Mr Nick I still can’t get over your flying. Makes it perfect for reviews. You are shredding fast, doing awesome tricks and I love the punchouts. Absolutely love the videos and love the micro quads.

[@NickBurnsFPV]

Thank you so much.

[@fpvspin1605]

Hi Nick, I been out of FPV for nearly 2 years for various reasons but I always used to watch your channel, just wanted to say you were always a fast flyer to me but after not watching for so long... wow really fast and so enjoyable to watch with so many more tricks in your flights. In short I love it, really looking forward to getting back into the hobby. So glad I kept all of my gear.

[@NickBurnsFPV]

Oh thank you. And thank you for letting me know. Hopefully your able to find time to enjoy fpv again.

[@briansowder10]

I'm still a speedybee battery strap promoter. Very good little straps for our 1s and even 3s micro applications

[@MCsCreations]

Interesting. I'm going to search for it, thanks! 😊

[@NickBurnsFPV]

I have a few of them as well. In this case I think they might be a touch thick to thread through without disassembly. Thats where the cheapo depo comes in handy.

[@ChrisHarmon1]

Just looked at these and 1.7 grams(before possibly being cut to length) isn't terrible for the convenience! I have run into issues with the strap or it's hairs interfering with the flight controller. Normally this would just mean 4 spacers but with today's HD VTXs the stacks are getting a bit tall for my taste, though Fractal has found a way to keep his low with no props ❤

[@IanMacKenzie_IIsWe]

iFlight also does a nice small 10 x 100 strap, works great for 660mah on Mobula 8.

[@johncarold]

Hi Nick, Great video and review of the Sub250 Nanofly20. Yes I want one. I just love 2s 2in quads. And I can't wait to fly one. Thanks again for the video and information about this quad.

[@lightbulbjim]

Yes! More 2" 2s! I wish they used four screws on the motors though - I find those tiny screws on the three screw motors are easily damaged or lost. I must confess though, I picked up a Nexa 2.5 based on your review and, after some adjustment to get used to the 3s POWER in my small yard, my 2" 2s quads are now having some rest time in a drawer.

[@NickBurnsFPV]

avantquads makes some good ones for sure. good to see them back under the new avionrc name.

[@MCsCreations]

Fantastic flying and review, Nick! 😃 It looks like a great little quad! Anyway, stay safe there with your family! 🖖😊

[@lemonsquareFPV]

Only reason they used the HQ51mms is that they got them for 0.02 per prop. Gemfan 2015 or even the 2008 would work significantly better in this build. The frame to me is a RacerX and it always will be, but I’m not super long into FPV. I use washers for the M1.4 screws for the camera and motors and they don’t come out or move. 100% recommend doing this.

[@chrisbee5481]

GF 2015 props are best for these 1002 or 1102 motors. The new GF 2008 are basically very similar to the HQ 51mmx3. Hold them side by side and blade pitch Looks the same. The gemfan 2008 are thinner and more fragile than the HQ. Both bend and break. The 2015 is the only good prop. Talking props, the gemfan 3630 are awesome 👌 Not really for sub250 builds, but fast and durable on 2005 motors. 180kph no problem

[@lemonsquareFPV]

@@chrisbee5481 I agree with everything you said… Except, even though they look similar the 2008s and 51mm feel very different in the air. 2015 is one of my all time favourite props as is the 3.6 you mentioned and the 4.6 I’m currently working on. Props make such a huge difference! I’m so glad we have good ones!

[@chrisbee5481]

@@lemonsquareFPV do you know if there are any new 4" props coming out? Iflight has the new F4X with new HQ 4x3x3 props. I'm not sure if they are basically the same as the old hq 4x3x3 , but with the new grey PC plastic. The only good 5mm mount 4" props are the emax 4024. We need a 4" prop similar to the 3630 scaled up.

[@NickBurnsFPV]

yea, Racer X will always have a fond place in my heart with Bryon.

