[@Mexmex1975]

0:54 0oooooooh that sound!!!!!!!!!!!

[@robertlafnear4865]

I WANT ONE , stand and all.

[@avonaero1]

The video is of a helicopter engine and yes the turboprop variation exhaust does go down

[@adammwangi9959]

How do we load this engine to avoid overspeed

[@florenciaperez3375]

The fuel governor has a overspeed mechanism. It does not depend on load, just n2 rpm

[@michaelsitterly1495]

I have for a long time wanted to put 1or 2 in a boat...i seen people have done it...anyone have any idea on how much one would cost that is timed out but runs....

[@FredtheDorfDorfman1985]

Just saw an ad for a 420 shp 250-C20B, with most major parts with at least 75% life left, was going for $139,000.

Agent Jay-Z just rebuilt one. Oh, so cool!

[@juanarce6405]

I need a test bench endorsed by the roll royce

[@malibustacy3606]

Help me to understand this for a sec.... this engine shown here is actually upside down compared to what it's position in an aircraft would be ?

[@killerdoxen]

Depends. How it is here, is usually how it sits in a helicopter. It’s flipped exhaust side down for turboprop use. Some manufacturers may do it differently.

[@malibustacy3606]

@@killerdoxen Thank you

[@moncarlomillor3293]

I want to make one with my own hand that’s why I want to go abroad and make it into motorcycle just like y2k

Y2k engine

[@nickwayne5285]

One thing this guy did that you never do.... through fuel to the engine and take your hand off the control. If ITT rises to much you need to cut fuel ASAP. Always keep you hand on the throttle during starting and be ready to cut fuel... that is all.

[@Kussler88]

Bro, you can just slap those switches downwards in like .1 seconds.

[@marcoarko4751]

Not good Videos at all should show running Turbines and thrust of the engine

[@evanscm3]

its a turboprop / shaft... thrust doesnt come into it.
