Not sure if you are aware, but they are the same company. CH is a brand of Dragon. Not sure how it works with aircraft, but with armour, the CH brand is either a kit with unusual markings or a little seen variant. Its often a Dragon kit jst with some extra parts or decals. The other CH armour kits are old Dragon ones but with figures thrown in.
Chances are the CH 110 will be a Dragon kit but with something extra. Though saying that, on Hannants there is both a CH and Dragon 32nd 110 and the Dragon kit is selling for quite a bit more than the CH.
