Hey Rick, some times i thought you have your landing gear up when I saw your video... when I saw the end I was sure, you forgot it up :))) and next I saw comments...
I have learnt a lot from others over the years on various...only 400-500fpm with me (90kg/200lb with helmet and gear) and full tank (about 16L/4Ga...e for very heavy pilots though (over 240lb with all gear). They expect to get 1000+fpm...
If you have a pair of strobes, and you have a king post, then I would put one strobe on kingpost and the other one right below and in the middle of your main landing gear. My 2 cents.
