- This is the maiden of the ZOHD Dart 250g I bought here bit.ly/39kPmNB with a FULL RUN DOWN on my current setup as I'm using a 2S li-on pack for it with iNav, hence the flight times are CRAZY long! FULL setup details below, Press SHOW MORE to see them. Matt

I went for the FPV kit, however now having owned this one and the Drift, definitely go for the PNP kit. The motor, ESC and servos are "good".
UDPATE:
This configuration has got me over 40Km in total distance flown!

Update: With this setup I have flown the the Dart 250g for 42Km total distance in one flight. Expect a couple of follow up videos with the Dart 250g as I've flown it every day its not been raining since it first flew! Any questions or comments welcomed below, Matt
I see that you like this one better than the zohd fart from previous videos 🤣
Very cool. Been itching to build a powered wing, seems like a decent compact option. Thanks for the vid!
My fpv Drift is on its way.
O yes.
Thanks for the info matt.
you are the only one that was I was able to easily find who is using the li-on. I searched for dart lion and found you. I am new so I am doing research and I believe i need lion for the long flight fpv aspect of things.
I was having so much trouble trying to get my Dart to Launch now I find two different videos where the launch angle is set one is 25 yours the other one is 30 mine was set at 18 I'm going to try to adjust this setting and I hope to God I can get in the air finally I'll keep you posted you make awesome videos very good you're basically the Joshua Bardwell of fixed wings
Nice review matt i learned something today keep it up
Hey Justin, happy days. Matt
What a great model. Another win for zohd
Morning Adrian, yes, this one has had some knock on effects. You'll find out about them hopefully soon :) Matt
Got one getting delivered today. Will be nice having a backup plane for when my ar wing gets ripped to pieces
I found that gluing the vertical stabilizers to the wing over the full length prevents the bottom part to break off one sad day. Love this wing. It's not so fast but super agile and stable. I've got an air unit in it. Are you going to share how you laminate and add that silver?
Hi, great build, planning to do very close build! Lots of info! How do you laminate? Some link to foil and tools? Thanks!
Hey Matt what sort of flight time vs the drift would you expect thanks
Thank you. Would someone have suggestions please? I’ve noticed a split occurring on the flap (the thin line) where It meets the main wing. How would I go about repair/ strengthen it?
Nice video and informative 👍
By the way, I just received my Dart250g and maiden lady Sunday,flew it with 3S 1000mah lipo, in manual mode, without the Kopilot.
What I found to that, it is very sensitive, and influence by some level of winds condition; competitively it much difficult to handle than my old Z84 with similar setup; may I have your comment?
Question about Dart250g would like to seek for your professional opinion:
1) The CG spot is it in front of the CG point, behind the CG point, or on-top of the CG point?
2) If the CG is right, does it need come level of reflection? Like about 2-3mm?
Why I am asking these, is because during the maiden, I need holding the the elevator up about 10-15% on the Tx stick, whenever I speed up, else it will immediately nose down and hit to the ground quickly.
Very much appreciate your kind advice.
Thank you.
Hi: when we talk about long range fvp, there is actually two things that have to be long range, right? ie the vtx has to be long range, and then the control inputs transmission and receiving has to be long range as well, right [ie crossfire/TBS/ELRS]?
Hi, how did u solve vtx power requirements of F411 running on 2S LiIon? F411 needs min 6V to run and my RUSH Vtx needs 7V-36V. Many thanks!
Can anyone tell me what is that interference at 15:25 where the screen flickers to black instead of going to static. I had a similar issue in my goggles a few weeks ago and couldn't find the source.
Nice job you've done with this one! Hope it's not too heavy!
Howdy fella, oh it flies brilliantly. Honestly amazed how well it flies on 2S for the speed it does too. Matt
@@RagTheNutsOff no no no sir. This thing comes alive only on 3s. Night and day, truly.
Hi: I am learning fpv. I was an RC flyer 20 years ago. So, back then, we used PMW or PWM receivers from airtronics or specktrum. Is that the reason that you use tbs or crossfire or ELRS instead? Ie: pwm only gets like 1 or 2 km max. So, if I buy a Zorro from Radiomaster, I should not try to get a pmw receiver, right? I should go for something like a module of some sort, right?
do you think this can handle a 4000mah li ion?
Pretty excited to see this. Mine is being delivered today. Gonna set it next to my dart xl when it is done then wait for a nice say to maiden them both lol. I had alot of trouble getting the smart audio to work with my akk and inav so I switched it to a tbs unify pro on the xl. Not sure what I'll use on the 250
Lol u switched to tbs unify just because of smart audio?... U will be disappointed when not going for akk vtx.
FpvBerget it was an easy swap. If I decide I need more range I'll throw the akk back in. But for early setup and troubleshooting I wanted the option to turn down the power. Considering switching to 2.4 but in reality there aren't alot of places that are good for long range around me so I end up not really pushing the limits of my vtx anyway
Morning lads, I'll let you into a secret, I've never used smart audio! Matt
RagTheNutsOff this will be the first time I've used it. It's not a deal breaker if I can't but I already had the vtx laying around so I figured I would give it a go.
cant wait for the premier , one question: where can i buy that vtx and antenna? please
Hey Jack, that's definitely not the Matek 1.3 vTx and the antenna, I got that with some tx's from surveillezone. I have heard it called a VRX antenna, that's all I know. Matt
Nit: it's INAV not iNav
I like iNav. Why is it INav?
