Was looking for an engine for the Hanger 9 ARF Cub, that I don't have to BUTCHER the cowl.

Happened onto RCV. Their web site is
www.rcvengines.com.
Has anyone experienced this "NEW"

design, and if so what do you think/advise??
The props are new to me but a 14x14?? The hype is that with the 2:1 gear reduction, larger Dia, then 2x, the pitch

Fuel tank pressure

Problem

Starter Key problem
What do the experts say??
