67M20F Posted March 20, 2010 Author Report Posted March 20, 2010 So I was allways told on snowmobiles that 1Lbs of roatating weight, is like 7lbs of dead weight. Think this is true on planes, don't know why not. Quote
67M20F Posted March 20, 2010 Author Report Posted March 20, 2010 And how much do you think 25.5lbs that far out will effect it, it would move your CG forward and I think that will slow it down. Quote
skyking Posted March 20, 2010 Report Posted March 20, 2010 I saved 7 pounds on the Scimitar prop too. Quote
67M20F Posted March 22, 2010 Author Report Posted March 22, 2010 Just got a quote from Ying Ling propeller, 8754 for a 3 blade scimitar MacCauley Quote
Immelman Posted March 22, 2010 Report Posted March 22, 2010 Just curious but can do (or do you want to) share some details on what happened? Porpoised landing and plant it nose first? if you would rather not say I understand & respect that completely. Quote
67M20F Posted March 22, 2010 Author Report Posted March 22, 2010 My partner was coming in from 10.5 and had to get down to 2.2, came in hot and high, knew he should go around still tried to land, forced it in, and porpoised, didn't know he had struck at that point and went around to late, came in and made a nice landing. The thing that spooked him the most was the fact that he went around with a prop like that, and that the engine could have come apart. Lesson to be learned here is never try to force a mooney land.

Alan Fox Posted May 23, 2010 Report Posted May 23, 2010 I dinged my prop about two years ago , when the AD came out , and the Scimitar was not yet released , and you had to wait 3 to 4 months for a Hartzell ... I did a little research and found out that the props on the scouts were the same prop , Got one for 5500 from a guy that did an mt conversion.....This is a popular upgrade for the scouts , so there are a lot of these props out there... You will have to send the prop out to get the blades reduced 1 inch ... The scout blades are 7666, while the mooney blades are 7666-2.. This will cost about 500.00 and the prop shop will tag the prop and change the blade Part#s And the best part was I got 500.00 for the spinner... Good luck Quote
Alan Fox Posted May 23, 2010 Report Posted May 23, 2010 Try contacting mt prop , maybe they can steer you to a scout owner who converted to an mt Quote
Alan Fox Posted May 24, 2010 Report Posted May 24, 2010 Lycoming says teardown is not necesary , You dial the crank and if it is in spec , you remove the accesory case and inspect the gears and replace the bolt and lock plate for the crank gear... Quote
Scott Aviation Posted May 24, 2010 Report Posted May 24, 2010 what constitutes a requirement for just a crank dial in and accessory case inspection and bolt replacement versus splitting the case and having the crankshaft, camshift etc NDT'd ??? Im curious as I will be going through this myself, my engine had a prop strike from a gear up as the engine was at low idle?? Quote

Alan Fox Posted May 28, 2010 Report Posted May 28, 2010 There is an AD from Lycoming says the procedure for prop strike inspection , and the procedure is dial the crank , I think the spec is .006 runout on the face , and .003 on the side , (I know that sounds like a lot , but i think that is the spec) , if it is in spec , you remove the accessory case and visually inspect the crank and accessory gears and put in a new lock ing plate and crank gear bolt , about 50 dollars in parts , and 10 to 15 hrs in labor, Contenental makes you do a tear down....
