I would include the OS .40 LA -- not that it is a really bad engine, but it is gutless & much too expensive for what you get. The .46 LA is the same size & weight ,but noticeably more powerfull & is only a bit more costly (although it too is not really much of a bargain).
This statement is confusing me
The os .40 LA is the first and only glow engine I used on a megatech skyliner trainer . Once I received a few tips from RCU on starting it , it would hand start without a problem . The only time I dead sticked this engine was due to me fooling with the needle trying to make it run leaner than recommened . Other than that engine in my oppinion , comming from EP powered planes is buy far powereful enough for a plane this size .
