My friend just put the first flights on his thie weekend and it looks great. A very foregiving airplane, he just soloed 3 weeks ago wnd this is his third plane (ugly stick trainer and a World T-34)
The Sukhoi has a Saito 180 in it and a beautiful glass cowl and all the louvers are functional.
Keep in mind, if you put a pilot in it it must be semi reclined not sitting straight up.
