Well, for me it is hardly an "experiment". I've been flying these engines for years with zero failures. Swinging an APC 16 x 8 at 9400 rpms is some really decent power as well. Both of the planes shown have Homelite 30's in them, and both would go vertical out of sight. I lost the Christen Eagle due to a dumb thumb mistake, but I've had the Giles for 4 years and it flies super with it's Homelite 30cc.
