About this Plan

Challenger. High performance 2m competition sailplane.

Also kitted by PMP (Precision Model Products).

Quote: "This high performance two meter sailplane has both the eye appeal and flying ability to make it a definite addition to your collection of models.

Challenger! The name implies something new and exciting, and that is just what this new 2 meter sailplan design is. I have always admired the soaring hawks of California. They possess great ability to ride light lift and still have the speed to sail right through sink areas ib search of updrafts.

Now you can fly a sailplane that does just that. This high performance sailplane designed for multi-task competition or just plain fun flying is great at both. Soaring slowly in light air or speeding through sink areas.

This is possible because Challenger uses a proven airfoil (which has a very wide speed range) - the Eppler 205.

Challenger has the ability to turn into a light flat circle while riding a thermal upwards. You can tell easily when you have entered a lift area with this design.

High starts are an absolute breeze, stright up, no rudder control is needed. Pitch control is very good because of the full flying stabilizer. The T-tail design was chosen because it lets the flying slab ride in turbulence-free air - besides, I think they look great.

If you're into slope soaring you will just love flying this machine. The speed it can obtain in even a moderate wind is breathtaking. When some of the other designs are just barely able to penetrate the wind, you'll be flying patterns with your Challenger..."

Quote: "Steve, Please see attached plan for your great website. This plan is from RCM June 1981 edition, saw it as a kid and finally built one. Test flight went well today, a really smooth 2 meter sailplane with 580 sq/in. Should weigh 26-29 ounces according to the plan. Mine weighs in right at 27 ounces with electric power up front and a 1800 mah battery. Thank you for what you do, great service to the modeling world. Take care,"

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

What a surprise to see my design after so many years, I hope someone will enjoy building and flying it.

Hi Peter!
I had a 2M Challenger back in 1983 and loved it! Was my absolute favorite glider!
Thanks for the life you gave it!

* 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.


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.
