Rebuilt a 2.8-inch quad to 3 inches. 2.8inch gave 170km/h!!
T-Motor 1408 motors allow for it and deliver a massive 726 grams of thrust each—that's 2.9 kg in total! This might just be the most powerful setup for the 250g category. Dry weight is 175g, and with a 530mAh 6S GNB battery, it comes to 249g. That gives a thrust-to-weight ratio of 11.6!
Will check it out when there is no rain.
If needed, I could trim it down just a bit more, but it's unlikely to save more than 5-10 grams.
I'm using the Flywoo GN745 AIO, which is perhaps the only AIO on the market with connectors for VTX, GPS, receiver, and USB-C.
Here is the best weight to time GPS I found. Geprc nano.
I've designed a family of frames and am now slowly building various setups on them. The 4-inch mini long-range turned out pretty well. The idea is to make the top plates easily swappable, so all the frame "bodies" are identical. I can't buy a dozen DJI o4 pro (
I also like the 4.5-inch 1804 running on 4S/5S, but right now I'm testing this build with 5-inch props (4S)—I had to reverse two motors to make them fit within the frame. The motors feel a bit underpowered, though proper tuning might be all it needs.
