" Entry for SpeedyBee TX800 VTX " nice video brother.

[@AlbertKimTV]

[@HotboiEngineering]

The phenomenon you are talking about @ around 7:30 is aerodynamic drag and cavitation. Max prop tip speed is 450mph, past that the tip vortex and turbulence on the trailing edge become too much and detach the airflow from the prop surface and cause extreme drag. You can brute force past this, but you'll have insane amp draw, vibrations and reduced performance so its not worth trying.

[@AlbertKimTV]

One thing I forgot to mention is that the low-end torque is intense on this. Super locked in when making direction changes. That could be the unseen benefit here.

[@SensorDelay]

This is so sick. I can't wait to get my pre-order.

More power 💪😎 Was thinking those motors look like they belong on a 4 inch. Diatone makes some great stuff at reasonable prices , very happy with their stacks. Only concern I have is break an arm, it's a big deal . I'd rather have replaceable arms. It's got plenty of motor to lift the little bit of added weight. And it's already over the 250g arbitrary weight limit. Thanks for sharing, happy flying Albert 👍🤓

[@AlbertKimTV]

Thanks 👍

[@flyfpvfish4962]

Nice review 👌.. that's a small beast.. so the props are giving the motors a limit.. different prop more speed..

[@AlbertKimTV]

Yes, the small prop can only do so much. Imagine even a bigger motor with that small prop, will it really go any faster? No... However, the advantage is on the low end of the throttle with a massive amount more torque to control the tiny prop. It was super locked in.

[@CraigValadares]

Because the 250g limit does not apply to the rest of the world except usa.

"Entry for SpeedyBee TX800 VTX". Yesterday I installed the Free version of the Free Rider Fpv simulator and I had a great time practicing with it. I thought it would be as easy like to fly a toy drone but after 10 seconds into the simulator if felt that it will suerly take a minimum of 3-5 months to get to a good flight (very hard). When I watch your videos before, I thought Flying FPV Quads would be easier than you say but know I know that it needs skills to fly them. But with good practice I will suerly fly beautifully as you. Man, you are a legend in Flying Quads and your videos suerly deserves a like 👍. Great work man and keep doing these reviews and giveaways 😛😀😀

I think the 1404 on the smart35 are just fine. Dont need more power than this - still feels capeable as a freestyler. this quad here just looks a bit to "american" while it's chinese ;) (a lot of horsepower, not very efficient - sorry 'merica ;)

[@AlbertKimTV]

I disagree. 1404 is just too small IMO on these 3.5 inch micros. I've said that since the Babyhawk II HD came out. Finally they are starting to listen to me, but Diatone has taken things to a serious extreme. 2203.5 is overkill. Way too much power for this little guy but I think a lot of people will love that kind of power at their disposal. Sometimes flying has to be more about the FUN factor than being optimal and efficient. For those guys, I'm glad something like this exists and I hope the other factories are watching and learning from this. Please bring out more fun stuff please!

[@Rcschim]

@@AlbertKimTV Agreed! Fun should be number 1 prio! DaveC also said in a recent video he thinks the 1800 motors would be a good fit for this class. he also didnt like the Babyhawks performance too well... I can only say that I really enjoyed flying the Smart35 alot over the past 2 month. exited for more frames in this class. greets!

[@AlbertKimTV]

@@Rcschim Nothing wrong per se with the 3.5 micros with the 1404 motors. They are very capable fliers but just doesn't have as much of an excitement factor that the bigger motors will bring. That's all.

[@gvngoheavy]

The disparity between sales data and voices online is very very present in the cycling world too. Everyone says they want 26" or 27.5" mountain bikes but whenever we make them they dont sell. That said theres a legality issue with the 250g thing that brings in a different aspect that Im not totally sure how to calculate for.

[@gvngoheavy]

I dont know whats going to happen with regs and enforcement down the road just like pretty much everyone else, and I think the assumptions you make about that future really drives your current perspective. At the moment Im leaning more and more towards the regulating bodies relaxing and the whole thing becoming a non-issue. Mainly leaning that way because of the failures in the drone delivery services sector that were in the news the other week. From my perspective that has been the main driver behind increased scrutiny by the FAA. The big corps want the airspace for things like delivery drones, so they sold it as a safety concern. Its always about the money.

