I see you ended up going with the lower kv variant of the rg 1407s, how do they compare to the 3200kv? Do you think this setup has an advantage over a 4in quad?
Hi mate, rotorgeeks kindly sent me both to test (3200 and 2800kv). It was very prop dependent, on both 5030 and 5045 the 3200 were slightly faster although there was a bit of a plateau at the top end on 3200 with 5045, 5040 were the fastest props but the 3200kv at WOT were again plateauing and kicking the hell out the lipo, with dramatic voltage sags. On 3s you get a fast agile quad with good flight times with either so would probably run 3200 for that extra bit of speed, if you want the fastest though with viability for racing on 4s then 2800kv with 5040 props is the sweet spot.
The best quads I have (and I have a lot) are my kinetic aerial air-ro running F20ii, they match most of my 5 inch for speed but have the agility of micro due to the low weight. Thirs sort of 5 inch have the same agility but more speed. Hence for freestyle/acro an ultralight 4 inch with F20ii is, imho, pretty unbeatable, but this has an advantage for racing (assuming the track allows you to use the speed)
