The tiny pan servo is amazing, must try that now....😀😀🇬🇧
Awesome flying and review, dude! Really nice! 😃
It seems like a fantastic option indeed!
Stay safe there with your family! 🖖😊
Thanks! I enjoyed building this one, one of the smallest I've done yet... lol
Love servo mod. nice one.
Nice build Keith. That pan is awesome!
Nice to have my thoughts confirmed on the ruddervators too. I couldn’t get anywhere near the manual recommended 10mm of throw. Think I’ll be going for that second hole too, and boosting the servo outputs to 120%. Maybe even adjust the mixer to give more yaw authority.
Thanks! Yeah when I first flew it, the pitch control was very weak, it took full stick to get any real response from it... lol It feels a lot better now. I found the roll was way too touchy even with the linkages moved for minumum throw. Setting the manual rates for 85% tamed that right down though. It's a nice flying little plane once it's all set up how I like it.

Brilliant video! I now own a Zohd drift and really love it, but I am looking for a similar plane with more space in the fuselage and that also runs on a 2s lionpack. I think this may be the plane I am looking for. Thanks for this amazing video!
Great video! One quick note: With CRSF and Inav 3.0 - 2.6, the regular RSSI is the same as crsf LQ. Both show LQ. Starting from 3.1, the regular RSSI will be based on signal strength instead of the "old" LQ fix.
So you're saying the default "normal" RSSI reading is just showing the same thing as the LQ item on OSD? I wasn't sure what the normal RSSI item was showing with Crossfire. I've seen them reading slightly different numbers, but they generally do stay pretty close to the same thing. (This is 3.0.1) If they are the same I'll just remove one and get rid of the redundancy... lol
OK, just went and learned more about the auto RSSI stuff... lol Yay Darren for explaining things! ;) czcams.com/video/s0UG0LxWI44/video.html So it seems I am just showing the same LQ twice the way I have it set up. Once in the auto RSSI source, and again in the specific OSD item for CRSF LQ. I'll sort that out then!
@@bonafidepirate yup. That rssi solution was to show LQ in the OSD. From 2.6 and up rssi, LQ and SNR come straight from Crsf. I use dBm rssi, LQ and SNR alarm set at 4. For 3.1 I added normal rssi to be from signal strength in percentage.
@@Onefgear Good to know! Thanks for cluing me in... lol I've already corrected it on the OSD.
On my zohd drift build I did install a 12v 20mm fan on the vtx, because it gets v hot and shuts off, just couldn’t get good air flow to it. With the fan mod I’ve never had a shut down.
I've flown this one, and the Dart 250 a couple times over the past couple of days trying out the heat sinks, they work well! The vTX comes down cool every time despite the actual temps outside in the upper 90s. The Dart's vTX doesn't have smart audio set up, so it runs at full power all the time. It gets hot before taking off but cools back down in flight. I need to set up soft serial to use smart audio on that one so it can run low power until I arm... lol UARTs are limited on the F411-WSE in there.
This may need the WalkSnail treatment soon. Great video. This looks like a really good flyer.
do you have a step by step guide on buying equipment, building and set up? :)
Could you share your PIDs of the plane because I am unable to fly correctly in stabilized modes and I do the autotune correctly. My plane in acro mode flies correctly
@bonafidepirate Thanks for the honest review. What would you recommend for a flying wing for novices?
nice setup! could you upload the pan servo mount stl?
Another great vid! I don’t think you mentioned the final flying weight with this setup anywhere in the video. What is it?
Thanks, I did forget to mention that... lol 306g as shown here.
WOW I love your setup. I thing I might steal some of your ideas. Especially the VTX and antenna position and the Pan servo..... OK basically I might steal everything xD
Steal away! lol That's what it's here for. ;)
A bit late to the party but i really like the way you have the vtx in the side of the fuselage. Did you notice any improvement in video range this way?
I just found this video. I'm impressed on how stable it flies compared to my original Nano Talon. Could you please share your v tail mix settings? On mine I use 100% stabilized pitch and 50% stabilized yaw but l'm considering using RC yaw instead because I suspect that it may be the FC controlling the yaw that's causing the Dutch roll wobbles.
Mine set up with 50% pitch and 50% yaw, both stabilized. Here's a complete dump from 3.0.1 that's currently installed in it, if you want to look through it. Note that in the video, it was a calm day with smooth air, and the little plane will still get bumped around a bit on rougher days. pastebin.com/c7yzLJTk
do you think that this little plane will fly well with 2s 21700?
Niceeeeeeeee! You sound really stuffed up. You okay?? Brilliant on the pan servo!
I like that little servo too! Small, light, smooth, immune to 900mHz, and 180º without opening it up. It's a keeper for the small ones! I'm good, just the usual sinus stuff I get around this time each year. lol
hallo my friend, how did you glue the tail fins?
I'm a little hesitant to use the Racerstar F405 I bought months ago, after watching em burn up on 1st power up & other issues, etc. Looks like you got it working pretty good.. Hows the T-250G with light to medium wind??
