I am going to toss my $0.02 in here since I haven't seen much mention of it.
Spartan Vortex.
I've been flying this FBL unit exclusively for three years now.
Very easy to set up, a little more advanced to tune it, but well worth the effort when you get them locked in. It has one of the best FBL based governors on the planet, and the price tag is very nice for the VX1E.
The only drawback is that you must use satellites only when using Spektrum systems if you want to use the governor. However, the Vortex has a built in throttle fail safe for this, and has two Satellite Rx ports built into it.
VX1, and VX1N are discontinued, but can be found online in the used market easily. The VX1 has onboard vibration analysis and storage memory for vibration logs (very handy). Both of these require the use of a dataod to use them with the Studio software or to connect them to USB for updates.
The VX1E (Current standard unit from Spartan) has a built in USB port, but sacrifices Vibration analysis features, and has the standard sensor ICs that every other FBL unit has on the market. VX1 and VX1N have higher quality sensors.
Angelos is working on the VX2 right now as the predecessor, and this will have many of the features such as Bailout/Rescue and telemetry (not solid on telemetry yet, but it was mentioned)
All Spartan Vortex units do have the capability of Jeti integration, and can be programmed through a DS-14 Tx or higher. This is a good feature to have as it eliminates the need for the datapod or studio software completely, as setup and adjustment can be done from the Jeti Tx at any time.
I know this thread is an older thread, but I wanted to give my opinion on what I consider to be the most user friendly FBL unit out there.
