i have two h-9 matt chap caps new in boxes here i have had them for about 3 year i like the planes they are fun to fly i have the h-9 78inch 540 with a moki 2.10 it flys great but i dont like the moki had to get a cline reg for it to make it run right the kangke cap flys good to but the vibration from the gassers are killing them fast