Light wind seems fine, I flew it in about 10mph wind a few days ago and it got thrown around pretty good. It does good for what it is, but it's always going to be a small/light plane... lol I saw some reports of this FC going up in smoke too, at least two of them came back later and said they'd messed up when soldering leads on and the solder contacted the board above. It is rather tight in there and probably an easy mistake to make. So far I haven't had any problems with this one, other than the bluetooth adapter not working reliably in Windows. It does seem fine with Android and the Speedy Bee app though, so I guess that's good... lol
What is the weight as you currently have it set up?
Amazing! Is it possible to get the STLs for this tiny camera pan mount???😬🙈😎
Sure! I just uploaded it here: www.thingiverse.com/thing:5410861
Tried iNAV 3.00 couple weeks back. The constant flight trim worked out the box for me on my little Ranger G2...You need 1.3g video on the little guy to exploit it's theoretical range IMO...😀😀👍🇬🇧🇬🇧
I'd love to get a small 1.3GHz vtx on there... lol I don't know how well it would work though with everything so close together.
@@bonafidepirate I have a number of 5 inch quads on 1.2g, now using Crossfire RX's...You just need a 200mw vtx...😳👍😀🇬🇧
@@EnglishTurbines more power makes the problem?
@@blackterminal Yes, on 1.2g video, 200mw of RF power will give you at least 8kms of range using a decent VRX setup....More than enough for a small quad or plane...😏😏😀🇬🇧 More RF power WILL cause GPS problems for instance as separation of GPS and VTX is more difficult on a tiny plane...🤔
Cool, planning to buy this or dart 250 after seeing your videos. How did you set pwm pulse for servo from 500 - 2500?
On the outputs tab in iNav configurator, you'll notice the MIN and MAX for all servos default to 1000 and 2000. These are pretty much the same thing as setting endpoints in your radio if you were driving the servo directly off a receiver. The lowest MIN value allowed in iNav is 500, and highest MAX is 2500. I just changed the one for my pan servo which is plugged into the S6 output on my FC. All the others are control surfaces and set up normally. I'm not sure if all servos will accept that wide of a range, if not you may need to play with the values to see what it will work with.
@@bonafidepirate thank you so much.. I'm gonna try it with cheap servo first.. 😁
You have a link to buy the servo you use for the camera, thanks a lot.
It's a Turnigy TGY-1440a hobbyking.com/en_us/turnigytm-tgy-1440a-analog-servo-v2-0-8kg-0-10sec-4-4g.html I like that it isn't affected by 900MHz too. I went through my parts bin and most of my spares this small were jittery near the Crossfire receiver. This one is immune!
how do you connect that race star f405 mini via bluetooth? How long is the timeflight on this thing?
When powered up, it shows up as two bluetooth devices. One called "inav" with no pin, another called "ardupilot" with a pin "1234". I can see those, most of the time, and something they'll pair and connect. When they do you'll get a serial port showing on the PC. (two actually) Connect to that like normal, with a baud rate of 57600 and it should work. In iNav, you'll see UART1 has MSP turned on, that's hard wired to the bluetooth adapter. That's how it's all supposed to work at least... lol
Using Windows 10 remove the incoming Bluetooth serial port, keep the outgoing one, usually helps with stability.
Thanks I'll give it a shot! It took forever just to get it to pair though, so I don't know if it will help.
FYI, I just tried using the Speedy Bee app on Android and it works fine, connects and loads fast. That rules out a problem with the module on the FC, seems to be a Windows problem I guess.
@@bonafidepirate can either the issue mentioned above (had this problem with ultimatelrs/openlrs) or maybe even the bluetooth module itself (have a toshiba laptop which the bluetooth module never works properly vs a thinkpad that works great every time)
Nice! Trying to decide if to get this or the regular size talon. 🤔
The GT Rebel flies great but is not as durable as I'd like. Because of the big square front, if you nose in at all it catches and breaks the nose pretty easily. Or if the ground is soft or muddy it's just like a big shovel. On the other hand if you do the opposite and the tail drags at all it'll break the little foam fins on the back. They send the extra for a reason!
This small one is pretty neat, just for the novelty factor of having such a small full featured and fully capable FPV plane... lol With the larger ones you'll have a lot more options for what gear you want to build it up with, and gear placement too. If you want the small one, or need to keep it this small for some reason, it will get it done. Otherwise I'd probably go for a bigger one. Even the Nano Talon will be a bit easier to fit with a wider variety of FPV gear. The OG Mini Talon has a long proven record of being a capable plane that works. I haven't tried the V2 of that yet. The Talon Rebel GT is nice in the air, but I don't like the nose on it, and I found it somewhat difficult to launch and get it flying unless I kept it light with a smaller battery. I've also never flown the full size 1718mm Talon. One thing is for sure though, there's a Talon for just about everyone! lol
@@bonafidepirate yeah I agree about the nose. It's practical for camera and batter placement and getting ya hands in there, but not great for anything else smh
I ended up getting the nano talon evo 🙌
@@bonafidepirate I had a full size Talon. Found it very hard to fly and it crashed and tore itself apart.
What’s your most efficient plane in your opinion?
Hard to say as I haven't really pushed for efficiency, usually once I get to the point I can fly for an hour or more I don't pay attention anymore, it's rare I need or want to fly longer than that... lol
Wish you had kept the auto tune we my dart has serious issues after auto tune.
May I contact you to test my Amazing Amazon Products
I think zohd planes are over priced It seems greed tied to thinking their brand name is worth $$$ I don't agree.
