Default RE: Down Trust and Angle of Attack


ORIGINAL: garywi

Question. If my engine mount has down thrust (5 desgrees), the plane will have a tendancy to climb when throttle is applied right?

Kadet Senior ARF. I want to remove the down thrust for my Saito .91.

I recommend to try to keep the down thrust as it is first. ARF manufacturer must have tested the airplane
and have concluded it needs such amount of down thrust to fly right.
Or your airpane wouldn't climb when you add power and you wish to reduce/remove the down thrust?
Then it looks like you can reduce or remove the down thrust.
As you say, there are other factors, wing incidence and C.G, which affect the flight characteristics.
