Hello,
So im gearing up to build a system using Pixhawk 2. The base frame is comprised of Trex 700 mechanics with a standard style head, not DFC. It has been stretched to 800mm and swings Align 800mm wide chord symmetrical blades. This helicopter also has a large gimbal that hangs underneath for carrying a DSLR, FLIR, SSD RAW recorder and other gear. Now it has been used successfully last year with a standard FBL unit on it, Spektrum AR7210BX specifically. After quite a few tuning and trim flights i got it stable in the accelerometer based "self level" mode so i could focus on positioning it vs having to focus so much on the act of flying. Aside from feeling like a flying cow it moved along quite well although i never attempted anything over 30mph or so im guessing for forward flight. Its more for getting high res aerial photos and videos and a pet project for working with a local municipality's fire and police for uses involving aerial thermal imaging.
My question is, how will pixhawk respond to having a large gimbal hanging under the helicopter? Is this do-able? Im going to be using the pixhawk 2 btw. Im just wondering as ive read many posts about unwanted oscillations and from my experience last year i know that adding the gimbal made using a stardard fbl a chore to get rid of them.
Thanks,
Tim
