| Steve,
The OS25 should be fine for that one, I had an own design which weighed in at 3 & 1/4 pounds on a PAW .19 Diesel. At first I thought it was heavy for that engine but it was extremely quick !!!. Mine was a single wing design too....but as Grey has stated above ..drag factor comes into it with Bipes but I think you will find that the OS25 should be more than fine due to the extra wing area. (Presuming it is the 2 stroke engine that is !!)
Regards..........Mark.
