STM Speed and Rangfinder - TRUE Terrain fellowing

Dear all,

I am new to px4 and I am very impressed by all the features. I normally use Betaflight or some similar Software for my racing drones. Now I would to build a drone that is really capable of the terrain fellow mode, even by “higher speed” – around 50km/h. For range finding and altitude Hold I would like use the following: https://www.terabee.com/shop/lidar-tof-range-finders/teraranger-evo-600hz/

my question is: Do you guys think – with two of these modules pointing in front and one pointing below - the F7 STACK will be fast enough to render the “normal flight” and also the input of 3 rangefinders as well?– is it even possible to add 3 rangefinders in px4? and perhaps some of you have even better ideas for terrain following?

I don’t want use the terabee HUB, because the drone is supposed to be as maneuverable as possible in a 5 inch frame.

Thanks in advance!
