Introduction:
I was pretty excited to try out some of the new HappyModel 1102 13500kv motors. I loved their 8500kv versions since they have a great weight to power ratio.
Components:
- Crazybee F3 5a AIO (UR65 board)
- Happymodel EX1102 13500kv x4
- Gemfan 3025 x4 (trimmed by 2mms - to fit this smaller frame)
- Eachine TX06 AIO camera
- Buzzer
- Sailfly X frame
Conclusion:
I had really high hopes for these motors. Till now, my favorite 1s 3" is still the Banshee2128. The LDARC 1102 12800kv motors are nothing short of extraordinary. If anything could overtake those motors, it would be these. I didn't put it on a newt frame because the last time I drilled a newt for these happy model motors turned out to be far more work than I anticipated. The reason is because the screws on these are so small and it required a lot of re-work. I figured trimming a couple of mm's on the props wouldn't yield too much of a difference in performance. I also decided to use a mobula camera mount this time just for kicks. It did require some minor "surgery" with a soldering iron so I could access the usb port on the board and also for better prop clearance along with weight savings.
The final dry weight came to 35g, which was the same as the Banshee2128. On the first battery itself, the low battery warning came with the first punchout (I was using old packs). It seemed to fly really well, but it was definitely pulling a lot more amps than the LDARC 1102s without any significant difference in performance. I thought it was just one of my worse packs and tried a couple more packs with similar results. I then tried the LDARC 1102s again with the same packs and they performed great with no voltage sags. It's really a shame, but at least I still have a great performer (Banshee2128).
