I have two of the newer VMAR ARF's, the Pilatus PC-9 and the TA6 (JPATS). They are identical in size and makeup. I was pleased with these kits, for the price. Both of them fly very well on a TT .46 Pro engine. I had to replace the clevises on the pushrods, and you are right about the cowl, the fit was less than perfect. I ended up flying the Pilatus without the cowl, primailry becasue it was easier to get to my engine. I fly off of a very rough grass field and so far they have stood up very well. I know of people who have not had such good luck with these planes, but I have to say my experience has not been the same. I would be hesitant to buy the larger of their series of planes without cloder review, but for a throw in the back of the ruck, Sunday flier, I could not beat it for the price.
