Ascender - General purpose thermal soarer model.
Quote: - "Interest in 'flat field' soaring certainly seems to be on the increase, judging by entries in this year's main events. And judging, too, by the number of enquiries coming in about Hi-start launching, kit models - and thermal soarer plans.
As we have only one of the latter in our range to date, I thought I would make a 100 per cent increase by adding my own model, which seems to be a reasonable sort of tow-line glider (albeit originally a 'bitsa') and while doing nothing outstanding has managed to put up a fairly respectable and consistent performance.
Ascender tows up very well on the line (so I'm told, by those who have done all the towing - I just stand still and steer it up!) and managed to place sixth in the 1970 South Midland Area Championships, out of 29 entries, with its first three flights...
The aerofoil section is Gottingen 532, which worked very satisfactorily on my first r/c glider. Silent Knight (1963), and the polyhedral also seemed a good idea. The huge rudder is (hadn't you guessed?) borrowed from the Soarcerer (oz8762) where it has amply proved my point about 1/3 fin and 2/3 rudder being the best proportion for use in all conditions, with proportional control..."

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.
