Blue Bunny - Droner 2.5
By DaveyDrones on Oct 21, 2019
Posting my first build to share my learning experience. Im sure there are many things that can be improved, but I am pretty proud of getting my Droner up in the air with only minimal hair-pulling. Given this is my first venture into this wonderful hobby, I would love any constructive feedback avilable.
I live in a fairly tight urban area, so a full size drone was not in the cards. Using other rotorbuild aritcles and the assistance of some friends, I was able to create the parts list below. I have gotten about 2 full flights on my RDQ 3S 650mah batteries and it seems to be working well! So far no specific Pid or Rate changes, still figuring out where I can improve control.
I don't have a ton of confidence yet in the Xing nano motors, but man do they look cool!

Firmware Used:
Kakute F7 Mini - Latest as of Betaflight 4.1 (Non Legacy)
Tekka32 ESC - 32.7
R9MM - 190201 2019-02-13
R9M Lite - 190201 2019-02-13
While I dont have any experience for comparison, I would say this came together fairly easily. Any problems I encountered were software/Firmware related and were resolved after a few hours of troubleshooting.
Problems Encountered:
-
R9MM On the latest ACCESS firmware was not connecting correctly with my R9 Lite module. It would also not take a downgrade to the pre-access firmware. I had to purchase a second R9MM and load the legacy firmware. After that everything worked like a champ! I'm still not sure if this was a RX/TX binding issue, or that I was trying to use Fport.
-
Motor direction was reversed on 3 of my 4 motors. After some fighting with the Blheli Chrome app, I discovered that my ESC requires the Belhli PC suite. Once I got that connected and updated, reversing the appropriate motors was a breeze.
- Currently struggling with OSD not appearing correctly. I will update as soon as I get this working properly.
I plan on updating this build as I continue working with my droner, as well as take some more detailed photos to share.
FIXED: Had to reupload the font and move some content away from the edges of the screen. Looking good now!
Thank you to Rotorbuilds for providing the guidance I needed! I also want to thank Oscar Lian and Joshua Bardwell, as I could not have done this without their excellent documentaton and video tutorials!
Edit 11/8/19: Added new photos of improved pigtail.

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..

That's a great looking build! I do reccommend that you cover your cap leads... its possible to short across them during a crash or just working on the bench.
Thank you! appreciate the feedback! I was a little concerned about the pigtail/cap in general myself, I will definitely get those leads protected.
You're Welcome! And welcome to the hobby! I haven't tried installing the cap to the battery lead, I usually use a wafl's cap cap, seperate lead, heatshrink the whole thing, and then ziptie it to the frame (away from props).
