Authentic Airliners is about to release their update set for the Revell 1/144 737-800. As you know the kit engines are based on the -400 series engine nacelles. Contrails do an engine replacement but can be a bit rough. Knowing the work Kurt does, these should be a great addition.

I have no association with AA but have a few of his kits and can advise they will be of a outstanding quality.
Capt Stu, any idea if Virgin will update the winglets on their jets with scimitars? Ray/Salty will QF do the same? Apparently it saves 2% in fuel burn.
Here is an example if a scimitar winglet on a 737.

I think they look good. As Dylan alluded too earlier, someone will knock one off with a truck.
Cheers

I have no idea what QF's intentions are, TOAM.
It looks as though they may be a very expensive (but cosmetically beautiful) add-on.
In this day & age it all comes down to airframe down-time & unit + engineer cost for fitting Vs fuel savings over the rest of the life of the jet. Figures for this I have no idea, but 2% sounds very attractive.
The best bet would be for the manufacturer have it installed as a production line option to maximise benefits for airliner cradle-to-grave.

However, Boeing/Airbus would probably just copy if with minor changes to avoid a patent infringement.

We did look at them, but decided against. We are getting the 737MAX in 2019 and they'll come fitted to that.

according to one of the engineers I know at westjet, they are cheaper than the normal winglets and MUCH easier to install. WJ just got a new 800 with them on. they are slightly different than the ones on the max but pretty close.
