That's an Easy Fly 40 from Hangar 9 - you can download the manual from their web site.  I had one as my primary trainer and fall back airplane for years.  Can't tell you how many times I crashed, er hard landed  that thing and kept putting her back together.

I used Orange cleaner on her for the covering but eventually replaced the Ultracote covering with Monokote.  And K2R works wonders for inside cleaning - soaks up fuel and vacumes well.
