RE: CMP 120 size Cub - Assembly
It's typical china ARF construction. China lite ply and laser cut parts. I have an older version, so the paint on my cowl and wind screen don't match the china cote covering.
The airframe seams reasonably well built. The landing gear is kinda cool, but you'll want to replace the stock rubber bands with something much more substantial. Right now I have (6) #64 rubber bands on each leg and it seams to be holding up okay. But I have not attached the wing and fully assembled the plane yet. Once the thing is completely assembled I'll have to see how it holds up. Might be okay with just 6 rubber bands - might need 8 on each side.
The cowl doesn't have a lot of inlet opening to cool your engine. I'm using a DLE20 gasoline engine. I want it cool. It's brand new. I decided to build a baffle inside the cowl to direct as much air over the cooling fins as possible. I'm going to install the plastic dummy cylinders and cut a hole in the forward facing side of each cylinder set. That would effectively TRIPLE the square inches of inlet opening. I'm also going to build a small lip on the bottom of my cowl - near the outlet opening. That will help suck the air through the cowl.
I'm planning to buy the DuBro 1/3 scale Cub wheels from Tower. At 5.6" diameter, they would be almost the perfect size bush tires for this Cub.
The stock tail wheel sucks. It REALLY sucks. I replaced it with a great planes scale tailwheel. I cut a piece of 1/4" hard aircraft plywood to fit the bottom of the fuse - last 4 or 5 inches of the tail on the bottom of the fuse. I drilled the holes and mounted blind nuts for the GP scale tail wheel. Mounted the bracket and then cut some covering off the bottom of the plane. Glued it on with a paste of 15min epoxy and micro balloons.
I got it for $100, but it was missing some hardware. I can live with it for $100.
Would rather have had the World Models 1/4 scale Cub. Thats what this was SUPPOSED to be when a friend went and picked it up. But it wasn't a World Models Cub and it ain't 1/4 scale. I almost didn't buy it. But it was still a decent deal for $100 and I just happen to have a shiny new DLE20 sitting here......
