Here's my Extra which is essentially the same plane (both of these planes used the same wing however the CAP is shorter coupled with the placement of the stab forward of the vertical fin) with a Quadra 52. Didn't get many flights on it before selling it. At the time I wasn't interested in 3D so I can't say if the engine would hover it. I suspect it would. Very nice flying true plane. Very clean on the uplines. These planes were designed by Mike McConnville when he was with Midwest. I would look into the ZDZ line of engines with this size of plane today. Lighter weight than the Q-52 and more power in only the 40cc than a G-62 Zenoah. I would expect the Brison to give unlimited performance. The plane is capable of anything the pilot is. Vertical performance is a direct relationship with thrust to weight. In other words the lighter the plane and the higher the thrust the better the vertical performance.
