Question for you fella's what do you think the difficulty of combining 2 citation kits together to make a ultra/V or some of the larger citations? I dont have any info if you would have to increase the iwing area or not so any info would help I have a old hasegawa citation that I got off ebay and noe that revell is re-releasing the kit if it possible it might make into an easy conversion, thanks erick
