No-one can deny the lure of a four-stroke radial. The engineering, the sound and the sheer presence is enough to have us reaching for our wallet before we've even considered what to put it in. Fortunately, at a very useful 64cc, SC's range topping radial is perfect for a 1/5-scale warbird (a Corsair, perhaps?) or something more sedate like a 1/4-scale Stearman. The options are many and varied but at the end of the day it matters not what you bolt it to, the pleasure and satisfaction of owning and running this piece of precision craftsmanship will be all the reward you need. With smooth throttling, the ability to turn a huge 22x8" prop and a burbling 2000 rpm tickover this is undoubtedly the finest affordable 64cc radial available. There's no getting away from it, round engines rock.
