RC-Hangout

A friend 3D printed a camera bracket to my 450 to hold my gopro. It works pretty good. The jumps you see i suspect is the camera might not be 100% fixxed in the camerahouse.

Looks good. Would love to have a 3D printer

That's pretty cool! Did the 450 behave much differently with the added weight on the one side from the GoPro?

Thanks. That was what surprised me alot. I did not feeled just any different in how the helicopter behaved. It feeled pretty much as normal. The helicopter had not any problems to carry it at all.

That's really cool, Tomas! Well done!

im surprised your cg must have been way off, FPV next mate.

I had a talk with a friend who watched the video and he pointed out something that i need to try. I might have to high rpm on the rotor. I gonna test to lower the rpm in the next test to see if it be better.

This might sound stupid lol but what means cg ??

center of gravity is the balance of you heli, if there is to much weight to port, starboard, fore or aft the craft will want to drift in that direction, your FBL system will try to correct for this error and probably will to an extent, but when the FBL corrects the cg error (be it battery in the wrong place or go pro strapped to it) it uses available servo throw, this could make the heli hard too fly or unresponsive on a particular axis due t not having full throws due to correction.

If your craft is balanced it flys way better

Was out today and did several testlifts with different RPM´s on the rotor. That was interesting and i have found a RPM that make the picture alot better. I will upload the testflights soon. And about the CG i dont feel any difference about that with the camera on the bird.

Here is 7 short testflights there i testing different RPM´s i think i have founded good settings now. I see test 4 and 5 good ones.

I messed about with a camera on my 500 for a while but was never happy with the results.
Multirotors seem so much easier to get good video from, and are far easier for FPV.
My poor old Trex 500 has not seen a battery in over a year.
