wild flower 3s 1304 geprc 12a
By matthew saigon on May 27, 2019
80g dry, a bit faster and more torque than 1105 motors
this build is pretty usual, but if you have question about this build, just leave a comment.
batteries: 3s 650mah
and the pigtail of your build should be 16awg. don't use 18awg wires for pigtail.
pid is flyable, not great.

5/28/19: the video looks bad, but i don't know how to make youtube videos. you can hardly see anything. i'll try to put capacitor on it to smooth out videos but that'll take a few days.
i crashed but it's still ok :)
3s 550mah
5/28/19: 3s 650mah. video looks really bad. don't watch it :)
5/29/19: i think i know what the problem is. i think it's the hglrc nano vtx. 25mw feels like 15mw and 50mw feels like 25mw :(

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

awwww mannnnnn you beat me to the 3" whoop build ahhaha. This is lit!!
whats your flight times?
with 3s 650mah, it should be about 4 minutes, but if you do many power loops then it's about 3 minutes. at this weight you can use 3s 850mah. but remember to use 16awg wires for pigtail and battery power lead. i saw your video and i think this might not be good for where you're flying. this is for park only, flying over grass, hitting branches and fall on grass. it's not meant to fly around brick walls and metal or over asphalts and concrete :) plus yours is 4s 1306, i don't know if you want to go down to something less powerful. 3s 1304 are not as powerful as 4s 1306. anyway, this setup can take more weight if you like to add HD to it. it should be about 90g. and it's good with lighter props like avan 3", 3025, hq3x3x2.
the video still looks bad but i at least can see where i'm going. you can get really long flight times with this one. 3s 550 for light weight, 3s 650mah is my favorite, 850mah you can feel the weight but not too bad and you can have longer flight times. if you just cruise around like in your video you could have a really long flight times.
