Is the Home Point established on take off by the position of the contoller or the bird?  Relevance, if I'm standing along a treeline and fly the bird into the middle of a field and hit the establsih home point button, is the new home point following a RTH command the center of the field or the original location of the controller along the tree line.

Its the controller - otherwise the bird would just land at its position in case of a connection loss. Imagine that


Before trying RTH however make sure its set high enough to not crash into the trees in case you stand behind them.

Thats possible. I always take off very near the RC so there never was a difference.  There are 3rd party apps which have this point draggable but I never used this.

Yeah... for most people, it would likely be the same. I just tend to land straight on the field fo ...

Ultimate Flight or Litchi or both of them.

Paul,

Thanks for explanation and flight log screen shot, that clarifies everything.  I like the idea of flying the bird out and resetting the Home Point in the middle of the field to avoid a RTH to close to trees in the event of a problem.

A tunnel will switch it to Atti mode its likely to drift away and crash in the tunnel within a few moments. Never fly in a tunnel there may also be heavy wind.

I wanted to fly under a small bridge and to measure the hight I just flew under it and ascended. Was a bad idea it lost GPS and started to drift I just got it out centimeters away from a crash I will never do this again.

Atti-mode practice is always a gooooooooood idea.

One never knows when GPS might crawl up its own  ...

Atti alone is not the problem but in a tunnel it can crash in a second with the wind.  Inside a canal maybe there is less wind if its not only one tunnel but thats a special case.

That is why atti mode practice is so essential.

At least wind setup in the simulator would help. We would know them how strong wind it can really fight and also how big the effects of their removed wind compensation is which was a idiotic idea anyway..

Hi Paul, if you're looking for a good sim you might try Phoenix. It uses photo realistic back grounds, Stonehenge, airstrips, the Grand canyon etc, and it employs awesome wind control settings such as direction, strength and gust rates all with real world variations ( southerlies in my home city ever come from one direction, they to and fro almost constantly.   Perhaps not so useful for the I1 which tolerates cross winds fairly well and who would fly truly turbulent conditions.

Btw I have fitted my I1 with prop guards for indoor or even canal tunnel work; very cheap and effective insurance!  It's comforting steering my I1 into walls and branches and harmlessly bouncing away intact, who need fear Atti mode again?
