Vinny003 Posted March 3, 2014 Report Posted March 3, 2014 Hi, guys!I found out it takes several seconds to start the engine and it takes a little time for the propeller to stop rotating after once the engine is shutdown, but in the LES dc-3, the engine startup almost instantly and once I shutdown the engine, the propeller stop rotating almost instantly. I think that should be fixed. I'm using the dc-3 v1.4. Thanks! Cheers, Vincent
Goran_M Posted March 3, 2014 Report Posted March 3, 2014 If you're comparing the Dc-3 to the Saab, then the answer to this question is the Saab is a turboprop. The DC-3 is a standard engine. That's why the Saab takes longer to start.
Vinny003 Posted March 3, 2014 Author Report Posted March 3, 2014 Hi, Goran!Got to! That makes sense! Thanks! It also means it also takes longer for the Saab turboprop to stop rotating than the propeller on the standard engine of the dc-3. Cheers, Vincent

eMko Posted March 3, 2014 Report Posted March 3, 2014 Many turboprops (and SAAB looks like one of them) have a "free power turbine" which is not connected to the rest of the engine. It is rotated solely by the hot gas going from the engine. The free power turbine concept cases a little delay between engine start and propeller moving. The same when the engine stops - the propeller is spinning for some time even if the engine is stopped. I have seen a video on youtube where a guy moved a propeller of ATR-42 just by hand and then hold it for couple of seconds when the engine was starting. However DC-3 has old reciprocating radial engines - imagine something like a car engine which has pistons not in line, but aligned to a star shape and without a clutch pedal. When you engage a starter, propeller starts moving immediately. This reminds me my driving lessons a couple of years ago. I don't know which country you are from, but here (Czech Republic) the cars with manual transmissions are very common. During the initial driving lessons we were taught that "Never stop at the railway crossing. If your car engine dies on the railway crossing, put there 1st gear, release the clutch and turn the key to engage starter - your car will "bounce" forward out of danger zone. Then go by a new battery."
Vinny003 Posted April 10, 2014 Author Report Posted April 10, 2014 Hi, guys!I saw the dc-3 engine shutdown on YouTube. From what I see on YouTube, it takes about several seconds for the propeller to completely stop rotating, but in the LES DC-3, the propeller completely stop rotating almost instantly. I tried to post you guys the dc-3 engine shutdown video from YouTube but I don't know how.Thanks! Cheers, Vincent

We do not have any plans to change this. Thanks!
Vinny003 Posted April 10, 2014 Author Report Posted April 10, 2014 Hi, Cameron!I'm trying to help get the LES DC-3 to work like the real thing as much as possible. Cheers, Vincent
