Thanks Bill,  I read the drawings again and they reflect what you say.  Don't know how I got it so wrong but you saved me from probably a disastrous mistake.

My understanding is that when putting in an offset, you put the center of the prop on the thrust line and change the thrust line of the engine to match the offset.  So you would get an offset of the rear of the engine 0.75” to the left in this case.

 

I am building a Lancair and have absolutely no idea when discussing RVs.  :>)

Hi, I'm making my engine mount and I just want to be doubly sure I'm getting this right.  The engine offset as I understand is 0.75" to the right of centre as seen by the pilot for the following setup.

 

RV8

Renesis RX8

RD1C

 

Thought it would be best to confirm now prior to welding.

 

Thanks

Greg
