After building up the full fuse F-16 mid-pusher jet, I came up with another project and this time is the Yakovlev model. It is a 30" wingspan with KFM2 for the wing sandwich with wooden spar, powered by 2200kv Turnigy, 6x4 prop, 1800mah Lipo with 30A ESC. I love the design of the plane and the large wing area suits with my design intention that is to have a mid-pusher depron park flyer jet.
Starting out the design using sketchup and off to the cutting out plan. Laying out each pices on the depron sheet within a couple of hours and all seem pretty much fun and less time consuming. I'm using a total of 2 sheet depron for this project.
The design of the plane parts are a mixture of slotted and tab style method. Mixing them both seem an easy alternative for me and it speed my build process.
Joining the bottom plate and side duct using the slotted method.
Front nose assembly is using tabbing method.
For the finishing, I'm using an acrylic spray paint can and a bit of colored opp tape for the cockpit.

Cockpit area is large enough to be fit in with lipo batt. Easier access for your electronics too.
A large number of images in my build log can be view in rcgroups where a details explaination were stated in my post. You can check it out here: http://www.rcgroups.com/forums/showthread.php?t=2729215

Conclusion:
It is indeed an easy build with this one and you can get on flying with no time. I flew it using 2200kv motor and for the first maiden, the plane does not have enough thrust to climb. Changed it to 1500mah lipo then only it start to flew well. For the colouring, be sure you didn't end up like me where the opp tape eat the color away. This has led me to loose my elevator and aileron during the control horn assembly. You should finish everything first including the control horn assembly, servo placement, wires, and hinges before you give it a color spray. Another words of caution, be sure to bevel the KFM2 nicely to make it less drag and in same time improve the lift.
