The 'What did you do in your workshop tonight?' thread

[Snoopy1]

I hate to break it to you guys, but we went to the dark side the first time we picked up a transmitter. It's all wicked!!! It's all like a drug and we can't wait until our next fix.

Have to agree with you but I have never had this much with anything else. And I can do it for hours. And keep on enjoying it. So I guess just leave me there.

Hi “Balsabust” thanks for the reply. I am not home right now. You are welcome to a copy of the cad drawing of the motor. It is copy or should say the exact out line of a DA50. Spent a couple of days measuring it and then making the drawings of it. Makes life a little easier when drawing up something new.
Thanks for the input.
1. I started laying it out in foam because I have vacuum bag equipment and have some foam cutting wire. But after laying it out and adding in all the supports it just did not look good and really I was starting to add more weight than I would like so scraped it and started on a wood frame.
2. Will look into lining up everything and see if my wood frame still fits and all the hard points still work. Will let know.
3. Made the fuselage 90 % of the wing span.
4. Will extend the nose closer to the propeller or 1/4 from the propeller.
5. Question on a 50cc profile with a gas engine how thick did you make the stabilizer. My stabilizer will be glued into place.
6. One more important question is fuselage to CG ratio. What I mean if you measure the length from the back plate of the spinner to hinge line of the rudder, and then the length from the back plate of the spinner to the Cg. The Cg measurement should be about 27 to 31 %. Of the spinner to the rudder hinge line measurement. I hope you get what I am asking. I checked the PDF you sent and it was 29%.
I will get a picture of the wood fuselage soon and let you see it. Still needs a lot of work and numerous changes till I get to where I think it will work and not twist as much as the first one I drew. I am also having trouble getting the landing gear fit and not weight a ton. Went from flat aluminum gear to piano wire it is lighter and easier to lock into fuselage. Does not look as good but I believe functional. The is being built to teach me to 3D. When I am half decent at it I will get my Viper ST into the air.

Ok I still haven’t made it to my shop to get measurements yet but to be honest when we designed the 55cc edge and even the smaller versions and my Giles it was all just going off of what looked appealing to me and my buddy as we did things. As for the tail surfaces it’s all 1/2” thick. Fuse itself is 7/8” foam sheeted with 1/16” balsa making it 1” thick. For the vertical stab you need to not only glue it onto the fuse it needs to be pinned as well. A buddy had his keep coming loose. On my edge it has two 1/4” dowels going about an inch into the fuse. Now my advice for the horizontal stab is what I did with mine. I went overboard and put a carbon tube in it full length which I don’t think it needs but what I feel it does need is that I framed it out of 3/8” square sticks and then sheeted both sides in 1/16” balsa. There is no way it will ever break in the air. The elevator itself is just 1/2” balsa sticks but what you would consider the spar on it is a balsa carbon sammich in that its a piece of 1/8” balsa, layer of carbon tow, 1/4” balsa, layer of carbon tow, and one last 1/8” balsa pieces. Hope that makes sense. I can post pictures later when I pull them off my thumb drive.

Unboxed a wall mounted shop vac. Had to find something better and I like this.

I belive I understand all that you have explained. And the horizontal stabilizer has been drawn up at 1/2 thick so we are on the same page. I am not quite up to speed how the elevator is done. The stabilizer has been drawn up with a 1/4 diameter carbon tube in it. What I will do is tomorrow take a picture of the horizontal stabilizer and post it so you can see it have not started the vertical stabilizer and rudder.

You guys make it back home yet Bro? I bet grandmas and grandpas were waiting on pins and needles these last few weeks to meet their new grand-daughter!

Yup I guess I had not given an update. we got home on Tuesday morning. Grandparents where very excited to meet this little lady. she turned one month today and had a Dr appointment. Went well, they are happy with where she is at and is up to 20" long and 7 pounds 11 ounces which is almost two pounds over her birth weight.

Hopefully this helps some. One pic of the stab before I sheeted it. I used a 3/8" tube in it. Second pic is the spar sammich I was referring to. the final pic is where that piece is located. It made the elevator really strong.

All you guys have a bud influence on me was looking at the plane that the Stang just bought it looks pretty good and seems to do 3D pretty good. And looked at a few videos on it and it seems to fly outdoors very well. Just have get all the details of what it takes to get it into the air. Motor, Esc and servo numbers. O’ boy going to the dark side.

So the power package I am using for the Twisted Hobbies Edge is the package from the DW 330 foamy. When I went to Washington last year to pick up the new Behemoth Yak (2), Steve had the foamy 330 on the shelf and he basically gave it to me ready to fly, minus servos and batteries. The motor is a Turnigy 3632-1200. About 22 bucks from Hobby King. The ESC? I have no clue but Steve don't do anything questionable so I am sure it is a 45amp if I remember right. Again, probably only about 20 bucks. The Servos, (4) are all Tower Pro 85's. The Edge actually calls for a little "beefier" servo, but I am pretty sure if they can handle the 48" 330 with no problems, they will be able to handle the 43" Edge. I think the servos are about 8 bucks at most each. I believe the batteries I purchased were around 39.00 for two 3s 2200mah Lipos. So basically, for around 120.00, you can get everything you need for the plane. The plane was the expensive part. 178.00 with shipping. But heck, I think I can have a lot of fun with that 300 dollars worth of electrified foam. LOL.

I got it now thanks for that still working on the cad drawings it is take a lot longer than I thought it would but I am really enjoying it. It has been many years since I made a drawing. Moved out of the design office in 1989. Still do design work and review drawings but did not do drawings.

Just sat in the shop and pondered the sweet Sig clipped wing. Then BAM! It hit me..... That baby going to need a four stroke for some awesomeness sounding fun time.... This NGH GF-30 will swing the same prop I have and I can make an exhaust for it to dump in the scale location. Giggity

Yup flying buddy has a sig 1/4 scale clipped wing cub. Flys it on a OS 1.20 four stroke. very scale like and sounds so cool flying by.
