Engine Thrust 0/0

[Dean Pappas]

That's right, Nat.
The best compromise is to make all the funny angles as small as they can be. Of course, fully cowmling a four-stroke puts you in a terrible poosition, regarding right thrust. 
The old UM-2 had equal chins both above and below the centerline, right? That didn't need right thrust either, didn't it?

As pointed out, using right thrust and/or throttle-rudder mix it is possible to trim adverse thrust effects of the typical pattern plane for only one flight condition.
 
I should also point out my design, the VooDoo Express, requires no thrust offsets and is in trim in all flight conditions and all power settings.
 
FYI, Richard Lewis has a superb version of this airplane flying and can provide plans for a nominal fee.

Throttle to rudder mix or right thrust ?
Both practices meet our needs, separately or in combination. The most useful need for right thrust ( or right rudder ) is in the vertical up line. The most apparent need is early takeoff. The amount needed for takeoff, vertical up and straight and level ( upright or inverted is irrelevant ) are each different and all are nominally at full throttle . We can't provide the difference with either or both methods.
 
The reason we are happy with our trimming is because the thrustline does not need to be highly accurate. We seem to be unable to descriminate with an error of maybe plus or minus 0.3 degrees ??                     Nat

 Here is another link on Chips throttle to rudder mix ideas.

Vincent,
 
I think Chip uses about 2 degrees or as little as possible and then adds a throttle to rudder mix curve.
 
Chip had an article on this on RcUnivrese under his forum.

Finally, I had chance to read the last K-Factor (October).  I read an article Practice and Trimming by Scott Covey (District 7 column) and it was interesting the information in regard 0/0 engine trust.  However, it does gives too much details besides that the results were good.  I remember checking Chip Hyde Scandalous at Nats. and I don't think I could see 0/0.  At naked eye it was evident that it has right thrust.  I am interesting in finding real feedback from experience pattern pilots using 0/0 engine thrust.
 
Best regards,
 
Vicente Bortone
