truly sad hype give the orientation, 2205 is a nice size.
my old zmx 2205 2600kv are 25g?, one of the most lightweight and solid motor from the past,would be nice if something near would come with about 20g per motor :-)

I've got some of these 2403 - 2300kV's on an old basher. Alas, 25g each...

probably these 2403 could do a efficiency job on 7inch prop, not worse a try for very long flighttimes as they are that inexpensive

Here's a lightish-weight 5" frame from FPVCycle (it also comes with 4" arms but currently out of stock): https://fpvcycle.com/products/fpvcycle-p...5712760943

Here is a new motor from FPVCycle. I just watched KababFPV's video on this new motor. This one is 5mm shaft, but they are coming out with a T-Mount version     I have requested notification when they get them in stock....another option for my pending 5 inch build. Yeah, might get that frame, too. 

AndyRC's review of the BrotherHobby Hyperbola. He wasn't overly impressed with it...

i dont get any issue from the propsystem, i didnt get any broken adapter.

i can confirm somehow, topend isnt great. i hide to use more than 85% throttle, not sure but it doesnt feel faster or more powerfull. i guess this depents mostly on the settup and prop, i beleive these motors could have a awesome topend on some skinny highpitch 4inch or 4,5inch blades - props which doesnt exist... i would probably like to compare a 2700kv version of this motor... i would like to try the dalprop 5051x3 but its not available for t-mount, to try a possible topend. i guess its a pioneer, need better marked suport to get very great in other discipline like topend.
the benefit i see is the pure nimbleness, for racing or speed corner flying. sadly andy didnt any fast turns, at least in the video, where this will be visable. probably he missed that.

he didnt mentioned the sound, silence

i gad one of the first hyperbolas, i thought its because of this, there wasnt any settup, it came default.
i didnt adjust the filters, i tuned the pid, i should try more but its enjoyable. i could share if someone need. this is truly poor for brotherhoppy, otherwise the benefits of this quad cant be used by a beginner anyway...

the canopy, yes it seems pla, its not usable as a crashprotection :-(

as its that nice in nimble turns, therefore 650mah is the fastest while 850mah is the biggest size i would use for any performence-flight - regardless about 250g. 650mah will decrease the topend even more as andy mentioned.

aaah damn, andys words have weight, i have to confirm its somehow unfinished about the canopy, this makes it not usable for any without possibility for 3d prints or 3d designing. the motor and prop combination isnt good at the last rpmvalue, but there arent prop choices....

andy compared the hyperbolla about speed with the diatone gtr3xx, sure faster. a better comparison would be the ditone gtm515, 5inch ultralight but not as lightweight as the hyperbola. i own both, the gtm515 isnt as fast as the diatone3inchgtr, the gtm515 is faster than the hyperbolla, it accrelates faster over the whole throttle area, the hyperbolla can probably hold up up to midthrottle area about accrelation. both accrealate fast overall. the gtm515 is very nimble aswell, but the hyperbolla is in another league. compared both to the fast 3inch model, wont be near as good on nimble turns, it will be much less efficiency... its a comparison of different focused builds.

i am absolutly lucky with my hyperbolla, over all. as i was looking for nimbleness primery from this ultralight, i realy get what i payed for. i would apreciate it would be more finished for other needs, but i still like brotherhobby joined the quad market an there is a true nice innovation. i hope there will come more ultralight parts and quads on the whole market, from various brands.

It looks like BrotherHobby will be releasing a revised version of the Hyperbola 5" which has some design changes and uses stronger carbon fibre compared to the original frame...

a buddy still ordered one, now the frame is more on the heavy side
seems a better frame for practice overall.

the prints are way too soft. much more weight than the first but much more rigid aswell. sadly it isnt "tight", it could carry 5,3inch props, there could be saved weight and improvement in rigidity aswell an yaw performance.
overall a nice unibody, somehow tanky for uaw of 230g with a 450mah 6s battery or 150g without battery.

the most difficult quad xD somehow a declaration of its unique abilities.
good pilots flew the hyperbola allready, but good pilots doesnt need to be good ul pilots. while an ul doesnt decrease hight by itself it needs to be onder load all the time, there comes nimblesness and precision. flown on a low throttle level, they are that nimble but only to increase hight, they are going out of controll. somehow the usual youtube reviewers in the 5inch class doesnt have the flyskills to handle an ul. they doesnt change their style of fly. there is a gap between micro quad pilots and miniquad pilots, there are the one flying ul micro quads and the ones fly mini quads. mini quads can be flown on a high level, generaly they are more easy to control, more forgiving. there is a pilot like mr. shutterbug or nick burns one the ul-micro side while a jb is strongly only on the heavy side. the interpretation in the abilities of products is as different as their kind of flying. personaly i would say the named micro ul pilots fly a higher level.
it would need a review of other youtubers to provide an impression about the benefits pf the hyperbola.
probably the hyperbola is a product for a very small costumer group at the moment.
i will need to cut a few corner combinations and u-turns to provide a view into the benefits, i didnt saw them in a review allready
hoping for a review by mr.shutterbug but seems he is in a tight cooperation with betafpv :-(

that 229mm hyperbola frame has obvious weak spots at motor holes - will likely snap there in a crash.
Also, remove material in middle and add sweeping "braces"... or nevermind, I just use my PodRacer.

but 229mm is big
its exactly the size you need for 6" props

FYI, the magic ratio number is 38.. so likewise 3" its 114.

Hi Roman,

Good to know. I will beef up my Hyperbola frame before I use it. Thanks.    

i broke the original hyperbola frame allready once, the one was sorted out by a buddy. the performance is better on the new frame version, its just the stiffness.

it was on 2s 450mah and 1306 4000kv with gemfan 5125, pretty lightweight. the weak point is in the middle of the arm:
