although youve levelled on the ground, theres no reason for this to give you a perfect level for flying. an error of just a few…"

Hi there :)We have the latest version of mission planner, and the arducopter firmware loaded on our Hexa+ configuration. Throttle seems to work just fine, and lifts evenly. Pitch works just fine…Continue

PID?dr1ce315 replied to dr1ce315's discussion Customized Hexa pulling foward when throttle is applied... PID?"We're still struggling with this rig. We've put a brand new APM 2.5 board in it, thinking it was a gyro or accelerometer or chip problem. The firmware has been reloaded/reset 20 times, brand new manually calibrated ESCs...…"

have you calibrated all esc´s the same? have you checked that there isnt a bad motor somewhere on the front ?
i had this problem and it was a motor that appeared to work but was drawing more current than the others and…"

Do gyros go bad often?"
James replied to dr1ce315's discussion Customized Hexa pulling foward when throttle is applied... PID?"i dont know if there could be an error with the upload of firmware to the board, but if youve reset, tried again and got exactly the same result it shouldnt be the problem. the v2.6 firmware for hexa flies absolutely great in my experience, so…"
dr1ce315 left a comment for Mike R."Hey Mike,
My RC Friend custom fabricated the landing gear out of carbon fiber and used struts, and it would probably be more convenient if you don't mind sending him an e-mail, he's more than happy to give you info on how he built it, and…"
dr1ce315 replied to dr1ce315's discussion Customized Hexa pulling foward when throttle is applied... PID?"Well, we just tried to check if the board was not level for some reason. We put a 2x4 in the front and leveled it and tested, and it still pulls forward. We then put the 2x4 on the back leveled it, and it is still pulling forward. …"
James replied to dr1ce315's discussion Customized Hexa pulling foward when throttle is applied... PID?"PID tuning is to control the change of attitude, to get it following your stick or autopilot inputs quickly and smoothly without too much oscillation.
if its consistently pulling forward in stabilize, then its because it thinks its not level.…"
Cliff-E replied to dr1ce315's discussion Customized Hexa pulling foward when throttle is applied... PID?"Check motor axle lengths from the CG/center. Check motor mount tilting/bent.
On the software side, minor roll/pitch on take off is usually a leveling issue. If you auto-leveled, then your APM is way out of physical tolerance--physically level the…"
dr1ce315 replied to dr1ce315's discussion Customized Hexa pulling foward when throttle is applied... PID?"We have used a tachometer to read all the engines while running and when enough throttle is applied for the unit to lift we're getting ~43k RPM on the front 3 Motors, and ~55k on the rear 3 motors...
Is this a firmware problem? …"

Hi everyone!We have customized hexa+ and we seem to be having a problem with it pulling forward automatically when throttle is applied. I understand that the PID setting are crucial when using a customized hexacopter. Here are the specs of our rig:The controller /stabilizer is a Sparkfun APM 1, assembled by UDrones.40 amp ESCs, from Innovative Designs.30 amp Scorpion series II motors from Innovative.Camera gimbal, interchangeable to 3 lbs., with gyro stabilization.13,5000 mah 14.8V lipo…See More

dr1ce315 replied to dr1ce315's discussion Roll is controlling pitch"I wanted to downgrade the software because it was working correctly about a month and a half (or two) ago. I should also say that we did upgrade the motors and ESCs in that time period, but the ESC's have all been calibrated, etc, and as I said…"

"Why do you want to load an earlier version of the software?
I fly with APM 2."
dr1ce315 replied to dr1ce315's discussion Roll is controlling pitch"MP will only load the latest hexa code on the board. I wish there were a way of uploading individual firmware via MP, but I can't find one, and in my perusing of Google I read the only way to downgrade is by compiling the sketch with…"

"Why are you using Arduino? The MP will just load the code for you (and make sure you're actually using the hexa version)"
