1. How does it fly?
2. Can I fly it fast and not lose the airplane? Need good structural integrity.
3. How is the "fun Factor"
4. What size 2 stroke engine. I have a ST 90.
5. What do I need to look out for?
Flies well
It will comfortably fly as fast as the ST90 will allow it.
Fun Factor is excellent
ST90 will work OK in it (not perfect for 3D but good for most requirements) (I currently have a Saito 1.25 in mine).
Make sure that the braces are on the hoizontal stabiliser properly.
I strengthened my Landing gear block to the fuselage (I do this with most ARFs) with some triangular stock and epoxy.
I discarded the stock pushrods and clevises (I do this with most ARFs) and replaced them with 4-40 threaded rod over which I epoxied some carbon fibre tube.
Start with the recommended CofG - Mine is currently set about 10mm back from that and I find it suit me for fun flying.