[@lemonsquareFPV]

@@chrisbee5481 there is yes. Most development is in the sub 5” sizes between 4.5 and the 4.8 + 4.9 that were released not too long ago. 5” is too big of a prop for proper freestyle on a lighter no GoPro build 4.6 is my favourite BY FAR! 4.7 from last year was good but dropping to 4.6 just made a literally perfect flying freestyle quad. 4” wise I already love and daily the GF4023 and HQ4x2.5 + bi-blade version, and see no reason for anything new… looks like you want a more durable prop… use the older 4” props the HQ DP and Gemfan WindDancer. But honestly just run properly engineered modern props and change them 😜 I AM open to suggestion though, how would you change the props? I dislike the way all Emax props feel in the air 😜 but they ARE great for beginners… heavy and linear. Spool is WAY too slow on heavy props and I just can’t for my style of flight. They are good for heavy or cruising, but I am the opposite of those things 😜

[@OVERKILLFPV]

I bought the Nanofly20 1s version. And the motor wires are aweful. Plus a couple of faulty boards as well. Nice frame and canopy different components. And you can definitely get a good ripper.

[@bentravis99]

Love the videos Nick, thank you!

[@helixinwonderland8938]

Nice Nick! I've buit my 2s 2inch with the MIniTwiglet frame that is pretty similar to this one.

[@NickBurnsFPV]

That is a similar design. changes are pretty slight from my memory.

[@ChrisHarmon1]

I made a 2s mount STL for the original that may fit. Previous reply was deleted by YT I think, so anyone looking can find it under Nanofly20 on printables.

[@NickBurnsFPV]

Yes, I saw your comment in the email, but when I went to look for it...poof gone...not in the spam filter on the youtube studio either. I wish there was better controls for this stuff. Had a video taken down recently for violating youtube content/linking policy. It was a link to a betaflight dump. Had to appeal that and got it reversed. So weird, I probably have 50 videos with a link to a betaflight dump file.

[@ChrisHarmon1]

​@@NickBurnsFPVI have had it happen before with links but never the mere mention of a site without the dot extension. Can't imagine the content lost over the years by those filters.

[@MysteryD]

The way to fix that little blip you call prop wash, is to turn down throttle boost, to 1 or even zero. Also would help to lower the TPA breakpoint a tad, depending on what the D term values are.

[@aaronvandegrift6478]

I need to learn how to tune…

[@KOrnhOliO1]

Did you try it ultralight with your favorite Nano-tech 300mah lipos? I'd never use those 500+ mah lipos. Don't own any, and I'll never buy any. It's all about weight... They do anything to make 14K motors all of a sudden be OK on 2S? Thanks Nick, nice review, like always! 😎🤘

[@MrCrowleyandhisdrone]

Great review, thanks Still a rippin madman, peace🙂

[@ivanluhi]

Nice review, as all of them! If you had to pick one frame to build a 2S 2" from those you liked so much (Rocket Race, Starlord from TKS, Bassline and the like) which one would you pick? I'm guessing 1102, 1003?

[@NickBurnsFPV]

I would likely use the starlord as it has the prop clearance to use hd video systems.

[@ivanluhi]

@@NickBurnsFPV thank you for your help!

[@KOFPV]

I've gotten to the point where a lot of days. I only eat dinner, maybe a snack also. I kinda go through phases. Sometimes, I want to eat constantly. Usually not, though. Unfortunately, that doesn't make my tummy go away. Lol

[@NickBurnsFPV]

eating when hungry, rather than time is likely a healthier way to fuel.

[@KOrnhOliO1]

Eating an only meal for dinner is not what most will recommend. For one, the brain needs protein when you wake up after sleeping all night. Your body functions better when you eat breakfast. Remember the ole saying "Breakfast is your most important meal"? Yup, that's why! Lol It's not healthy to go to bed with a full stomach. IMO, the best way to go about eating less is to eat a good breakfast so you have something in you to carry on about your day. Then, maybe a snack for lunch if you feel hungry...an apple or other fruit would be perfect. Then, eat an early dinner. Add a good walk after dinner to help digest your dinner and work off some of it. By bedtime, you'll probably not feel so full. Eating late dinners, big dinners, or dinners with later late night snacks actually promotes weight gain because you have all of that food in your stomach when you are typically the least active... Nighttime TV watching or relaxing, then going to bed with all that food still in your stomach. Anyway, my wife is really into nutrition and late night eating or eating your only meal for dinner isn't the best idea. Probably will sleep better without all that food in your stomach, too. 😉👍

[@KOFPV]

I eat when I am hungry 😋

[@NickBurnsFPV]

@@KOrnhOliO1 Its about what works for the individual. Your wife might be interested in some Andrew Huberman, neuroscientist, content He is very into health and fitness. I stopped eating breakfast as I found mental clarity without energy deficit. Check out "the history of breakfast is the most important meal of the day". When I looked into it after finding fasted exercise studies, I gave skipping it a go. Some of the reading is very interesting, like many things in today's world, the articles are not only about what they say/claim but also what they don't.

