mike,

In addition to my scale, my twin-engine and my fully aerobatic planes, I fly bipes because I, also, think they look cool. I currently have a Midwest 'Super Stearman', a Pilot 'Pitts S-2', and a 'Great Lakes.' In addition I have previously flew a 'Bipe Stick,' a 'Lazy Ace' and a 'Tiger Bipe' Each has its own characteristics with two common to them all. They all sink rather rapidly when power is reduced, and they all require focussed attention on power and rudder during takeoff.

I am hesitant to say yes or now to a biplane as your second airplane, without knowing how you fly your LT-40 or how comfortable you are during take off and landing.

As others have stated, IMHO a higher performance plane, such as the 'Tiger 2,' might be the best choice for your second plane. Especially if it is a tail dragger, or modified to be one. Then you can practice/perfect smooth, straight take offs, power on (slight power) approaches and settling to touch down landings, while deciding which bipe you'd like and getting it ready.
