The Avistar is a great trainer.. All good advise here on the 46 engine
a 40 will work, but the 46 will be a lot better and a bearing 46 can
be used later.. I started with the Avistar/LA 46 For me it worked
out great, not one bit of problems on the LA and the Avistar taught
me a lot.. It even would hover a bit and knife edge somewhat, it
served me well to this day.. Soon to be on floats....MAYBE :-) (PIF)
Just remember to keep the landing speed a little faster than the
normal trainer and it will serve you well!!... Have fun with it!!
