FlySky FS-GT3B
I would like to get some opinions on this following unit, the FlySky FS-GT3B if anyone has one.
Just to get you up to speed:
I am looking for an upgrade for my RC18t, it currently has a Futaba 2-ch AM system and I want something a little more current. To be honest I wasn't even thinking of upgrading because the current setup I have no works just fine, but after seeing the price for that 2.4GHz 3-ch system, I figured what the heck, why not.
So is it any good, or is it to cheap (both literally and figuratively?)
Just to get you up to speed:

RE: FlySky FS-GT3B
I have one and wish I would have bought an MXSport or better.
It works ok; it was cheap and the range is pretty amazing. Also the receivers are crazy cheap (like less than $10 cheap). But....
1. Battery life with the stock setup is dreadful. 2-3 hours before the uber-annoying warning starts up. You can fix that; buy a new voltage regulator from Mouser (~$10), remove the stocker, solder in the new. Take you maybe an hour including getting out your tools, but beware you don't sever the antenna wire like I, I mean my friend, did, 'cause then your range will be about 18' and you might spend an hour or two getting that straightened out.
2. Stock firmware is crazy bad. The expo setting doesn't really work, but worse than that is that adjustment of one setting will throw another setting off. I run the throttle EPA at 100% when I'm driving, but when I let my 4 yo drive I turn both forward and reverse down to ~25%. Fine, right? Except that when you lower the reverse epa it moves the freaking neutral point. ***, over?! I drop REV down and my Slash starts to cog like you're pressing the accelerator 0.01%, which wouldn't be that big of a deal except that then Reverse doesn't work at all. This too is fixable; some way-smarter-than-me user figured out the firmware and now there are updates available. You can either buy the programming gear yourself or send it to someone to have it done. Either way, it'll probably cost $30 to do, and now you've got about $80 into a cheap Chinese radio with no factory support...
Not that impressed, but plenty of people love them.

Not so good for boats?
I thought I might use this to replace the system in my Aquacraft Reef Racer 2, which, like many boats, uses a brushed motor. Therefore needed a brushed motor ESC. Turnigy makes one for this application, but it has no reverse function (primarily for airplanes). Therefore, the ESC sees the GT3B throttle as running continuously from full reverse to full forward - so the default "null" position on the Tx throttle trigger applies current to the motor. The end point and trim adjustments do not appear to have enough range to neutralize the "reverse" range on the throttle, bringing the end point down to the "null" position. And mechanically, there's no way to simply move the throttle spring to hold the throttle all the way in reverse as its starting point, which would make it work for the boat.
Options are to buy a Viper brushed ESC for boats, or replaced the brushed motor with brushless and use a Hobbywing boat ESC. The former is the simplest, and both mods would run about $30.
Anyone have a suggestion on programming or modifying the Tx to avoid more investment on an otherwise cheap-o boat?
