PRECEDENT BALSACRAFT Bi-Fly 25

The Bi-fly25 is a lightweight biplane for motors from .19 to .25 cu ins. It has an all balsa construction to help keep the weight down and will fit, filly rigged, into the boot of all but the smallest of family cars. The performance is sparkling. It's of course quite normal that when the manufacturer designs for and recommend a .25 motor, some modellers will immediately plan on using a .40. Bi-fly25 will certainly take the extra power but beware of excessive torque reaction especially on take off.
