I added the Turtle deck and I also started covering a few of the tail pieces. The Turtle deck is 0.6mm ply wood formed over two balsa fuse formers and stuck down with super glue.

I first had to do a final sanding with 220 sand paper before applying the covering film. This is my very first attempt at covering and I have to say I am happy with the outcome. I decided on a Yellow, Black and White color scheme.

Thank you tecotecovoador. I had to use a online dictionary to translate some of your words

I have covered the rest of the tail pieces and I have also added a 3mm balsa platform which will add additional stability when attaching the horizontal stabilizer. The vertical balsa strip that is attached to the trailing edge of the vertical stabilizer will be trimmed to the correct length and sanded to the correct width when it has been fitted to the fuse.

The only thing I have done was to sand down all my wing surfaces again. Needs to be super smooth before I start covering. Apart from that I have not done anything else. Work getting in the way at the moment. Working 12 - 14 hour days so I do not have the energy to do anything else right now. I am hoping to get cracking on this project again in a few weeks time.

The ultimate bipe looks great. Since it looks great it should fly great too! I never got around to building one. Glad to see one be built!

OK so things are quieting down a little on the work front although the studies are still keeping me pretty busy. I went to my LHS today and purchased the servo's for my bottom wing. I went with the JR NES-591 servos. The torque rating on these servos are 5.11kg-cm. I am installing one servo in each side of the bottom wing. The servos will be driving the top wing aileron and bottom wing aileron for each respective side. I also purchased another roll of covering film.

From Monday evening I will start working on installing the servo's and completing the bottom and top wing construction as well as the covering.

The servos are a little too big to fit into the wing. Not a train smash though as I was planning on using the same servos for the elevator and rudder so I'll go in search for smaller servos for the bottom wing and use the current servos for the Elevator and Rudder. I continued on the balsa sheeting on the top wing and also started work on the Turtle decks. I used 3 separate pieces of ply to create the turtle decks as the shape of the fuse requires different angles to be cut to make it fit. I found this to be easier than using one piece of plywood.

I filled in all little gaps and discrepancies with One strike filler. I know it seems like excessive filling but 90% of the filling you see will be sanding off. I also used filling on the edges of the turtle decks since the cutting the edges of the ply against the grain caused the ply to splinter and chip off in certain places. The filling will smooth out these gaps nicely. I only finished work at 01:00 this morning so I didn't have time to sand it down. Will definitely do that tonight and post more photos.

I sanded down the turtle decks I filled yesterday. I also installed the tail servos. I used the 6mm spruce bars that I used for the wing spars to mount the servos. I drilled holes in each end of the spruce bars and fitted them by using 3mm self tapping screws.

I started stripping the covering film from the horizontal stab in preparation for fitting. I'll start work on the cowl next.

I have decided to build my own cowl. My idea is to do the basic construction for the cowl and then to thicken the outer walls with balsa sheets. From this I will have a thicker wall of balsa to shape the cowl so that it looks the way it should. I mark the shape of the cut outs that I want to do and then make sure that the balsa sheets that I used to pad the cowl is thick enough for the part I am about to shape. I will mark the general shape and size I want for all sides of the cowl and then cut the rough shape. The initial shaping is done with a Dremel tool with a sanding bit. The final shaping will be done by hand sanding.

I'll start with the sanding process tomorrow evening and post more photo's.

The cowl is nearing completion. I am done padding the inside of the cowl and most of the shaping has been done. Cowl was padded on the inside using 2.5 and 5mm balsa and layered using super glue and epoxy in places. I used filler to smooth out a few rough patches and also to assist with some shaping. I am currently waiting for the filler to dry. After final shaping and sanding I will cut the air vents in the cowl nose.

I sanded the cowl down using grit 100 sanding paper and then smoothed it over with grit 220 sanding paper. I cut the air vents in the nose of the cowl. I know this shape and style isn't anything like the real Ultimate cowl but I like to improvise as I go along

Next step will be to clean out the excessive balsa layers in side the cowl.

I started removing the excess balsa layering on the inside of the cowl. Not done yet but removed most of it. I also cut the bottom wing ailerons to size and beveled the leading edge of the ailerons. I did the beveling with a hobby knife and smoothed it over with 220 grit sand paper.
