Ultralight 3 Inch (75g)

There have already been a few 3 inch adaptations of the Toothpick concept and the Sanchez frame is my take on it. Super light 3" builds like these just got much nicer since we got whoop style all in in one (AIO) boards like the GEPRC with an amazing 12A 4S rating. Those boards make it possible to use bigger 1404 and 1304 motors that easily spin three inch props on a simple Toothpick like build.
The Frame focussed on low weight and with 7.5g it is hardly heavier than a regular toothpick frame. There are thre "no compromise" versions that fit either 16x16, 20x20 or AIO boards plus a fourth version that has all three options but is a bit heavier.
I also tested this build with a Caddx Turtle V2. I'll link a youtube video blow where I go into details on that.
All files nessecary to get the frame CNC cut are availabe for free on Thingiverse

How do you have the vtx secured under the canopy? Does it attach somewhere or are you using double sided tape or just letting it sit htere?

wrapping it in a bit of electrical tape and just stuffing it in the canopy with the RX works perfectly fine. Its all so thight and tiny that it doesnt move around.

Sweet, gonna use a gtx nano in my since im cheap but its nearly the same size so good to know. I emailed that cnc company in the states about the cost of cutting a few frames. Ill let you know what the figure is when I hear back in case you wanna share with others.

Hmm bangood description of these motors says that it eat up to 14A in 6000kv version. And you used 6000kv motors according to photos. But your esc's are only 12A. Didn't understand this moment.

I meant 14A on 11.1V with 3045 props and on 6000kv version

14A is probably measured in a static thrust test. Real amp draw is always at least 30% lower, especually on a light quad. they pull 8.5 amps max with 3035 3 blade props when flying

Man, this thing is sick. Perfect application of the class I think! This is what 3" quads are supposed to be

Simply the best build I've seen in a while. It's the anti-cinewhoop.

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..
