Absolute best 4" prop. Game changer. I was so sick of those DAL props breaking that I stopped flying it for awhile. 4" is a ton of fun very different experience IMO. Thanks for the great reviews.

Dang, almost done building my 4” on 3800kv with these same props and same weight. Didnt think it would rip this hard! We shall see, now im excited😎

[ponyboyfpv]

I just tried this prop today, and it is amazing! By far the best 4 inch prop I have used.

[mcqueezi]

i really like it when you tubers record what they see instead of what the go pro sees because it gives us more of a grip on what it really looks like

[simonmussbacher]

You really make very good videos and you get better all the time

I've just flown a 133g 3 inch on 4s with rcx rs1407 and I'm a bit shocked. It's bloody incredible. The speed at which it changes direction is insane, this thing would leave any 5 inch I've ever flown for dead on a tight course by a large margin. Oh and it happily carries an action cam... Problem is it shreds batteries. Neither Tattu or graphine 850s can cope with it. Going to have to go larger or enjoy 2min flight times. These 20x20 stacks are really bringing these superlights back into business. We so need better batteries!

You're like one of the few guys that has good prop reviews.

[gitech]

Wow awesome! Now I need a 4" Floss! :D

[bxkwad]

that little 4'' looks like a lot of fun :)

[drippingice]

This channel is so good to learn about mini quads

[SpoonFPV]

I am so pissed you got this before me. I talked Zhong into making this, and you and others got them first. Glad you like it.

[MHRlabs]

I love 4" but the previous available props sucked. Was on the fence on this prop until someone reviewed. Thank you for the review!

[CrashNBurnRacing]

About time a good 4" prop comes along. I have a 4" build on a custom frame that i designed that weighs 268 grams with 1407s on a 4s 860mah that I have been running on DAL TJ4045s. These props look like it would be a good improvement.

[skylerallinghamgotime]

Yes the Dal TJ4045 rocks on 1407 3600 kv on 4s

[JRIPFPV]

Man I have been waiting for a good 4" prop forever! Great job HQ.

[CoppertopFPV]

Music to my ears. I've been running Dal 4045 v2 as I hate those hq and dal twin blades. They like to explode. Please let us have them in the uk. Also, rcx rs1407 are seriously good motors. Kick the BH into touch. Also trying the cobras which seem very good. You've got some major competition from Avantquads with this sort of setup. They're my 4 inch of choice. Love em. 245g auw with 850 Tattu 4s

[Bertoslav]

I was running 3 inch props on my 4 inch frame for less power (my first quad, so I wanted to be carful.) I got a couple sets of these, and omg, there insane with 4s compared to my old 3s 3 inch prop setup.

[EverythingNaus]

Just got these in the Mail today from PiroFlip, will be testing them on my 4in Kinetic Aerial Air-Ro frame 225g  AUW race,  and my 250g AUW freestyle version. I think these props are going to be amazing!

[odinnfpv]

Awesome :) NEED those props. Im not an fan of the run cam split but that would probably work on this setup. If I would have done it, an Foxeer Monster v2 and an HMDVR onboard would have been the solution. NOT HD video but as good DVR you could get and edited right it would look ok for most. Love that HQ made this, a step in the right direction

[Bexamous]

Yeah I wish the 5" V1S was a bit stiffer.. even with 2204/3000kv motors when motors really unload at very high end of rpm you can hear props starting to sound awful. In general I find the combo awesome though, I actually really like that low end pop they have. But I wish there was a stiffer 5" V1S for like 2306 motors on 5S type of setup.. like 2650kv+5S high rpm props are like unusable they resonate so bad.

I got the 4" V1S sitting at home though.. looking forward to trying them on some 1407 motors. Would make sense smaller diameter would let them handle high rpm much better than the 5".
