Instructions

Print everything at 100%

Brushless Gimbal
To build the brushless gimbal, you need to print gimbal_support.stl file and also all the files included here : http://www.thingiverse.com/thing:898204

You need to buy those things http://www.conrad.fr/ce/fr/product/540033/Rondelle-anti-vibratoire-coloris-noir-A-x-B-x-C-x-D-144-x-48-x-33-x-82-mm-Richco-VG-2/SHOP_AREA_27898 to hold this support with the 5mm tube of the TBS (see the prictures)

You can also print the 2 files brushless_card.stl and brushless_card_top.stl if you need something to hold your brushless controller

Antenna Holder
This mod came in 2 parts, one to hold your VTX vertically (tbs_vtx_antenna_holder.stl) and a base (tbs_vtx_antenna.stl).

You can put a LC Filter (https://www.hobbyking.com/hobbyking/store/__68127__L_C_Power_Filter_1_7A.html) into the base, and cover it (lc_filter_box_top.stl)

As an axis, you can use a 3*20mm screw

Ublox
Finally there's a ublox cover (ublox_gps_cover.stl).
