RE: 25 size bipe
I would say that the 30 size is still available in Taiwan but not as popular as well. The good thing is that many trainers are sold in the 30 size so that there is still some market for 30 size second and third planes. Yesterday in my LHS I was tempted to buy a Patriot replica in 30 size or a Kyosho Aurum 30. But because my 32SX is currently installed in my TT Lazy Tiger, which despite all my complaints, I love... I purchased a Funtana 40 for my homeless FZ63. Price? US$120 including a aluminum backed spinner. NICE.
Now I've got to get crackin' at making it! It's my 6th ARF kit sitting on the shelf! I'm still debating a VQ P-51. I love to build... but addicted to buying!!!
