Speed Propeller
Does anyone here have any data regarding the use of using an Airmaster AP42
0 http://www.airmasterpropellers.com/wab487.html=C2-with the Jabiru engin
e 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 Airmaster
would show noticeable improvements in average cruise speed, climb, takeoff
, to handle as well as=C2-the aircraft just fitted with a Jabiru 3300 wit
h no constant speed prop, power-wise.=C2- I=99m a little reluctant
to use a smaller engine under 100 HP on the Zenith CH-750 even though Zenit
h says it will fly with engines with horsepowers in the range of 80 to 125
HP, but I would consider the 85HP Jabiru 2200 if it were fitted with an Air
master AP420 if Constant Speed propeller if I could be shown to get the eco
nomy of a 4 stroke (4gals/hr) engine, with the assurance of no sluggish han
dlings on take-off or climbs.=C2- I was told I would have to register suc
h 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

Speed Propeller
Jay, Per FAR 1, Definitions, an LSA of any type cannot have an inflight
adjustable propeller.
Also, unless Zenith is willing to build and certify a CH-750 as an SLSA
(Special Light Sport Aircraft) per FAR 21.190 and give you the necessary
documentation to meet FAR 21.193e you cannot register it as an ELSA
(Experimental Light Sport Aircraft) per FAR 21.191i(2). You can, however,
register it as EAB (Experimental Amateur Built) per FAR 21.191g.
