Hey flipstart, here are mods I did on a TigerII kit last year. Flies like a dream.


Mounted the engine sideways (OS FS70).

Cut off the front fuselage "cheeks" and installed a balsa engine cowl similar to the Ultra Sport 40.

Glued the fuel tank hatch to the fuselage for front-end strength.

Reinforced stabilizer and fin trailing edges with hardwood strips.

Made symmetric, open wing tips. (sheet wingtips braced top and bottom).

Added ½ inch to the rear of the rudder.

Made it a tail dragger: Moved main landing gear blocks in front of the wing spar and angled them forward, placing the axles under the wing's leading edge.

Fabricated & installed a tail-wheel setup similar to the one used on my Ultra Sport 40.

Countered the extra 4-stroke engine weight by placing the battery behind former "C".

Knocked 1/2" off the recommended dihedral.

Replaced the aileron torque rods in the kit with 1/8-inch torque rods from the local hobby shop - inserted them deeper into the ailerons and epoxied them into the ailerons.
