"Overlapping props is not a new idea, but in fact it does not do what people think it will do. We also tried it about a year ago (trying to increase lifting power while retain same small span). We did not get the thrust we expected.
"I could see very active discussion between developers, and it may seem like great FC (I mean Pixracer), but when I try to get one - no response within a month after payment. When I just ask politely when I may expect this FC to be delivered, I got: …"
"Relationships between PID settings - Vibration - INS_ACCEL_FILTER settings?
Can anyone explain these relationships? I found on my FW-450 with Pixhawk (3.3.2 fw) / RCTimer MT2610 920kv, BLHeli 30A, 1045 prop at default I_ACC_FLtr = 20 and using 3DR…"
"Is it possible to incorporate temperature calibration similar to the one that implemented in OpenPilot Revo? It seems that OpenPilot is essentially dead now, but they had lots of good ideas, which may improve APM, thermal calibration is one of them."
"I may be in a wrong thread, but since I am using Pixhawk with 3.3.1 firmware I think my question is relevant.
My setup is shown in attached pic. It is modified Flamewheel clone with RCTimer 2610-920 kv motors, Platinum 30A ESC's. I made it for night…"
"Are you sure that your Rate Pitch D: 100 ? this is about ten thousand times its maximum value, if it is copter should oscillate wildly. It is better to have pitch and roll rate values linked (same). Start with P=0.08; I=0.8 and D=0.003
"I may disagree with Brat last answer. Battery power release is not linear with voltage drop (highly dependent on the electrode surface and quality of quasi-polymeric electrolyte) also the higher the copter weight (due to heavy battery) the more load…"
