Summary

This is antenna and GPS mount for Mark4 frame. Note that the distance between tail frame legs seems may be different from one frame size to another, but if the model is printed with TPU filament, 1mm different is easily compensated by flexibility of the model.

GPS mount bed is fitted for BE-252Q (25×25×8mm). For other GPS sizes please drop me a message and I will make a custom model for you.

There are models for 20° and 25° antenna + GPS inclinations.

If you use JHEMCU 2.5W VTX or RushFPV Solo Tank (35-37 mm length), you would need a model with longer antenna tube ("long" suffix). If you use SpeedyBee VTX (28 mm length), you would need a model with shorter antenna tube ("short" suffix).

The length of antenna tube modelled to fit RushFPV Cherry 5.8G RHCP MMCX 155mm antenna.

Assembly:

First put a heat shrink tube on cable, then insert antenna into the top part of tube and lay the cable into canal.
Mount the holder on tail frame legs.
If necessary adjust the length of remaining part of the cable by checking the distance to antenna socket on VTX.
Apply some glue on the top and fit the shrink tube with a heat gun.

Notes:
If you have a properly tunes printer which can print small bridges, then no supports are needed. Otherwise bottom side will not look perfect, but I personally don't care....

Mind the speed and cooling when antenna tube is printed. I was printing with 10 mm/s speed and 50% fan for top part.
