Swapped the supplied standoffs with RS-90 2mm nylon hardware and it looks much better. Had to trim the upper deck for the camera to fit, shouldn't be a problem when crashing I hope! Would love to fly it, but I seem to have fried a motor - which is disappointing! Waiting for a replacement from the UK which should hopefully be here by the end of the week... 52g without a battery. ![[Image: P4040216.jpg]](http://i1234.photobucket.com/albums/ff416/jimbo_wa/BoBo-95/P4040216.jpg) ![[Image: P4040217.jpg]](http://i1234.photobucket.com/albums/ff416/jimbo_wa/BoBo-95/P4040217.jpg) ![[Image: P4040218.jpg]](http://i1234.photobucket.com/albums/ff416/jimbo_wa/BoBo-95/P4040218.jpg) ![[Image: P4040224.jpg]](http://i1234.photobucket.com/albums/ff416/jimbo_wa/BoBo-95/P4040224.jpg) Posts: 91 Threads: 10 Likes Received: 84 in 45 posts Likes Given: 105 Joined: Aug 2016 Reputation: 2 06-Apr-2017, 02:55 PM (This post was last modified: 06-Apr-2017, 02:59 PM by jimbo_wa.) Well, I haven't fried a motor as the replacement (stupidly bought a 1105 and not a 1105B) doesn't work either... All 4 ESC's will flash Blheli_S fine and no issues are found when changing parameters either, but ESC/motor 1 will not spin. If I swap ESC/motor1 onto pad 3 on the FC, everything springs to life - so it's not dead a ESC/FC, but looks like a wire issue? Resoldered everything and putting ESC/motor 3 onto pad 1 on the FC result in ESC/motor 3 not moving. This is the FC I have and there are pads 5 &6 on the underside - can I remap in Betaflight to get this working? ![[-]](https://intofpv.com/images/collapse.png) • Posts: 91 Threads: 10 Likes Received: 84 in 45 posts Likes Given: 105 Joined: Aug 2016 Reputation: 2 • Posts: 62 Threads: 12 Likes Received: 16 in 11 posts Likes Given: 12 Joined: Apr 2016 Reputation: 1 Did you ever get it flying? • Posts: 227 Threads: 35 Likes Received: 202 in 116 posts Likes Given: 278 Joined: Mar 2017 Reputation: 5 Nicely done, man! - I actually have one of those lying around too, you just motivated me to give it another go somewhere in the close future ;-) Those micros are perfect for thrashing around subterranean parking lots, *heheheee.. Because of its weight specs, you're sure to be on the legal side.
The view of the FC gave me some spontaneous shudders, though - I'm still recovering from some sleepless nights spent over a family member of your FC, an Airbot F4 clone with similarly deceiving terminology in the name. I was using a Frsky XM+ Rx, but it seemed that - as Unseen rightly set me upon - the Kingkong 90GT FC could not handle the number of channels..
The Airbot clones, I've warned about them in another post already, showed tendencies of spontaneous decomposition. Sort of IC-seizures, and besides that I don't know up to which point the "Chinese D-Shot" can be believed. In my case there was no way to make more than 2 motors work on D-Shot, despite it being in the specs. Got it to run on Multishot pretty decently, but the FCs, as said, tended to spontaneously "format" themselves. Guess that's some unresolved interference-issue, but considering the low price, wasting time on it seems erratic. I've learned my lesson and I'm sticking to original dev-stuff from now on, unluckily my Rotorgeeks-FCs are still stuck at customs. They must be pretty awesome, if even custom officials cannot separate from them..
I ended up "pimping" my 90GT up to 4s capability & corresponding "real-size" components, it was flying bloody fast with those, but frying motors over it. It had been worth the fun, however, and an appropriate revenge for having me going haywire over pin-outs and spontaneous resets..
Happy flying and stable setups to you!!

Looking forward to some footage Cheers - I really should know better. The FC is now no longer recognised in Windows (no USB device detected or DFU) and a couple of small components on the underside get really hot when powered via USB, so currently waiting on a replacement. Looks like this will take a bit longer to get into the air...  • Posts: 2,410 Threads: 136 Likes Received: 1,790 in 1,052 posts Likes Given: 3,302 Joined: Jan 2017 Reputation: 50 Bummer man.

This thing is never going to fly... New FC has arrived from Banggood, rewired everything and I still have a dead motor on 1... Swapped out the speed controller for a new one and still a dead motor on 1... Realised that my spare RotorX 1105 motor is a 4000kv and not the 1105B 6500kv that I need - arse. At least it looks nice! ![[Image: P5160470.jpg]](http://i1234.photobucket.com/albums/ff416/jimbo_wa/BoBo-95/P5160470.jpg) ![[Image: P5160469.jpg]](http://i1234.photobucket.com/albums/ff416/jimbo_wa/BoBo-95/P5160469.jpg) ![[Image: P5160471.jpg]](http://i1234.photobucket.com/albums/ff416/jimbo_wa/BoBo-95/P5160471.jpg) Does anyone want to swap a new 4000 for a 6500?  • Posts: 91 Threads: 10 Likes Received: 84 in 45 posts Likes Given: 105 Joined: Aug 2016 Reputation: 2 Now soldered in a new set of 1103 8000KV motors and another new ESC for motor 1.

If BLHeliSuite can see the ESC then it has both power and a working control connection to the flight controller. If you try to spin motor 1 in the Motors tab, does it still refuse to spin? • |
