To be clear, whilst I haven’t any to test, I believe that this problem does not apply to the M-Link MPX receivers. It only affects the ‘light’ version of the rx-7 in my direct experience but I would be wary of any of the ‘light’, ‘white’ receivers if I got any.

Curiosity got the better of me and I voided the guarantee by opening the older silver (S) and newer white (W) receivers that I tested. I'd say they were very different which maybe explains the performance reduction I measured

It's time to place the servo trays, which are printed in ASA. Those are for planned KST X01 mini, but fits the 135 too. There is a left and a right one. They are placed towards the inner side, taking care of the rod exit side. To fix them medium cyano and activator does the gluing job very well. Probably I won't use the upper part of the trays. A hole has to be cut to let servo wire come out. A line is traced parallel to ribs and reported to the outside of the sheet, to have the exact rod exit point. Then the exact position of the servo trays is traced outside the bottom sheet, to find it easily when the wing is closed. Servo wire is placed for future use. Please remember: - servo trays are left and right and should go in the right place - sign the bottom sheets as left and right, otherwise the drawing get lost inside - fix the wires! Inserting them in a closed wing could be time consuming
