Re: Engine, Mags, Bellcranks
I am building std.rg Elite, what are the chances of needing a secondary oil
cooler in the wing root? I live in Texas. Would it be wise to wait and
see how the heat goes on Lyc. IO-360 or go a head and install it? I
do not want to fight high tempertures like I have been reading.
