Allan's Scale SHK glider project - In the workshop I have been building my first ever scale glider from scratch. It is a 5 meter SHK using my own plan and build techniques. To see it on my build log Click here. It is a long process and I expect it will take about 9 months of mostly composite construction. I'm about 3 months in at this stage and have tail built and most of the fuselage. Foam cores for the wings are cut too and design finalized. I have done my best to make it an efficient thermal flier. It will be light and stiff with a carbon fibre wing using an aerofoil designed for the model. The wing has been tweaked to improve handling and it should be a super flier. Here's hoping anyway.
I really like this machine. Its Vee tail gives it a unique character.

A little more done last night. It feels like I'm walking in quick sand at the moment. There just seems like there are more and more jobs to do. I have never built a instrument panel before but many have so there is plenty of advice out there. Clubmate Carl had Dave Platt's videos and Fishbed came up with the instrument graphics from an old copy of Silent Flight, now there was a great magazine. The panel is in 3 layers as you can see and the bezels made from hand cut rings of pipe. This let me get that 3D look. The hands are cut from a white plastic container lid. They have good depth too. The glass is just thin clear binder cover plastic sandwiched in place. Knobs for the vario and Altimeter are Allen screws with the hex filled. This lot was about 3 hours work. Oh, and I know it looks a bit wierd, but I fitted a $5.00 ball compass from the $3.00 shop (how does that work??). I figure if I ever get to do in cockpit video then it would be fun to see a working compass.

SHK Pilot and interior SHK Pilot and interior and canopy

I have been working around the front end this weekend. It was time to try and make a pilot. I've never done this before and frankly lack the talent of guys like Mitja. Doug's cheap Hobby King head has been wrenched off then mounted on top a 10 gram servo. This will be y leaded into the rudder channel(which in a Vee tail works as elevator as well). Next I started carving foam for a little guy who would fit the seat. He is about right for the scale. I needed hands so took Mitja's (see build log)lead and bought some Scalpey and had a go at sculpting some hands. They are a bit chuncky and would look better on a Cabbage Patch doll I suspect. The material is beautiful to work with and when you are done you just put it in the oven and out come these flesh coloured hands. My wife decided a fine looking chap like this would be married and donated a ring to the cause. Its baked on so he will never get it off. He came out OK I feel for an amature effort and his cloths will cover a wealth of errors. All this toy making feels a bit odd but it is fun. Next up I trimmed out the cockpit with grey vinyl and there are still the closeouts to add either side of the seat back. Looks good though. The other big job was the landing gear. It now has mounts, and big servo. I have made some half frames to bolt it too and cut and hinged the doors then set the whole assembly in place and expoxied in the frames. The gear unbolts easily for removal and repair. I'll go back and finish the tail end then install the gear in the fornt end. After that prime up the fuse and start on the big carbon wing.

Carl's Lockheed Ventura Bomber. The model Ventura to my own design and is is 1/12 th scale giving 65 1/2 inch wingspan 1665mm. Consruction is conventional balsa and plywood. The wing is fully sheeted and covered with tissue and Dope. The Fuselage has Balsa sheet sides and planked Balsa top and bottom skins over Balsa and ply frames and covered in Glass Fibre cloth and Epoxy resin. The cowls and engine nacelles are shrink moulded drink bottles. The cockpit canopy, gun turrets and astrodome are vacuum formed plastic. The gun barrels are from plastic tubes from cotton buds, the barrels perforated outer cooling tubes are from drinking straws. Ammunition in the top gun turret are the ends of toothpicks woven with cotton as the belt. Electric powered with Brushless motors and LiPo Batteries. It has pneumatic retracts for Main Landing gear, and home made mechanical retract tailwheel ( with cable steering and automatic centering when it retracts) Flying weight is be about 3.7kg. The colour scheme represents aircraft of RNZAF 2 Squadron, late 1944 and 1945 as they operated from Green Island in the Pacific. It flies well but is prone to wing tip stalling, the wings are very tapered with a very short wing tip Chord.
