Anyone have experience with RCV 120 engines; I have a over weight scale crop duster and limited cowl size; a Saito 90T or 100T would with a nice scale look; Magnum/OS 1.60 a little too wide; may need more power; thought of the RCV 120

The RCV SP engines are designed to turn a huge prop at 5,000 to 5,500 rpm, they are fine running engines, the SP series are not for speed but for scale applications.

There's a Saito 130 twin that just posted in the classified section. The engine is pretty much 2 .65s mated together. Not sure if it'll fit, but it would definately be more power than the 100 twin.
