Yeah, i know "you can buy it as bnf/pnf", but i like to build. my gf calls it (german) "basteln", but that's hard work as we all know.

i never thought what a 16x16 stack is in size...damn small!

as you might have seen, i might have many 65mm props and some 55mm props. i also have two pairs of 45mm 3 blade props, which i like to try.


the 45mm 3 blade props are crappie af!
the 65mm props are not tighten enough
the last ones, the 55mm props are now the way to go (nope, not enough thrust!)
UPDATE I: I had this idea to grind down the props to get it closer to the motor bell (second picture). This seems to work out! And i needed to get rid of those tubes, which saved a small amount of weight.

UPDATE II: ordered some HQ 65mm props and will order some higher kV motors, eventually 10.000kV maybe 1104?

UPDATE III: the HQ props arrived and i put them on. as those are screw mounted, the screws are adding some weight. Also taped the motor wires down, with some eletrical tape.

UPDATE IV: had hard times finding this little miniKwad (microKwad?) in the field, so i've added a beeper or buzzer whatever you call it.

UPDATE: V: uploaded some more pictures of the changes I've made, or the microKwad is gone thru. one of the pictures shows the microKwad on the scale with the LDARC 65mm propeller (53,14g), and another shows how i grind the propeller down to fit them on the motor shaft. but the one of the motor shafts broke, so this hole work was done for nothing...maybe for the LDARC Q100!?

UPDATE VI: now i have those new props, and on the very first indoor test-hover i'm blown away by this performance! You know, i only have 4x 2s 450mAh (crazepony) LiPos and those aren't the best (not as worst as the ones testet by oscar liang) but i can lift and hover on lower throttle. but those props are a bit heavier, as you might see on the new cover picture. the punch is also there and i will (hopefully) fly this weekend (26-27/10/2019) on my regular small field. -Berlins are welcome to meet-

UPDATE VII: i have now changed the motors to some AMAX inno 1106 4300kV. I hope to get some nice flights with more control. the sphobby/mitoot motors seemed to struggle with the emax props.

UPDATE VIII: changed the camera to foxeer razer nano.

UPDATE IX: changed the cam again, now it's the caddx ant nano.

PS: i think oscar liang was right with those crazepony lipos.

here is some flight footage::

Hi and thanks for pictures. I would like to cut rear and front side of the frame and put camera on top. than it is just about space between props. thats why Im interested about dimensions

these props are the emax avan scimitar with 2.5", if you add another 1.25cm to the props, the props will collide. you probably want to try the iflight turbobee 136rs.

You was right, but with a litle help of 3D prited motor adapters I got 2.5" @ 3" done :)

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..
