For sure standard ailerons are fine... Reduce the dihedral by about 1" ..Increasing the size of the rudder and elevators by about 3/4" to 1" is a good Idea... Tigers are almost always tail heavy so dont be surprized if you need to add 1/2 a pound or better to the nose...Keep your weight forward as best you can and you will have a great flying plane...I make mine tail draggers ..I put my landing gear just forward of the wing saddle..That way there is nothing in the wing..Very easy build....I think the kit actually gives you the tail dragger instructions if you want to do the mod but I could be wrong...Its very easy anyway... I have often thought about adding flaps but never have...They dont need flaps but might be fun to have just for the heck of it...Enjoy your Tiger ..
