My opinion is ARF's are now often referred to as kits because commerical kits are going the way of the dinosaur... there's plenty of kits out there just not from the large manufacturers. As such... the work "kit" is losing iits original definition as ARFs are now taking on the kit role. As time goes on many will only know the term ARF discussed as kits and down the road the word kit will come ot mean ARF for the general masses. Of course those of us old enough to remember will know better.. but like WW1 veterans.. once us "kit" builders are gone... thats it ..