[@AlbertKimTV]

That legality aspect is quite ambiguous at best. Most people don't follow the rules anyway and just ignore the limit. It really is a SMALL number of people who make these demands and then force their preferences on other buyers who then decide not to buy it because it's not what they want. So the manufacturers keep asking why they don't sell. I tell them, that the weight limit makes the quads basically no fun and who wants to buy "boring"? I think this is why Diatone is going back to making fun machines. It's a good thing and those guys who want to obey 250g limits can still keep on building their quads like they always have.

[@remotecontrolaholic]

Entry for SpeedyBee TX800 VTX Looks like a fun quad, but I feel like those arms would break real quick?

Completely agree with you I won’t even follow the 250 g limit I bought the mavic mini and got bored with it after about two flights, also anytime I fly a bigger drone I’m never punching it up into the sky causing hazards to the faa (5inch>250g)

Hey man, what do you think about the 40a esc on this thing? For a 6s setup with peak current at 15.59a/motor, shouldn't a 60a ESC be used? I'm still learning which components will go together

[@AlbertKimTV]

The ESC is rated 40A continuous 55A burst PER motor. So 16A per motor is NO PROBLEM.

[@SpikeJonesTheCr0oked]

I don't know if you follow Chris Rosser or not, maybe you just have really good instincts due to how long you have been testing quads and the sheer number you have probably flown by now.....but long story short he has done a lot of calculating and graphing and such and his data seems to indicate that the 1806 motor would be the best choice for 3.5 to 4 inch props. Your hunch seems to be right on the money

[@AlbertKimTV]

Sorry, I don't know who that is. I don't watch any other channels or follow other people. I purposefully avoid that so my opinions aren't polluted with the ideas from other people. Yes, I've flown thousands of different models and I'm able to make some basic judgements about what would work based on just experience without a lot of prior testing. But at the end of the day, it all comes down to a subjective choice. What one pilot likes may not be the same for another. Each set of specifications can yield different results for different pilots. This is why we need a much larger choice of parts and designs rather than a smaller number. I feel like there are certain forces at work where only a limited number of people want to be in control of what gets made and what doesn't and this is actually bad for FPV. We need more diversity, not less. Why is the standard 5-inch freestyle frame still the only one most people fly? All 5-inch frames are just clones of each other. Nothing special. Something new and different comes along and all the lemmings immediately try to kill it off before even trying it. What's up with that? Sorry for the rant...

2004 size might make it more efficient but without actually testing that size with this prop, it's just a guess.

Not all drones have to be the same. Variety is good and a lot of people like the super light designs and will still buy those even at the expense of durability because they have different priorities.

I've been building my 3 and 4 Inch quads with 2205s 2300kv for a while now 🤷 it's a blast and it can carry a gopro9

[@patricksharp3355]

what 2205 do you use

[@boskan89]

Nice quad. My personal opinion is that there is noo need to go with ovepowered setup if it can't be used in full potential. Oh, and Entry for SpeedyBee TX800 VTX

[@AlbertKimTV]

This one is for those who don't care about that stuff and just want something FUN to fly. It's important for these companies to realize that FUN is something people want too.

[@battano]

Looks close to a 4 inch flouride with 6s 2303.5 motors build coming up once I get two micros out of the way. Going 4 inch with it but plan on running the HQ 89mmX8 props un-ducted hahah Its going to be wild. You need to get your micro 6s lipo supply built up man lol

[@battano]

all the 6s micros Ive run from 1106 on up do not increase speed or performance over 4s but you do increase your flight time with 6s done right.

Awesome review, Albert! 😃 Pretty insane little quad!!! Stay safe there with your family! 🖖😊

[@AlbertKimTV]

Thanks 👍

[@Przemo-c]

Damn it's a heavy one for 3,5 inch. But I like diatone. My GT R-349 serves me well. I love smaller but powerful quads. And I like smaller lighter toothpick and tinywhoops... hell I just like small quadcopters :-)

[@AlbertKimTV]

You'll like this one too

[@Przemo-c]

@@AlbertKimTV do you think there's a big difference between 4s and 6s in that quad? I find 4s on 349 more than enough on 3140 props

[@artifixprime]

Most of my flying is in local parks where there isn't too much space to keeping things under 250g gives me the most freedom while staying within the regulations if I was ever challenged on it - nobody has to sate, but I'd rather live with a smaller quad than lost the ability to fly. (Entry for SpeedyBee TX800 VTX)

[@AlbertKimTV]

FYI, i've seen people flying smaller and lighter then 250g quads get in trouble, get fined, etc. It's not really that safe. Most cops are totally ignorant of the rules.

