-=0ADoes anyone here have any data regarding the use of using an Airmaste
r AP420 http://www.airmasterpropellers.com/wab487.html=C2-with the Jabiru
engine preferably using the smaller 2200 on a Zenith CH-750 or comparable
sized plane?=C2- I=99m wondering if the Jabiru 2200 /w 85HP and Air
master would show noticeable improvements in average cruise speed, climb, t
akeoff, to handle as well as=C2-the aircraft just fitted with a Jabiru 33
00 with no constant speed prop, power-wise.=C2- I=99m a little relu
ctant to use a smaller engine under 100 HP on the Zenith CH-750 even though
Zenith says it will fly with engines with horsepowers in the range of 80 t
o 125 HP, but I would consider the 85HP Jabiru 2200 if it were fitted with
an Airmaster AP420 if Constant Speed propeller if I could be shown to get t
he economy of a 4 stroke (4gals/hr) engine, with the assurance of no sluggi
sh handlings on take-off or climbs.=C2- I was told I would have to regist
er such a plane with an
Airmaster as an Experimental-LSA as opposed to just an Amateur Built-LSA.
=C2- I=99m not certain of the repercussions, cons or pros of regist
ering a plane one way or another, but for the sack of fuel economy and depe
ndable power when needed, I=99m toying with this idea of a CH-750 wit
h a Jab 2200 engine and an Airmaster AP420 Constant Speed Propeller combo.
=C2- I would appreciate any word, rumors etc on this topic and realize th
at such a combo would be rare here in the States, but may not be unusual in
Australia, New Zealand or Tasmania since both the Jabiru and Airmaster are
products of that region. =0A=C2-=0AJay Parker=0A =C2-=0A =C2-=0Ahttp
