I hadn't used my phantom for a while and tried using it yesterday and it didn't have enough power for a take-off. Tried several fully charged batteries, lights were all good but it didn't even look like taking off. I have been playing with it and fitted wide legs and Chinese camera gimble recently. I also removed the prop guards and started putting in the longer screws before realising they had bottomed out. I don't think weight is an issue but am concerned I may have damaged a motor with the long screw. Is there a way to test the motors as they are all spinning, hard to tell if all are same RPM. I made changes to the camera gimble settings in the software and wouldn't have thought that would be an issue. I also made use of the internal power lead to power the gimble. Any suggestions would be helpful.
