thanks again!
So I have been researching a bit and it seems I can´t find anyone who has the MN3510 or the MN3508 700kv in stock, so i´m considering other navigator engines. Have played a bit with ecalc and got some approx values and hover times.
The weight im basing it on is approx 2.532kg (500g for gimbal and gopro3) including a 4S 6000mAh lipo pluss the weight of the different engines.
MN3508-20 580kv - hovertime w/12x4 prp 11.33min(27.01A) - Max thrust w/12x3.8 prp 8160g(84.6A)
MN3508-16 700kv - hovertime w/12x4 prp 11.05min(27.77A) - Max thrust w/12x3.8 prp 10080g(135A)
MN3510-13 700kv - hovertime w/12x4 prp 10.65min(28.74A)- Max thrust w/12x3.8 prp 10800g(142.8A)
MN4010-9 580kv - hovertime w/15x5 prp 9.48min (32.29A) - Max thrust w/15x5 prp 12060g(124.2A)
MN4012-9 480kv - hovertime w/15x5 prp 9.25min (33.06A) - Max thrust w/15x5 prp 10320g(90A)
If i am going to add some more weight (lets say 2kg for bigger gimbal and GH3) and 2x 6000mAh lipos, things change a bit:
MN3508-20 580kv - hovertime w/12x4 prp 10.43min(58.67A)
MN3508-16 700kv - hovertime w/12x4 prp 10.52min (58.15A)
MN3510-13 700kv - hovertime w/12x4 prp 10.38min(58.95A)
MN4010-9 580kv - hovertime w/15x5 prp 10.89min(56.17A)
MN4012-9 480kv - hovertime w/15x5 prp 10.6min
So the best suited engine in this scenario seems to be the MN4010-9 580kv. But will the 15 inches props fit on the 34cm booms in a hex config?
