Usually about 40% is removed and a new fire wall installed with about 3deg right thrust built in straight away.

No need for tail weight and greatly improves the looks.

Other mods include, tail dragger, larger ailerons, flat wing (looks better than anhedral even though it isn't quite as good)

and Stab on top of body instead of bottom/Split elevators and a larger traditional shaped rudder extending to fuselage bottom.

Last but not least, British roundels.

Sounds awful? I'll post some pictures on Monday and you'll be converted.
