Slipping the Pushpak
Gosh it's been a while, but I do have 200+ hours in the Pushpak and haven't flown one for 3 years, the biggest problem that one encounters whilst side-slipping is running out of aileron authority before rudder. It is also quite easy to port (draw only air) the rear tank if sideslipping to the right whilst drawing fuel from this tank. Conveniently neither of these are mentioned in the handling notes but the latter is obvious once one follows the fuel lines - the spluttering engine does tend to grab one's attention!
Hope that this helps,
