Hi Steve, I made one of these Kaman Helicopters, probably about 1971/72. However, I recall that I must have made it too heavy. I see that the article says 11 ounces, 312 grams, maximum. I remember flying mine very clearly, as it would just hover - not climbing, and not descending. It was very stable, but just didn't want to go "Up"!! I can't remember that I tried doing things to improve its performance - such as a different propeller, or "lightening" things, or even more nitro in the fuel? (now I wonder that perhaps the engine was worn-out, or the fuel was not very good?) but I was probably more anxious to use the engine in another airframe. In those days our few engines had many aircraft to power, and I had just bought a Single Channel RC set!! I can fully understand the article where it describes the flight characteristics, and I am sure that it would fly like that - if it was light enough/powerful enough. I think that the Kaman "flight philosophy" was that the lifting thrust comes mainly from the propeller, and the rotor blades just "assist" and provide the gyroscope effect to maintain stability. Best wishes,

Hi Steve/Mary, Thank you for a great site - I still spend far too many hours on it!! Further to my notes about my building and flying the Kaman Helicopter - my brother found a photo of it - from nearly 1/2 a century ago!! [more pics 003]

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.
