The place where you have to watch out the most with the bipe is when you lose power. Most biplanes lose airspeed QUICK when the prop stops.

Another place you can run into problems is most biplanes are taildraggers and topheavy with relatively narrow landing gear. That makes take-off and landing without dragging a wingtip a little harder...

Its not really that biplanes are inherantly harder to fly... its just that getting them set up correctly is a little harder than a monoplane (the upper and lower wings have to be corectly alligned to each other or you'll have problemes.) Also they tend to be shorter coupled so the control throws don't have to be as large to get the same reaction as the typical monoplane.

If its set up correctly and the control throws are set on the mild side... its nearly as easy to fly a bipe as it is to fly a monoplane with the same wingloading and power-weight ratio.

If you understand what the effects of the differencees will be... you should be better prepared to handle the airplane.