I thought it was 👀Nav. 😉
@@DeeJayEll I thought it was Apple.
Well. I suppose Pawel can call it wat ever he wants. 🤷🏼♂️ Just as you can call your baby almost wat ever you want. 😁
@@zatbr1 My Dart is an iCatcher, not an ICatcher or ICATCHER and definitely not an apple or baby!
Thanks Matt. Got one on your link.. buying 18650's.. should i go for the 3000mahs with 10A discharge or the 3500's with the 5A discharge? Thanks in advance for your expertise, and help.. Without you, Lee, and Andrew, I would probably still be grounded.. So good to fly! Thanks!
Howdy Clay, it depends on your needs. If in doubt, go for the 10A ones. More head room for larger models. For me the Darty250g and Drift only pull 3A on a good day, so a 5A max is fine as it will have a burst of around 6A on launch and thats it. However in a mini talon, yea 10A might not be enough and you would probably double up anyway to make a 2P pack anyway. Matt
Hi Matt, you mentioned your video tx is 1.2ghz but you have listed 5.8ghz gear in your description. Could you tell us what your1.2ghz gear is inc what antenna you use on your goggles etc.. Thanks.
Howdy, see the description it is in there. As for antenna, just dipoles. Matt
Have you tried spinning the rudders to opposite sides? Saw a couple folks do it with results that varied..
Howdy, I've not. It flies fine as is so I'm loathed to tweak it. Matt
;-}> auto launch is what I'm hoping will help me learn to fly. I get the SIM but I never get passed takeoff usually
Between this and the nano-drak, can you get the same efficiency and flight times?
Morning, I have a nano drak prototype, no idea on its efficiency though. The Dart 250g is 70mah/km or less (recently just 30, but that was with a massive tail wind). Matt
So Matt, the Drift or the Dart?
I cant have both unfortunately , flown mostly gliders and the odd wing up untill now, not super experienced but not a total novice either, which would you recommend? 🙂👍
Howdy Fraggs, oh the Drift. The dart is great fun, but it can be twitchy without a flight controller, the Drift, much more laid back. Does that make sense? Matt
@@RagTheNutsOff Yeah makes perfect sense , I will definitely be fitting a flight controller (its worth it just for rth )
Just need to find a decent priced Drift in stock now 👍
Thanks for the advice
What is allowing your FPV view to appear like a true flight screen?
iNav OSD "on screen display".
Quick question. Running a 2s 18650. The VTX needs a minimum of 7v. Is there a risk running 2s and dropping below the recommended voltage?
Easy, test it. Mine works down to 5.0V and at that voltage I have other issues ;)
@@RagTheNutsOff Thank you so much for the reply. Will do.
So the next question that arrises is “Dart250 or Nano Goblin ? “ opinions please lads ...
That's easy. One is crazy expenses and one is not! Matt
Planning to weld a Li-ion pack for my G2 Ranger, have you done this before. And do I need 3s 1p or 3s 2p? Just wondering. Suffolk is bit windy @ the mo. So it's fixing/building weather. 👍🏻
zatbr1 from what I understand it really depends on how many amps you pull on cruise and takeoff
@@chriswayman7240 I was more concerned with weight and CG. The cells I have are 20A so even a 3s 1P will be enough. I guess I will just make it and see🤷🏼♂️
Yes, I have other videos on making li-on packs. Its dead easy. As for 1P or 2P, 2P is twice the capcity, IF the model can take it. If it can take more, consider 3P! Also it may be easier to go to 4S 2P for more power over 3S setup. Matt
And max amps is a consideration, I'd not worry about it if it's just for 20 seconds at launch, normal cruise throttle to 75% is the area to be concerned about for current draw
@@RagTheNutsOff thanx Mat. I repack power tool batteries so building the pack is easy. I did not consider the 4s yet. It all sounds good and I shall give it a go as soon as I can confirm that my esc and motor can handle it. Thus is going to be a interesting experiment. ( 3s 1p then 3s 2p then 4s 1p and depending on CG 4s 2p) thanx for the input. I shall get building and looks like summer is here for 3 days this week perhaps even make a comparison video on my Ranger G2 👍🏻
💪💪👊👊
Howdy Matt, great channel. Will this build hit under 250g? Cheers fella..
@MAD GRUMPYMAN equipment dependant. But thx anway..
@MAD GRUMPYMAN no worries fella, I have one myself. Looking forward to watching Matt's vid. I was having issues with power on small triblade prop on 3s, swapped to bigger included prop, better! Would like to try 2s li on and stay under 250. 👍
@MAD GRUMPYMAN I agree, especially on the jump up to 25kg. We have something similar, I'm still unclear. UK btw
My first flight ended even worse. My vtx died a minute after launch!
oh balls Dylan, sorry to hear that!
@@RagTheNutsOff I'm not exactly the most talented LOS pilot so it was a nervous 30 seconds trying to bring it in to land!
Ive been watching this video for a while. Is he asking honest questions or nit picking? (guy with the man bun)
6 more days
Take the lead out and put on a 2205
Hahaha yea that would be nuts!
Long haired dude sounds tired.
We all were, me & Andy were up since 02:30! Matt
