"Hey, patrick can you share the code? 
I'm interested on the result. 
Thanks

nicolas grunbaum commented on Jimmy Oliver's blog post Walabot. Has anyone seen/experimented with this?
"Looking at the api from walabot, in one example i found: 
// Walabot_SetArenaR - input parameters
double minInCm = 30;
double maxInCm = 200;
double resICm = 3;

Probably the range is around 2 meters. "

"i just charged back the packs and i got 6715 mAh so i think i need to calibrate the current sensor. "

nicolas grunbaum replied to Jacob Densmore's discussion Flyzone Calypso as platform
"I'm using a 3cell pack in the front, and 2 3cells packs (one on each wing). I just added 21 gr on the tail to equilibrate. The cells on the wing are on the cg line, so they dont induce any unbalance. 
I will make a photo tomorrow to show you what i…"

nicolas grunbaum replied to Jacob Densmore's discussion Flyzone Calypso as platform
"Today i flew the plane on a 45km path, it took 1h20 minutes to complete. The Amps draw was around 3A mean value, a total of 4500mAh used out of a 8100mAh li ion (18650PF) pack. I stoped because the plane had no power to keep flying. I believe the li…"

"I just weighted the plane. It's 1100gr AUW. Today i did a 10k flight. Flying at 10m/s airspeed the draw is about1.5A to 2.5A except for the takeioff of course."

nicolas grunbaum replied to Jacob Densmore's discussion Flyzone Calypso as platform
"As you can see, the pixhawk takes half the place on the cockpit, esc goes up front with the x8r receiver, 915 telemetry radio goes just next to the servos (i made a hole to pass the antenna). Airspeed sensor is on one wing away from the prop…"

"Hey, i'm using this calypso as platform with a pixhawk inside. 

It flies great. I'm using a 3S2700 pack I made with panasonic li ion. I'm getting 2.5A current on cruise flight at 10m/s (airspeed). 
It can fly at least 35 to 40 minutes with this…"

nicolas grunbaum commented on AKRCGUY's blog post Invertix 400 - The World's First 3D Fixed Pitch Multirotor!
"Wow, it's been 2 years i do that but never thought someone would say it's the first fixed pitch.... 
Come on. Warthox did it first with multiwii and ultraesc moded. Then I did it with naze32 and simonk esc. 

What invertix is using? "

nicolas grunbaum commented on yann.B's blog post New and simple way to make 3D moves without complex mecanism .
"He uses a reversing esc firmware, like rc cars do, and like simonk esc can do. Props are just normal props ironed to get them as flat as possible. 

I'm testing today my quad, esc flashed with correct firmware and FC firmware modded to be adapted. "

nicolas grunbaum replied to Geir Engebakken's discussion Auto-leveling problem in 2.0.55
"Hi, Just fly with autolevel for 20 secs. Land, and disarm the motors. Reapeat 2 or 3 times, always disarming. This way it saves the auto trim."
