"most liquids react as slmost solids when sudden speed object try to force it.
try to shot a bullet on water to see it (don't do it, bullet will bounce out)
anyway when crashing g forces are so great that apm will not break only for the omogeneous pr…"

"Olivier I have some idea to share and some code too, I would like your opinion, can you please check your invitation so we can speak a little?"

Frank replied to Marshall Dias's discussion Non-Powered Glider
"Same thing here but with a powered glider, I only  have 5 minutes of full throttle and wish to setup a  glide only auto mode..any help? did you find a solution? I actually permit the autopilot to use only half the power, it do level flight at 30%. a…"

Frank commented on Bart's blog post Copter-GCS now supports MAVLink
"Hi, I use your software with my custom arduplane. I have some other data that I wish to display, I send it as mavlink in throttle, battery %, packet lost. in reality they are rc uplink and downlink rssi and video rssi. Also I have 3 voltages that I…"

Frank commented on Roberto Navoni's blog post Multipilot32F4 Project Update: board and VRIDE PRO with VR OS 0.0.1 Available for developer
"Hi Roberto, what kind of failsafe is inside it? does it have ppm like apm with same limitations?"
Dec 15, 2011
Frank replied to Mike Mac's discussion The new multi-aileron option
"Doug
Anyone who try new code need a failsafe in case of hang, at least I need that.
Also hw can freeze for external problems like bec going under  a certain voltage for a second.
The important si being aware of limitation, thing that is not pointed…"

"oliver I have a good code on plane and need planner to help it, can you consider to help?
now I have camera moving with dcm and gps to target a place, when I move the camera code returns the new lat and lon pointed.
 xplane simulation and ground tes…"

Frank replied to Ilya's discussion Autopilot and camera
"now I have camera moving with dcm and gps to target a place, I should implement opencv on the ground to send to the plane the corrections needed. to be fair xplane simulation and ground test reveals no need for such an error correction, but point at…"

Frank replied to Mike Lantz's discussion Gyro's have a mind of their own
"I had same problem.
Find the pins of the chips that are giving the wrong signal and put your solder on it for 2 sec to  resolder them, it worked for me.
you can resolder every pins on each chip too. 
apm hw is not well engineered, it bends when you…"

Frank replied to Mike Mac's discussion The new multi-aileron option
"wiki is wrong this is maye the 3rd time I say that.. you should set rc5 = 4 not 1 that is passtrough.
it has no hw failsafe, only sw. is apm reboots you lose tha 2nd aileron"

Frank commented on Jean-Louis Naudin's blog post ThermoPilot project: a Thermal Hunter Glider drone
"is the code open?
I started something like that and was developing when I crashed my plane, I too was using only gps altitude at 10hz and it was very good despite all the things people say about vario resolution.
I wish a code to start with, is your…"

Frank commented on Olivier ADLER's blog post ArduPPM 0.9.87 reports - pushing it to 1.0 release.
"another solution is that ppm chip read and creates ppm sum, both connected to rx, this is doable and will work, I've done that before with my own autpilot years ago. obviaously you should cut the ppm sum trace in the rx make it unusable in the usual…"

"I studeid the hw. ppm code can't better than this so the things I point are not a ppm code  "bug", go on with the 1.0 release.
I suggest to point up the limitation of hardware both in ppm and aux funcions wiki so nobody crash the plane thinking that…"

Frank replied to Steve Gemmell's discussion Ailerons on Channel 5 and 6
"Please note that there is no ppm passtrough on ch5. This means if you apm hangs or stop working properly whatever is connected to ch5 output will go random. your plane will have an aileron fault. I found this very dangerous especially for firsts fli…"
