"Hi David and thanks for the reply. In my opinion you are absolutely right. Last week I quickly re-soldered the motor connections and tested them. I then spent a couple of days static testing the setup. During that time I test-changed most parameters…"
"Hi Hi Tom - your rescue boat looks ideal - small, strong and maneuverable. Thanks for sharing. I'm lucky - several club members rotate to operate a rescue service on a non-official rota. Pics below. Many thanks."
"Sorry Grant, Tom and team - I've let you down.
Yesterday my shame circuits went into overload when I lost all motive power and had to request help from the rescue boat. On retrieval, I discovered my soldering skills leave much to be desired. Motor…"
"Understood Thomas - thankyou and makes perfect sense.
To be honest, in Manual mode while sailing a straight course across the pond my boat hardly rolls at all (unless she hits wash from another boat). A lack of upperworks, relatively light weight…"
"Hi David - It goes backwards very nicely as long as you're not too concerned about the direction of travel :)
I previously built a tug with twin Korts and that boat steered backwards better than anything I've seen. But on this one, its a single Kort…"
"Hi Tom and yes - Kort Nozzle around the prop is rotated by a servo to provide steering (a bit like a very slow speed jet ski).. I didn't want to confuse the thread by referring to it directly.
Thanks for info on your Villain. I've Googled the base…"
"You're a hero Grant - thankyou. I really appreciate the effort you've gone to and will certainly get back to you after the next outing (which will be on Sunday). Will try adjusting the TConst first as suggested.
Yesterday I downloaded all …"
"Hi there,
I guess in common with a lot of folks, I get liability insurance as part of my Club subscriptions. I did raise this point with the Club committee who collectively arrange the insurance. In their opinion exactly the opposite applies - their…"
"Thanks for clarifying the accel calibration Thomas.
Also for the STEER2SRV_MINISPD and STEER2SRV_P suggestions which I appreciate.
For the sake of completeness I've attached the Tlog file as requested. Grant has the corresponding dataflash log.…"
"Yep it's a big log file.
I don't know how you'll use it, but if it helps, a representative part of the mission, which exhibits the behavior starts at 10:45:19 and ends at 10:48:11.Don't think it will help in any way but (just in case) boat pics…"
"Thanks Tom.
Used Filezilla. Filename is 2015-05-31 10-28-25.log. The unzipped file may be bad - had a couple of timeouts, but the zipped file looks to have come through clean. Am now disconnected and out of Filezilla.
Very many thanks for your help.…"
"Hi Grant. Sorry for the delay in response.
I've downloaded the dataflash.log for the single mission in question but the file size on the PC is 112MB. When zipped or rar'd the size is 25MB. I don't think I can attach files greater than 7MB in size in…"
"Hi Thomas and thanks for the info.
Yes - 3DR Ublox GPS which is mounted on the 3DR pedestal for sat visibility and noise reduction.
I did level and calibrate the compass. In Mandatory Hardware -> Compass it shows Manual - Rotation_None. Although I…"
"Thanks David - Please don't interpret my response as ingratitude - I really appreciate your help and entirely agree about the fluid environment aspects - with dozens of factors. Thank you for sharing hard earned knowledge and I'm really grateful for…"
