Even though I have heard very glowing reports about the new look RCGF engines, the brand has had such a checkered past that I am somewhat leery of going that route, but in truth their 26cc beam mount engine would be just the ticket for my situation. The VV 20cc generates quite some interest as it comes with a genuine Walbro carb and RCexl ignition, but being a single source engine is somewhat of a negative in my book.
