Just thought some of you might like this suggestion . . you can't align the IMUs and level the gimbal properly when there is no level surface so when I went out to a breakwater to film the powerboat race I took along a modified tripod and a bubble level . . .No level spot here so here's what I did . . . worked like a charm! Pretty easy to do. If you want to see the race footage I got, go to www.inskyphoto.com . . 1080p SLOW MOTION was good too. I used the platform for takeoff and did a hand catch return. It was 85+Degrees hence the umbrella for shade.
