That looks so sweet, Have a Magnum 91 in a T-34 (hate this plane) looking for a new home. Been looking at this one for Santa to bring me. Keep us posted on flight reports and Frag make sure you have the choke installed on you TT91, Those engines won't run right unless the choke is installed, It acts like a type of veturi on the carb, You don't really need to use the choke but it needs to be installed to run well.

Keep us posted
