About this Plan

Ace 4-60 Bipe. Radio control sport biplane model.

Quote: "Assembly Manual. Ace 4-60 Bipe. Designed by DB Doc Mathews.

Introduction: The 4-60/90 Bipe fills in the series of plane kits between the 4-40 Bipe and the 4-120 Bipe. The 4-60/90 Bipe retains all the virtues of the 4-40 Bipe and adds easier construction, higher strength, smoother aerobatics and markedly improved visibility. The excellent ground handling and takeoff/landing qualities are retained in the larger version. More importantly, the 4-60/90 Bipe handles much better in moderate to high wind than the smaller 4-40 Bipe.

The 4-60/90 Bipe's flight envelope is broad enough to allow docile trainer-like flying with a forward center of gravity. The 4-60/90 Bipe becomes nicely acrobatic when the CG is moved rearward and the throws are increased. The model flies on its lifting surfaces (as an airplane should). It is not an overpowered projectile that uses brute power for flight. As a consequence, the maneuvers are smooth and stately as opposed to abrupt and violent, making the 4-60/90 Bipe a predictable and solid flier - pure enjoyment, flight after flight.

Now that we're sure you're anxious to start, we won't praise this airplane anymore. You'll find out on the first flight what were talking about!

Read through the instructions and familiarize yourself with the parts, before starting construction.."

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
