I have had 3 Kougars & 3 Kavaliers , all flown extensively. The Kavalier is one of the finest #2 planes you could hope to find. very smooth, gentle stall.only a bit harder than the kadet or Eagle II. do not eliminate the washout.you should use something more powerful than a FP or LA type mill but a .46 engine is not neccesary. SIG designs are usually winners and this one is no exception. stay away from the Kougar untill you have at least one low wing under your belt.the foam wing can be built as light as balsa with the use of double -sided tape to attach wing skins . saves much weight.used to be sold by Wing Mfg. go with the wing bolts but I cant agree on the canopy as it is well designed compared to the old Goldberg falcon. and I think it looks great.I saw one of these years ago made up, kit bashed, as a counter insurgency fighter(COIN) really neat.
