| Re: Take a guess was the number written on the crate the weight of the part or did it include the box, skid, bands, etc? |

| Re: Take a guess Generally the weight on the side of a crate is the shipping weight, so it will be higher then the actual weight of the engine. Dry weight |

| Re: Take a guess The side on the box said 428lbs. I dont see how a skid and some straps could equal all that left over weight. Am I missing something |

| Re: Take a guess I just took my commercial multi instrument checkride yesterday and this was asked on my oral. If counter-rotating props are that much safer, why do companies such as Raytheon and Saab still have convential twins? Funny thing is I got it right, and was just a trivial question he asked. Answer to come........ |

| Re: Take a guess It's not necessarily expensive to make counter-rotating engines, but it's easier to only keep one type of engine in stock. The reason most "conventional" twins are conventional is just for that reason. It's easier to swap out the engines when they're the same engine. That's my guess. Any A+P can put a crankshaft in backwards... |

| Re: Take a guess Tallboy is right. Has to do with cost of inventory. If they wanted to have only 2 engines on hand for a convential, they would need for for a counter rotating twin. |
