Kyosho MR-03 2.0 Mini-Z Unit Set (RA38)

One thing I don't like is when either instruction manual doesn't show info on a specific item here is an example "How come the box packaging shows that the mini-Z is compatible with gyro unit MZW446 " but find out last minute there is a note stating that if you purchase this R/C receiver Unit set 2.0 MZ414B, you will have to get the MZW446 to have the 2.0 ver to work so NO one states this Not even the owner's manuals so I will get it but I feel so cheated out the unit that I have will not work with gyro 2.0 MZW446 it needs the other one Gyro unit MZW431 since it has a 4pin connector just like MZW446 it has to match if only the owner manual stated this I would have been ready to get stuff and like I said it's good but sad and I feel cheated out what is worst no original gyro for the original R/C unit which is MZ414 when you first purchase the RTR kit all info points wrong or misleading on the packaging hoping that the gyro will work it will not until I get MZ414B receiver unit, so why would u buy as an option if I just tested it, it will not work MZW446 unless u have upgraded to the receiver unit MZ414B which works with MZW446 and both units states gyro 2.0 and receiver unit MZ414B 2.0
