What do you fellas think about Super Tigre Engines? The price on them is unbeatable but I was comparing engines to use for my next plane the GP Reactor, and the OS .46 Produces 1.65 at 15,500 RPM and the Super Tigre .51 produces 1.48 at 15,000RPM. My question is are super Tigre engines good as in reliable, durable, easy to tune, quality overall? Thank you all.
