Build and Fly the Mini Pronto!

The Pronto was a popular three channel sport RC airplane designed by Dave Roeblen in 1973. See the electric powered version I build and flew here:

It can be fun to take an airplane design, in this case the Pronto, and make a larger or smaller version of the airplane. In this case, I found a set of original drawings by Dave, with dimensions, and decided to make a half scale (50% size) version to see how that would fly:

Just take Dave's plans and make every dimension half the size. For example, the Stabilizer was originally 16" wide, I made this version with an 8" stabilizer.

The plane came out very well and weighed about 7 ounces. I used a Flite Test Power Pack A for the motor, ESC and servos. They worked just fine in this model. Good luck with your version of the Pronto!
