Thanks J,
Your cub is looking good! have you picked up the windshield material yet?

jstanton

My Feedback: (14)

Yes I picked it up at sig manufacting. They have a 1/4 scale cub kit and you can order the window kit from them. Go to their wed site and look up 1/4 cub and look for additional parts.

Will do, and thanks!

Got the elevators done. Still don't know if I will use one servo or two, so I have not joined them yet. I also modified them for more rudder authority. You can also see the amount of stretch in the plans on the next to last photo. I made another E3 and sandwiched a piece of balsa in between them making a solid 3/8" horn mount.

I finally got my JTEC pitts muffler for the EME-35 I am installing. Here are a few pics of the engine and thought I would add a pics of how I installed the elevator and rudder servo's. I hope they help some.

Steve your build is looking real nice. You are doing wonder work on the horizontal stabilizer.

Thanks J
Your not doing to shabby yourself. Looks like that muffler is a nice fit! And thanks for the link. I'll get one on order. Did you go with dual elevator servos?

jstanton

My Feedback: (14)

Yes I did use dual servos for the elevator and ailerons. My plans are very old and it called for one servo for ailerons using a bell rank system. I did not like that and used dual servos on both.

Steve

I think I'll follow your lead and use dual elevator servos. I'm also going to use dual aileron servos and probably install flaps. I'm modifying the wing to use a 3/4" wing tube as well.

Sounds like you are doing the right thing on your build. The Cub is a very gentle flyer and for that reason I opted not to install flaps. I have flown the 1/5 scale sig cub and it did not have flaps and was a very easy plan to land. It is very stable at slow landing speeds. I would really like to see how you setup your flaps.

Steve

My Feedback: (54)

I'll post lots of pics!! The instructions say that the ailerons can become ineffective under certain conditions, so I'm thinking of using a mix for flaps or full length aileron action. Maybe even a crow function. Still working those things out. I think I read where some one just used full length ailerons as well.

Never seen anyone ever do a full wing aileron on a cub. I would make it role alot better. I am interested in how yours turns out. What are you planning on using as a power plant?

Don't know what happened, but my last post disappeared. Any how, I've got a DLE 30 on the shelf I'm planning on using for this build. Should be a good match!!

jstanton

My Feedback: (14)

Yes that should be plenty of power for this cub

Steve

Agreed!! 😎

Looking good on the fine Steve. I had an idea I wanted to try on the wing struts. I did not like the why the mid wing support was being add to the wing strut and I came up with this idea of trying hinges for a jewelry box. I order some off of Amazon and they came in early today so I was able to give them a try. It looks like they are going to work out well with a little more work. Here are a few pics of my progress with then today. I still have to come up with away to attach them to the wing
