Please tell us a bit about your UAV interest

I have been flying RC Helis for many years and recently bought a Gaui Quad. Nice little unit but I need more. Control, stability, size. I have now built a Hexa version 3 .....

Philip Fretwell replied to srinath mallikarjunan's discussion Flipping tendency even during startup
"This can be caused by badly calibrated ESCs.  One motor may be kicking in before the others or at a higher level."

I am worried that the pwm values of each mode on channel 5 may be too close together.  This may be the cause of my hexa getting its knickers in a twist when changing modes. The six values are 1081 - 1265 - 1490 - 1580 - 1690 - 1780 I don't want to…

Just had my third major crash in two weeks.  This time took out 4 props and my receiver .... I think that I at last understand the problem. I have been really keen to use RTL and up to and including .37 it has been unusable for me.  The model would…

"One facility I always admired on the MikroKopter platform was "Chimney mode".
This would allow you to set gps position hold and then shoot the heli in to the air to a great height without the worry of lateral drift.
I have Hitec telemetry to my tx…"

Philip Fretwell replied to Jason Short's discussion 2.0.38 help and suggestions
"I use the level reset facility when at the field by holding full right rudder with low throttle.  This works great but at ehe moment it is set to 30 seconds.  Could this be lowered to perhaps 15 or 20 seconds.  Keep up the good work."

"I have setup my Hitec Aurora 9 to mix two channels within the tx to allow me to use a three position and a two position switch which work together to give me six positions.  The info below is from someone who has setup the Hitec.  Each tx will be…"

I am testing 2.0.37 and although altitude hold on sonar and baro both seem much improved I am having issues with loiter and RTL. When switching in to loiter the hexa moves in increasingly larger circles before I take back control.  I'm sure PID…

I have noticed from 2.0.30 onwards (could be earlier) when I switch to Loiter or RTL and then back to simple mode,  the front of the Hexa is no longer the front. - Anyone else have this problem?

I flew my Hexa this evening on 2.0.29 and other than RTL and loiter issues (suspect major PID tuning is required) the bird flew great. Got back home and updated to 2.0.30 - now I have to hold full left yaw to stop it rotating to the right and I…

For the last couple of weeks my Hexa has been flying like a dog ....Just run planner to install 2.0.29 and my world is back in order.  A massive improvement with sonar altitude hold working the best ever.... The most stable in ages and haven't had…

The settings below are available in APM_Config_h.  I understand that this is to allow in-air tuning using channel 6 but what does each function do?? Also I am using a nine channel TX/RX and I use channel 6 for camera pitch.  Are there any other…

I have no control over the yaw in 2.0.25.  When I check in CLI and move the left YAW stick left - centre - right i get 0 - 2200 - 4200 in radio test mode. I have run radio setup again and it stays the same.  How can I change my radio…

"I am using the Hitec Tx with full telemetry, temperature of all ESCs, height and speed via gps and also RPM for one of the props.
 
I notice that with 10" props on my home build hexa, the props run at about 5400rpm and with 11" props they run at…"
