Airflo Glider (oz2617)
About this Plan
Airflo Glider. Free flight towline glider trainer.
Quote: "Having now read the first three chapters, you are no doubt itching to get building and there is no better model to start with than this simple glider. We are keeping written instructions to the minimum, as the step-by-step sketches below will make the actual building quite clear. The flying notes at the end of the chapter are important, so please read them carefully.
Having traced the various parts of the plan, transferred them to the balsa sheet and cut them out, start with the fuselage. Every so often look along the fuselage from either end to see it is not twisted. When completed, it can be given a thin coat of dope. Having rounded all edges, mount the tailplane and fin squarely on the rear of the fuselage. If you lightly dope these parts, do it before assembly, and pin the part to the board while drying to avoid warping. Do the samee for the wing.
When completed, balance your model carefully by inserting lead, or a peice of old cement tube, into the noseblock recess. Balance point is 1-1/8 back from the leading edge.
Flying Notes: Hand launch your glider into wind, pushing it forward gently, pose pointing slightly down. Do not 'throw' the model. A straight glide, the model landing about 20-24 ft in front of you, is what is required.
A steep turn to the left is cured by bending the fin trim tab about 1/16 in to the right, and and vice versae (model viewed from the rear). A dive is corrected by bending up the trailing edge of the tailplane slightly.
A stall (model climbs steeply and falls backwards or dives) is corrected by adding to the noseweight.
Unwind about 80 ft of thin thread and tie a small paper clip to the end. Get your assistant to put the clip on to the front hook if the day is breezy, or on to the rear hook if the day is very calm. Then begin to run forward slowly as your helper releases the model. On windy days it may even be possible to tow the the model without moving forward at all.
If all is well the model will tow up straight, and, by slowing down, you can release it from the tow line at the top of its climb. Should the model swing either right or left, slacken the line immediately. If a steep bank develops, drop the line. Steep banks can be cured by using the trim tab as for hand launching. Practice makes perfect. Gliding really is fun.
By the way, store your glider (and in fact ail your models) in a dry place. Damp will warp your models and prevent them flying well. "

User commentsHi, I don't know if this is sufficient quality, but I was moved to build the Malmstrom Airflo glider [main pic] after watching John Woodfield's video. I used the plan in my treasured copy of Eagle Book of Model Aircraft, but modified it somewhat to use as an RC slope soarer. A bit heavy at 150 grams! Cheers,

I built this beautiful and very simple model some years ago [pic 006]. It is an incredibly good flyer despite its size. I think it is the perfect beginner's glider for young modellers. Ray Malmström's designs are so well conceived, easy to make and excellent flyers.

John Woodfield has recently converted one - without any change in size - into a 2-channel slope soarer. It flies incredibly well. Here's a link to the video: https://www.youtube.com/watch?v=_fHUqmQmZqY

* 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.
