I'm building something similar to this right now, but with the hq4025s for efficiency and slightly larger motors. The goal is ~230g with a 3s 18650 pack. What kind of flight time have you got on the 3s pack? I'm curious how it flies like that.
I'm quite happy with how it's flying on 2s so never try 3s on the field, just a hover test indoor, but the 3 cells is blocking too much air blow in that configuration, will try that later on dead cat version.
If you can get 230g with 4 inch 3 cells, then it's definetly much better, just a quite challenge unless you remove the HD cam and/or GPS.
That seems like a high kv for 3s. Did you go that route to help offset running the voltage lower (guessing around 3v vs 3.5v for end voltage) with the 18650s? Also have you seen anyone using any cells smaller than this? I know I've seen smaller versions of 18650s but with the same chemistry. Unique buuld, great job.
I see people running these motor at 3s before so I gues the real kv may be a bit off, the real benefit of 3s is easy for ESC & high power vtx selection, most required >6V input while 2s will go down to 5V (2.5V/cell). There are many smaller cell format (18500, 14500...) but you may not gain much benefit with low mah cell because of heavy aluminium cell, in the case you want higher voltage, may want to check low c lipo battery for goggle or rc car/boat.
Very cool build! So, how are you liking 18650's for flight packs? I've read some good things, but have yet to try them myself.
It's best for long range crusing build without punch out or deep dive, flight time is 10 - 20 mins. Their low discharge current ask you to plan your build more carefully, they could go up to 30A at maximum but will seriuosly harm your flight time because of voltage sag & reduced capacity, best to keep under 10A. I use bi-blade & 3s 450 if I want some free style.
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..

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..

very nice build, I'm curious to know how you've installed that antenna to the aio fc, I got a similar crazybee aio fc with that single linear antenna and wanted to upgrade to a pagoda lollipop like you did, can you tell more about it?
This is the old FC without onboard VTX, there is a TBS unify pro32 inside the canopy.
