I built a TRex 450 with an APM mounted as suggested by Randy but am thinking about changing it and mounting it in a different way that would result in the APM being upside down. My question is, can…Continue
"Thanks Robert. I am going to upgrade my servos then. Do you think the HK-922 is a good and affordable choice? In my test this servo performs well on the tail. Would you recommend something different in the $10-$20…"
"I currently have a HK-922 as my tail servo and I am thinking about using it for all 4 servos. Do you think there is a reason that align uses slower servos for the head than the tail? Besides cost? Is slower smoother or better in…"
"I have been flying with HXT900 servos with limited success. I think they are too jittery and too slow to work well with the flybarless head and the APM. What do you guys think? What servo's are you using? I am thinking…"
"Hey guys. I am having problems with my magnetometer. I haven't been able to get it to return correct and consistent values. I haven't been able to find any postings from people with similar issues. Here is what my…"
"Have you looked at the hardware-in-loop for quad rotors? I think you would be able to find or create a flightgear traditional heli model that would work and then be able to adapt the code. I haven't tried to do hardward-in-loop yet,…"
"Glad to hear I am not alone :) I am using double sided gyro tape to mount my APM to a CF plate. Do you think the screws/washers would be better? Have you done both?
By 'sorting out' the main blades, do you mean you…"
"I was telling you all earlier about the problems I had with drift (the heli would gradually roll or pitch more and more and would require more stick input just to keep it level). I haven't had a chance to fly it again or try the hardware…"
"No nothing else changes. All you have to do it recompile the code with support for just one type of GPS and it fits (just barely). My APM_Config.h looks like this:
#define GPS_PROTOCOL GPS_PROTOCOL_MTK16#define MAGNETOMETER…"
