The Futaba 750 is a wonderful gyro and made even more so because of how it integrates with Futaba transmitters. Because Futaba made both the FBL unit and the TX, the software for each meshes extremely well. It's child's play to change head speed or gain at the field. Futaba wrote the manual for the FBL unit, receiver, and the transmitter so setup flows nicely. Going on, the Futaba on-board control box seems to simplify the process of finding a really good flight setup. With the 750 there seems to be far few questions to be asked and answered to end up with a really great flying model.
Using my Futaba 16szh and was curious what advantages there are to using the CGY 750 over the MSH Brain 2 for sport/scale type flying?
I currently use my iphone for Brain 2 fbl tuning and it works well.
I have 4 of them installed in everything from electric 450s to 700 class glow models. They all fly fantastic.
The 750 is no longer available. Its replacement, the 760, isn't really competitively priced. At nearly $500 it is almost twice as expensive as the most expensive alternatives. In fairness, the 760 does include an integral Futaba receiver with FASSTest capability. A clear plus and since a similar standalone receiver would cost $100, it must be taken into account when looking at the current Futaba FBL unit.
The iKon is also a fantastic FBL unit and offers some considerable advantages. First and foremost, it's a great gyro. Unlike the 750, it almost entirely ignores the menu structure of the transmitter. It only needs input from 8 channels and little else from the TX. For me, most heavy setup work is done on my laptop's large, clear, bright, 4K, touch screen. As you noted, Bluetooth programming is a very nice option and I use it at the field when I don't want to drag my laptop out. The iKon has some very nice logging options to include fault logging and vibration logging. It offers a simplified setup system plus, for those willing to take the time, it offers access to more in-depth PID values. The HD (Heavy Duty) unit I'm currently using offers a superior power input connection and integrated fail-on switching.
Both the 750 and the Brain/iKon are great gyros and I am comfortable recommend both to friends.
