Sigh Posted October 20, 2013 Author Share Posted October 20, 2013 Sorry for the break gents. The right wing is built right. The landin gear block seems more reliable. The planking is ok. I have a problem about bending wires. Either i have them bended somewhere else or I'll try to find a wire bender. While i glue and wait for the glue to dry. I carved the headrest i have uploaded the photos to my album but from my phone it is not possible to post them to the thread. I'll do it tomorrow. Good night.

Sigh Posted October 21, 2013 Author Share Posted October 21, 2013 I laminated three half inch balsa blocks. i had put them on top of each other so that i can understand how deep i carved also that way the walls are stronger because of the glue. i saw this when i was searching the internet for other building threads. The plastic headrest weigh 13 grams, the uncarved block weigh 36 grams. it may be around 20 grams now.

Martyn K Posted October 22, 2013 Share Posted October 22, 2013 Nice and tidy workplace. That wing sheeting is very neat as well - a very nice job. Martyn Quote Link to comment Share on other sites More sharing options...
Sigh Posted October 22, 2013 Author Share Posted October 22, 2013 thanks Martyn I am trying to keep it tidy it is hard to stop working early to tidy up. by the way I was reading posts I found that I forgot to add a photo of the dihedral brace pocket. I hope this will push the plywood to the spar for a better contact while gluing. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted October 22, 2013 Share Posted October 22, 2013 Hi Sigh, for fun I installed a child's model plastic pig in the cabin, after all the plane is an Astro hog. Caused a laugh at the flying field. Cheers Quote Link to comment Share on other sites More sharing options...
Sigh Posted October 23, 2013 Author Share Posted October 23, 2013 i'll check the toys at home, once i took some small animals but i think i didn't have pigs among them. it may be really funny and maybe lighter too. But you know what? I think a few people will know this plane. Even if they know they wouldn't know the correlation with a pig pilot. what i know i will have a very comfortable headrest for the lucky pilot. OK not so lucky. The only control in the cockpit is the receiver on/off switch which i'll advise him not to touch. yesterday i glued the leading edge cap of the right wing. This evening i may remove the pins and sand it. Today i am going to receive the covering materials. I think there haven't been much interest to the build maybe i should be building something unique. or building with new techniques. or maybe my English makes it hard to read. I was expecting much more social interaction. but anyway as long as the thread shows up in web searches and help others to build it is fine.

David Davis Posted October 23, 2013 Share Posted October 23, 2013 You're doing fine Sigh. Most of us are jealous of the quality of your workmanship! Quote Link to comment Share on other sites More sharing options...
Sigh Posted October 23, 2013 Author Share Posted October 23, 2013 thank you but; I didn't say that because i expected compliments. i am here to exchange just about anything. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted October 23, 2013 Share Posted October 23, 2013 I second David. Fine work I must say. The Astro Hog is a classic. On another flying forum it was reported as being the "best flier of all time". Must agree with that one, mine flew like a dream, with peachy landings. Run out of wood at the time, so I built the pilots head rest from bue foam and painted it. I think he liked it. LoL. Mine was not a kit, but built from Boddos plan. I too reduced the dihedral for easier aeros. Cheers. Edited By fly boy3 on 23/10/2013 20:43:01 Quote Link to comment Share on other sites More sharing options...
Sigh Posted October 24, 2013 Author Share Posted October 24, 2013 Do you have a photo of your hog flyboy, I also wanted to see the pilot Quote Link to comment Share on other sites More sharing options...
Sigh Posted October 25, 2013 Author Share Posted October 25, 2013 The wings are almost finished. I'll give a break for a week and start building the fuse when I am back. 28th is our wedding anniversary, we are going on a vacation to the south coast of Turkey. The weather may be nice enough to swim there. Quote Link to comment Share on other sites More sharing options...
Sigh Posted October 29, 2013 Author Share Posted October 29, 2013 I am back. We enjoyed our vacation very much. I have a youtube link of paragliding. I don't know if it will work from here https://www.youtube.com/watch?v=IzVjlp7Kc3c&feature=youtube_gdata_player Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted October 29, 2013 Share Posted October 29, 2013 Hi Sigh, glad you enjoyed your break. Sorry never got round to take some pics of my Hog, but I can tell you its a wonderful flier. Sold it to a complete novice to use as a trainer, and that was before buddy leads etc. You can buy a packet of children's plastic animals ( cheap as chips) on Ebay, including the pig LoL.

