Hello  it's since a while that i'm thinking to build a new drone, natural idea is been a 5" quad, I was a bit undecided if 4 or 6s expecially with the idea to fly also using a full size gopro for example without many issues of handling and voltage sag where you feel a lot the wheight. but exploring the TBS website i have find as frame the 6" version of this : https://www.team-blacksheep.com/products/product:4996 so I thought it might be nice to build a 6 inch. Fc there is no difference between 5-6" quad, but what esc is required for a drone like that ? EMAX ECO II are engines i would like to try and i saw are available on TBS website, there is also the version for 6" drone, what would be ? so what would be harder find and more expensive are: esc;props ...of course i have to use a 6s battery and maybe in different mAh size if compared to a 6s battery for freestyle drone where uscually you use 1300mah. ![[-]](https://intofpv.com/images/collapse.png) • Posts: 1,364 Threads: 118 Likes Received: 1,411 in 728 posts Likes Given: 1,069 Joined: Jun 2019 Reputation: 41 I would go with motors that have a taller stator like 2207.5 or 2208 if you can find them. I have found 2306 too work but probably a bit small, especially for freestyle that needs a quick response from the motors.

OK for cruising.
A higher stator will prolly help with torque hence why I suggest 2207 or 2208 if you can find them. Also bigger motors change the mounting size on the base of the motor. • Posts: 6,092 Threads: 172 Likes Received: 2,283 in 1,830 posts Likes Given: 4,721 Joined: Feb 2019 Reputation: 100 (01-Sep-2022, 01:35 AM)ph2t Wrote: I just found the 2306 ( I am using AXIS 2306 motors on my 6" badger) a little underpowered for freestyle.

900g with battery, uaw means the whole build with battery - ready to take off.
a 5ich freestyler with gopro can climb an uaw of 900g, on longer more heavy 6inch rotor blades, it needs a bit more torq, a 2306 can suffer in performance and effiency at 900g uaw. • Posts: 1,490 Threads: 92 Likes Received: 574 in 468 posts Likes Given: 0 Joined: Nov 2020 Reputation: 27 6".. it depends.
Take a light 330g 2207 5". Longer arms only add 20g. 1100-1300mah 6S 200g. 6" biblades. 550g auw. It will fly great.
But if you put those 2207 on bulky heavy 6" frame, add full goPro, and 6" triblades.. motors will struggle and lag. Prop is too much load. Too much weight. You will need 2507 motor. • |
