ZTW Gecko 125A ESC with 8A SBEC
ZTW Gecko 125A ESC with 8A SBEC - ZTW4125201
This ZTW Gecko series ESC is a high-quality, efficient brushless electronic speed control with an integrated switch-mode BEC. It can operate without the need for a separate receiver battery to power your servos and receivers saving you weight and simplifying your electronic connections. The Gecko series includes an aluminum heat sink body which is lightweight and helps dissipate heat more efficiently. The BEC on the Gecko has been specifically designed to support higher current applications to eliminate the possibility of unwanted shutdowns, and it is also capable of supporting simultaneous multiple servo operations typically found in large-scale airplanes and CCPM equipped large-scale 3D helicopters. If you are looking for a top of the line, full-featured ESC at a competitive price, the ZTW Gecko is the logical choice.

ESC not capable
I bought two of these and had to return them to Motion RC. I tried them with Leopard motors and found that at high throttle and load, the ESC would loose sync with the motor and mis-commutate. This was especially true with a rapid throttle move. If you then went to zero throttle and took it back up, usually around 60% it would cut-out. I tried updating firmware and also adjusting timing settings, all without achieving the desired results. I tested the setup on the ground before going to the air. Doing the ground testing saved the airplane. When I used a Castle Creations Talon 90 or a FMS 70A ESC to drive the motor, I had no problems at all. The drive current was maxing at about 68A, but that is well below the 85A limit. Perhaps if I only needed to go to 50A, maybe it would have worked. Maybe the Leopard motor was a bad match for this particular ESC, however, the other ESC's had no problem at all with the Leopards.
This is an outstanding ESC, it is easy to install and operate and very durable!
Blew up on second start
The Gecko looks nice but it blew up on the second power-up. It was trying to drive the Hacker A60-6XS.
Not the right speed control
Not the right speed control for my application
So far this has performed very well.
fixed the over heating problem.
Shortly after writing my review on this esc paired with the freewing 70mm special metal fan i lost the throttle calibration for some reason. I recalibrated the throttle and now it works perfect. It even sounds different. Twenty plus flights,some of them i really poured the coal to it with no problems. Im guessing the throttle cal. being off was messing with the auto timing. I'm also getting 30 seconds more flight time now. The battery isn't getting as hot as it did,so the amp draw must have came down. This is a very powerful combo. Unlimited vertical!!!!!
This esc is recommended for 70mm freewing special metal edf. It can only handle full throttle for 10 seconds and then it over heats and shuts off. Flying at 70% throttle or less with short full throttle runs it works fine and the ubec works well with 8 analog servos and retracts.
It does its job, but consider getting the programming card.
I've had this particular ZTW Gecko ESC in my upgraded FMS 1700mm P-51D Ferocious Frankie on 6S for a couple weeks. Lacking the power of a real warbird out of the box, a popular upgrade to the FMS 1700mm planes is a prop pitch mod followed by upgrading to the FMS kv360 motor available on this very site. The factory 85 AMP FMS ESC couldn't handle the resulting ~100 Amp load, so I replaced it with this ESC on the basis that an 85AMP from the same Gecko lineup was doing splendidly in my Extreme Flight 60" Edge 3D plane with a 4315-480kv Motrolfly motor on 6S. But this 125A ESC out of the box didn't work right: It had major timing issues under load when paired with the FMS motor (worse with the scale 4-blade prop on it), and google results indicated similar issues with Motrolfly, Hacker, and others. Fortunately, with the ZTW Gecko Program Card in hand, plus the PC software which is available on the ZTW website, and a firmware update, the issue was fixed. But the process is somewhat dubious. Use at your own risk. Google for a ZTW Gecko firmware update for timing issues hosted by Altitude Hobbies on RCGroups; read it carefully and download the correct file. Then use the PC software and ZTW Program Card to make the update. I'd feel better if the firmware was on the ZTW website and not on an internet retailers google drive, but that's just the way it is as of this review. But I've successfully flown the plane without issue ever since. Fly safe!