Sigh Posted November 4, 2013 Author Share Posted November 4, 2013 so i started the fuse. i am planning to install a hardwood piece to be able to install a landing gear. if i have trouble with bending the wires and using the wing mounted landing gear. I have two 12 oz tanks one is slant style and the other is more conventional where you run its neck from the firewall. yesterday i laminated the firewall parts. started to plan my engine and tank installation. the manual of the engine suggests to have the carb center line and tank center line to be level. the SIG plan asks to mount the tank neck half an inch above the thrust line. unfortunately this is not even close to the engine manual. i have to select one method. by the way this sis the first time i am mounting an engine and tank to a plane. I'll check the other forums for that specific problem. Quote Link to comment Share on other sites More sharing options...
Martyn K Posted November 4, 2013 Share Posted November 4, 2013 Can you photograph your planned engine tank layout on top of the plan and let us see what the problem is? Martyn Quote Link to comment Share on other sites More sharing options...
Sigh Posted November 11, 2013 Author Share Posted November 11, 2013 here is the firewall with the important lines on it. the engine manual at the background instructs the fuel tank installation. the astro hog manual requires the tank center line half an inch above the thrust line. so it contradicts with the engine manual. but it is actually too late to discuss this because i without writing here and waiting for an answer decided to do what the astro hog manual instructs because the carb. barrel center line is too high; some part of the tank would be outside the fuselage if i insist on the engine manual instructions. here is the fuel tank i will be using.

Martyn K Posted November 11, 2013 Share Posted November 11, 2013 Sigh You will need to offset the engine mount to the left to allow for the right thrust - keeps the thrustline down the centre of the model. Martyn Quote Link to comment Share on other sites More sharing options...
Braddock, VC Posted November 11, 2013 Share Posted November 11, 2013 Sigh, 3 things you can do :- 1. install the tank as best you can, if there are problems go to point 2. 2. install a header tank between the main tank and the engine so its centre line is in the right place. You still connect the exhaust pressure line to the main tank and you can pick up header tanks from heli specialists (not electric helis btw) it should come with instructions. or 3. Mount the engine inverted and install the tank to suit. Personally i'd go with 1. This is one of the reasons why engines were mounted sidewinder from the year dot but that would not suit the hog.

Braddock, VC Posted November 11, 2013 Share Posted November 11, 2013 Take a look at that picture of the orange hog with the saito with unusual plumbing, try figure out where the throttle barrel is relative to the tank centre line, bearing in mind 4 strokes can be more intolerant of tank position (unless they are lasers).

Sigh Posted November 11, 2013 Author Share Posted November 11, 2013 I actually hoped the plans covered the right thrust and down thrust. sorry to hear that. Braddock i did what the manual asked for but i am going to install the tank as high as possible. to stay close to the engine instructions. thousands of hogs flying without hopper tanks but i have seen a couple of hogs with side mounted engines. now i know why Quote Link to comment Share on other sites More sharing options...
Sigh Posted November 11, 2013 Author Share Posted November 11, 2013 ohh that orange hog was from Singapore; the guy after flying it for a few flights or maybe after the maiden sold it. i hope not because of any problems. but without copying it i ended up very similar with that guy. i checked today his photos.

Braddock, VC Posted November 11, 2013 Share Posted November 11, 2013 Personally I wouldn't worry, chances are there won't be a problem. What might happen as the plane and engine installation age is the cumulative effect of small issues creating fuel feed problems. Quote Link to comment Share on other sites More sharing options...
Sigh Posted November 11, 2013 Author Share Posted November 11, 2013 how should i adjust the correct thrust. the firewall is glued to one of the sides. as far as i know it should have a little bit of right and down trust. i am not sure if i can measure any small angles but i can roughly adjust by just looking. the formers Quote Link to comment Share on other sites More sharing options...
Sigh Posted November 14, 2013 Author Share Posted November 14, 2013 i joined the fuse sides, haven't installed the aft most formers but the rest of the formers are in place. i glued some scrap balsa on the snake exits. i had cut a poplar ply wood block for the main landing gear drilled and installed blind nuts. i trial fitted the engine. and fuel tank.
