(this rambles -- tough it out) I cannot tell if that Tarot frame includes a power distribution board -- I suspect it does not. If you're already ordering from Banggood, here's a link: http://www.banggood.com/JK-Dual-BEC-ESC-Power-Distribution-Board-With-LED-100A-p-932720.html The power...

Is the best way to spin just one motor to connect the ESC to the receiver channel for throttle? I wonder if there is a tool that will spin a motor at a selected RPM, or selected voltage and I can do the math based on kv? Maybe sort of like an ESC programmer? I'm going to either have to deal...

The 3S lipo battery runs the motors much better, but they were still scrambled as to channel, and didn't work right connecting receiver directly to ESCs. Scrap Turnigy, in comes Taranis. Things working better, but these Turnigy motors are far out of balance, or the grub nuts are defective (or...

After further investigation it seems SBUS (sometimes called S.BUS, other times S-BUS) is from Futaba and has become a sort of standard. It is a BUS, but the devices do not daisy chain -- they get assigned a channel first, then connected into Y-cables or "hubs" (which HobbyKing doesn't sell)...

I have a telemetry radio as part of my ArduFlyer 2.5.2 "kit". It connects to the controller at the I2C port. So that will transmit telemetry back to a laptop at 915MHz. The FrSky GPS "sensor" appears to BE a GPS (but they don't tell you if it's a NEO or LEA), but it doesn't feed my flight...

The best thing about the 9x is that you don't lose much when you dump it. Even with the back light the low-res screen is hard for me to read, and without PC config software, setting up models is a chore. I'm not shedding any tears -- I know I'll be a lot happier with the Taranis! The display...

Those motors look fine from a spec point of view, but the shafts are a bit odd (custom). Are you planning to use matching "keyed" props? I'm not familiar with that "flat, slot" configuration. I know if you hit something, it's better to have the prop spin a little on the shaft, than have the...

There are three wires connecting the motor to the Electronic Speed Controller. When you fire the motors up the first time, knowing what direction you want each to spin. If any motor doesn't spin in the desired direction, and two will not, you reverse any two wires of the three. That reverses...

Well, that was FUN! I got the backlight kit installed, the + & - buttons switched and the firmware wires terminated to a plug and on the next closed-case test, the MENU button no longer did anything. The EXIT button produced the menu on a long press. I can feel the momentary switch actuating...

Then you need a radio/receiver, servo leads, a 3S lipo, a charger (I got the Turnigy AccuCel6 and I like it), I'd get a 5v BEC to power the KK2 & receiver. It looks like the motors and ESCs are both terminated in 3.5mm banana connectors, but you'll have to solder the two power leads of each to...

I don't know if the controllers you like to use (Naza?) use "Mission Planner" or something else, or if you routinely use telemetry radios, but here's a video I found informative on evaluating APM data. If you had such data from the flight where the GPS (or something) allowed the quad to...

Last week, I decided to get a small RTF to do some indoor practicing. I started with the Udi U830A, a nano 2.4GHz quad with a plastic cage over the props. I found it too squirrely to control, so I took it back and traded up for the U816A on Friday -- a little larger, so it's a slower squirrel...

Did you consider the other two popular firmwares? OpenTX is coming up behind ER, but "gruvin" is still popular too. If so, what made you select ER? I just prepared to flash mine too. But I soldered the leads rather than buy the Smartie Parts board. I figured I can use the USBasp for other...

Yes I think GPS is great, but we may rely on it too exclusively. I may allocate one of my six APM modes to MANUAL in response to this, and other reports I've seen in YouTube videos and on forums. It would be interesting to know what logical sequences the controller boards use to make flight...

Why did the GPS lock drift?

No it's not normal. It may be a bad connection internally, or a short. Normally in a crash, a small quad will shut down to protect the motors and props, but yours is going a step further. Have you asked the vendor? Another option is to find the Flyin' Ryan review of the X1 and post your...

Now that you have the frame, you can look at YouTube videos of other builds on that frame. Here's one: 2212, 920kv motors, 8" props, 3S lipo, 30a ESCs. Stay in that motor/prop/S range with compatible parts and you'll do fine, then match the ESCs to the motor requirements. At 450, you're not...

Can you have the GPS up with the canopy on? Not in any videos I see.

The Open 9x crowd has improved firmware for the Turnigy 9x and all other variants of this radio. That includes the FlySky, Eurgle and a few others. Their main Wiki page is: http://openrcforums.com/wiki/index.php/Main_Page The forum index is here: http://openrcforums.com/forum/index.php With...

You're welcome! And we all want to see your quad fly. Maybe if you put pieces of "pool noodle" on the land gear legs, it will land easier and maybe even float.
