I have been wanting to build a 1s brushless tiny whoop for awhile. I decided to try the Rakonheli Delrin and Carbon 66mm frame, it looked like good quality. One of the canopy posts blockes the USB port to the flight controller, which is a pain, but can be worked around. I tried using a BETAFPV Micro DSMX Receiver at first but could not get it to work with the flight controller. Never figured out why, but a Spektrum DSMX Quad Race Receiver worked without a hitch. Go figure! I had one of the brushless motors fail on the third flight. The quad dropped right out the sky like I lost radio signal and I found the motor dead. Turns out the crash broke a motor connection at the ESC. Still not sure why it dropped out of the sky. It was 10 feet from me and I was flying line of sight. I am getting 3:30 to 4:00 minutes of flight time on BETAFPV HV 1s 260mah batteries. Current weight without battery is 27 grams. Kinda heavy compared to a regular brushed Tiny Whoop. I really was not as worried about weight as just trying to get the thing built and working. So far, after a dozen flights, I am happy with the build. Still need to tune and get the feel of the drone. First outside FPV flight below.

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..
