Actually your wrong the new YD85/100 bottom ends is the avenger 85 /phantom 85 same engine case 80cc bottom end is for the old YD100 small bolt pattern on the case where the head mount
@@RaoulDuke224 you might be right but I'm not sure I've seen new cases from flighty company's. I have a phantom, modded phantom with custom head,modded ld100 and ld100,2 yd100s. I just swapped a phantom onto a yd100 plug and play. The only cdh 85 I have looks nothing like a yd with its bogus transfers.
