i just came across this thread, and have to say something. As far as turboing a regular trimmer engine, it CAN be done! will it be as efficent as a 4 stroke or a 2stroke thats been modified for the turbo, NO. but it will up the power on the trimmer. when the intake and exhaust ports are both open, this creates the good ol' scavenging effect which is common in all internal combustion engines. the pressure from the intake charge will "force" the exhaust gas out of the cylinder and fill it full of nice clean unburned fuel and air (much more that would be possible if normally aspirated) which in turn gives you more power. but, that might not always be noticed in all applications, because there are trade offs and disadvantages to some mods. ex: if low end torque is needed, or crisp throttle response. (all turbo'd engines have some degree of lag), but for all out balls to the wall top end power, you dont need throttle response or low end torque. (in most of these applications) as for R/C use, i think this guy may be on to something. although his first product may be bulky and inefficient, he can always use the findings (the plusses and the drawbacks) to better his invention which could lead to a very successful product. im sure that the first few models of most any invention were like this at one point in time, but u gotta start somewhere! and he may also learn/discover something else beneficial along the way. (alot of inventions have started out as "mistakes" or undesired results.) Im only 21 and i can see this.....cant you guys?