[@yesil1026]

I wish I could fly like this. When watching here, oh I can do that, when flying myself, wow wow too fast, I either fly like half the speed or I crash. and my backyard is very similar to this.

[@NickBurnsFPV]

It just takes time. We all fly different, best to just enjoy each flight. :)

[@armanfaraji5674]

Hello, my friend, I have a problem. I did everything you said and it was great. In the last step, I can't connect the drone camera to my HD zero glasses and have an image. What settings should I do? Is it possible through your VTX?

[@NickBurnsFPV]

Are you using the scan function of the goggles? the goggle should scan and find the video signal if the vtx is powered on.

[@boccatxrx5023]

Another thotough review, i can always count on you to inform me Mr Burns, thanks for your hard work👍🏼🍻 So this little guy isnt top pick for acro type performance, what 2s HDZero would you say is the most agile and rippable? As always, I appreciate your work mate, cheers💪🏽

[@NickBurnsFPV]

I think the bassline is definitely one to consider, likely one of the top 3 I have reviewed if not the top BNF I have reviewed in the category.

[@dr0n3droid]

Put OSD on a switch.

[@NickBurnsFPV]

yep. there is a mode for OSD ON/OFF

[@FIGFPV]

Hi Nick How do you find this flys compared to the nano baby 20? I prefer the design of the frame on this but that capacitor hanging out back looks a bit exposed for my liking. Hope you and the family are well. 😊

[@NickBurnsFPV]

If I recall correctly the nano baby20 I reviewed was analog so a weight advantage there. With that I did prefer the way the nano baby flew over this one

[@Mupshot]

Curious how they wired up the 2s walksnail board to a 2s machine. Moblite 7 HM used the buzz+ instead of the 5v pad next to the ground and UART. figured there must be a reason for using it.

[@NickBurnsFPV]

They wired the power to the flight controller vbat + & -. Not the battery led pads but separate vbat pads.

[@Mupshot]

So potentially greater than 8v vbat? Or is it 5v. I'm anticipating the new snail 1s board to be officially out soon since walksnail kina doesn't fit 2s.

[@NickBurnsFPV]

@@Mupshot The silscreen on the board says vbat, that would be the same as the battery voltage. In a 2s case that would 8.4v or less as the battery is used.

[@Mupshot]

@@NickBurnsFPV thank you sir. That makes me think they are getting the new 3s capable snail boards. I'm excited.

What microphone were you using through the hdzero goggles? 🙏🏻

[@NickBurnsFPV]

two things. I only ended up using the mic flight audio in the last flight footage. As noted on the screen I switch to cell phone camera audio in the main flight. The mic is a purple panda, they are kind a generic producer of things.

@nick burns Im following your 3 changes video diet.. slowly dropping the pounds (whilst also riding my bike again), feeling better for it. hows it working out, does the weight stay off or does it creep back on?

[@NickBurnsFPV]

I suspect for those of us with a tendency to put on weight it’s something we have to be aware of. Rather than it being a diet, a new way of living. After we have achieved our desired weight we can bring the calories back up some slowly while monitoring the weight to find a new maintenance way of eating. The exercise is good for our health but doesn’t burn as many calories as we might think. For me I have found it better to be more mindful of the food intake than being excessively ridge on an exercise routine. I have experienced weight ups and downs. I find travel to be the most challenging and scale disappointing.

[@doccock100]

@@NickBurnsFPV thanks for spending the time responding. Holidays away are the worst. I can't maintain what I usually do and then don't want to get back on the scales after. By the time I do, much damage has be done. Denial is a terrible thing. On the bright side, my quad seems to fly the same no matter what weight I am.😂

@@chickwithstick7695 I don't believe there is. I have my dvr set to auto record. When the goggles detect a signal it records without any input. Curious yours doesn't show the red rec icon. By chance did you move the goggle osd elements around...I think that is an option.
