<DIV><FONT face=Arial size=2>Hello - I have a BME 30% Yak, (and had a
TOC/Aviation Models Yak), and both pitch to the canopy when power is reduced in
vertical climbs (also on level cruise power deceleration, too).
Elsewhere, fly well, and doesn't exhibit bizarre incidence problems,
and both needed UP elev. trim for level upright flight.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>ON the RCU threads on these two, owners report
needing to carry up elev trim, also, but haven't gotten any insights on the
engine thrust question.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have measured, and there is currently NO up or
down thrust in the motor referenced to centerline.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Could these planes actually need some UP
thrust??</FONT></DIV>
