Trying to build brushless whoop for winter because why not.
Motors will be 12000kv version. Already has rx. No idea about batteries. Added in some "training" props. Also probably will need either charger (USB one?) or buy/make para charging board/cable.
Update1: BG no longer ship batteries to Czech so HK nanotechs are like only option. Found some charger on bg, see if it works or not, can remake it into para board if anything fails.
Update2: Switched to 12000kv for less power. Everything is ordered (apart from batteries which will come fast anyway). 4 weeks of waiting starting now (25.9.2017)
Build done
Update3: Pictures shows progress of building. First was desoldering esc and adding wires from fc and for battery. Then getting the frame together with camera standoffs. After that was screwing motors in place and soldering (copper!) wires to esc. After that soldered rx and aio in place and adding props.
Batteries are still somewhere on post office so can't test it (yet). Flashed with bf 3.2.1 waiting to rock around.
Thing flies
Update4: Finally resolved all issues and made it to fly. 33 grams of pure awesomeness. You can see the result here:

Seems that Flight controller is no longer in stock. Anyone else sell it?
Seems that they are selling it only as a combo together with 6A ESCs. https://www.banggood.com/Teeny1S-F4-Flight-Controller-Built-in-Betaflight-OSD-Teeny1S-4-In-1-6A-BLHeli_S-ESC-for-RC-FPV-Racing-Drone-p-1176420.html
Oh well...
Where did you get those esc/fc mounts? Do they come with the RKH kit? I just ordered mine and want to have everything I need to assemble when it comes, if you have a list of hardware required it would be super helpful, this will be my first build.
How do you think 10000KV motors would work on a build like this?
What motors would you use if you were going for 2s?
weight to thrust should be around 2:1 i guess, maybe 1,5:1 (it weights 33grams, one motor should make 15g thrust, 60g in total with 56mmx1mm 2 blade)
as for 10000kv on 2s feeling like 20000kv on 1s, with double the cells, you are getting aproximately double the kv, just sag should be more noticeable on 1s

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..

I see you used the rakon frame but did you buy it from Rakon? They seem to have 2 different frames one says it's for 703 and one says it's for 703 and 603. The link on yours is to rakons site but the sell the 703 at helination. I'm trying to figure out the difference because rakons shipping is crazy slow. Thanks.
Yes. I actually bought it from them, took like 3 weeks to get to me. And I dont think the motors have different holes so you should be fine with both version.
Awesome thx!
So in your opinion are 703 motors better for this than 603? And do the 703s perform well on the lipo you used?
it was based on the info and stuff i could get almost a year ago, things definitely changed now
as to lipo performance, i only had qx90 (the original version) to compare it and they were kinda similar, just this one had far shorter flight times (230 vs 500mah). Probably wont survive any wind but flew it even in school and it did great
