as the 250g rule in some countrys does change the market and we allready have good support for 3inch and less, it seems as a sign there is a nice 4nch pnp model on the market. ironc thing for me; its named „toothpick“ xD
when will the first 7inch“toothpick“ or xclass“toothpick“ come on the market xD everything is toothpick xD
it looks like a nice 4inch quad to me

LOL and I just completely deprecated my 3 inch drones in favor of new 5 inch builds. What timing baha.

GEPRC are banging out quality micros like there's no tomorrow. The 3-inch GEPRC Skip is another top micro (HERE). Way too much choice in the PNP/BNF micro world now. Maybe that's a good thing, but which one to choose? 

However, I do have to take issue with them labelling the 4-inch GEPRC Dolphin as a "Toothpick"

Actually Banggood are calling it a 'Tootkpick'. Apparently copy-pasting product details is too bourgeois for the PRC. You must re-type by hand, comrade!

I've been using GEPRC motors on my 5-inchers for ages, and on my new toothpick and they're solid. Although I have no idea who actually makes them - RCINPower, maybe? The bells look similar.

Well...from some angles it looks a little "toothpicky"...?

Still, the acceptance and marketing of micros has certainly expanded since I first flew them almost three years ago.  You are not kidding about "which one to choose"!

Happy new year, BTW!  You will get there ahead of me by some 8 hours.  Hope for you the best in 2020, for all of us!

Wow...over 5 minutes of flight time on a 750mAh 4S LiPo with 14.6V still remaining in the tank. I bet that would be 6 minutes if you took it down to 14V. And under 250 grams as well, so a 4" quad that doesn't even require registration with the FAA or CAA   



EDIT: And an earlier review by Justin. Still under 250g with an 850mAh 4S LiPo...

That is exciting, no doubt!  I like the smaller quads more than the larger siblings (though I actually like all of them )

Have thought about building a 4" this year and every time I see the awesome performances they seem to produce it strengthens my resolve


Thanx for sharing the vids, Snow!

Yup, 4" is the new 5".  I'm planning on building one and have already done the math.  Pretty easy to get one under 250 grams.

I thought about building something as well but the prices these pre-built micro quads are coming in at, I think you would struggle to build something of similar a quality for anything much cheaper. I have the GEPRC Phantom which is a really well designed/made and I wouldn't have been able to build anything better myself for the price I paid for it. I'm quite tempted to pull the trigger on one of these and save myself the bother of building.

The only downside is that it seems to be a Banggood only supplied product again and they are stating 22 days processing time, which is basically the standard processing time they usually put when they have no stock and no real idea when they will be getting new stock. I've already been there before and got the t-shirt which was a frustrating experience that turned out to be a 6-8 week wait before I got my items. Plus it's Chinese new year soon so any delay will just end up being extended by a few more weeks.

I've been a big fan of geprc since I started FPV, My first motors I bought were the 1408 3600kv that to this day still run as if they were new.

I was actually planning on building a new 3 inch quad with them since i fried most of the electronics on my previous 3 inch. Now I'm leaning towards a 4 inch, should be able to run 4inch props on 1408 3600kv right?

yes they should spin a hq4043 easy, i flew them on my very first kingkong 1306 3100kv and their working now over about two years... the uaw is very important to the performence you will get...
my was 130g and the battery about 70g(?) and the performance in specific area and handling in general was still unbeatable over all my quads i owned today.

i saw the video of kabab and still he is telling some theory about 4inch, declarated as an opinion...
as i see this and saw in the past when he start to suggest nanoquads, his „own“ concept which already exist as a pnp to buy for every beginner....
i have to scream somewhere: kabab dont know how to build quads! he is going to be a complete marketing joke... he should draw frames, where he has some knowledge.
as he started to sell all the variations of nanos, from the tp1 to the tp3, declarate them as his own settups. he stops at 4“ and tell its a bad size... and this will affect to the market, as the is nanoquad market is grow up in „shine of kabab“
a lot pilot didnt notice that nanoquads are nice, they needed the „shine of kabab“ to enter into the nano pleasure...
kabab tells 4“ is a bad size and 6inch is a bad size, only someone who dont understand building can declarate a propsize as bad in general...
4inch has so many potential and today, the time has changed, the ability for quality parts with a fair price in a good weightrange are possible... and they would beat 5inch quads in performance fareaway, there was a technical reason why 5inch start to be popular and there is a technical reason why 4inch should go popular over 5inch today. 6inch has still the benefit over 5inch on highspeed tracks and 4inch on technical race tracks... i dont know pilots which fly that mixed tracks that a 5inch would be the best.
as i saw the improvements over the nanoquad marketsupport, i see the bad influence of his unknowladgeable words about today. i tought he would going to declarate every propsize as his „own settup“ but he stops at 3“.
where is the knowledge about building gone and why is there so much „shine“ which stear the market
im pissed about how the market turns with shiny yt influencers...

