I'd take another look at it Hiway.... 1300g+ is what my Phantom flys on all flights so weight isn't the main issue. Its the stability that is the kicker. Some retract servos allow you to mechanically limit them (so they stop at 45 degrees). That would get the legs out of the way of the camera and, while not looking 'fully up' they might help keep the CG manageable.
Also iirc you were playing with gains at one point on the P1.5 thread and had them pretty high. I had to turn my gains waaaaay down on the F450 to tune out the oscilation caused by those legs. ...:
Now I am really cornfused...
I took the afternoon to dwell on everything- absorb what you said- pour over a few vids, and then I went back up and tore the Phantom down to be sure there were no anomalies on the wiring, or the order of motors to the M1-M4 on the Naza... just grasping at straws.
I came to some very uncertain conclusions:
1. I cannot be dealing with weight- you have confirmed that my weight is within the realms of flight.
2. Despite you pointing out the inherent issues with CoG and the Naza, and weight to the sides and not under, I have to point to thetac's vid where he has his dual batteries side mounted... I can promise you that my retracts weigh far less than a lipo 3S... much, much less- in fact, both of them combined weigh maybe half, if that, of a single regular 11.1v lipo 3S... so I am truly scratching my head.
3. There is no doubt in my mind the motors seem to lack power- my gains are at 125 across the board and yaw is at 100 (as well as the column next to it- forgot it's designation) Now I can drop those, but this bird flew those 2 side mounted lipos with a goodluckbuy cnc gimbal with that massive landing skid seen in thetacs vid... and with smaller props I might ad. Why would this config not get off the ground more than a foot? Then again, perhaps it would, but I was not willing to take my brand new CM3000 for a death trip, and there was little doubt the Phantom was not willing to fly right.
...so I am not so sure now that my placement is as much an issue as some other possibility. I could put the t-motors in- but I don't really think my stock motors are the issue- they sound fine... not even the telltale sound of bearing wear as I have heard in others... so this is truly puzzling me.
I also am at a loss to conceive, or maybe my spirit is a bit scuffed right now, at how to reconfigure these to be placed lower without adding a bit more material somehow- I was so happy with this simple fabrication.
As for the 45 degree stop- these are 90 degree fixed with a shutoff on the draw... the guy makes 45 degree, and I agree with not needing them to move back very far, and in fact, with basic yaw follow, fixed skids are fine bar the front end of the skids on pitch with wide angle- but that was not the goal and I am not trying to move the posts.
I suppose a day or two, and some more staring at it... maybe I will put it under my pillow and try osmosis... but I am not as defeated thanks to your input, and instead now further into the woods in what could be causing my trouble.
