APM 2.0 Dataflash Chip

Started this discussion. Last reply by Cadbury Dec 16, 2013. 1 Reply

I have a bent and battered 2.0, that went through some crashes. First, the Mediatek GPS got ripped off and I went with an external U-Blox. Then, to my astonishment, I found the SD-Card-like dataflash…Continue

Low-KV / large prop trouble

Started this discussion. Last reply by Nicolas Feb 25. 5 Replies

Greetings.I have a quad equipped with RcTimer 5010 360KV motors and 16 inch props, running on 4S LiPo. Nice and steady platform for FPV and amateur video, flew it all spring and summer with a chinese…Continue

Para replied to Cory Hill's discussion Pixhawk + Taranis / X8R Fail Safe Configuration
"On X8R it's the SBUS. The horizontal connector below all the vertical PWM ones. Do not connect it to the S-Port where the antennas exit the case, because that's for telemetry."
Para replied to xoltri's discussion Pixhawk causing motor sync issues.
"It's a rather convoluted setup, but it works. You have to flash the bootloader (either simonk's for use with Turnigy USBLinker or an AVRLoader to use with an Arduino) with an USBASP or equivalent, then switch to the single-wire programmer…"
Para replied to xoltri's discussion Pixhawk causing motor sync issues.
"George, xoltri. I've played with my F-30s over the weekend. Simonk, BLHeli and Wii-Esc firmware. The winner is definitely Wii-Esc with comp_pwm on. Simonk 3/6/2014 won't desync anymore, but for 0.75 Kg of thrust it will ask for 8.8…"
Para replied to Bryan Anderson's discussion Pixhawk Quadcopter Yaw
"I don't know if an autotune will help a yaw drift, as it only tunes roll an pitch, but you might try it, because when a motor accererates or decelerates, the angular (yaw) influence is immediate, while thrust (roll/pitch) is a bit delayed. You…"
Para replied to Stone1295's discussion Pixhawk + Taranis X9D + FrSky X8R
"Stone. Get the Taranis in D16 mode and bind with the X8R in either Mode 4 or Mode 5 (instructions in the X8R leaflet or pdf). Get to the mixing table and start defining CH1-4 as AETR and add a switch or mix of two swithes to CH5, a pot on CH6 and a…"
Para replied to xoltri's discussion Pixhawk causing motor sync issues.
"Then don't buy an ESC32 :) They have two calibration sequences that you do with the prop on, ramping up the motor between different rpm ranges. And if your parameters are unsuited to the motor, and it detects a desync, it screeches to a sudden…"

Para replied to Ritche M's discussion help needed: motors will spin only at 40% throttle and hover at 55%
"If you're using the Quadro ESCs, I'd advise you to buy a SiLabs ToolStick and reprogram them with BLHeli. The GUI allows you to set min/max pwm values and min_command on each ESC."

Para replied to Nolan Crook's discussion Generic Magnetometer on APM 2.6??
"Nolan, you can't differentiate between two HMCs. Just make sure SCL goes to SCL and SDA to SDA. I2C is not like a serial port where Rx goes to Tx. Then pay attention to mag orientation. Default APM orientation is chip facing up and pin1 dot on…"

Para replied to Randy's discussion AC-3.1 autotune support discussion
"Try getting Rate_D tuned first. I had some setups that needed 4x the default D to become tame enough for Rate_P adjustment."

Para replied to Randy's discussion ArduCopter-3.1 released!
"Randy, will spline wp be manageable for APM 2.x, or is it PX/Pixhawk domain ? Moreover, is my hope that spline will improve follow-me behaviour misplaced ?"

Nicolas replied to Para's discussion Low-KV / large prop trouble
"Hi, i build a quad similar to yours, (4s, 470kv, 17*5.5 prop, esc 30A), and i am quite in trouble with pid tunning. did you finally get something correct? could you share yours? thx"

Para replied to John Brown's discussion Any Success Stories with APM2.6 or Pixawk in follow-me mode from Europe? in the group ArduCopter User Group
"I flew follow-me with Droidplanner last autumn, with 3.0-rc2 iirc. My well-tuned quad was jerky at each movement start. I also was disappointed that it didn't keep the initial distance to my tablet. Whenever I stopped it came right above my…"

Para replied to Oliver Volkmann's discussion Altitude Hold Proving Dangerous
"My experience with an overpowered quad: the first param I adjusted was Rate D, and I ended up with 0.016 instead of 0.004. It was buzzing a bit with high-freq oscillation, so I lowered Rate I a bit, then started raising Rate P. Had almost 5 to 1…"

Para replied to Dustin C's discussion Trying to connect Pixhawk to my receiver?
"I've connected the SBUS port of the X8R receiver that came with my FrSky Taranis, and everything is OK. I bet that if I connect the CPPM port from the D8R-XPs that I use with my APM 2.0 and 2.5, it will also work as advertised. If you have the…"

Para replied to Jeffrey Nichols's discussion My Hex powers down and falls from the sky after 3.5 mins.
"How are you powering your APM ? The Afros only have a tiny 500 mA linear BEC."
