft waypoint altitudes?"In the advanced parameter list, change Alt_Ctrl_Alg to 1. This tells Ardu to make reaching altitude
the top priority. (Don't forget to write the new param list).
Also, make Lim_Pitch_Max = 90. This will allow a steep…"

First commands for balloon RC glider mission, and condition command help
Hi,So happy to find you folks! I've been working on thisproject for 6 months, after a successful "regular" balloon launch.Any comments much appreciated...My half-ideas are as follows:In the parameter file, set "Throt_Max" to 0. The RC hasto glide home due to power constraints, until it is visibleto the pilot, who will then switch it to manual and land it.I don't know how the condition commands work yet, butI think there is one related to altitude.I think you always need a waypoint command to…See More

Take off in manual -- get it level. Then switch to stabilize, and see how it works.

flight planner, take off in…"

I'll google the Niro RQ-11. Good to know you are thinking delta wing...I'm leaning that way too.
