RE: Bi-plane as second plane?
I have heard the Sig hog bipe flies great...
I would say the question for you is can you put a plane right where you want it on landing? Level wings..and a nice gentle flare at the end? Thats what floaty bipes like ......precise landings......... take off rolls can be tricky, I avoid hard surfaces,when grass is available.
If you like to build and rebuild you are definitely ready !
The real key to success though is keeping it flying slow and level at landing, but no stalls of course !
