20 hours is standard for R/C jets. Remember, these were built for target
drones. Getting your hands on the trick bearings would probably be the key for
the rebuild and knowing the procedure. Nice casting, machining and stampings
compared to the RC versions in the size range. Interesting, nonetheless.
Practical, maybe.

I've been watching this guy for the last 4 months, he had 3 engines originally,
the highest price one is left at $10K.
The problem with these engines is they're rated for only 20 hrs TBO. Not very
good considering they have a separate oil lubrication system unlike the
chainsaw trpe with 5% oil in the fuel. The WR24 uses a 'total loss' lubrication
system where bleed air pressurizes the oil tank which is that cylinder on the
underside of the engine. All that said, I'd love to have one/two. The -8 model
is rated for 240 LbF, not sure how they get another 50 Lbs of thrust out of the
same geometry w/o increased RPM.
Yup, nice engine typical of Williams. Their fans are nice too.

Some for sale on eBay.

Could be a good powerplant or combined cycle core for an air launch project. It
even has an alternator.
