WOW! They're very durable! I've been flying J37 for more than a year. I'm going to order the Gemfan later and do a flight test in the next few days. Thanks for the real test review!
4.9” is a great size, especially on the lighter builds, I love the spool… I hope people try them and realize how much fun 4.7-4.9” is… and we get some more wide releases in the size range… it’s one of my favourite! I really love -4.9” tri-blades for quick trippy freestyle and 5.5-6” bi-blades for flow style… I wish people were more open to trying new stuff, it will drive actual releases and development. We are a little stagnant at times, and have so many motors and props that just don’t get released, because of the lack of interest 😢 or see a single generation and just get dropped… I feel like when the cool new stuff get released, people just look at the numbers and get confused because it’s not a 2207 or 5” and don’t give it a chance… even though it is awesome… I dunno, sorry for the tangent. Happy flying everyone, please experiment more, and we will have so much more cool stuff.
No problem ... The thing with motors and props is this... And it's what you are saying... There are a lot of variations and combinations to try to find that perfect setup for someone. And the thing is, it doesn't matter what someone else says or what something was "designed" for, it can fit a variety of scenarios. Look at me for example .. Flying props designed for a completely different setup and different flying style (though I have my sbang moments) and they are working for me exactly like I want.
@@StacemanFPV absolutely agreed! People may find that they much prefer a very different feel to everyone else! That’s why experimentation is key! That was the driving force behind a comment I made yesterday on edrones community post on props. Props are the easiest to change and make the biggest difference, it’s cheap and easy to experiment with props and everyone should try as much as they can get a hold of… motors on the other hand aren’t AS important, they either control the prop properly or they don’t… I like very specific stuff, and I also change my torque curve, in radio, with a data crunching spreadsheet to calculate my exact curve to give me a perfectly linear motor with a 5% hover point… this gives me absolute perfect throttle resolution, repeatability, and transferability between vastly different builds and motor torque curves. Not many tune their torque curves (but should) and rely on finding the motor that fits them best, when they could just be tuning the curve on a motor they like the durability or other feature of. 🤷♂️ am I weird? I design motors, of course I’m weird 😜 I generally run 9-12 points on my throttle curve to get it perfect, I go for linear, but a friend of mine likes to go for an artificial fast ramp up and bump… that’s the wonderful thing about throttle curve tuning, make it feel how you want! Can make the quad feel completely different. Again with the tangents 😜
@@lemonsquareFPV yep you're weird LOLOLOL but in a good way :-) 😂😂 I don't think I've ever heard of anyone tuning for the motor torque curve.. I think Bob Roogi is one of the few who even talk about it and how it affects things.. Puts you in good company I think.
@@StacemanFPV LoLoLoL! 😂 Thanks man! Yeah, I need the precision for my kinda flying, I can’t afford to waste a third+ of my throttle stick for nothing, thus the 5% hover point at the bottom of the stick travel and perfect throttle = thrust relationship. Also some setups don’t make more thrust above 90% (number just for example, actual may be higher OR lower) and just pull silly current, kill battery, and heat up the motors for zero actual work done… so that’s a good place to look to optimize throttle too… I over engineer and optimize everything, and sometimes it really, really matters, and sometimes it’s a waste of time 😜
I've got the Gemfan Vannystyle props on the way. I've tried numerous variations of props and usually end up back on the Hurricanes. Gemfan is weird with the naming vs pitch on the Hurricanes. My favorites, the 51466 are 3.6" pitch. WTH, verified on their site. All that matters is that Gemfans rock. 😎
I fly 6 s on my roma f5 v2 and yes it heavey, the tattu funfly 1550 is heavey and it transformed my drone when i put the dal 5045c pros on, when i first saw them, i was like jesus man, there fat, so much blade coverage! I gave them a go and immediately fell in love with those hunking bits of plastic! People knock them, and im not comparing them to thrse props youve mentioned, i just wanted people to know that the dal 5045c pros are so punchy, the hub is like 6 mm and the seem to give more control at below middle throttle ,i suppose its cause theres no bounce back from the heavier drone. thanks #RC_ADDICT
Be interested to see your findings we’re all gemfan here except for used quads we get with other brands.. also pigment and Dye does play apart in the brittleness or flex of a certain plastic .. most are inject polycarbonate
@@StacemanFPV blues can be brittle .. back can be to supple .. and like all thermoplastic are susceptible to moisture.. so humidity also plays a part. Opaque colors seem to break transparent seem to flex .. gemfan did talk about this in a few live streams.. message Mike from gem fan he will give you a answer asap
The Gemfan clearly more durable than the HQ. After those crashes, I was expecting them to look a lot worse. Flew pretty good for the damage they took also. Thanks for the video.
Okay, I lied in the chat. My 5" quads are closer to 580g with the naked GoPro's and my latest 1500mah 4S packs, lol. I used to run lighter 1100-1300mah packs, but didn't like the flight time.
Yeah, very similar to what mine were a long time ago when I ran basically no TPU, used a GoPro Session, analog, and flying a slammed martian build with really light RDQ motors and ethix water melon props.
HDZero looking crispy. I love less aggressive props for proxy actually, not overpowering gaps, LOWW prop wash as well. Youll probably love the GF 4937.
What's the benefit from running an underpowered drone? I'm running 4s black birds on tmotor 5.1x4.3 props. It's screams but am I missing something? Should I try 3.4 props?
Well, it depends on what you are doing. For me, underpowered works really well as I like to fly a lot of tight proximity flying. Being underpowered basically gives me a lot of throttle resolution, which helps to prevent ballooning or over-correcting throttle adjustments. If you fly a lot of open spaces, then underpowered is not what you want, but many sbang pilots like these props on high kv motors for their response as they make a lot of quick direction changes, and need the prop to provide throttle very quickly, and don't necessarily need more thrust as they run higher kv which compensates for less thrust of the prop.
@StacemanFPV I have a quad for open spaces and I'm currently working on one for tight proxy. I'm gonna try out some lower pitch props. I have some 4.9x3.7 that might work good for that. 2500kv 4s
came here for a prop review, found a gnarly pilot!!! sick flying bro! thanks for the review!
Awesome! Thanks for kind words
Glad you liked them my dude, Sbang is the way! Keep it up bro! Cheers, Mike.
Yeah good props..I ended up settling on the HQ ones but still like the 4934's and have plenty of them
Yes the Gemfan sbang ar the best. So durable it is amazing. All my friends fly the sbangs.
They look to be durable so far
WOW! They're very durable! I've been flying J37 for more than a year. I'm going to order the Gemfan later and do a flight test in the next few days. Thanks for the real test review!
Enjoy!
@@StacemanFPV Will do. It's arriving on Tuesday :)

