HPP-21 Plus Digital Servo Programmer

Haven't re-programmed my heavy duty antenna tracker digital servos or the digital tail rotor on my tricopter yet but looking over the device it seems to be a well made device for this purpose. And to my surprise the instructions WERE NOT in Chinglish but real well written English. A welcome surprise after trying to decipher some of this manuals made in Asia. The only negative is that HiTec seems to spend a lot of money on fancy packaging that they could use to lower the costs of their quality products.

I purchased this elsewhere but simply put, avoid this thing. The software on modern PCs is unusable. They blame it on Korean servers which is bunk. They are unwilling or unable to update their code. Even as a stand-alone device it is a hassle. Save your money and buy a modern servo programmer.

The software that runs it is not in the install, its a visual basic plugin if you download it, it won't register so I'm stuck using it as a stand alone

okay

if you like Hitec servos this is kind of a no-brainer. you can program most servo parameters. and for me, the great thing is I don't have to fiddle with a programming interface on the PC. this goes in the tool-box and can be operated easily anywhere.

I absolutely love this tool. It's not only useful for servos, but for calibrating ESC + Brushless Motors.One warning: these prices are more than double what I paid. The listing that I purchased from no longer exists. If I could prove that these sellers were colluding to drive the price up, I would report them.

Great product ,made it easy to set up servo end points. Only problem was the instructions . The instructions were hard to follow, I had to go to YouTube for help.

Good programmer device but UI is not exactly easy to use.
