Hi!
Yes there is! The ASP (Kyosho GX .40 ) is as powerful.
I use that engine in Q-500 pylon over here in Sweden. It turns a 10x6 RAM prop at 14600-14800 rpm on 80/20 fuel using a Nova Rossi 4 or 4A glow-plug (with both the head shims removed). It's also durable as any other engine.
The only problem is the silencer ,but that is easily fixed with some screws and some high-temp silicon.

I've changed the rear bearing to a Swiss C4 WIB bearing (performance specialties).
