Stay Tuned for upcoming how-to videos for this and all new Diatone Products.
Grayson Hobby has custom soldered  XM+ (FRSKY) receiver. We even go that extra mile and - FLASH - the FrSky receiver with the latest firmware before we solder up the quad so you can enable RSSI on your OSD. We feel this is extremely important, thats why we go the extra mile and flash each receiver before we solder up the quad

What is RSSI? Simplified, it will display your receiver strength in your OSD keeping 'fail safes' to a minimum. 

Please note final receiver installation will be required before flying. Everything is soldered, however, the receiver needs to be mount and the antennas need to be secured in a manner not to fall into the path of the props.

    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.

    Almost Perfect! Review by Jason C Herweg
    Pros: This is an excellent micro quad! Its typical of the high quality product Diatone has been producing lately...
    The new V2.1 addresses almost every issue from the previous versions. The new upgraded 4in1 esc is excellent, with smooth throttle resolution; plus, the on board current sensor is much better. The new 8K gyro FC was an obvious improvement.( Not really sure why they ever tried a 32K gyro on a micro to begin with). The added filter capacitor definitely helps to clean up the FPV feed... Thanks to Grayson Hobby for offering the V2.1!
    Default tune and filters is adequate for 3S. Definitely "flyable" out of the box, so to speak... I re-tuned, and tested for 4S as well. Although its possible to run this quad on 4S, I would recommend you keep it 3S. 4S works as advertised, but the packs are just too heavy, and they effect flight performance. You will have a better experience with 3S...
    Cons: The flight stack bolts were a very thin M2 nylon bolt. I don't mind nylon spacers, but the actual stack bolts NEED to be steel, or preferably titanium. After building, and crashing countless micro quads, I can tell you that nylon stack bolts will break with almost any type of forceful crash, or roll. I replaced my M2 nylon flight stack bolts to titanium right away... My second biggest, and last real gripe I have with this micro is the lack of any real attention to the frame. The carbon is a decent quality, and I appreciate the 3mm thickness, but Diatone did not do any sanding, or edging of any kind. I'm certainly not saying I'm expecting the fit and finish of a 100$ frame, but rough and sharp cut edges, with sparring carbon slivers around screw holes is a bit sub-par... Diatone provides a much better fit and finish on their frames on larger models, so I'm not sure why they skimped on this one? My OCD couldn't take it, and I had to take it apart, and sand the frame... If a couple of these issues were addressed, this would definitely get upgraded from "almost perfect" to "perfect"... All of this being said, I'd buy another one in a heart beat! :)
    4 stars because it's not perfect, and I'm a honest reviewer. 5 stars is reserved for those "perfect" products. You're close on this one Diatone! :) (Posted on 9/13/2018)
    Excellent "first step up from plastic" beginner level drone!!! Review by Chris M
    The GT R90 was my first step beyond the plastic frame bind and fly drones and I am extremely impressed!!! My home field has approximately 4 acres of open air and I find the GT R90 to be nearly perfect for this area and my skill level. The GT R90 is nimble and small enough for proximity flight through the wooded areas and powerful enough to easily loop in the open. My GT R90 has also been much tougher than I ever imagined a drone could be. On at least 5 occasions I have crashed so hard that I immediately thought "it's going to be in a million pieces" only to plug in a fresh battery and maybe change a prop and be back in the air. With this drone I feel like I have stepped beyond the toys and into the realm of serious and quality fpv flight. (Posted on 7/30/2018)
