PIDS & Battery Selection
The default tuning is for 3S Lipo. If you want to use 4S (14.8v) you will need adjusting the default betaflight tuning. Without tuning betaflight and running on 4S, will cause the motors to run too hot and burn up - voiding the warranty

Why Diatone

Under the DIATONE brand, DIATONE Series GT, the high-performance drone named R (Racing Sport), is also the highest version of the current GT series. The first generation of GTR models, the choice of advice configuration is very rigorous, meanwhile, our strategic partners ( Sun sky, Fury and TBS team) join, will make the overall performance more powerful. The R90/207 uses the common type C-Beams in appearance. When overlooking, C-Beams shows a gradual narrowing shape and feels a slimmer back. The outer side of the camera has two replaceable oval decorative parts, not only seems naughty and lovely but also protect the side panels from damage. Color accessories are also used in C-beams, Motor Mount and prop protection. A variety of colorful combinations that shows yourselves style. R207 small and cute shape is also a good gift.

The GTR90 has an ultra-low gravity design and 2017GT MVS, there was another design breakthrough: FC&ESC Mount (in after referred to as FEM).
FEM is a collection of FC&ESC&TBS UNIFY as one of the design, using the M3/20mm assembling-hole distance without the use of auxiliary tools, TBS can also be installed, compatible with FC and ESC, to achieve the two layer structure, but the total height of only 20mm.

• The installation of electronic devices for mini models is not easy, but FEM makes installation easy.
• The use of advanced laser 3D printing technology, high dimensional accuracy.

The resin material used for 3D printing has the certain elasticity and can reduce vibration when being impacted, and the electronic equipment is not easy to be damaged.

FEM uses the same m3/20mm mount size as the fight controller. It can be installed directly without modification.

Since TBS UNIFY doesn’t have an available fixed position, it can’t be installed by screws, and not allow using glue bonding way in producing or usage mode.
Therefore, we adopt a fixed position design to limit TBS UNIFY movement range. TBS can be fixed after inserting, and no other tools and accessories are needed during the assembling process, so it’s very convenient to install.

FEM applies to the most M3/20mm specifications of FC and ESC, 3D printing screw length of 13mm, most of the two layers of flight controller can be properly installed and the total height of FEM is only 20mm, applicable to any type of model. The resin material used for 3D printing has a certain elasticity and can reduce vibration when being impacted, and the electronic equipment is not easy to be damaged.
