High Speed Delta - High Speed Gliders - Plan and article showing design of simple catapult glider models.
Quote: - "The large speed range of a catapulted glider requires some trim device between launch and glide speeds, in order to avoid the normal loop or trajectory flight path. One satisfactory answer to this problem has been found in the Blow Back elevator control. This is adjusted to blow back to a down stop at launch and moves under a spring load, as the speed falls off, to a stop so arramged for trimming in the glide. Therefore, straight flight paths from realease to near maximum height can be obtained... "
Quote:- "G'day Steve....Please find attached article on catapult delta glider which may be the one that David wrote about in his request to you. Hope this may be what David is looking for. Thank you for the superb job your doing in preserving all the aeromodelling plans through Outerzone. I am 75 now and love seeing the plans of models I built 50-60 years ago and I am rebuilding some again; great memories; many thanks. Kindest regards, Fred T."

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
