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.

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..
