Fuse mount gear
« on: May 08, 2013, 09:21:30 PM »
I am going back and forth on how to mount the fuse gear in my Junar, I'll be using Randy's carbon gear.  Since it will be electric power I don't need to worry about fitting a header/pipe I am leaning toward a plywood plate instead of maple motor mount material.  Is there a benefit to one over the other?

Thanks,

James

Just a piece of plywood with out reinforcement will exit the plane rather quickly. Plywood gear platforms are one of the most common parts damaged. Attaching that plywood to the fuselage and making it stay there takes more work than just gluing it to the sides. I would mount the gear in the wing and make it removable. The Junar is a big plane and it need a strong gear. I am sure you will do a good job so show us some pictures. Billy's Junar was very light at around 55 ounces. I am always amazed at how light his planes are. ~^

The gear in the fuse is  way way stronger than in the wing, you can mount it however you like, but if you use the ply sheet method then epoxy in 2 3/8 square pieces of hard balsa to the fuse side like you would a motor mount, this will serve as an large glue area for your plate.
Be sure to mount the gear in the proper place for good landings, if your careful and drill the mount holes correctly you can turn the gear backwards and frontwards to shift the wheels back and forth for grass or hard surface landings/takeoffs

I'll try and post some pics when I get farther along.  Progress is slow because I can work only a few minutes at a time while recovering from knee surgery.  I'm trying to hit about 60-62 ounces ready to fly (it's an electric power plant).

I decided to go with the maple blocks, should have it knocked out today.
