What is the cause?
Hi All,
My Composite Arf 2.3 Extra pitches up when I reduce power.
The CG has been checked and is on the forward limit of the manufacturers instructions. With fuel the CG would be even further forward. In level flight it requires about 1/4 forward trim, when I reduce power it then requires more forward trim to stop it climbing. The thrust line looks ok.
Has anyone experienced this trait with their 2.3 or any other similar model? If experienced how was the problem fixed.
Happy flying,
Airtourer

RE: What is the cause?
1 of 3 things.
wing incedence is off.
the elevator is off a hair.
there is down thrust in the engine. when the power is cut there is nothing pulling it down.
how does it performe? if it's kinda slugish then it is nose heavy and one of the above is also wrong
if it's really snappy then then your instruction are wrong which has happended to me more than once on several models and you need to add some more weight to the nose