4inch accrelate faster and decrase speed faster than a 5“, its more nimble has better turn-ability... the only thing which speaks again this; a fast quad isnt easy to fly, a fast 4inch quad is nothing for a beginner, like an ultralight 5inch. they are to fast for regular beginner pilots, it seems like beginners stear the direction of the market for racingquads

its very sad fullspeedrc/namelessrc start working together with kabab, they sell all the concepts as pnp befor kabab „invent“ it and kabab says in his video they use „his concept“ and they should have at least one person in the company who understand building; they have at least one that understand a lot more than him, fullspeedrc should earn the honer about microconcepts, in this term kabab is a rober of ideas, a robber like he tell about other companys.... happymodel bring out a lot more nice micro build concepts aswell, some quality issues but compared to the proce and inovation still fareaway from „kababs toothpick inovation“

The hq 4043 were exactly what i had in mind with a build as light as possible. If anyone has frame suggestions, I'm very open to them. I planned on designing a 3d printable frame for it because well that is what I love to do. I've flown many 3 inch printed frames which fly fine but obviously are less durable so a good carbon 4inch frame would be a nice find.

I understand your feelings about kabab even though I'm a bit of a fanboy. I don't think he's saying 4inch is a bad size but for most people it's more logical to go either 3 or 5. 3inch for somewhat silent toy looking quad can you can fly more places or 5+ for your gopro carrying cinematic setups.

Maybe all the stuff he's sharing an theorizing has been done already but he is the one making it public or at least WAY more accesable knowledge and working with companies to get us better electronics, props, etc.

I don't think he owns any size for that matter but just like any other fpv company he brands the stuff he comes up with whether original or not.

i didnt try but emax avan 4inch props 4024 and 4028 are new on the market, i will try them aswell.

rotorama spirit is a nice 4inch frame, droneart has a beautiful 4inch frame, not a lot of space to build....
dave c has a new gatehunter x frame available, normaly for 5inch but new with 4inch arms, made for 26x26mm electronics like the geprc.
as a tanky 4inch i used a diatone gtr4 frame, its about 45g heavy.
my 4inch frame over the most time was diatone grasshoper 160, very old framedesign - but 30g lightweight.
kabab did a floss 4inch frame, this was something good from kabab ;-)

if you are looking for use 26mm electronic aioboards, i personaly would choose a gatehunterx 4inch version. i guess the 5inch version is available from armattan, probably you have to ask amattan specific and order and wait for the 4inch.
the spirit is my choice for 20x20mm.
rotorama has a new 4inch frame, a shrinked 5“samurai to 4inch...

this was kababs floss 4inch video and sadly there was absolutly no improvement in the market seems than, still no propchoices ;-) i am crying


about batterys... 6s is available for 4inch aswell, this solve the bad market support in this battery sizes - if the uaw of the quad is heavy and 4s 850mah sag...
there isnt a 26mm aio board which can deal with 6s, but for very lightweight builds hglrc has a 16x16mm 15a stack 3-6s, its not available separate at the moment, but its in the hglrc parrot136 5-6s pnp

as gopros are more lightweight today, they wont destroy the flightcharacteristics. 5inch is a tradition today qnd not benefit based in my eyes. in the racing league in my area less than 5inch propsize isnt allowed, but up to 7“ xD and they fly only technical tracks and not one highspeed track... 4inch is set to sleep by different factors

Excellent info! Making a thread for my build tonight, have some more questions and need of advice. Hopefully see you there! ??

Going to go with the rotorama spirit frame I think.