[@artifixprime]

@@AlbertKimTV You're not wrong. Also, I should really re-read and check spelling before posting :)

Efficiency? Imagine they have some 1804 Mambas in secret release.

[@AlbertKimTV]

Perhaps soon!

[@karoo_bushman6880]

I like the 1408 for my 369 more :P inefficiency and speed!! ting goes brrr

[@EricLaermans]

Is it of any use, high-torque motors, small props, high voltage (6s)….? And what will the flighttime be?

[@AlbertKimTV]

Who cares when it's just FUN.

[@EricLaermans]

@@AlbertKimTV Well, if one picks any quadcopter, is this value for money or is there a quadcopter at the same pricepoint which is better balanced out (looking at the overall setup).

[@mattdallas5671]

Almost 7:1 seems like bad news. I purchased 2204 to try and hope they do well.

[@AlbertKimTV]

What does 7:1 mean?

[@mattdallas5671]

@@AlbertKimTV It is a diameter:height ratio for the motor. Typically large flat motors have a high MOI, and don't perform as well as a taller, more narrow motor for freestyle pilots usually in the lower throttle range. That's my understanding, at least.

[@Catiadr]

You mean that the noisy minority doesn't rule the quiet majority? Hmmmm... Perhaps a bit more pitch on the prop would help.

[@AlbertKimTV]

Or does it? Hmmm... 🤔

I'm waiting for a review from the new diatone F4 that just came out,looks like f35 with longer arms and different Motors,

Yep, should have that one any day now!

@@AlbertKimTV I was hoping you were going to say that since you're like the first person to get stuff from diatone, and of course I like watching your review LOL

[@angelrojas4620]

A couple of mentions: Ive heard with the scarcity of resources going on BNF are sometimes being used to source parts. How do you think that would drive sales? Also, the F35 seems perfect for freestyle in areas that might be too small for a 5", cheaper too. Lastly, Entry for SpeedyBee TX800 VTX

[@AlbertKimTV]

The supply chain problems are a more recent issue. Not enough data on that yet but I'm sure it's messing up a lot of things all over the place right now.

[@dronesbikesboards5017]

Have. You done any durability tests?

[@AlbertKimTV]

Durability tests are worthless because there's no way to duplicate a crash and there's no standard for how to achieve a test that makes sense and has any integrity. If you know of such a way please advise.

[@dronesbikesboards5017]

@@AlbertKimTV that makes perfect sense. The only type off "durability test" i can come up with is just using a drone for a long time and seeing what breaks. For instance I've had a basher for a about six months now that I've flown 800+ packs threw and have pretty much replaced everything except the motors. (Emax eco 2 series 2306 1700kv) motors.. and somehow they are wonderful still. But in the end thats more off a longevity test. So you are right.

[@rallygaard]

""Entry for SpeedyBee TX800 VTX" Looks interesting!

[@jayqfpv6835]

Motors are way to big and heavy. Stupid decision for a 3.5 inch. Put some Xnova 1804 motors on it and It will be a rocket ship and handle way better. Anyways.. Great review as always

[@AlbertKimTV]

I guess time will tell if it was a stupid decision or not. I think it will sell well because people just like to over do things in excess... just human nature you know?

[@jayqfpv6835]

@@AlbertKimTV yeah true. And I guess people who buy RTFs are usually not that informed on motor specs and Quad theory in general. I think from a marketing perspective it's like selling a Tiny Car with a V8 engine xD

The thing is that 250 gram is not persee arbitrary at all, Its a Law problem, like here in the EU the cops etc loooove to go after the small people. And Fine people if they break insignificant laws like this.

[@AlbertKimTV]

Overall still a small market and you guys will end up building your own custom builds anyway. There aren't enough of you guys to justify a manufacturer to expend the R&D to create new models that don't sell enough.

[@techromancer6702]

if you want more speed above 80% throttle find a 3.5" 4 or 6 blade prop. you will no longer have that loss of power feeling @ 80% throttle.

[@AlbertKimTV]

Perhaps. You can't know that for sure, but interesting guess.

[@techromancer6702]

@@AlbertKimTV I mean, I can know for sure. just because you don't doesn't mean someone else can't.

[@AlbertKimTV]

@@techromancer6702 You haven't flown this model, how can you know for sure?

[@techromancer6702]

@@AlbertKimTV because it isnt dependent on the model but on the mechanics of props and how you gain additional thrust at the same RPM with different props. the model is irrelevant to the thrust the prop will generate, as long as the motor can sustain the changes in inertia.
