| Subject: | 914 Mono ground cooling |
Has anyone measured the velocity of air coming out of radiators when 914
Monowheel is on ground with motor at idle and slight above?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fiddling last night with a 5.5" folding propeller on electric motor with a
mock up duct on water radiator, flow coming out of the radiator was to say
the least impressive, inlet size was between PTAG and Factory, prop is
inside intake by about 4".
Weight of prop and motor probably 4 oz., when blades folded frontal area
is bout diameter of US Quarter (27.6mm). Pitch speed aft of prop when
blowing in inlet at about 20mph was probably over 60mph. I need to bring
to hangar measurement instruments for speed and amp draw.
An order is in with my partner Wayne to bring over 2 leaf blowers for same
high velocity testing.
Side benefit may be constipation, running the motor backwards at a very
very low power setting easily constipates all flow through radiator with
20mph at intake which would equate to help warm things up on ground, I am
pretty certain in-flight a low setting would do the same.

I have seen a few people discussing raising the seat back height by
an inch or two to accommodate a larger main tank and then switching
to an alloy tank or simmilar as part of the process of replacing a leaking
tank, just wondering if anyone has looked at this further
