I own both. I have a slightly modified SE. and a stock top cap arf.
I had my YS 63 on my SE first. Now is on my top cap.
The SE & TC are 2 totally differant airplanes.

The SE is more of a sport flyers airplane. Its billed out to be a fun flyer. Yes it is fun to fly, I have had mine for 2 years. It is not a fun flyer. It will land at a walking pace. The SE will hover but it is hard to Torgue Roll. I have my tail loaded up pretty good, and I still can't get a flat spin (reg. or invert) out of it. It will harrier but is not easy. Also doesn't knife edge very will. I added 1 1/2" the to rudder. I also have a 2" counterbalance on the top. To get a good fun fling SE. You will need to built to kit, not put together the arf, and do a lot of modifications to get it to fly half as good as the TC arf in the 3D department.

My top cap arf will do just about anything in the book. It will land at a crawl. It will knife edge all day long. Hovers real well. Flat spins. I can get about 1 1/2 torgue roll out of it before I lose it. Harriers.

Both of these are good planes. the SE is a great sports planes, the TC is a good fun flyer. Its like compairing a stick to a fazer. Both of them have their good points and bad points.
