I have the Giles with an OS 61FX. It fits fine. You'll have to do a bit of cutting on the cowl, as it won't fit inside, but it's no big deal.

My giles flies fine. Landings are a bit fast, but it's no brick. I think it's just typical of an aerobatic model.

I'm using JR 911 mid size servos on the ailerons and elevator. They are mounted in the recommended places inside the plane. I'm using a JR mini 3121 for my throttle. I have a JR 9411 digital on my rudder. It's mounted upside down on the bottom of the plane in the tail. I have 2-56 kevlar pull-pull on it. DuBro pull-pull horn on the rudder.

RX is Hitec Supreme 8channel, mounted on the CG. Battery is 6V niMH 1000mah mounted in front of the CG next to the fuel tank. Fuel tank is DuBro 12oz.

RTF weight is 6lbs. 10oz.

Mine needs down thurst. Plane pulls towards the canopy in knife edge. Plane comes towards the canopy in vertical maneuvers. It also needs right thust.

This is most likely because of the 61FX on the nose. The engine puts out more thrust than was designed into the firewall. I'm sure this plane with a 46 wouldn't need any thrust adjustments.

Aileron rolls are lightening fast. Snaps are predictable and no overrotation was observed. Taxi and take-off was a bit squirrly.
