<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>With only 5 flights and a total about 70
minutes run time, the total power has yet to be realized. Knowing this, it
still has quite enough power out of the box. The carburetor operates similar
to a perry carb, in that the low-end and high-end adjustments are on the same
side of carb body. The carb barrel rotates fore and aft, without the
side-to-side translation of a twin needle design where the low-end needle comes
in and out of the spray bar. It is super slick. This, combined with the twin
plug head makes for some clean "zippy" throttling. So far, it
seems like you can "fly" at any throttle setting you want without
loading-up or having trouble accelerating/decelerating. The rpm is increasing
and decreasing incrementally with the stick movement. I have it setup where "1/2"
throttle yield ½ barrel opening, full throttle has full barrel opening. Sounds
simple, but is something to check. If you use the "end-point"
electronic adjustments of the transmitter, you might not have equal + and -
barrel movement. I can't see a reason as of yet to use a throttle
curve. Setting the servo end-points where the total travel needed is split
50/50 between upper and lower stick positions seems to have done the trick so
far (again, ½ open barrel correlates to ½ stick).</span></font></p>
