Sparky, IMHO Laser 4 stroke V's are perfect for scale applications, the V aragement lends it's self quite well for in cowl applications. Yes they cost a bit more than Satio or OS but they are difinitely worth it! They seem to tolerate the heat within a cowl and, at least mine, dosen't require any on board glow for reliable performance. I have the 300V and it will swing a prop just as good- probably better than a G62. And very, very smoothly. The only draw back is it lite weight, the planes that are disigned for this type of power usually need the nose weight. I am guessing here, I haven't actually put either my G62 or my 300V on a scale, but it seems that the 300V is close to half the weight of the G62. When deciding on buying a new engine I always try to get the one that lends itself too a multitude of applications. The opposed twin lay out really is limited to Cub type planes, or very large round cowled planes.
Anyway, Proctor Enterprises, www.proctor-enterprises. com , sells them in the USA, and the Laser site in England is www.laserengines.com .
