"Only thing is (of course) that less vibration reduces the risk of failures in electronics in general.
However unlike the IMU, where the acceleration sensors get somewhat swamped by vibration, so good damping improves behaviour, something like a thin…"

Harley Engholm replied to Randy's discussion AC 2.9.1 vs 2.8.1 GPS accuracy"Today I made my first flight with the ublox gps. I had been using the MTK and was not satisfied with the accuracy etc. It would wander around sometimes in a 30 to 40 ft radius and I could never run a battery thru without correcting the position. I…"
Harley Engholm replied to Harley Engholm's discussion GPS vibration damping"Thanks-I hadn't seen anything on it, but wanted to make sure I hadn't missed something."
Richard Boyhan replied to Harley Engholm's discussion GPS vibration damping"I not heard anything on vibration damping for GPS. I Velcro mine to the top of my stack. It's away from other electronics and has clear shot of the sky. Works spot on."

Harley Engholm replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"I could be wrong, but when you are in loiter mode the apm does all of your leveling etc to maintain position, so I would think you would see pitch and roll inputs that the apm is providing to maintain position etc."
Harley Engholm replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"I routinely have both my 3dr 900mhz plugged in at the same time I am using the usb port and so far I haven't had any problems. I know you can't use the two at the same time but I haven't seen adverse effects on the apm. As Leonard…"
Harley Engholm replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"Thanks-I will make one of these-should work well for the MTK as well."
Harley Engholm replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"I saw a post (I think it was yesterday) showing the gps mounted on a pcb plate that should help gps accuracy, but I can't find the post today-does anyone know the link?"
Harley Engholm replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released"I had used foam isolation from the beginning, but today I looked at the isolation to see if I could improve it without a major change. I had the apm sandwiched between two layers of 1/4" foam. I had 3/4" standoffs separating the…"

I have the external gps but need the software and instructions. Where…"
