RE: Walkera 60B issues
I have an elf hobby 4200kv and esc and for the money I think it's done very well, 1000s of flights and it's got loads power, it hovers at 45% throttle,
as for the servos it's not the easiest thing to do, pro towers are the best that fit and are quite cheap but aren't the best, but if you can make new servo mounts hitec hs65mg are well worth the trouble, metel gear survives many crashs, saves you money in the long term
