Condor 69 (oz8560)
About this Plan
Condor. 72inch wingspan thermal soarer for single channel RC.
Quote: "A single channel R/C thermal soarer. Condor 69, by TJ King
CONDOR was designed and built in March 69 with the aim of producing a model which while being light in weight would penetrate a stiff breeze. This I have, I think, achieved in the Condor 69. It has been flown consistently last summer with many flights of up to 10 minutes to its credit. Once you have launched Condor, it may only be a flight of 4 minutes, but if lift is found, then watch it soar for 10 minutes or more, depending on your ability to keep it in lift.
Construction of fuselage: Commence the fuselage by building the 3/16 in x 3/16 spruce sides. When dry, cement to 3/32 sheet sides. Then add ply formers starting with F4, F5 and F6. After fitting formers plank top and bottom with 3/32 sheet, but before doing this place the torque rod in position also the spruce tow hook support between formers F4 and F5. Now cement all remaining balsa blocks and pine nose block and shape them as required.
Note: Wing fairing block is shaped on fuselage then detached and fitted to wing. The rest of fuselage fittings are mentioned on plan. The detachable canopy is constructed with ply formers F2A, F2B and 3A, with 3/16 x 3/16 keepers at each end.
Construction of wing: Start by pinning down S2, do not forget to place packing under this main spar. Next pin down the trailing edge, and place the ply ribs W1 in position. Slide in rear Aluminium tube, then add ply ribs W1A and slide in front tube, do not cement tubes at this stage. Now add remaining W2 ribs, leading edge and rear spruce spar. When dry, cut through trailing edge, rear spar main spare S2 and leading edge where indicated. Divide centre section into three parts - two outer panels and a centre. Slide outer panels from tubes, remove aluminium tubes from centre, cut and Araldlite back in shown positions in centre and outer panels. Leave centre sections at this stage..."

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.
