My Dart 250G Journey - Part 3 

Yes that is exactly right

Sorry I missed this message been crazy busy at work recently. If you fly like me then 650mah will give you 4mins give or take, I went for the 850mah and get 5mins a bit more if I fly slowly and carefully. Here are my Autolaunch settings: nav_fw_launch_thr = 1750 Allowed range: 1000 - 2000 nav_fw_launch_idle_thr = 1200 Allowed range: 1000 - 2000 nav_fw_launch_velocity = 300 Allowed range: 100 - 10000 nav_fw_launch_accel = 1863 Allowed range: 1000 - 20000 nav_fw_launch_max_angle = 180 Allowed range: 5 - 180 nav_fw_launch_detect_time = 40 Allowed range: 10 - 1000 nav_fw_launch_idle_motor_delay = 0 Allowed range: 0 - 60000 nav_fw_launch_motor_delay = 75 Allowed range: 0 - 5000 nav_fw_launch_spinup_time = 100 Allowed range: 0 - 1000 nav_fw_launch_end_time = 3000 Allowed range: 0 - 5000 nav_fw_launch_min_time = 2000 Allowed range: 0 - 60000 nav_fw_launch_timeout = 6000 Allowed range: 0 - 60000 nav_fw_launch_max_altitude = 6000 Allowed range: 0 - 60000 nav_fw_launch_climb_angle = 30 Allowed range: 5 - 45

@@bluefish3607 No worries, its the way of the world these days. Really appreciate the settings, thanks!

@@bluefish3607 would these settings work on 2s?

Hi I have moved away from analogue now and only fly DJI. But my ground station back then was an FR632 diversity receiver with a 150mm patch antenna and AXI II antenna, connected to DJI V1 goggle via a 3.5mm video jack. Prewtty simple setup tbh.

Best wishes for a great build and maiden flight.

Yeah I hope the UK Goverment let me travel, if not with LION on 2S we can meet up over the Netherlands from our own backyards :-)

@@bluefish3607 Will join you two ;-) If Marc is gonna make it from Halle i´m easy in the meeting from Oldenburg. Taking R5 ;-)

@@Slash7FPV That will be great hopefully I will be able to travel by middle of June/July

There are spies everywhere trying to get my PIFF settings :-)

I have never had a problem with GPS in terms of interference from VTX or RX fortunately, in my smaller quads everything is really packed together but it seems some people do. This problem is a known one and linked to some issue with the CADDX Tarsier camera, if I disconnect it then I have rock solid 25 plus sats and absolutely no issues whatsoever.

@@bluefish3607 Golden rule is keep receivers (Radio and GPS) together and transmitters (Vtx etc) far away from each other as possible (model size permitting).

@@OzFPVflyer Not much space on this plane and I did not want to put antenna on the wing due to uneven drag effect on such a small wing. Seems to perform pretty well with no interference issues.

@@bluefish3607 I've just built a Dart250G with Crossfire and 1200Mw AKK with a Caddx Turtle V2 and it's due to maiden any day now. I agree with you on space. There isn't any.

OzFPVflyer Good luck with maiden I hope all goes well. Its a fun little plane but doesnt like much wind.

Sorry for late reply. get launch nav_fw_launch_thr = 1750 Allowed range: 1000 - 2000 nav_fw_launch_idle_thr = 1200 Allowed range: 1000 - 2000 nav_fw_launch_velocity = 300 Allowed range: 100 - 10000 nav_fw_launch_accel = 1863 Allowed range: 1000 - 20000 nav_fw_launch_max_angle = 180 Allowed range: 5 - 180 nav_fw_launch_detect_time = 40 Allowed range: 10 - 1000 nav_fw_launch_idle_motor_delay = 0 Allowed range: 0 - 60000 nav_fw_launch_motor_delay = 75 Allowed range: 0 - 5000 nav_fw_launch_spinup_time = 100 Allowed range: 0 - 1000 nav_fw_launch_end_time = 3000 Allowed range: 0 - 5000 nav_fw_launch_min_time = 2000 Allowed range: 0 - 60000 nav_fw_launch_timeout = 6000 Allowed range: 0 - 60000 nav_fw_launch_max_altitude = 6000 Allowed range: 0 - 60000 nav_fw_launch_climb_angle = 30 Allowed range: 5 - 45

Yeah not bad for such a small light plane, rarely get totally calm days as I live by the coast.

@@bluefish3607 The wind must be very laminar.

@@jwtfpv8957 Lol I had to Google that word "Laminar" and guess I have to agree :-)

then you have to go bigger and heavier. THe more speed and wingload you have the smoother the flight in wind. Without the wind the 250G flies like on rails.

@@MarcFPV Ah ok thanks. Keep wanting to get into wings after nearly 5 years of quadcopters but keep feeling uncomfortable with how much shaking there is watching videos. So what make and model would you consider to be a good example of a smooth flyer? Do you mean something like a full sized Ritewing Drak?

@@changeagent228 get into the smaller ones first. The 250G is really good if you come from quads. If you fly at calm days it is really smooth already. You will never get a locked in feel like on quads but that's nothing to worry a out. You will get used to it. Don't get into a big or expensive one. You will regret it as it is much harder to get them fly properly without experience. Even after nearly 3 years of wings now the 250G is my favorite daily driver.

@@MarcFPV Interesting. Which 250g is your daily driver?

My Dart XL is pretty smooth and you can improve the footage further with Hero 7 or 8 or Reelsteady Go post stabilization software. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4jw3iVH7hm4.html

I have a bit of torque roll due to the 4S power and my launch throttle being set at 1800 but it corrects itself quickly as you can see. I guess it depends on your Lipo/motor combination and launch settings. I also have the launch idle speed at 1200 so the prop is spinning before I throw it. Happy to share any of my settings if you would like to see them.

@@bluefish3607 please share. Great vid

@@bluefish3607 yes please share, I have the same problem, running on 3S with 5 inch prop on emax 1404 4100kV

Well you have painted it like a tank so it may as well weigh as much. Cool looking plane looks like it should be strapped below an Apache helicopter :-)

​@@bluefish3607 Just laminated! Haha thanks!
