Why is the RTH altitude limited to 50 meters. It should be 121 meters.  I fly in areas where trees are in excess of the 50 meter limit and the forward avoidance does not work with small tree limbs.

It's not limited to 50 metres.  The only limit is 500 metres.    Choose any height you want up to 500 metres.

You can change the RTH altitude.  I set mine to 50 meters, which is well above any treetops even if I launched from one of our floodplain fields and wished to avoid trees on top of the hill on our farm.

Agree with the above. You can change the RTH altitude in MC settings(20~500m).

those are some tall trees!  Most trees in my area don't get over 25 meters.

I stand corrected.  My aircraft was not connected.
