Laughing@half a pound = $77.

Count me among those who built his UCD 46 stock right out of the box. I did make one modification though, I used a Sullivan tail wheel assembly because I like it. I think Great Planes put that little piece of plywood in the tail just for me to mount my Sullivan tail wheel.

After many flights I have yet to find a reason to replace any of the hardware provided.

I used no reversing Y-harness because my Futaba radio provides for using two elevator servos.

All my servos are standard Futaba S3004 that came with the flight pack I bought. There is no need to use heavy powerful expensive servos since this is a slow flying light weight plane. I guess I got off cheap.

MY UCD 46 is powered by a Saito 72 and the CG is in the correct location.

We don't all choose the planes we want to build for the exact same reasons everybody else does. There are many things to consider in our choices. Thats probably why there are more choices out there than Fun 50's and UCD's. But, it does appear that the UCD is hugely successful in spite of its faults.

I wonder if the guys who fly giant scale 3d aerobatics would listen to us if we told them they could fly great 3D with a smaller, less expensive engine?
