In addition, the RG-400 has less signal loss compaired
to RG-58.

Hi Zed,
I've had my 701 for eight years and gone through three configurations for
fuel tanks (including a custom nose tank) and would make the following
recommendations to you:
1-Don't install a nose tank unless your using a very light engine and need
little range,
2-place your main tank(s) in the wings where they are close to the CofG and,
in case of an accident
well away from the hot engine parts and the many electrical connections
behind the I.P. and,
3-install a small (8 litre) feeder/collector tank behind the baggage
compartment to ensure a positive feed from the wings when fuel runs low.
This configuration provides a more stable CofG and allows me to have the
battery where it should be, close to the engine saving that long cable run
from the tail. There is lots of room behind the I.P. making it easy to
inspect and do maintenance in that area. Finally and most importantly, the
collector tank allows to safely burn the fuel down to a few liters without
fear of fuel starvation.
My usual configuration is 912 engine with amphibs.
Enjoy the building, its half the fun.
Carl

Carl,
Your fuel tank setup sounds quite interesting!
Does your collector tank allow you to monitor the fuel level in it??
A little more info on your method of attachment back there... do you have
extended baggage compartment and is it placed on the bottom floor skin
behind the access panel or somewhere else?
Thanks
Jon
