It was time to build a 3" and I wanted to put my Split Mini in it. I wanted range and fly time. Almost got a Switchback, but I'm trying to build every Falcon Multirotors frame. All I needed to adapt it was a couple longer screws for the camera and a couple bits of tubing. As of right now I've gone as far as 3km and as long as 9 minutes. I'm very happy with this frame, motors, props, pack, rx, fc, really the whole build. Everything came together to give me a perfect micro "long" ranger,backyard derper, and permanent home for my Split Mini :) AUW w/ 850 3s = 202g, w/ 1300 3s = 241g, Dry = 121g

What a nice build! Isn't that Slim+ with two antennas a pain in the butt? I just finished a very similar build.

Are you using Taranis X7 with R9M? I am stuck on 10mW power, the radio skips over the power level in the model setup. I can't change it. I am pretty sure I have the latest firmware. Thanks!

Woah. that's a weird bug! did you make sure to update the module firmware and opentx to the latest versions? Maybe hit up the R9 user group on fb. Haven't heard of this one before.
The two antennas weren't too bad. Just had to get a little creative. Worth it for strong signal at just about any orientation.

Upgrade to OpenTX 2.2RC4 solved the issue. Thanks!

Btw, I am pleasantly surprised by the performance of R9 mini and it has just one antenna! That's plenty given the 5.8 video range.

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..
