I have notices that prop jets almost disappeared form the market. With EDFs and turbine models, it seems like no one wants them anymore, but then people pay lots of $ on swap meets and on e-Bay.
I love my DC F20 tiger shark with an OS 46 FX and my Richmodels Keecat (electric pusher), also have one of the last DC F18 still in the box.
These are lots of fun to fly and I think people would still buy them.
Just my opinion and I hope someone can agree and we'll be heard....
