Question:
    Dear Service, I'll ask JR about the MX22 but can you tell me: 1) What is Hold? 2) What is INH which is on the Pitch curve table and the blade angle table? The above two can be found on page 45 of the English instruction booklet that comes with the Raptor 90 3D heli kit. Thanks Jon
Answer:
    Dear Sir, Our technical staffs answered as follows: 1. Hold is "Throttle Hold", which means Autorotation. 2. INH means disable the function or let it at default setting Best regards, Customer Service Thunder Tiger Corp. [ Simon ]
