Gil, So let me see of I’m getting this right...you’re putting a TSIO550 in a LNC2 (320/360) airframe? This is not a Legacy (LEG2) but a 320 (LNC2)? Is this correct? If so, may I ask...why?

So no problem. The battery has been moved. The cause is the fact that I installed a TSIO550 with a three bladed prop. It is about 72lbs. I did not move the engine back. I have a standard 550 engine mount. Gil
