Hi all, so I'm about half way through my second FT SPEAR build and I was wondering if anyone had any suggestions for a long range power setup. In my last build I had a sunnysky 2216 1250kv motor spinning a 9x4.5 inch prop powered by a 3200mah 4s. This setup did get me around 20 minutes of flight time which could get me a 13-14km round trip with the vector. I was wondering if 3s and a larger prop /lower kV motor would be more efficient. Any suggestions would be great!