@@lemonsquareFPV ah but that's some of the fun in figuring out when it was worth it and when it wasn't
Those props were screaming 😱 gud stuff stacey
Thanks buddy :-)
I need to move somwere were the weather is fairly gud all year round this white stuff on the ground is killing me jonsin to flyyy lol
Man I know the feeling ... When we lived in WV we had that awful dandruff all the time :-)

The vanny props are great but yeah I don't get the size and pitch designations either.. They are all over the place
I just got a whole bunch of J37's and I'm on my last set of Sbangs. Aaaaarrrrgggghhh!!!!
Maybe they'll be alright for ya.. Hopefully...
@@StacemanFPV as long as I'm flying I'm good but I'm glad I have a trunk full of salvageable sbangs. 🤞

There's lots of choices for a lot of combinations for every kind of flying people want to do
That's funny I just did a little test session video on the Gemfan Sbang 4934. Been flying them for 2 weeks now and I love them.
Seems like I remember you mentioning that on insta
Be interested to see your findings we’re all gemfan here except for used quads we get with other brands.. also pigment and Dye does play apart in the brittleness or flex of a certain plastic .. most are inject polycarbonate
Yeah that's what I've heard, though I don't have any good science on it
@@StacemanFPV yeah I have cast resin and form poly carbonate.. and color’s definitely come into play
What have you found to make the biggest change in weakening? Any particular color, or just color in general?

I'll reach out to him. thanks
I only use Gemfan 51433 hurricane.
I’ve tried almost all the props out there 😂
that was my go to prop for the longest time. still like it.
I love the Gemfan Spang props and the Dalprop N2
haven't used a DAL prop in a LONG time... used to be my go to prop brand way back in the day.
The Gemfan clearly more durable than the HQ. After those crashes, I was expecting them to look a lot worse. Flew pretty good for the damage they took also. Thanks for the video.
I gave them another beating today and continued holding up. You'll see that in my next video.

Might try those... Just a little more thrust than these but still nice and underpowered for that proxy fun
great testing brother!
imma have to check the gemfans out now lol!
I've only flown the one pack, but I like em. Going to fly them more today.
My best props are the ones i havent broke in the bottom of the bag
Lololol good one!
I've bought the sbang and juice props but the sbang only came with the CCW so I'll mix both of the props lmfao
Lol yeah they were weird with selling them that way
Gemfan and I didn’t even watch it yet 😅

Yeah those would be great
Would you recommend 4s?
I've never had a reason to use anything more than 4s
