Alpavia RF-3 (oz3806)
About this Plan
Alpavia RF-3. Radio control scale powered glider. Here is Owen Kampen's Alpavia RF-3 from Flying Models magazine issue 09-66. This model was featured on the cover as shown.
Quote: "an attractive scale model with fine flying qualities. Though an excess of dope brought the weight up to two pounds plus and a wing loading of 14 ounces (I'm sure you can do better) it has a nice flat glide and is quite capable of thermal hopping. The plans are scale, with the exception of the increased dihedral and enlarged stabilizer, which combine to give a flight pattern as stable as many high wing jobs. As a rudder only design, it is very responsive, using the Adams Dual Actuator on 4.8 volts (4 nicads with 3.6 tapped for the RCVR). Though the original has an NACA 23015 airfoil, a change was made to a modified semi-symmetrical section with a rounder leading edge, maximum thickness further back and a flattened section on the bottom-rear for easier building. This airfoil has excellent penetration and good stall characteristics. It has relatively low drag on a wing of this size and as a result the plane moves out somewhat faster than expected on only half throttle. An Enya TV .09 was used for several reasons; While a hot .049 would be powerful enough, the wide cheeks present a lot of resistance to a small prop, so it was decided to go to the larger engine using an 8/4 Cox prop. As nose weight was needed, the Enya served that purpose better than a lightweight and its throttle lended itself to an easy arrangement for manual adjustment..."

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

ScaleType: This (oz3806) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Fournier_RF-3
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* 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.
