"Hi all, this thread is very interesting for me, as it's my next plan of attack after finishing my Hexacopter. I work in construction for a large global company, and I work in engineering and land surveying. I am thinking of using the ritewing zephyr…"

"I have the same issue, the main front screen takes ages to fully load when switching back from another menu screen, I have an ATI mobility radeon 9700, it's old I know and don't think any new drivers have come out for it in a long time, but until a…"

"Hi Jason, had another test with 42 today, I upped the P in NAV WP up to  as you suggested in my other thread, but it was moving around even worse, even though there was very little wind today, I believe the expression is "toilet bowling", nothing…"

Lee Williams replied to Jason Short's discussion Arducopter 2.0.42
"Hi all, tried my first test flight today with 2.0.42, stabilize was good as usual, although it did need trimming and for the first time loiter wasn't a scary experience, I was comfortable to leave it in loiter mode without having to jump for my…"

Lee Williams replied to Jason Short's discussion Arducopter 2.0.42
"OK, I have uploaded 2.0.42 but it's too windy to test, when I open mission planner and look at the PID's none of them have changed from the settings I put in 2.0.40, how do I know if the new firmware has uploaded correctly with Arduino, is there any…"

"Wow, haven't had chance to try 2.0.41 yet, what would you recommend Jason, try 2.0.41 first, or just update again to 2.0.42, hope loiter will be good."

"How do I get 2.0.41, the mission planner only gets 2.0.40"

Hi all, installed 2.0.40 yesterday and re done all of my radio and esc calibration, I had high hopes for loiter mode having heard other peoples good reports, however it was dissapointing to find that it was the same old same old, with altitude…

Lee Williams commented on Jason Short's blog post Arducopter Alt hold
"Hi Jason, great programme, alt hold is the major issue I am struggling with, am I to take it that with alt hold there should be no I value, what values make this model most stable, is it possible to make the flas model perfectly stable, if so, what…"

Lee Williams replied to Franco Marinelli's discussion Tuning PID loop
"Hi Franco, I'm struggling with the same thing, can't get my alt hold to work properly at all, what would be good is a guide for what to alter given certain reactions, and what you would expect to change if your multi is bigger/ heavier, hopefully…"

Lee Williams replied to Rob. S's discussion Hooking up multiple batties
"If its any help we are running 3x 3s 4000mah batteries feeding into a common power ring, only issue we have is battery voltage on telemetry reading wrong, but don't know if it's because we have multiple batteries"

Lee Williams replied to Lee Williams's discussion Ballpark PID values for loiter mode
"Done some more flight testing today, with some different PID values for Alt Hold, the values are
P=0.35
I=0.01
D=0.30
Imax=20
the same issue occured with it surging up and down preety much as soon as loiter was engaged, any suggestions what to try,…"

Hi all, we are running the latest mission planner, stabilize mode is great and very stable, however when we switch to loiter mode it gets very erratic, swings back and forth about 10m and rises and falls with violent throttle changes. It's a…

Lee Williams replied to Lee Williams's discussion Newbie Hexacopter Advice
"OK, quick update and hopefully some advise. We have finished making the frame now and are installing the soldering up the megapilot board, we have GPS and Magnetometer to go on, we ultimately want the best stability we can get, so it will hold a…"
