  • Keep in mind that the big Talon and Mini Talon are two different animals. You'll need Parameters for the bigger Talon. 

  • Ok folks, I've read through all the comments etc and after having just purchased the Talon (1720mm wing) and currently getting it setup for its first flight I am looking for anyone to share (gracefully) their param setup. I see A post a few down tha Scott has param for a mini Talon, is this a similar setup that would suit the big Talon? I have Pixhawk, airpseed sensor, 3DR radio fitted. Much obliged for any assistance. I will be using mainly for auto flight missions.

  • @ Antonie, Haven't really tested for stall speed as such, but here at the coast it seems to be in the 20 - 30 Km/h range. If you are straight and level, stall is a non event anyway.

    I haven't tried stalling it in a bank, yet !!!

    And I've moved the CG back 1 CM.

    I'll do a full kit weight tomorrow, and let you know what my Talon weighs in at.

  • Hi Gustav, I'm unpacking my Talon as I'm writing this.:)) I do not need looonnggg flight times...sun tan on the ceiling of your mouth:/, sorry - the point being that she will run on a 5Ah battery = light setup with no FPV gear, just down facing Canon and APM2.5. Have you tested for stall speed on your bird?

    Thanks, Antonie

  • Has anyone else had problems with their talon massively losing altitude in sharp auto turns?

    I already had a well-tuned Skyhunter (similar size, weight and speed) when I set up the talon, so I started with the config file for from the Skyhunter.  My Talon is set up to use v-tail mixing and that's working well.  I also set the rudder coordination gain to zero.  I have noticed that just using the v-tail rudder mix while in level flight causes the nose to drop significantly. I've tried moving the CG around (significantly) and it didn't help, but of course had other effects.

    Changing PTCH2SRV_RLL does help, but I'm currently up to 1.8 and need even more.

    At least now it's not doing a power-dive towards the ground when I try to loiter with some wind.

    I have a calibrated and working airspeed sensor.  Everything else works fine, including full auto missions, I just have to keep at least 50 feet of altitude margin because it will lose that much in a tight turn.

    Given the way TECs works, as it starts to lose altitude, it applies more power.  I have the normal cruise speed set at 40 MPH, and with the default 1.0 value in PTCH2SRV_RLL it would get up to like 65 MPH at the low point, then once headed back into the wind, it would balloon way up and slow way down to get back on track.

    Should I just keep cranking PTCH2SRV_RLL higher?

  • Esteban,

    This is what Scott uses, looks very good...


    And this is his blog http://diydrones.com/profiles/blogs/mini-talon

  • can anyone post a.param for the talon mini plz?

  • Hi Dave,

    I've been flying RC since '80, so not too many surprises for me.

    Computers, well now, entirely new subject......

    Talon should be running at about 14 - 16 m/s, from flights up to now.

  • Thanks Dave,

    I'm a bit stupid regarding tuning :-(

    I think Bixler/SkyWalker flies somewhat slower than Talon.

    My Talon is already going to about 45 degrees when it reaches a waypoint.

    I'm using Juan's params, slightly modified.

    My Talon is running too fast for optimal efficiency, I think.

    Getting one flight a week isn't helping much, for tuning :-(

    The Vtail is something new to me.....

Pixhawk Mini and Spektrum Controller

Hi friends,I'm currently trying to integrate a pixhawk into my XUAV talon that I have built for aerial photography. This is going to be my first time using a pixhawk on a plan rather than a copter drone so I'm a bit lost. First, I noticed that in qgroundcontrol when setting up my pixhawk, there is no profile for the talon's v-tail design, is there a guide on here or someone who would be able to help me download or setup a profile in qgroundcontrol that would be appropriate for the talon?Second,…

X-UAV Build

Hi all,I'm looking for an airframe that will ultimately be aimed at mapping/orthomosaic type projects and the Talon is one we are certainly interested in.I know this has probably been asked 100 times, but does anyone have any information or could point me to links of existing threads that outline a good build and components that work well with the talon.I'm in Australia so pretty sure there won't be much available here in country so will be looking abroad to build the kit.Are the wing…
