"The default imax is too low for this kind of fram with really "long" (I donno how to phrase it) center of gravity, one of the pitch sides with camera at the edge (sometime heavy gopro) on the other edge the battery, the imax says how much can be…"

"So did another autotune on a much less windy day (still but windy but no gusts), got very different results: 0.003 D for roll and 0.00130 for pitch, pitch P i got 0.2!!!
I think autotune is set to give a calm vehicle, but I want to get a sharp and…"

"Tried 3.2rc5 (now already in Mission Planner beta), was also widy, lpf on 42hz, managed to complete autotune hooray :)
End result seems close to what I had except the very low D on the roll 0.0020 (was 0.0060) on the pitch its: 0.0120 (was 0.0150),…"

Already had 6 tuning sessions of complete 8 batteries. looking for number 9 with 3.2-rc5, when is that due? :)
Last tuning i actually did find out my PIDs were too high but not the place always looked but the stab P…"

"I believe now that the control inversion happened more than twice, it was just twice that I was LOS and notice what is actually happening, the other times I was FPVing and though I was loosing control because of the flips and orientation so I…"

"I tried Acro on a Mini, Putting the acro_rp_rate on the max 10 still doesn't flip fast enough, I added expo to my RC to be able to controll it.
also after a few flips my pitch was reversed suddenly and I almost crashed, putting back to stabilized…"

"On the opposite, these small frames are very rugged and with small props there are no vibrations.
Most Arducopter buils are around much bigger and more vibrating frames, thats why the default LPF is 20hz, my guess is that it doesn't fit a mini, I…"

"An old post, but I just built a Mini based on Mini APM, Kim250pro frame sunnysky 2300kv and 6" props.
It was very stable on high PID but oscillated on throttle and wobbly on low PIDs but ok on throttle.

What really really helped is: I raised the…"

Shay Sevet commented on Jethro Hazelhurst's blog post An interesting solution to flyaways...
"Any decent radio system has hopping channels and I'm pretty sure some sort of ID is exchanged between the TX and RX (binding), I'm not a radio expert but would expect that at best the interference could cause a cut in the TX-RX link which would…"

Shay Sevet commented on jlcortex's blog post Probably the smallest arducopter frame?
"Watch out as the mobius interfere with GPS until total blockage, I had a GPS block with it whe nit was 5cm away from the GPS, there's a thread about it over at RCGROUPS "

Shay Sevet commented on Andreas's blog post Neo 6 Gps Mount (Crius PCB) - 3D printable .stl file
"I have same setup, great GPS reception putting the GPS there: uBlox not MTK, I don't see why you need the GPS mount, just 2 zip ties, one through the holes and one on the pcb, every gram counts....."
