RE: Skymaster F4 pipe and wet start
In matter of fact, I never use shut off valve on my models and never had any problems, for what I have noticed, there are more cases to have problems with the cut off valve than without, this is the reason why I prefer this way, maybe one day I might change my mind and if I have to put a shut off valve I will place it before the pump at least will not in put any pressure on the fuel system.
I also do not use any switch for the turbine battery I connect it direct to the ECU, believe me, the more accessories we use in between the more things can go wrong, this is my opinion, of course, we all have different approach on the same matter, I have been flying jets quite for some years and what I am saying here has been very positive but does not mean I am 100% correct.
Please forgive me the ones who do not agree with me.
