Summer Gecko 🦎

This quad hits the sweet spot for me. I don't think I can build a 3" drone that I will enjoy flying more than this one. I will keep trying but it will be tough.
Since the first Gecko has endured more than 3 months of almost every day flying I thought it's time to build another but still with the best (IMHO) components.
By far, the Gecko is the strongest 3" frame I have ever flown and it flies so well. The new version has a tiny TBS Unify that at 400mW delivers better video than AKK FX3 at max power. Funny how these things work. The Ratel camera seems to be almost as good as the Micro Eagle but without the notorious white flash. Except it came totally being out-of-focus

The biggest problem is availability of 3044 props. Don't you guys find it ridiculous that no one can make an aggressive 3" t-mount prop?!? Something like 3052 because this drone is too boring with available 2.4-3 pitch props! I've talked to RDQ but they need to see more interest before they consider investing into a prop.

Breading the motor wires helps how?

Hope that braided wires are a bit longer when unbraided that could help when reusing motors with a bigger frame. Not a significant reason. For this build I have reused motors from a 3" massive droner and had to use racewires for the rear motors, the wires were too short. Mostly wanted to try racewires. I feel like too much trouble for 3" quads, may splice the wires instead.

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..

This is the 4th installment to my popular "Wizard Killer" series, and is based on the popular Wizard X220HV 6S. As usual, the goal was to build a substantially better quad, yet come in below the retail price of the BNF kit. Here are some of the improvements: Higher quality EMAX ECO 2306 1700kv motors Foxeer's top-of-the-line Falkor mini camera Eachine 25mw-1000mw Leaf VTX with microphone Tools This..
