"The 99.9999999% are really hard to believe - especially when considering the X8 layout.
I have learned from several crashes that the X8 layout does not provide a lot of an reliability advantage over the usual quad, if any. One example: one of the…"
"@Tom: I do not aggree - the single point of is very easy to avoid: simply move the switching logic into the ESCs. Some problems might persist (which FC is right?), but at least you have 6..8 redundant switches and a redundant wiring.
BTW, given that…"
"As far as I understand the device, the AP Manager itself is can be considered as a single point of failure. It adds another PCB, plus lots of additional cables, all of them can fail. So where is the improvement in redundancy or reliability?"
"I have flown the v2 module with ArduCopter (master) an can confirm that the new module is working nicely and performs very well. It is almost plug-and-play with APM: after setting the params BRD_CAN_ENABLE to 2 and GPS_TYPE to 9, it is auto-detected…"
"When losing one motor on the X8, shouldn't it be enough to throttle down exactly one opposite motor? That means we have lost 2/8 (25%) of power, not 50%. But probably we need the ESC feedback here to find out what motor has failed.
"After some years of experience with ArduCopter, I would characterize the reliability aspect of ArduCopter as good, while the functionality aspect is outstanding (IMHO).
When looking at my past crashes caused by ArduPilot (about 10 or so in about…"
amazing work! Have you ever tried to commit your work to the upstream OpenTX project? That way your changes would be maintained by the upstream project and your changes would "stay alive" in newer revisions of OpenTX without having to adjust…"
"I use cells without tabs and solder apropiate copper wire directly onto the poles. The 18650 cells are very easy to solder as log as you do not bring to much heat into the cell. To prevent that, I use the following technique:
1. use a large…"
unfortunately these batteries are not really suitable as drop-in replacement for existing copters. In your case, I guess you will heavily overload these cells, as 25mins are more than the allowed absolute max of 2C. Keep in mind: the…"
inspired by your post I just browsed some old logs. I found two logs of flights at approximately 1C. All measurements were taken with calibrated SM Unilog current/voltage sensors. Both flights were in Februrary at 14°C, and 16°C…"
"I use these batteries with good success in my FPV quad (5s3p, RCTimer 5010, 16x5.5 props). Flight time is about 40 min (down to 3.0V, plus some reserve), maximum current at full throttle is about 4C/35A. During normal flying the power goes rarely…"
"I usally just exchange two leads on each ESC. The props run backwards in this case, pushing the copter down like turning the props. But there is a major catch: it only works with the current sensor: the throttle to current response of a prop running…"
