Right Thrust
 

Newby question, but the right thrust built into firewalls, is this to counteract engine torque?

Right Thrust
 

Yes.

Depends on the model, some use an off set firewall, some an offset tail, even different length wings. The firewall (or wedges behind the engine mount, which amount to the same thing) is the most common method

downthrust, which stops an aircraft climbing as power is applied, can also be incorporated in the same way.

Normally these offsets are only a few degrees.

Right Thrust
 

No :D !

I understand that it is to counteract the spiral prop wash !

Now can an expert tell us which it is please !!!!

Right Thrust
 

the answer is yes

basically both the spiral from the propwash and the torque of the engine try and turn the airplane left.

to counter this some engines are given right thrust.

so yes it is to correct for the torque of the engine and yes it is to counter the spiral of the propwash.

AH, That explains why I had to offset my motor when building my ARF, My RTF ALPHA (may her soul rest in peace) was prebuilt so I did not notice it. I appreciate the information you guys put out, keep it coming. btw There is not a ama sanctioned field or club within 60 miles of me so any info is good info.....Newbie me!
