MiniTalon: from Maidencrash to epic FPV Adventure

Here in this video you'll see my experience over the last 2 weeks:
from maidencrash, luckily I announced it that way before launch so nobody was surprised, to successfull FPV mission!
I got this kit for around 50$ (banggood) LAST YEAR after the flights with my XUAV One  (the one with the folding prop AROUND it's tail-rod). The One was just not a good flyer, gears around this pusher are weak...
Then I read only good things about this easy, proper flying Mini Talon. It's a shame that I didnt build this earlier! Had to put aside my quads a little for this :)

►Main features:
- BIG SPACE for things like Autopilot and FPV equipment
- good speedrange (~35 to 140kph)
- easy build (really easy)
- long flighttimes (you can use 5.000 to 10.000mah 4cells) I get really safe 25mins or 20km travel with around 3.000mah used

►►►Important tips (also seen in video):
- CG is 55mm from leading edge of wing (not 76mm like manual says!)
- throw it horizontally not at an up-angle, give it a nice toss, dont use full throttle (torque left!), check this video guide to see how it's launched
- secure the main battery (it WILL affect your CG if it can "roam around" in your fuselage :)
- create some motor air vents in the back - my motor got really hot (ok it's summer here)

FOXEER Legend 3:  TVOUT warning
ATTENTION: DO NOT ONLY POWER IT FROM EXTERNAL SOURCE - with small variations in current the cam will reboot, a fat screen will ask for movie recovery - TVOUT is blocked!
With it's battery in I had 4 long flights now without issue - cam is always charged. Maybe I will move on to dedicated FPV cam...

Foxeer Legend3 TVOUT and Latency compared to Runcam2 and 3

You wanted to know how the legend 3 looks if used as FPV cam (tv out). I installed it on my new FPV plane (MiniTalon) but before this I tested the latency against Runcam2 and 3.
While the latency of the Legend3 isnt legendary, the imagequality IS! The stabilizer didnt work great for me - better leave it turned off if you use the liveout.
DONT use the cam WITHOUT battery (if you power it from your plane). While this will save some weight, it can lead to disaster!

Jump into the area of interest for you with these jumpmarks (clickable on youtube!):
===========
00:16 Legend3 Latency PAL
01:19 L3 in NTSC faster!
02:12 L3 stabilization - more lag?
03:10 L3 with 4k mode
04:33 L3 Liveout quality

06:02 Runcam2 Lantecy
06:47 Runcam3 Latency
07:18 Legend3 - final thoughts
08:29 IMPORTANT - USE the BATTERY even with external power!
09:24 RECOVER MOVIE?

10:58 L3 Stabilization ON 1080p50
11:15 L3 Stabilization OFF 2.5k50
11:32 L3 Stabilization OFF 2.5k50 VEGAS software stabilization on

Runcam Eagle 2: great picture, latency lower! thoughts, testflights, DVR footage



I took a closer look at the claimed better latency here. Check my new method - I like how it visualizes the time-delay...
The cam is really good. Image is one of the best currently available, only the missing OSD Volt option is a small downside.
At the end you'll find a comparison with different cams - check my VIDEO INDEX:
===========
02:12 latency Eagle2
04:14 Eagle1 compared (how much fast is Eagle2?)
07:34 Swift Mini Latency
09:05 SUMMIT (about Eagle2)
09:46 Runcam Split Latency, Split thoughts
11:53 Eagle 2 Downsides no OSD
12:33 Eagle 2 positive: very nice imagequality!
12:49 more FLIGHT FOOTAGE
14:25 even MORE FOOTAGE ( MINI Swift, HS1177, EAGLE1 and 2, Foxeer MONSTER V2
16:22 Runcam SPLIT DVR Footage (some of you asked!)
