sportsman aviation arfs were the worst arfs i've had. i bought 3 of them before i learned my lesson. crappy covering jobs and poor glue joints. but these were the lower end arfs. i've been told that their higher end arfs are much better quaility. they are being sold under the hobby people name now along with modeltech. i recently bought a modeltech suhkoi 29 which is fair. better covering job than sportsman aviation arfs.
the best arfs i have had are great planes, sig and goldberg in that order.
